Extracting gold, silver and different commodities from discarded items has commercial, geopolitical and environmental advantages for the EU.

Dr. John Bediako has traveled the globe his complete lifestyles. Born and raised in Ghana, he earned his PhD in South Korea and is now operating in Finland on a big problem going through Europe: reusing digital waste, or e-waste.

“It is a scorching matter,” stated Bediako, a researcher on the School of Engineering Sciences at Lappeenranta Lahti College of Generation. “We will be able to blank up the surroundings and, on the similar time, gas our financial system. That amazes me.”

Extraction problem

Europe’s high-tech financial system depends upon uncooked fabrics comparable to cobalt, platinum, palladium and gold, which might be present in the entirety from cellphones to sun panels.

Alternatively, those fabrics are frequently extracted in puts a long way from Europe and in techniques which might be destructive to the surroundings.

For instance, China provides 97% of the Eu Union’s magnesium, which is utilized in steel merchandise that should be sturdy however light-weight comparable to bicycles, ladders and laptops. China may be a supply of uncommon earths utilized in magnets, an integral part of electrical automobiles and wind generators.

One answer for Europe is to recycle essential uncooked fabrics so long as they are able to be extracted from disposed merchandise. However this is more straightforward stated than finished.

Some elements are found in such small amounts that they’re tough to take away. Or frequently remedy processes don’t permit entire elimination.

Scientists like Bediako are discovering new techniques to show waste piles into exact gold mines.

Geopolitical purpose

But even so reaching environmental advantages, luck in this entrance would toughen the EU’s geopolitical place by means of making it much less depending on imported uncooked fabrics that still come from Russia, the Democratic Republic of the Congo and different international locations.

“Europe lacks numerous treasured metals,” stated Dr. Elisabet Andres Garcia, venture supervisor at TECNALIA, a non-public middle for carried out analysis and technological building in San Sebastian, Spain. “The easiest way to stop Europe’s growth from being depending on out of doors international locations is to recycle.”

The Russian invasion of Ukraine in 2022 ended in an important upward push within the costs of palladium, a comfortable silvery-white steel this is principally mined in Russia and used within the manufacturing of automobiles, digital elements or even dental fillings.

To be sure that it could retain get right of entry to to those fabrics, the Eu Union is that specialize in its personal manufacturing and analysis.

In March 2023, the Eu Fee moved to spice up the EU’s home manufacturing of elementary items thru a draft regulation. The proposed law, referred to as the Important Uncooked Fabrics Act, units goals of a minimum of 10% for restoration, 40% for processing and 15% for recycling of those fabrics in Europe.

Gold retrievers

In parallel, the Eu Union depends upon earlier analysis within the box of digital waste extraction. One new venture has gained EU investment to spice up the restoration of treasured metals together with gold, platinum and silver.

The venture, referred to as PEACOC, is coordinated by means of Andres Garcia and can run for 4 years till the tip of April 2025.

It comprises 19 members from 9 international locations: Austria, Belgium, France, Greece, Italy, the Netherlands, Spain, Turkey and the UK. Individuals vary from the analysis arm of Italian automotive corporate Fiat to a Dutch producer of 3-d printers for ceramics and metals referred to as Admatec Europe.

“We’re operating to increase the waste streams that we will be able to procedure,” Andres Garcia stated. “We now, as an example, recycle some circuit forums from which we will be able to download treasured metals comparable to gold.”

For instance, a circuit board from a damaged tv set may well be flooring up and run in the course of the chemical processes that PEACOC pioneered.

This remedy in the long run ends up in the extraction of treasured metals from the waste, one thing that up so far had simplest been finished on a restricted scale. Those processes had been evolved in a prior EU-funded venture referred to as PLATIRUS and are actually being designed for better processes.

DIY waste crushing

Bediako is that specialize in smaller, however no much less essential, volumes as head of every other EU-funded analysis venture. It is referred to as IONIC BARRIER and runs for 2 years till January 2024.

Thru it, Pediaco is attempting to increase new chemical processes to extract essential fabrics from digital waste when just a small quantity is provide.

“Infrequently the focus of goal metals is so low that present strategies are not able to seize them,” he stated. “With the generation I’m creating, we will selectively get better some elements even if they’re present in very low concentrations and in advanced combinations.”

Bediako is refining his procedure within the lab.

It crushes digital waste by means of hand, separates the plastic from the steel after which passes it thru a number of steps: immersing the steel in an answer, filtering the ensuing aggregate and treating the pieces with absorbents.

On the finish of the method, all that is still is gold, palladium and platinum.

Bediako when put next the quantities of gold present in discarded telephones and within the flooring to underscore the price of his analysis.

“There are about 350 grams of gold consistent with ton of digital waste from telephones,” he stated. “For those who extract the ore from the bottom, you can simplest to find between 5 and 30 grams of gold consistent with ton. It is sensible to beef up our recycling functions.”

Eyes on Athens

The primary query is whether or not those processes will also be performed in financial and environmental techniques.

In different phrases, researchers want to make their processes environment friendly sufficient to compete with mining with out harming the surroundings.

Below PEACOC, large-scale trying out is scheduled for 2025 in Athens, Greece on the amenities of an organization referred to as Monolithos that varieties and processes automobile catalytic converters. The purpose is to peer if the strategies will also be carried out on a business scale.

“We’re taking a look at a number of techniques to make use of the metals we achieve from recycling,” Andres Garcia stated. “They is also utilized in 3-d printing, and in construction new autocatalysts, however we also are taking a look at production jewellery.”

Something is obvious: Europe can not permit precious sources to lie unused within the numerous piles of waste items generated by means of trendy economies.

“Our high-tech and effort conversion industries want essential new uncooked fabrics,” Bediako stated. “The least we will be able to do isn’t let all this waste move to waste.”

From bone-like scientific implants to more potent, extra fuel-efficient plane portions, complex structural supplies can take a very long time to transport from laboratories to business programs, however researchers on the College of Toronto are harnessing the ability of device studying to hurry up that transition procedure.

“Designing microstructures is an very important step in supplies construction,” says Yu Zhou, assistant professor within the Division of Mechanical and Business Engineering within the College of Carried out Science and Engineering. “However conventional supplies design, which is dependent upon experiments or simulation strategies, can take years—even a long time—to decide the right kind microstructure.”

Zhou and his laboratory group purpose to boost up the invention of latest structural supplies. In a brand new paper printed in Fabrics as of lateZhou’s group describes a brand new complete framework used to fashion the microstructure of Ti-6Al-4V, probably the most broadly used titanium alloy within the aerospace and biomedical industries.

“This paintings may just permit supplies scientists and engineers to find microstructures at unparalleled speeds, just by introducing their desired mechanical houses into the framework,” says Ph.D. Candidate Xiao Shang, lead creator of the paper.

The researchers started by means of coaching two deep studying fashions to appropriately are expecting supplies’ houses from their microstructure. They then mixed a genetic set of rules with deep studying fashions to near the materials-by-design loop, permitting the framework to design optimum microstructures for supplies with centered mechanical houses.

Deep studying fashions are first created to are expecting the mechanical houses of the fabric prior to a genetic set of rules is used to successfully seek for the perfect microstructure of the fabric for the precise goal subject material houses.

“In lower than 8 hours, we known microstructures of titanium alloys that exhibited the top power and top stiffness had to toughen plane structural elements,” says Zhang. “We now have additionally designed a titanium alloy with the similar chemical compositions as prior to however with other microstructures which can be roughly 15 p.c extra like minded with human bone-compatible biomedical implants.”

Researchers had to triumph over many hurdles to broaden their deep studying fashions. This comes to growing their very own dataset of just about 6,000 other microstructures via simulation, a job made imaginable by means of leveraging the huge computing energy of supercomputers on the Virtual Analysis Alliance of Canada.

“We repeatedly encountered eventualities the place our deep studying fashions and/or selected optimization algorithms weren’t acting in addition to we anticipated,” says Zhang. “However we have been affected person and glued to our analysis plan whilst we actively appeared for brand new approaches to make the fashions paintings.”

“Having a look to the longer term, we wish to fortify and fortify additive production era even additional in order that they are able to proceed to broaden this new framework,” says Ph.D. candidate Tianyi Liu, who co-authored the paper with Ph.D. Candidate Jiahui Zhang, either one of whom paintings within the box of steel additive production.

“We’re advancing the standard and reliability of steel additive production, unleashing its possible to in the neighborhood customise the microstructure of fabrics throughout printing,” provides Zhou, a member of the accelerator consortium.

“As an example, with conventional era, it’s virtually unattainable to customise biomedical supplies for various sufferers. However we wish to permit the way forward for personalised biomedical implants by means of making it imaginable to print the form and mechanical houses that fit a affected person’s wishes in only a few days.”

Scientists accumulate lively cathode fabrics for lithium-ion batteries at quite low temperatures

Scientists collect active cathode materials for lithium-ion batteries at relatively low temperatures

Response trail for the aqueous glide procedure to shape layers of lithium cobalt oxide (LiCoO).2) at 300°C. credit score: Inorganic chemistry (2023). doi: 10.1021/acs.inorgchem.3c01704

The layers of lithium cobalt oxide, a key element in lithium-ion batteries, are fabricated at temperatures as little as 300°C and for classes as brief as half-hour.

Lithium-ion batteries (LIB) are essentially the most often used form of battery in shopper electronics and electrical automobiles. Lithium cobalt oxide (LiCoO2) is the compound used for the cathode in LIB for moveable electronics. Historically, the manufacture of this compound calls for temperatures in far more than 800°C and takes 10 to twenty hours to finish.

A workforce of researchers at Hokkaido College and Kobe College, led by way of Professor Masaaki Matsui at Hokkaido College Faculty of Science, has evolved a brand new technique to manufacture lithium cobalt oxide at temperatures as little as 300°C and for classes as brief as half-hour. Their findings had been revealed within the magazine Inorganic chemistry.

“Lithium cobalt oxide can generally be manufactured in two bureaucracy,” Matsui explains. “One shape is the layered rock salt construction, referred to as the high-temperature section, and the opposite shape is the spinel framework construction, referred to as the low-temperature section.2 It’s utilized in lithium-ion batteries.

The usage of cobalt hydroxide and lithium hydroxide as beginning fabrics, with sodium or potassium hydroxide as components, the workforce performed a chain of high-precision experiments underneath other prerequisites to synthesize layered LiCoO.2 Crystals. The method was once referred to as “procedure hydroflow”. They had been additionally in a position to decide the response pathway that ended in the formation of the layered crystals.

“Through figuring out the response pathway, we had been in a position to spot elements that promoted the crystal expansion of the LiCoO layers2“In particular, the presence of water molecules within the beginning fabrics very much progressed the crystallinity of the overall product,” Matsui stated.

The workforce additionally measured the electrochemical homes of the LiCoO layers2indicating that they had been best marginally not so good as that of commercially to be had LiCoO2 It’s manufactured by way of the standard high-temperature way.

“This paintings is the primary experimental demonstration of the thermochemical steadiness of LiCoO layers2 “At low temperatures underneath ambient drive,” Matsui concludes. “Our building of this aqueous glide procedure will allow power saving measures in more than a few ceramic manufacturing processes. Our fast subsequent steps shall be to optimize the aqueous glide procedure in keeping with our figuring out of the response pathway.”

The New York Tidal Power Undertaking helps researchers discover recyclable fabrics for renewable power generation

The New York Tidal Energy Project is helping researchers explore recyclable materials for renewable energy technology

A brand new subject material may just help in making blank power applied sciences, such because the tidal power generators proven right here, extra sustainable. Credit score: Paul Komosinski, NREL

On a grey, foggy day in Would possibly 2021, a rusty barge carried 3 shed-sized tidal generators — every fixed at the issues of a triangular metal body — throughout New York Town’s East River. Despite the fact that the 3 generators seemed an identical, one was once a double model, constructed from a wholly new form of resin that might assist decarbonize even probably the most sustainable blank power applied sciences, comparable to tidal power generators.

“We’re operating to decarbonize the power sector, however we additionally want to decarbonize thru decarbonization,” stated Robyn Murray, a analysis engineer on the Nationwide Renewable Power Laboratory (NREL).

Resins are very similar to glue. They bond portions of alternative fabrics, comparable to fiberglass, to construct the sturdy composite fabrics utilized in many tidal and wind turbine blades. However a few of these adhesives, like the preferred epoxy, are one-and-done: as soon as heated to shape laborious, sturdy blades, they can’t be simply transformed and recycled.

However Murray and his group have designed a brand new subject material, referred to as a thermoplastic resin, that isn’t most effective more uncomplicated to recycle, it’s also higher fitted to surviving the corrosive saltwater of the East River — or another promising web page for tidal power. This implies the brand new resin is usually a win-win in carbon elimination if the fabric can end up its possible in the actual global.

and I did.

For the six-month East River deployment in 2021, NREL partnered with tidal power corporate Verdant Energy during the Roosevelt Island Tidal Power Undertaking. The Verdant Energy instrument, which has 3 generators — two product of conventional epoxy and one in every of NREL’s thermoplastic resin — set a U.S. report for the {industry}, producing about 312 megawatt-hours of energy, the second-highest quantity produced by means of any offshore power venture It is sufficient to energy just about one thousand properties.

The main thermoplastic composite blades now not most effective survived sawing, they did so conveniently. The blades didn’t endure any structural harm whilst sawing, in contrast to their epoxy opposite numbers. The fabric maintained its energy ahead of e-newsletter as neatly. Despite the fact that a tool factor averted the NREL group from saving one of the most knowledge accrued by means of sensors at the turbine blades, all in their knowledge assortment {hardware} — together with the sensors and the instrument used to retailer the knowledge — survived the cruel salt water.

“Anytime you do one thing for the primary time, you more or less be expecting it isn’t going to move neatly, even supposing you do your perfect to handle all of the dangers,” Murray stated. However excluding a last-minute programming factor and the pandemic that averted NREL participants from touring to New York Town, the enjoy went higher than anticipated. “It was once for sure encouraging to peer how neatly the units carried out underwater,” Murray stated.

However the river was once only the start.

Again within the lab, Paul Murdy, Robin Murray and group participants are operating exams to peer if recyclable thermoplastic resin is usually a treasured subject material for tidal and wind turbine blades or different blank power applied sciences. Credit score: Joe Del Nero (left) and Werner Slocum (proper), NREL

Now, again on the lab’s house in Colorado, Murray and his group have already minimize their thermoplastic blades off the axis and minimize them into what they name coupons, which might be oblong items as small as stamps or as massive as magazines.

Although the blades continue to exist the river, the group needs to search out the verge of collapse — actually. As an example, Murray and her staff plan to glue clamps to a chit that may pull and pull and pull till the fabric breaks off. Different coupons will probably be soaked in salt water to peer how deeply the water penetrates the fabric over the years and whether or not this saturation impacts the energy of the fabric.

“We do not in point of fact know the way saturated it was once after we took it out of the water,” Murray stated. Murray defined that in most cases, her group would weigh the blades ahead of and after deployment to peer how a lot water they absorbed. However for the reason that blades have been already hooked up to the large axis, they have been not able to get a correct size in their weight.

“And that’s the reason too unhealthy,” Murray stated. “If there are issues we see within the take a look at effects, is that as a result of water were given into them or is it only a herbal exchange that occurs to the fabrics?”

That is what she and the group try to determine now. “We in point of fact want to absolutely know the way the fabric plays ahead of we will be able to come to a decision whether or not it is price seeking to undertake it as an {industry},” Murray stated.

And it does now not by myself cope with this large, industry-changing query.

“Now we need to do the investigative paintings,” stated Paul Murdy, a mechanical engineer at NREL and Murray’s spouse in reducing, reducing and soaking new marine power fabrics, together with thermoplastic blades. To this point, thermoplastics have carried out neatly, Mordi stated. Now, by means of processing the fabric, they are able to analyze how the fabric differs from conventional fabrics, comparable to epoxy compounds.

Despite the fact that Murray sees thermoplastics as a possible technique to construct extra sustainable, recyclable composite fabrics for wind and tidal turbine blades, she additionally recognizes that those fabrics might not be your best choice for all power packages.

The fabric has a tendency to creep, because of this it may well slowly deform over the years. Although people put numerous stuff underwater, there is nonetheless so much to be informed about how more moderen fabrics, like thermoplastic composites, deal with a difficult salty surroundings.

Those post-deployment exams may just assist Murray and his group, in addition to marine power firms, higher know the way thermoplastics hang up. This data can assist resolve whether or not they’re a just right are compatible for wind and tidal generators and even different renewable power applied sciences.

“It is a step in the suitable course towards higher fabrics for the power {industry},” Murray stated. “And I believe there will probably be a spot for thermoplastics. It is only a query of what constructions they will be in.”

She and different fabrics professionals at NREL are exploring different choices as neatly, comparable to recyclable epoxy that may be plant-based and may just compete with petroleum merchandise.

“These days’s fabrics are emerging to the problem with regards to structural efficiency,” Murray stated. “However they’re most often derived from fossil fuels and aren’t recyclable. So, if it is thermoplastics or different recyclable fabrics that take off sooner or later, it issues the place our fabrics come from.”

Multi-stability mechanical fabrics advance design, production, and programs

Multi-stability mechanical materials advance design, manufacturing, and applications

The 3 innermost leaves include 3 bistable core devices. The center episode describes the fundamental preparation strategies for metastable metamaterials: Three-D printing (DIW, FDM, SLA, PolyJet, PBF, PμSL, TPP), reducing (mechanical reducing, laser reducing) and die casting. The outer ring describes doable programs of multistable mechanical fabrics: calories absorption, cushy actuator/robotic, mechanical garage/good judgment actuation, and wave keep an eye on. Symbol credit score: Rui Xu, Quanqing Chen, Jiaping Solar, Yulong He, Xin Li, Minghui Lu, and Yanfeng Chen.

Researchers from Nanjing College reviewed the newest analysis growth within the design, fabrication and alertness of multi-stable mechanical fabrics with the exceptional skill to change between more than one secure configurations beneath exterior loading. Reaching reusability puts those leading edge fabrics in quite a lot of engineering programs, together with calories absorption, cushy actuators/robotics, mechanical garage, good judgment operations, and wave keep an eye on.

Revealed in Global Magazine of Excessive Industrialization,This analysis starts by way of summarizing and classifying not unusual ,bistable modules, thus making a foundation for comparing ,bistable steadiness – a side that has no longer in the past been ,explored in current analysis. The mechanical houses of the bistable buildings are then tested from an calories standpoint.

Within the box of producing multistable mechanical prosthetic fabrics, the analysis no longer most effective introduces conventional subtractive production strategies, akin to reducing, but in addition highlights state-of-the-art subject material processing tactics, together with Three-D and 4D printing.

Because of the outstanding houses of multistable mechanical fabrics, their software doable extends broadly to spaces akin to calories absorption, cushy robotics, and wave keep an eye on, amongst others. In the end, the paper delves into the research of long term analysis tendencies and demanding situations that lie forward within the box of multistable mechanical fabrics.

“The flexible mechanical fabrics are lovely cool – they may be able to transfer between other secure paperwork, making gadgets reusable. As well as, their calories boundaries are helpful for soaking up and storing calories. Once they transition from one secure state to some other, they briefly unencumber pressure calories.” , making Ming Hui Lu mentioned: “It’s tremendous environment friendly for quick paintings. And the most productive phase? It does no longer desire a consistent energy provide for stable state deformations. “It is also wealthy in deformability and will do a wide variety of cool issues.”, a professor on the College of Engineering and Implemented Sciences at Nanjing College and lead writer of the learn about.

“Those houses make multistable mechanical fabrics promising for quite a lot of programs in lots of fields, akin to cushy actuators/robotics, mechanical garage/good judgment operations, calories absorption, wave keep an eye on, and so on.,” Lu added.

“We will be able to in finding bistable buildings far and wide, each in nature and in our on a regular basis gadgets. The leaves of a Venu flytrap flip from ‘open’ to ‘closed’, or a hummingbird’s beak closes in only some milliseconds to clutch a delectable insect. “Even on a regular basis gadgets akin to keys, bottle caps, pen caps, plastic buckles, cable ties, bouncy toy balls, measuring tape, and hair clips use bistable designs,” mentioned Shen Li, professor of the College of Mechanical Engineering at Nanjing College.

“We categorized those not unusual bistable buildings into 3 classes, which fills the distance in earlier analysis. They’re: beams, helps, conformal mechanisms, curved surfaces and thin-skin buildings, and different buildings akin to kirigami and snap-fits,” Li mentioned. Constructions.”

Making ready multistable mechanical fabrics is a prerequisite for his or her engineering programs, and there are lots of fabrication strategies similar to those fabrics.

Subsequent, he defined to me, “But even so conventional subtractive production like reducing (system or laser) and die casting, there’s this new factor referred to as Three-D and 4D printing that has taken off like loopy. This generation has come far prior to now few years.” It is vitally simple to create those complicated, multi-stable mechanical fabrics. Particularly in the case of printing them with excessive precision or making them in several sizes, Three-D and 4D printing get some severe benefits.”

As for the longer term building of multistable mechanical fabrics, Lu mentioned, “AI is the recent matter presently, particularly with regards to design, modeling and optimizing issues. So, if we combine just right conventional design and simulation strategies with AI, we will be able to design those metamaterials piece by way of piece.” of cake.It is all about simplifying the method, that specialize in core parameters, and adorning design potency.

“I am very fascinated by the way forward for multistable mechanical fabrics as a result of there are some nice new production tactics. Take nanoscale Three-D printing for instance. Such things as PμSL and TPP had been game-changers, permitting us to create those small multistable fabrics buildings.”

“Plus, after we use first class fabrics, complex Three-D printing and post-processing tactics, we do not simply lead them to glance just right, we lead them to sturdy, too—energy and all that jazz. It opens the doorways to the usage of those extremely secure mechanical fabrics in a wide variety of fields.” “Like aviation, medication, electronics and robotics, we will be able to even make those fabrics the usage of cushy fabrics and 4D printing generation. This implies we will be able to keep an eye on them with all types of such things as electrical energy, gentle, temperature, pH ranges, solvents, humidity and magnetic fields.”

The applying of multistable mechanical fabrics additionally faces quite a lot of alternatives and demanding situations. “Relating to soaking up calories, they don’t seem to be as just right at soaking up calories in comparison to standard fabrics.”

“However there’s a resolution for that! We will be able to adjust the design, use fabrics with prime calories density, combine them with common calories absorbers, or even create multi-stage energy-absorbing setups to give a boost to issues. We will be able to make those buildings bend and flex on command by way of extruding positive fabrics that react With exterior alerts. This extraordinarily speedy form exchange makes it preferrred for powering cushy robots and motors in a flash.”

“Those bistable buildings can retailer information as binary states with out requiring energy. This implies they may be able to take care of some very harsh environments like prime radiation, sizzling warmth, or excessive power. And while you mix them with mechanical computing, you have got machines that may suppose,” Lu mentioned. “We each and every adapt to the entirety on our personal. “Do not be shocked to look those mechanical brains shrink to the micro- and nano-level with the appearance of micro-Three-D printing generation.”

Up to now decade, scientists have proven nice enthusiasm for analysis into multistable mechanical fabrics, and feature completed exceptional effects. The crew believes that the continual growth of multistable mechanical fabrics principle and production generation will very much fortify its software in additional engineering fields.

She stated: “This discovery has the prospective to lend a hand deal with the worldwide power disaster and give a contribution to the battle towards local weather alternate. Just about two-thirds of the power generated international is wasted as warmth. Changing even a portion of this wasted warmth again into helpful electrical energy would make Lend a hand make certain sustainable power provide and scale back carbon emissions.

“The United Kingdom is predicted to want two times as a lot electrical energy in 2050 than in 2020. The possibility of thermoelectric era has been recognized for numerous years, however turbines are lately pricey and now not very environment friendly. The use of new thermoelectric era that would lend a hand It’s inexpensive and extra environment friendly to transform the 48 terawatt hours of waste warmth the United Kingdom produces each and every 12 months into electrical energy and may lend a hand us at the trail to web 0.

Watches and vehicles

This step forward may now not simplest have sure penalties for the battle towards local weather alternate, however may additionally make a distinction in one of the most gadgets and machines we use each day.

At the moment, thermoelectric gadgets and turbines are pricey and simplest used for specialised packages (such because the Voyager probes despatched via NASA to discover house outdoor the sun machine). Then again, the advance of latest thermoelectric turbines will have a vital affect on wearable gadgets, akin to good watches, as present era depends upon batteries that require common recharging. Getting rid of this requirement, via harvesting frame warmth to generate power, may now not simplest be extra handy but additionally make wearable era extra dependable in necessary packages, akin to tracking the well being of frail or aged sufferers.

This construction might be recommended to the automobile business, permitting automakers to increase thermoelectric turbines that use waste warmth to rate the batteries of electrical or hybrid automobiles, expanding their potency. Factories that produce glass, metal or cement, which might be lately carbon extensive and generate massive quantities of waste warmth, may additionally take pleasure in this era.
