Researchers claim photoluminescent aerogel has a visible light reflectance of 104%

A team of chemists and materials scientists at Sichuan University, in China, has developed a photoluminescent aerogel with a visible light reflectance of 104%. In their study, published in the journal Science, the group created their aerogel from readily available biomass. Changyu Shen and Xianhu Liu, with Zhengzhou University, also in China, have published a Perspective piece in the same journal issue outlining work surrounding the development of polymeric passive radiative cooling materials and the work by the team on this new effort. As the climate warms, scientists are looking for ways to help people stay cool. One avenue of research is the development of passive radiative cooling materials—these provide cooling abilities due to their nature rather than via a process.

Aerogel is sometimes referred to as “blue smoke” or “solid smoke”. It is as delicate as a flower, yet durable enough to withstand extreme environments. (NASA)

Wood has a variety of outstanding properties due to its oriented pore structure, among which the low thermal conductivity has attracted researchers to develop wood-like aerogels as thermal insulation materials.

This material can withstand a high temperature flame of 1,300 degrees Celsius and not be burned through in at least 20 minutes, according to the research team led by Yu Shuhong from the University of Science and Technology of China.

The researchers used the method of surface nanocrystallization with natural biomass and minerals as ingredients to make the surface-inert and weakly interacting wood particles better assemble to construct the aerogel.

Coming Back

A little obsessed with re-entry as a concept these days. The idea of a long cold journey that is arduous, but safe, and all that is required is to endure... followed by a few minutes of being baptized in searing white plasma, no radio communications, some outer layer you thought of as "yourself" being excised as an inevitable cost, a mostly-ballistic trajectory.

It's "mostly ballistic": once you pick your lane, once you shoot your shot, you make the last few trim adjustments with your hydrazine-or-whatever thrusters: and now you've placed your bets. There's not really anything you can do on re-entry where adding energy will help, because the fundamental problem is one of shedding energy. The speed that got you through the journey is now a hazard. You have to re-acclimate to moving slowly. You have to come back, adopt a speed that is more favorable to atmosphere and breathing and humanity, and that means aerobraking. Every part of that is basically deterministic though: too steep and the heat builds up too fast and cooks you; you couldn't absorb the change fast enough. Too shallow and the exposure to heat over dozens of minutes wears you down: you didn't rip the band-aid off fast enough, you overshot your target, you spent so long getting back to normal that you left yourself vulnerable.

So every re-entry trajectory is this Goldilocks thing where you come back, talk to some experts on the far end and say "what is the best way to finish this" and trust them. The final exam is setting your course, knuckling down, and coming through the short dark window of loneliness to a place where you can open the parachutes and splash down safely, and wait for someone to pick you up and say "welcome home. you made it."

Giving New Meaning to 'Air Bag', This Handbag is the Lightest on Earth

Made from the world’s lightest material, this designer handbag weighs almost nothing at all. Using NASA-developed aerogel, the bag is made of 99% air, and supposedly feels like carrying nothing at all. Created as a statement piece for Coperni’s 2024 runway show at Paris Fashion Week, the futuristic handbag might not be able to hold much, but it still stole the show. First developed by NASA to…

22, do te doja te mos tregoja shume per veten por ja qe po e bej. Mbase sepse ndihem me e sigurt per faktin qe jo te gjithe e dine shqipen dhe plus jam e bindur qe nje dite do te fshij kete faqe timen sepse nuk du qe te le asgje pezull. Jam ulur ne nje dhome shume te bukur, e rrethuar nga xhama, qe lejojne te duket pamja e natyres qe na rrethon. cuditerisht ky qytet do me kujtoje gjithmone shqiperine. Dje u zgjova ne 6 te mjesit, s'kishte kemb njeriu neper koridore dhe pash nje lidje dielli te papare. Si gjithmone ajo era e ftohte e mgjesit do me kujtoje ato udhetimet ku nuk ngopeshim dot me gjume dhe niseshim ne udhetim per ne jug, per ne plazh. Edhe pse shpeshhere ndodhnin sherre, prap kam kujtimet me te bukura nga ato kohe. Ai ajri i ftohte i mgjesit ne vere, por i durueshem. Ne qe jemi te veshur me rroba te holla, me tuta te shkurtra te blera tek tregu cam. Ajo era e veses, ai malli per nonen qe do e linim per disa dite vetem ne shpi, por ato ndjenja te forta te nje aventure qe te pret. Dhe pervec rruges qe te kepuste fare, ato ditet e bukura ne plazh jane ndoshta nga kujtimet me te bukura qe kam. Nuk lodhem kurre duke i menduar ato mengjese, ku dilnim ne ballkon duke pare gjithe detin para nesh. Aty ndihesha me afer me veten sesa kurre. Prane ujit, deteve, burimeve i kam themeluar kujtimet e mia me te forta, qe do te me shoqerojne pergjithmone ne kete rrugetimin tim. Mbase 22 vjte nuk jane shum por edhe pse prej kohesh jan pergatitur per kete fakt, sikur gjendesh gjithmone pak i papergatitur per kete gje. Sikur goditetesh papritmas dhe ngel cik si i tronditur per nja dy-tre dite. Tani jam veshur holle, dhe une fare rastesisht jam ulur me kurriz nga era e ftohte qe fryn. Keshtu i kaloj une ditelindjet, si dite te zakonshme por perbrenda perpiqem kaq shume te qendroj e qete sepse me shume se per veten, une mendoj per te dashurit e mi. Fatmimresisht Zoti me ka forcuar shume sivjet. Mund te them qe vetja ime e nje viti me perpara nuk do arrinte te me njihte dhe aq shume sepse kam ndryshuar. Pikerisht kete te diele qe kaloi m'u tha nga nje person:"ke ndryshuar shume, por per mire". Sido qe te jete une nuk e bej per te tjeret. E bej vetem dhe vetem per veten time. Askush s'do e dije sesa shume i dua njerezit e mi por kam mesuar se ata shume here do perpiqen te te ndryshojne edhe ty vetem dhe vetem qe te kete qetesi dhe qe te mos kete mosmarreveshje. Nuk e lejoj me mosrrespektin dhe nese e shoh qe nje vend nuk ben per mua, cohem dhe iki. Shume thjeshte. Kam kaq shume per te mesuar akoma por mundte them se s'kam qene asnjehere me mire. Kam kaluar kaq shume sfida, kam rene posht me mijera here saqe ishte sikur dikush po me bertiste dhe une prap nuk po arrija t'a degjoja. Heren e fundit qe u rrezova ishte ndoshta gjera me e dhimbshme qe kam perjetuar ndinjehere. Nuk i'a uroj askujt. Puna eshte qe ai rrezim ka qene aq i dhunshem dhe i dhimbshem sespe me duhej te gjeja forcen tek vetja ime. M'u deshen muaj dhe nje vit i tere per t'u cuar nga aty ku isha dhe m'u desh te merrja nje vendim: Ose do te vazhdoja jeten time duke u shkelur vazhdimisht nga njerezit dhe nga situatat, duke lejuar qe jeta te me perplasi ku te doje ajo, ose do te cohesha nje here e mire, edhe pse duke qare dhe do vendosja vete per jeten time, nuk do te lejoja qe te tjeret te me shkelin dhe te me ulin dhe mbi te gjitha une do t'a drejtoja jeten time, edhe pse ndonjehere do te me duhej te sillesha ashper. Jeta mund te jete shume e padrejte; ka disa njerez me nje shpirt aq te zi dhe aq te lig saqe as nuk u'a merr mendja. Por ne castin qe ti behesh i vendosur, vetem gjera te mira fillojne te te ndodhin. Fillon brenda teje nje ndryshim rrenjesor, behesh i forte si celiku dhe asgje nuk te ndalon dot. Nuk behesh i varur nga askush, ne castin qe fillon te dobesosohesh pak, e ndalon veten dhe i thua:"mos guxo t'a besh prap". Etj etj. Gjeja e fundit qe dua te them eshte kjo: behuni te forte, qendroni prane atyre qe doni sepse perkundrazi nga ajo qe thuhet neper rrjete sociale, izolimi vetem sa t'a shton njenjen e vetmise. Dilni, kenaquni ne kete moment dhe mos i lini gjerat per me vone, sepse ajo dite nuk do vi kurre. Punoni fort dhe kujdesuni per veten. TANI JAM E EMOCIONUAR PER CFAR DO TE ARRIJ TE BEJ KETE VIT

Aerogel-based phase change materials improve thermal management, reduce microwave emissions in electronic devices

Electronic devices are getting more and more complex as they are built to carry out an ever-increasing number of functions. This can be seen in the increased functionality in our personal devices such as our phones, tablets and watches, let alone in industrial devices. However, their growing complexity can lead to performance and safety issues. These issues include device overheating or emitting microwaves that can result in health issues and that can reduce a device's performance and interfere with other devices. Chinese scientists from Beijing Normal University have been working on building shielding for electronic devices using multifunctional composite phase change materials (PCMs) to address these performance issues. PCMs are man-made materials built by combining different types of elements, allowing the creation of a new material with very specific purpose driven characteristics. In this case, the researchers are looking to improve thermal management, solar-thermal conversion and microwave absorption in the electronic devices.

Aerogels Market Analysis: 2022, Global Growth Outlook, Key Developments, Business Share by 2030

Aerogel is a class of synthetic porous ultralight, and dense foam, where the component of liquid is replaced by gas thereby making the lightest solid. The properties of aerogel are – it has low density, shows resistant to high temperature, optical refraction index is low, dielectric constant is high,  high specific surface area, degree of porosity is high, properties of thermal, acoustic, and impact damping. It has the capacity of holding more than 4000 times of weight of its own. The ecological nature of aerogel sponge helps in the recycling of the same. The use of aerogel in the aerospace, electronics, healthcare, and oil &gas industries. The main advantages of aerogel are that its cost of production is very high and the mechanical strength is also very poor. The most common aerogel is the silica aerogel. Important usage of silica aerogel in industries like automotive, oil & gas, aerospace, electronics, building insulation and many more. The increase in demand for biodegradable products is witnessed owing to the rising cognizance in respect of protection for environment. The attribute of aerogel of having low thermal circulation makes it an effective alternative for conventional insulators. As a result, its cost and energy both are reduced.

The market of aerogel is developing due to its widespread application in many industries which resulted in many technological developments in the market. Though, aerogel causes irritation in skin, eyes, respiratory tract, and digestive system. Silicosis occurs when particles of silica is inhaled which causes skin and eye dehydration. So, during handling of aerogel, protective gear should be worn which include glove, eye goggles and also respiratory protection should also be undertaken.

The main companies of the market of aerogel include Aspen Aerogels Inc. (U.S.), Cabot Corporation (U.S.), Aerogel Technologies LLC (U.S.), Nano High-Tech Co. Ltd. (China), Guangdong Alison Hi-Tech Co. Ltd. (China), Active Aerogels (Portugal), Enersens SAS (France), JIOS Aerogel Corporation (South Korea), and BASF SE (Germany).

what's your favourite cube in your cube collection?

awUAH FUCK this is such a difficult question. they all serve their own specific purpose so well. like, the colour one has the pretty colours, and the puzzle one gives me 3-for-1 puzzles, and the photos one lets me look at my dog and brother in my desk, and the trisected one splits up all cool like, and the minecraft diamond one is minecraft, and the flashy light up mirrors one lets me gaze upon infinity on a whim and ponder its secrets and also is a good night light ^^

just. yeah! they all perfectly serve their own unique functions! alas, i cannot choose

I’m AMAB and gay so it’s not my area of expertise but is 99 lbs even realistic for a woman jack-o’s size? That’s so crazy to me even as a scrawny teen I don’t ever remember being lighter than 140 n I feel like jack-o should have a decent bit of muscle and fat on her but maybe that’s my optimism

No haha Absolutely not and definitely not for how much thicker she is in Strive compared to Xrd too. The weights in GG are hilarious, like I think Sol's height/weight is 6' and 190lbs? There's not a chance in hell that wall of meat weighs anything less than 230 lol

Jack-O', realistically, would probably be more in the 130-150 range depending on how much muscle she has but GG has a slight girls with muscle allergy so who knows. 99lbs is ridiculous either way though rofl
