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.

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

craving aerogel rn :((((((

[solradguy]

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

Research Seeks to Break the Mold of Ultra-Lightweight Aerogels - Technology Org

Research Seeks to Break the Mold of Ultra-Lightweight Aerogels - Technology Org

Producing ultra-lightweight materials that are also strong could revolutionize multiple industries. With groundbreaking work from an interdisciplinary team of chemists and 3D printing experts, that revolution could be closer.

Aerogels are a unique class of ultra-low-density materials with a weight only about 15 times heavier than air. If an average adult were made of aerogel, they would weigh somewhere between 3 and 14 pounds.

The material has been around for a little less than 100 years, and the first aerogels were a highly porous solid containing more than 99 percent air, nicknamed “frozen smoke.” Although these aerogels made from silica glass have achieved the Guinness World Record for the lowest density solids, they are known to be very brittle and quite expensive to process. 

Today, the race is on to find new materials and cost-effective methods to produce incredibly strong aerogels for advanced applications such as thermal insulation for aerospace vehicles, passive solar insulation for next generation housing, water and air filtration, lightweight packaging, controlled drug delivery, and personally tailored biomedical scaffolding.

That race has some strong Virginia Tech contenders. Robert Moore, a professor in the Department of Chemistry in the College of Science, has joined forces with Christopher Williams, the LS Randolph Professor of Mechanical Engineering in the College of Engineering. They have brought together the resources of both their groups to produce new approaches to engineered aerogels, channeled through the Macromolecules Innovation Institute. Graduate researchers Garrett F. Godshall and Daniel A. Rau have led those teams with innovations in both materials and machinery with the methods published in the journal Advanced Materials.

Strong, lightweight skeletons

The first step to making an aerogel involves producing a gel, a 3D solid network that entraps a liquid, like water in gelatin. The next step involves carefully removing the liquid in the gel, leaving behind an ultralight microporous sponge-like skeleton because the heavy liquid has been replaced by air and is potentially strong because of its interconnected 3D lattice.  

One material that had not previously been developed as an aerogel is polyphenylene sulfide (PPS), a super strong thermoplastic often used as a substitute for metal when weight reduction and chemical resistance is required. As an aerogel, PPS could usher in a new wave of applications, particularly in lightweight high performance thermal insulation. Recently, Moore’s research group has demonstrated a simple process for creating PPS gels and aerogels using a unique nontoxic, environmentally friendly solvent. 

Moore’s team brought its process to Williams, who has pioneered novel 3D printing methods.  

“Bob and I have been working together for many years thanks to the interdisciplinarity fostered through the Macromolecules Innovation Institute,” said Williams. “We hosted a joint meeting between our two groups over a summer so that our students could become more aware of our labs’ capabilities and expertise and ideate ways we could collaborate. From that meeting, we identified that Bob’s novel approach for synthesizing PPS aerogels would meld well with my group’s expertise in 3D printing and prior work in printing PPS.”

“Unlike the silica aerogels or other crosslinked polymers used by NASA, our PPS gels don’t require complex chemical reactions and they can be melted and solidified over and over again,” said Moore. “All we have to do is make a hot solution of commercially available PPS and then cool it to room temperature. Using our new, safe solvent, which is actually an FDA-approved food grade additive, the PPS solutions gel in seconds. It is as simple as making Jell-O. But once we saw the super-fast solidification of these gels, we knew it was time to team up with the Williams group to see if we could print this stuff.”

The PPS aerogel barrier has been breached with Moore’s discovery of rapid PPS gelation. Using a combination of simple chemistry and 3D printing innovation, the first additive manufacturing of PPS into an aerogel is now a reality. 

Breaking the mold

Like gelatin, the gels that are used to make aerogels are conventionally formed in open molds. This yields a solid form with limited size and shape. Making PPS aerogels with engineered shapes and geometries requires a combination of innovations in polymer chemistry and advanced manufacturing. 

On Moore’s team, Godshall produced pellets of the PPS gel and placed them into a new, high temperature printing tool designed by Rau specifically for this task. Inside the nozzle, the gel pellets are re-liquified and extruded onto a substrate, where they cool and re-solidify.

After the print is finished, the solvent-containing gel part has the solvent removed through an exchange process and freeze drying, resulting in a PPS aerogel. This process enables the formation of microscopic pores that can be tuned by the print settings. Moreover, at the macroscale, the three-dimensional form of the PPS aerogel can be tailored by the infinite shape possibilities of 3D printing. 

Creating large, lightweight shapes to the contour of an airplane wing or small insulating structures incorporated in electronic devices means a reduction of materials in manufacturing; strong aerogel frameworks could equate to a reduction of fuel with lighter vehicles, and engineered thermal insulators could advance energy efficiency in next-generation technologies.

“This publication represents a significant breakthrough in the manufacturing of complex aerogels from engineering polymers,” said Williams. “Bob’s synthesis technique can work for a number of other high-performance polymers, and the printing process can be easily modified to account for these changes. We were surprised to learn that the processing conditions have an effect over the morphology and density of the aerogel structure. We are excited to study this further and discover how to gain control and program this structure and performance into new multi-functional parts.”

everything does feel smooth and lifted on air again but its so fragile... interrupted... if i step just right i can stay on top of the ice but its easy to fall into a crack and its hard to get out. i prefer the smoothness but its the contrast that kills.

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.
