Laser-patterned thin films that swell into kirigami-like structures offer new opportunities in hydrogel technology

New options for making finely structured soft, flexible and expandable materials called hydrogels have been developed by researchers at Tokyo University of Agriculture and Technology (TUAT). Their work extends the emerging field of "kirigami hydrogels," in which patterns are cut into a thin film allowing it to later swell into complex hydrogel structures. The research is published in the journal Science and Technology of Advanced Materials. Hydrogels have a network of water-attracting (hydrophilic) molecules, allowing their structure to swell substantially when exposed to water that becomes incorporated within the molecular network. Researchers Daisuke Nakagawa and Itsuo Hanasaki worked with an initially dry film composed of nanofibers of cellulose, the natural material that forms much of the structure of plant cell walls.

What goes on inside planets like Neptune and Uranus? To find out, an international team headed by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), the University of Rostock and France’s École Polytechnique conducted a novel experiment. They fired a laser at a thin film of simple PET plastic and investigated what happened using intensive laser flashes. One result was that the researchers were able to confirm their earlier thesis that it really does rain diamonds inside the ice giants at the periphery of our solar system. And another was that this method could establish a new way of producing nanodiamonds, which are needed, for example, for highly-sensitive quantum sensors. The group has presented its findings in the journal Science Advances.

Nanomaterials: Unveiling Their Science, Applications, and Implications

The realm of nanomaterials is a frontier of modern science, where the melding of physics and chemistry gives rise to materials with remarkable and often unprecedented properties. At the heart of this exploration are nanoscale materials, whose dimensions are measured in nanometers. These materials exhibit quantum effects that significantly alter their physical, chemical, and biological behaviors…

#klance fanart #klance #voltron legendary defender #ooofff you ever feel like you keep doing things and things are still to get done???#i keep saying this every five posts #i start to think loving getting in the 'art zone' is my biggest vice #because sure i sketch or do some digital work from time to time but if i haven't sat down to draw for hours #until eyes sting and neck cant move and brain sleepy af? is it drawing anymore? is it living anymore? yeah i thought so #im the main person making grocery shopping in this house did you know? for three people #there is always something running out and like let me tell you i already answer business emails while eating #i cleaned the windows today before my first coffee #okay to be fair i started it but apparently i used the wrong bottle and i smeared anti grease all over the windows #and then finished my coffee staring at the curvy roads of a thin film painted between me and the world promising myself to never do anythin #before first coffee #either way i feel like i havent been very present or entertaining lately #by which i mean on and off for months #am i correct or am i partially correct or reimagining things? who knows #but i keep having so many things i want to do it just keeps on going #i'm starting with commissions now #BUT THEN!!#haha yeah i hope you are having a great November and enjoy this piece!!#sending hugs <3 if you like them if not #a gentle wave from a far

David Bowie performing "TVC15" in 1976

#the colour correcting process on this was kind of wild #the og film seemed to have a cooler colour gamut or at least a bias toward blue #so i did my best to make them look closer to life #but its the best footage of the thin white duke that ive seen i had to make gifs #i made too many tbh considering its only about 1 or 2 mins of footage lol (also thank u danny for helping me choose the best of them!)#station to station #tvc15 #isolar i #david bowie #thin white duke #bowieposting #my gifs

Ultrablack thin-film coating could make next-gen telescopes even better

Sometimes, seeing clearly requires complete black. For astronomy and precision optics, coating devices in black paint can cut down on stray light, enhancing images and boosting performance. For the most advanced telescopes and optical systems, every little bit matters, so their manufacturers seek out the blackest blacks to coat them. In the Journal of Vacuum Science & Technology A, researchers from the University of Shanghai for Science and Technology and the Chinese Academy of Sciences developed an ultrablack thin-film coating for aerospace-grade magnesium alloys. Their coating absorbs 99.3% of light while being durable enough to survive in harsh conditions. For telescopes operating in the vacuum of space, or optical equipment in extreme environments, existing coatings are often insufficient.
