Chlorinated Cation Unlocks Durable Tin Perovskite Solar Cells in Open Air
6+ hour, 9+ min ago (489+ words) Tin halide perovskites have long been the tantalizing alternative to lead-based perovskites in next-generation solar cells. They offer a narrower bandgap that is ideal for harvesting more of the solar spectrum, and they replace toxic lead with an environmentally friendlier…...
One Atom Apart: Crystal Wiring Trick Pushes Perovskite Solar Cells Past 27
8+ hour, 44+ min ago (698+ words) Perovskite solar cells have spent more than a decade rewriting the record books, but the most valuable real estate in these devices has always been the interface, the razor-thin boundary where the light-absorbing perovskite layer meets the contacts that siphon…...
Radical Building Blocks Yield Porous Organic Semiconductors That Need No
13+ hour, 5+ min ago (628+ words) Semiconductors are the beating heart of modern technology, yet the organic varieties that promise flexible, lightweight and cheap alternatives to silicon have long been haunted by an inconvenient paradox. To conduct electricity, many organic frameworks need to be treated with…...
Crystallization Control Unlocks 30.1% Efficient All-Perovskite
1+ day, 8+ hour ago (726+ words) Perovskite solar cells have spent the past decade shattering one efficiency record after another, but the technology’s most ambitious configuration—stacking three perovskite absorbers on top of one another in a single monolithic device—has remained stubbornly out of reach....
A case has emerged in which a person survived for 9 months after receiving a kidney transplant from a pig.
6+ day, 23+ hour ago (79+ words) There have been several previous cases of transplanting genetically modified pig organs into humans, and in one kidney transplant case Genetically modified pig kidney keeps man alive for record nine months | Medical research | The Guardian What is 'Go First Dice,…...
Mass General Brigham Uses Pig Kidney Bridge to Human Transplant in Landmark Case
1+ week, 10+ hour ago (481+ words) 66-year-old patient lives 271 days without dialysis on gene-edited Yucatan pig kidney before receiving deceased donor organ A patient who received a pig kidney not only achieved the longest survival record to date after an animal kidney transplant, but also successfully…...
3D-printed chip vascularizes kidney organoids derived from human stem cells
1+ week, 1+ hour ago (81+ words) Kidney organoids grown from human stem cells have transformed how researchers study kidney development and disease, but they have always shared one stubborn flaw: they lack blood vessels. Now a team at Maastricht University in the Netherlands has unveiled a…...
Chemical fabrication of SnO2/Co3O4/Si photodetector for visible-infrared
1+ week, 1+ day ago (378+ words) Researchers in Iraq have fabricated a broadband photodetector that can sense light across both the visible and infrared parts of the spectrum using nothing more exotic than two inexpensive metal oxides and a silicon wafer. The device, described as an…...
Huge multiphoton exciton nonlinearities found in layered hybrid perovskites
1+ week, 1+ day ago (445+ words) In a development that could reshape the design of next-generation optical and optoelectronic devices, researchers have reported the observation of extraordinarily large, anomalous nonlinear optical responses driven by excitons and multiphoton absorption in layered hybrid perovskite semiconductors....
Fluorine doping tunes conductivity in oxyfluoride glasses
1+ week, 1+ day ago (831+ words) In the quiet pursuit of better batteries and supercapacitors, some of the most promising breakthroughs are happening not in exotic new compounds but in carefully tweaked versions of familiar materials. A research team from St....
