How to upcycle low-energy light: A new design for highly efficient conversion materials
To combine two low-energy photons into one high-energy photon efficiently, the energy must be able to hop freely, but not too quickly, between randomly oriented molecules of a solid. This Kobe University discovery provides a much-needed design guidel.....»»
Not so simple machines: Cracking the code for materials that can learn
It's easy to think that machine learning is a completely digital phenomenon, made possible by computers and algorithms that can mimic brain-like behaviors. But the first machines were analog and now, a small but growing body of research is showing th.....»»

Observing gain-induced group delay between multiphoton pulses generated in a spontaneous down-conversion source
Spontaneous parametric down-conversion (SPDC) and spontaneous four-wave mixing are powerful nonlinear optical processes that can produce multi-photon beams of light with unique quantum properties. These processes could be leveraged to create various.....»»
Less is more: Why an economical iridium catalyst works so well
Iridium-based catalysts are needed to produce hydrogen using water electrolysis. Now, a team at HZB has shown that the newly developed P2X catalyst, which requires only a quarter of the iridium, is as efficient and stable over time as the best commer.....»»
Shape-changing polymer resembles animal movements with temperature shifts
A team of scientists has created a new shape-changing polymer that could transform how future soft materials are constructed. Made using a material called a liquid crystalline elastomer (LCE), a soft rubber-like material that can be stimulated by ext.....»»
Gurman: Apple-designed 5G modem coming to 2025 iPhones will be worse than Qualcomm’s
Apple’s long-in-the-works project to build its own cellular modem is about to see the light of day. As multiple reports have indicated in the past, select 2025 iPhone models will carry the Apple 5G modem—but thanks to a new report, now we know it.....»»

Solving waste plastic processing with heat circulation: Researchers develop large-scale pyrolysis process
Dr. Byungwook Hwang's research team from the CCS Research Department at the Korea Institute of Energy Research (KIER) has successfully developed a process that applies the circulating fluidized bed technology, commonly used in coal-fired power plant.....»»
3D models help researchers understand the climate impact of eddies
Mesoscale eddies are ocean vortices less than 100 kilometers in diameter that are responsible for the localized "weather" of the oceans. Because of the large amount of mass and energy movement associated with these currents, mesoscale eddies play an.....»»
Experiments provide evidence that interaction of light with a hydrocarbon molecule produces strained molecular rings
When molecules interact with ultraviolet (UV) light, they can change shape quickly, producing strain—stress in a molecule's chemical structure due to an increase in the molecule's internal energy. These processes typically take just tens of picosec.....»»
