Published Electrons take flight at the nanoscale
(via sciencedaily.com) A study showing how electrons flow around sharp bends, such as those found in integrated circuits, has the potential to improve how these circuits, commonly used in electronic and optoelectronic devices, are designed.
Published New recipes for origin of life may point way to distant, inhabited planets
(via sciencedaily.com) Original source Life on a faraway planet -- if it's out there -- might not look anything like life on Earth. But there are only so many chemical ingredients in the universe's pantry, and only so many ways to mix them. Scientists have now exploited those limitations to write a cookbook of hundreds of chemical recipes with the potential to give rise to life. Their ingredient list could focus the search for life elsewhere in the universe by pointing out the most likely conditions -- planetary versions of mixing techniques, oven temperatures and baking times -- for the recipes to come together.
Published Machine learning models can produce reliable results even with limited training data
(via sciencedaily.com) Researchers have determined how to build reliable machine learning models that can understand complex equations in real-world situations while using far less training data than is normally expected.
Published Precisely arranging nanoparticles
(via sciencedaily.com) In the incredibly small world of molecules, the elementary building blocks -- the atoms -- join together in a very regular pattern. In contrast, in the macroscopic world with its larger particles, there is much greater disorder when particles connect. A research team has now succeeded in achieving the same precise arrangement of atoms shown in molecules, but using nanometer-sized particles, known as 'plasmonic molecules' -- combinations of nanoscale metallic structures that have unique properties.
Published Novel ligands for transition-metal catalysis of photoreactions
(via sciencedaily.com) Transition metals exchange electrons with supporting ligands to form complexes that facilitate reaction catalysis in several industries, like pharmaceutical production. Both the metal center and the ligand moiety have pivotal roles in enabling catalysis. While numerous transition metal-catalyzed photoreactions have been developed, only a few new ligands have been reported. Researchers from Chiba University have now developed novel ligands to create transition metal complexes, defining new reaction capabilities.
Published Engineers grow full wafers of high-performing 2D semiconductor that integrates with state-of-the-art chips
(via sciencedaily.com) Researchers have grown a high-performing 2D semiconductor to a full-size, industrial-scale wafer. In addition, the semiconductor material, indium selenide (InSe), can be deposited at temperatures low enough to integrate with a silicon chip.
Published Step change in upconversion the key to clean water, green energy and futuristic medicine
(via sciencedaily.com) Achieving photochemical upconversion in a solid state is a step closer to reality, thanks to a new technique that could unlock vital innovations in renewable energy, water purification and advanced healthcare.
Published New clues to the nature of elusive dark matter
(via sciencedaily.com) A team of international researchers has uncovered further clues in the quest for insights into the nature of dark matter. The key to understanding this mystery could lie with the dark photon, a theoretical massive particle that may serve as a portal between the dark sector of particles and regular matter.
Published Golden future for thermoelectrics
(via sciencedaily.com) Researchers discover excellent thermoelectric properties of nickel-gold alloys. These can be used to efficiently convert heat into electrical energy.
Published Groundbreaking research shows that the limits of nuclear stability change in stellar environments where temperatures reach billions of degrees Celsius
(via sciencedaily.com) Original source New research is challenging the scientific status quo on the limits of the nuclear chart in hot stellar environments where temperatures reach billions of degrees Celsius.
Published Carbon atoms coming together in space
(via sciencedaily.com) Original source Lab-based studies reveal how carbon atoms diffuse on the surface of interstellar ice grains to form complex organic compounds, crucial to reveal the chemical complexity in the universe.
Published Making hydrogen from waste plastic could pay for itself
(via sciencedaily.com) Researchers have found a way to harvest hydrogen from plastic waste using a low-emissions method that generates graphene as a by-product, which could help offset production costs.
Published Scientists invent a bright way to upcycle plastics into liquids that can store hydrogen energy
(via sciencedaily.com) Scientists have created a process that can upcycle most plastics into chemicals useful for energy storage, using light-emitting diodes (LEDs) and a commercially available catalyst, all at room temperature. The new process is very energy-efficient and can be easily powered by renewable energy in the future, unlike other heat-driven recycling processes like pyrolysis. Currently, only nine per cent of plastics globally are recycled and the rest are typically discarded in landfills or incinerated.
Published Pixel-by-pixel analysis yields insights into lithium-ion batteries
(via sciencedaily.com) By mining X-ray images, researchers have made significant new discoveries about the reactivity of lithium iron phosphate, a material used in batteries for electric cars and in other rechargeable batteries.
