| Surprising semiconductor properties revealed with innovative new method Posted: 01 Mar 2022 06:36 AM PST Semiconductor experiments reveal a surprising new source of conductivity from oxygen atoms trapped inside the material. |
| New optical tweezers put on the pressure to change color Posted: 28 Feb 2022 02:20 PM PST Scientists demonstrate an optical trapping technique using nanotextured black silicon that can efficiently trap polymer chains. By adjusting the laser intensity, these 'optical tweezers' can control the florescence color emitted through a local concentration of a perylene-modified polymer solution. From a low intensity blue to high intensity orange, this reversible and fully remote technology can almost reach the entire RGB spectrum. |
| New screening system may point the way to clean, renewable hydrogen power Posted: 28 Feb 2022 02:20 PM PST A new, highly sensitive system for detecting the production of hydrogen gas may play an important role in the quest to develop hydrogen as an environmentally friendly and economical alternative to fossil fuels. |
| Researchers establish first-of-its-kind framework to diagnose 3D-printing errors Posted: 28 Feb 2022 02:20 PM PST Additive manufacturing, or 3D printing, can create custom parts for electromagnetic devices on-demand and at a low cost. These devices are highly sensitive, and each component requires precise fabrication. Until recently, though, the only way to diagnose printing errors was to make, measure and test a device or to use in-line simulation, both of which are computationally expensive and inefficient. |
| Scaling laws in enzymes may help predict life ‘as we don’t know it' Posted: 28 Feb 2022 01:16 PM PST A team of researchers is developing tools to predict the features of life as we don't know it. |
| Physicists bring a once-theoretical effect of quantum matter into observable reality Posted: 28 Feb 2022 12:06 PM PST Physicists have experimentally observed a quirky behavior of the quantum world: a 'quantum boomerang' effect that occurs when particles in a disordered system are kicked out of their locations. Instead of landing elsewhere as one might expect, they turn around and come back to where they started and stop there. |
| Under pressure: A new theory lets us predict when soft materials will fail Posted: 28 Feb 2022 12:06 PM PST Researchers recently announced a major theoretical and experimental breakthrough that allows scientists to predict, with an unprecedented precision, when a soft material will crack and fail. The findings have immediate implications for the engineering and manufacture of a wide range of polymers. They also provide insights into how natural soft materials -- such as the connective tissues in our bodies and even our brains -- break down. |
| Clues to better batteries emerge from tracking lithium Posted: 28 Feb 2022 09:56 AM PST A new study tracked lithium metal deposition and removal from a battery anode while it was cycling to find clues as to how failure occurs. The research could help improve the use of pure lithium metal in anodes for electric vehicle batteries, which would reduce battery weights and dramatically extend driving range. |
| Spintronics: Innovative crystals for future computer electronics Posted: 28 Feb 2022 08:43 AM PST Computer chips and storage elements are expected to function as quickly as possible and be energy-saving at the same time. Innovative spintronic modules are at an advantage here thanks to their high speed and efficiency, as there is no lossy electrical current, rather the electrons couple with one another magnetically -- like a series of tiny magnetic needles which interact with almost no friction loss. A team of scientists has now found promising properties with crystals grown from rare-earth atoms, which offer hope on the long path towards usage as spintronic components. |
| Posted: 28 Feb 2022 08:43 AM PST Hydrogels have an astonishing ability to swell and take on water. In daily life, they are used in dressings, nappies, and more to lock moisture away. A team of researchers has now found another use: quickly extracting large amounts of freshwater from air using a specially developed hydrogel containing a hygroscopic salt. The study shows that the salt enhances the moisture uptake of the gel, making it suitable for water harvesting in dry regions. |
| New, nature-inspired concepts for turning CO2 into clean fuels Posted: 28 Feb 2022 08:43 AM PST Researchers have developed an efficient concept to turn carbon dioxide into clean, sustainable fuels, without any unwanted by-products or waste. |
| New data analysis tool uncovers important COVID-19 clues Posted: 28 Feb 2022 08:43 AM PST A new data analysis tool has revealed the specific immune cell types associated with increased risk of death from COVID-19. |
| Separator key when it comes to 'stable' vs. 'safe' battery Posted: 28 Feb 2022 07:38 AM PST Researchers have discovered the key to making a stable, safe battery. |
| Computer drug simulations offer warning about promising diabetes and cancer treatment Posted: 28 Feb 2022 06:11 AM PST Using computer drug simulations, researchers have found that doctors need to be wary of prescribing a promising treatment for all types of cancer and patients. |
| A potential breakthrough for production of superior battery technology Posted: 28 Feb 2022 06:11 AM PST Micro supercapacitors could revolutionize the way we use batteries by increasing their lifespan and enabling extremely fast charging. Manufacturers of everything from smartphones to electric cars are therefore investing heavily into research and development of these electronic components. Now, researchers have developed a method that represents a breakthrough for how such supercapacitors can be produced. |
| Posted: 28 Feb 2022 06:11 AM PST Researchers have developed and tested a new imaging approach they say will accelerate imaging-based research in the lab by allowing investigators to capture images of blood vessels at different spatial scales. |
| Posted: 25 Feb 2022 01:33 PM PST Researchers detail a breakthrough discovery in nanomaterials and light-wave interactions that paves the way for development of small, low-energy optical computers capable of advanced computing. |
