| Molecular bridges power up printed electronics Posted: 25 Feb 2021 08:31 AM PST Researchers have boosted the efficiency of conductive inks and devices connecting layered materials flakes with small molecules. |
| On the line: Watching nanoparticles get in shape Posted: 25 Feb 2021 05:25 AM PST Scientists have captured real-time, high-resolution videos of liquid structures taking shape as nanoparticles form a solid-like layer at the interface between oil and water. Their findings could help advance all-liquid robotics for targeted cancer drug delivery and other applications. |
| 'Miracle poison' for novel therapeutics Posted: 25 Feb 2021 05:25 AM PST Researchers demonstrate they can engineer botulinum toxin proteins (called proteases) to find new targets with high selectivity, a critical advance toward potential new treatments for everything from neuroregeneration to cytokine storm. |
| New shape-changing 4D materials hold promise for morphodynamic tissue engineering Posted: 25 Feb 2021 05:24 AM PST New hydrogel-based materials that can change shape in response to psychological stimuli, such as water, could be the next generation of materials used to bioengineer tissues and organs, according to a team of researchers. |
| Pushing computing to the edge by rethinking microchips' design Posted: 24 Feb 2021 11:36 AM PST Responding to artificial intelligence's exploding demands on computer networks, researchers in recent years have radically increased the speed and slashed the energy use of specialized AI systems. Now, the researchers have moved their innovation closer to widespread use by creating co-designed hardware and software that will allow designers to blend these new types of systems into their applications. |
| Nature's funhouse mirror: Understanding asymmetry in the proton Posted: 24 Feb 2021 11:34 AM PST The results of a new experiment could shift research of the proton by reviving previously discarded theories of its inner workings. |
| Twin atoms: A source for entangled particles Posted: 24 Feb 2021 11:34 AM PST One of the most important phenomena in quantum physics is entanglement - used for quantum krypography, quantum computers and many other applications. While it is easy to create pairs of entangled photons, it is much harder to create entangled atoms in a well-defined way. This has now been made possible using an experimental setup. |
| Most important global supply chain linkages Posted: 24 Feb 2021 06:07 AM PST In today's global economy, production of goods depends on inputs from many trade partners around the world. Companies and governments need a deeper understanding of the global value chain to reduce costs, maintain a profitable production system, and anticipate ripple effects of disruptions in the supply chain. |
| Jumping frost crystals: Lab works toward electrostatic de-icing Posted: 24 Feb 2021 06:06 AM PST Boreyko's team is working toward removing large sheets of ice by increasing the amount of charge that comes near the frost. |
| Treating rheumatoid arthritis with micromotors Posted: 24 Feb 2021 06:06 AM PST Rheumatoid arthritis is a chronic inflammatory disorder marked by joint pain, swelling and damage. Although medications, such as steroids, anti-inflammatory drugs and immunosuppressants, can help slow joint destruction and relieve pain, they have side effects and aren't completely successful. Now, researchers have developed magnesium-based micromotors propelled by hydrogen bubbles, which improved rheumatoid arthritis symptoms when injected into the joints of rats. |
| Positive reinforcements help algorithm forecast underground natural reserves Posted: 23 Feb 2021 01:44 PM PST Researchers have designed a reinforcement-based algorithm that automates the process of predicting the properties of the underground environment, facilitating the accurate forecasting of oil and gas reserves. |
| Oxidation processes in combustion engines and in the atmosphere take the same routes Posted: 23 Feb 2021 01:44 PM PST Alkanes, an important component of fuels for combustion engines and an important class of urban trace gases, react via another reaction pathways than previously thought. These hydrocarbons, formerly called paraffins, thus produce large amounts of highly oxygenated compounds that can contribute to organic aerosol and thus to air pollution in cities. The results of this interdisciplinary work provide crucial information about oxidation processes both in combustion engines and in the atmosphere. |
| Machine learning aids in simulating dynamics of interacting atoms Posted: 23 Feb 2021 01:44 PM PST A revolutionary machine-learning (ML) approach to simulate the motions of atoms in materials such as aluminum is described. |
| Biopolymer-coated nanocatalyst can help realize a hydrogen fuel-driven future Posted: 23 Feb 2021 09:16 AM PST While popular as an eco-friendly fuel, hydrogen is difficult to produce efficiently in an eco-friendly manner (through sunlight-induced decomposition of water) due to stability issues of catalysts (chemical reaction facilitators). In a new study, scientists demonstrate water splitting under sunlight using polydopamine-coated zinc sulfide nanorods as a catalyst. In their paper, they report a remarkably enhanced hydrogen production rate and look into the causes, paving the way for a hydrogen-based future. |
