| A new, nanoscale, 3D structure to control light Posted: 02 Feb 2022 01:27 PM PST Metamaterials, made up of small, repeated structures, engineered to produce desired interactions with light or sound waves, can improve optical devices used in telecommunications, imaging and more. But the functionality of the devices can be limited by the corresponding design space. |
| Scientists develop 'exceptional' surface to explore exotic physics Posted: 02 Feb 2022 12:38 PM PST By demonstrating exceptional control of an open optical system, an international research team has provided a path to experimentally measure and test exotic phenomena and gain insights into new physics with exquisite sensitivity. |
| Researchers set record by preserving quantum states for more than 5 seconds Posted: 02 Feb 2022 12:38 PM PST A team of researchers has maintained a qubit coherence time for a record five seconds. The qubits are made from silicon carbide, widely found in lightbulbs, electric vehicles and high voltage electronics. |
| Quick COVID breathalyzer could allow mass screening in public places Posted: 02 Feb 2022 11:31 AM PST Researchers have developed a prototype 'breathalyzer' that can sensitively and accurately diagnose COVID-19, even in asymptomatic individuals, in less than 5 minutes. |
| Scientists develop insect-sized flying robots with flapping wings Posted: 02 Feb 2022 11:30 AM PST A new drive system for flapping wing autonomous robots has been developed, using a new method of electromechanical zipping that does away with the need for conventional motors and gears. |
| Engineers develop surgical 'duct tape' as an alternative to sutures Posted: 02 Feb 2022 11:30 AM PST Engineers have developed a kind of surgical 'duct tape.' The strong, flexible, and biocompatible sticky patch can be applied to biological tissues and organs to help seal tears and wounds. |
| Novel method simulates tens of thousands of bubbles in foamy flows Posted: 02 Feb 2022 11:30 AM PST Bubbles aren't just for bath time. Bubbles, specifically bubbles in foamy flows, are critical for many industrial processes, including the production of food and cosmetics and drug development and delivery. But the behavior of these foamy flows is notoriously difficult to compute because of the sheer number of bubbles involved. Previous attempts to simulate foamy flows have relied on the time-consuming and computationally expensive process of tracking the bubbles by color-coating each individual bubble in the foam. This limited simulations to just a few dozen bubbles, instead of the thousands to millions in real foams. Now, researchers have developed a new way to simulate tens of thousands of bubbles in foamy flows, breaking the computational complexity of this long-standing process. |
| Testing the effectiveness of KN95 and surgical mask 'fit hacks' Posted: 02 Feb 2022 11:30 AM PST Researchers have tested a variety of popular hacks for improving the fit of KN95 and surgical masks, and found that while some hacks do improve fit, they can also come at the cost of the wearer's comfort. |
| Scientists engineer new material that can absorb and release enormous amounts of energy Posted: 02 Feb 2022 10:47 AM PST A team of researchers recently announced that they had engineered a new rubber-like solid substance that has surprising qualities. It can absorb and release very large quantities of energy. And it is programmable. Taken together, this new material holds great promise for a very wide array of applications, from enabling robots to have more power without using additional energy, to new helmets and protective materials that can dissipate energy much more quickly. |
| Novel chemical glucose sensing method based on boronic acids and graphene foam Posted: 02 Feb 2022 10:47 AM PST Researchers have developed a new glucose sensor that is cheaper and more robust than current systems. |
| Simple, inexpensive, fast and accurate nano-sensors pinpoint infectious diseases Posted: 02 Feb 2022 08:18 AM PST Researchers describe a novel method for detecting viruses like Ebola virus (EBOV) and SARS CoV-2. |
| Cooling matter from a distance Posted: 02 Feb 2022 08:18 AM PST Researchers have succeeded in forming a control loop consisting of two quantum systems separated by a distance of one meter. Within this loop, one quantum system -- a vibrating membrane -- is cooled by the other -- a cloud of atoms, and the two systems are coupled to one another by laser light. Interfaces such as this allow different kinds of quantum systems to interact with one another even over relatively large distances and will play a key role in quantum technologies of the future. |
| Reassessing radon as a reliable groundwater tracer Posted: 02 Feb 2022 08:18 AM PST As radioactive atoms are transported through groundwater aquifers in the form of gaseous radon, they are eventually transferred to the atmosphere. Measurements of the rate of this transfer can, in theory, be used to trace the infiltration of water into the surrounding soil. Yet a new study shows that this technique could have a significant flaw. |
