Is it COVID-19 or the flu? New sensor could tell you in 10 seconds      (via sciencedaily.com) 

Have a cough, sore throat and congestion? Any number of respiratory viruses could be responsible. Today, scientists report using a single-atom-thick nanomaterial to build a device that can simultaneously detect the presence of the viruses that cause COVID-19 and the flu -- at much lower levels and much more quickly than conventional tests for either.

Probe where the protons go to develop better fuel cells      (via sciencedaily.com)     Original source 

Researchers have uncovered the chemical inner-workings of an electrolyte they developed for a new generation of solid oxide fuel cells. To uncover the location of the proton-introduction reaction, the team studied extensively the hydration reaction of their scandium-substituted barium zirconate perovskite through a combination of synchrotron radiation analysis, large-scale simulations, machine learning, and thermogravimetric analysis. The new data has the potential to accelerate the development of more efficient fuel cells.

Advanced electrode to help remediation of stubborn new 'forever chemicals'      (via sciencedaily.com) 

As new environmental regulations are rolling out to mitigate the industry-retired long-chain chemicals known as PFAS in drinking water, there are concerns regarding a new breed of 'forever chemicals' called short-chain PFAS. Research is now helping shift the focus to include mitigation of the chemicals -- which researchers say are just as persistent as, more mobile and harder to remove from the environment than their long-chain counterparts.

What do the elements sound like?      (via sciencedaily.com) 

In chemistry, we have He, Fe and Ca -- but what about do, re and mi? Using a technique called data sonification, a recent college graduate has converted the visible light given off by each of the elements into soundwaves. The notes produced for each element are unique, complex mixtures and are the first step toward an interactive, musical periodic table.

Looking from different perspectives! Proper electronic structure of near-infrared absorbing functional dyes discovered      (via sciencedaily.com) 

A research group has discovered that near-infrared absorbing dyes, which had previously been considered to have closed-shell electronic structures, have an intermediate electronic structure, between closed- and open-shell structures. They also found that as the wavelength of near-infrared light that can be absorbed becomes longer the contribution of open-shell forms increases within the dye. These newly discovered characteristics are expected to be utilized to develop new near-infrared absorbing dyes that can absorb longer wavelength near-infrared light.

New type of entanglement lets scientists 'see' inside nuclei      (via sciencedaily.com) 

Nuclear physicists have found a new way to see inside nuclei by tracking interactions between particles of light and gluons. The method relies on harnessing a new type of quantum interference between two dissimilar particles. Tracking how these entangled particles emerge from the interactions lets scientists map out the arrangement of gluons. This approach is unusual for making use of entanglement between dissimilar particles -- something rare in quantum studies.

Closed loop for circular economy: New polymer recycling strategy ensures both high stability and complete recyclability      (via sciencedaily.com) 

Large amounts of plastic waste are incinerated or deposited in landfills. This degrades the environment and depletes valuable resources. In this light, recycling plastics such as polymers is promising. However, recycling diminishes their quality. Recently, researchers have proposed a 'closed-loop' recycling process based on polymer microparticles. It produces fully recyclable polymer films with high mechanical stability and fracture energy, which they retain upon recycling.

Robot caterpillar demonstrates new approach to locomotion for soft robotics      (via sciencedaily.com) 

Researchers have demonstrated a caterpillar-like soft robot that can move forward, backward and dip under narrow spaces. The caterpillar-bot's movement is driven by a novel pattern of silver nanowires that use heat to control the way the robot bends, allowing users to steer the robot in either direction.
