| Could used beer yeast be the solution to heavy metal contamination in water? Posted: 13 Jun 2022 01:27 PM PDT A new study finds inactive yeast could be effective as an inexpensive, abundant, and simple material for removing lead contamination from drinking water supplies. The approach should be efficient and economic, even down to part-per-billion levels of contamination. |
| Bioengineering team develops a remote lab to teach enzyme kinetics Posted: 13 Jun 2022 11:32 AM PDT Researchers demonstrate the implementation of a remote laboratory activity to teach students about enzyme kinetics. |
| A better wig -- with chemistry Posted: 13 Jun 2022 11:32 AM PDT For some people, wigs are a fun and colorful fashion accessory, but for those with hair loss from alopecia or other conditions, they can provide a real sense of normalcy and boost self-confidence. Whether made from human or synthetic strands, however, most hairpieces lose their luster after being worn day after day. Now, researchers report a new way to make wigs more durable and long lasting. |
| Posted: 13 Jun 2022 11:07 AM PDT The production of chemical substances normally requires environmentally harmful solvents. After researchers had produced organic substances without harmful substances by heating them in hot water, they can now chalk up another success: Through hydrothermal synthesis, they succeeded in jointly forming and combining organic and inorganic substances in the same reaction vessel. Specifically: an inorganic solid that encloses organic dye molecules. When exposed to light, which is by and large the most environmentally friendly energy resource, the hybrid material functions like a catalyst, i.e., a photocatalyst. Since the photocatalyst is a solid, it can be used multiple times. |
| Closed-loop additive manufacturing fueled by upcycled plastic Posted: 13 Jun 2022 11:07 AM PDT Researchers have developed an upcycling approach that adds value to discarded plastics for reuse in additive manufacturing, or 3D printing. The readily adoptable, scalable method introduces a closed-loop strategy that could globally reduce plastic waste and cut carbon emissions tied to plastic production. |
| Rubbery camouflage skin exhibits smart and stretchy behaviors Posted: 13 Jun 2022 09:45 AM PDT The skin of cephalopods, such as octopuses, squids and cuttlefish, is stretchy and smart, contributing to these creatures' ability to sense and respond to their surroundings. Scientists have harnessed these properties to create an artificial skin that mimics both the elasticity and the neurologic functions of cephalopod skin, with potential applications for neurorobotics, skin prosthetics, artificial organs and more. |
| Designing protection suits for hard working bacteria Posted: 13 Jun 2022 08:20 AM PDT Bacteria can contribute to a more sustainable production of chemicals, so providing a good working environment for them is a good investment. Now researchers present a nano protection suit, developed for bacteria. |
| Researchers solve mystery surrounding dielectric properties of unique metal oxide Posted: 13 Jun 2022 08:20 AM PDT A research team has solved a longstanding mystery surrounding strontium titanate, a metal oxide semiconductor, providing insight for future research on the material and its applications to electronic devices and data storage. |
| Engineers build artificial intelligence chip Posted: 13 Jun 2022 08:20 AM PDT Engineers built a new artificial intelligence chip, with a view toward sustainable, modular electronics. The chip can be reconfigured, with layers that can be swapped out or stacked on, such as to add new sensors or updated processors. |
| Energy harvesting to power the Internet of Things Posted: 13 Jun 2022 08:19 AM PDT Scientists have used computer modelling to optimize the design of an electromagnetic energy harvester to power wireless sensor networks for the Internet of Things. |
| Oxide growth in additively manufactured metals examined in sCO2 environment Posted: 13 Jun 2022 08:19 AM PDT A new study examines the differences in oxide film growth on additively manufactured (AM) metals and wrought stainless steel in a supercritical carbon dioxide (sCO2) environment. |
| Good news on blocking a virus considered a global threat Posted: 13 Jun 2022 08:15 AM PDT Scientists have reported good news on the pandemic preparedness front: A cocktail of four manufactured antibodies is effective at neutralizing a virus from the Henipavirus family, a group of pathogens considered to be a global biosecurity threat. |
| Can they make graphite from coal? Researchers start by finding new carbon solid Posted: 10 Jun 2022 10:28 AM PDT As the world's appetite for carbon-based materials like graphite increases, researchers presented evidence this week for a new carbon solid they named 'amorphous graphite.' |
| Posted: 07 Jun 2022 12:24 PM PDT The work could spur the development of novel mechanisms for light manipulation and promises profound implications for technologies such as miniaturized and robust lasers, optical computers, and high-precision, light-based sensors. |
