Scientists create rechargeable swimming microrobots using oil and water

By combining oil drops with water containing a detergent-like substance, the scientists found they could produce artificial swimmers that are able to swim independently and even harvest energy to recharge. The oil droplets use fluctuating temperature changes in their surrounding…

Chemical reactions break free from energy barriers using flyby trajectories

CHAMPAIGN, Ill. — A new study shows that it is possible to use mechanical force to deliberately alter chemical reactions and increase chemical selectivity – a grand challenge of the field. The study led by University of Illinois Urbana-Champaign researcher…

Removing the lead hazard from perovskite solar cells

“The solar energy-to-electricity conversion of perovskite solar cells is unbelievably high, around 25%, which is now approaching the performance of the best silicon solar cells,” says Professor László Forró at EPFL’s School of Basic Sciences. “But their central element is…

Sweet spot for membrane thickness offers sustainable separations

Super-thin carbon molecular sieve (CMS) membranes may not be best for separating industrially important chemical mixtures. However, ensuring the CMS film thickness is just right could enable more energy-efficient purification of chemical products, KAUST researchers have shown. CMS membranes, as…

New spray could someday help heal damage after a heart attack

Heart attack, or myocardial infarction, is one of the leading causes of death worldwide. Although modern surgical techniques, diagnostics and medications have greatly improved early survival from these events, many patients struggle with the long-term effects of permanently damaged tissue,…

Hydrogel composite developed to help protective gear rapidly degrade toxic nerve agents

Scientists at Northwestern University in Evanston, Illinois have developed a hydrogel integrated with zirconium-based robust metal-organic frameworks (MOFs) that rapidly degrades organophosphate-based nerve agents used in chemical warfare. Unlike existing powdered MOF adsorbents, this hydrogel composite does not require added…

Putting a strain on semiconductors for next-gen chips

Skoltech researchers and their colleagues from the U.S. and Singapore have created a neural network that can help tweak semiconductor crystals in a controlled fashion to achieve superior properties for electronics. This enables a new direction of development of next-generation…

Microcrystal electron diffraction supports a new drug development pipeline

CAMBRIDGE July 13, 2021 – To date, solving structures of potential therapeutics using X-ray diffraction (XRD) has been an assumed, pivotal step in the drug development process. But a recent paper by a team of researchers led by NanoImaging Services…

Mosquito-resistant clothing prevents bites in trials

North Carolina State University researchers have created insecticide-free, mosquito-resistant clothing using textile materials they confirmed to be bite-proof in experiments with live mosquitoes. They developed the materials using a computational model of their own design, which describes the biting behavior…

New study provides a solution for engineering cellular materials

A new study by a Swansea University academic has announced a new mathematical formula that will help engineers assess the point at which cellular materials, which are used a wide range of applications ranging from aerospace to the construction industry,…
