Detecting trace amounts of multiple classes of antibiotics in foods

Widespread use of antibiotics in human healthcare and livestock husbandry has led to trace amounts of the drugs ending up in food products. Long-term consumption could cause health problems, but it’s been difficult to analyze more than a few antibiotics at a time because they have different chemical properties. Now, researchers reporting in ACS’ Journal […]

Researchers use nanomaterials to make 2D diamond clusters at room temperature

BROOKLYN, New York, Monday, January 26, 2021 – Atomically thin, 2D hexagonal boron nitride (h-BN) is a promising material whose protean ability to undergo phase transformations to strong, super lightweight, chemically stable, oxidation-resistant films makes them ideal for protective coatings, nanotechnology thermal applications, deep-UV light emitters, and much more. The possibilities embodied in different polytypes […]

New technique builds super-hard metals from nanoparticles

An anode-free zinc battery that could someday store renewable energy

Renewable energy sources, such as wind and solar power, could help decrease the world’s reliance on fossil fuels. But first, power companies need a safe, cost-effective way to store the energy for later use. Massive lithium-ion batteries can do the job, but they suffer from safety issues and limited lithium availability. Now, researchers reporting in […]

Scientists synthetize new material for high-performance supercapacitors

Scientists of Tomsk Polytechnic University jointly with colleagues from the University of Lille (Lille, France) synthetized a new material based on reduced graphene oxide (rGO) for supercapacitors, energy storage devices. The rGO modification method with the use of organic molecules, derivatives of hypervalent iodine, allowed obtaining a material that stores 1.7 times more electrical energy. […]
