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 […]

Increasing ocean temperature threatens Greenland’s ice sheet — ScienceDaily

Scientists at the University of California, Irvine and NASA’s Jet Propulsion Laboratory have for the first time quantified how warming coastal waters are impacting individual glaciers in Greenland’s fjords. Their work is the subject of a study published recently in Science Advances. Working under the auspices of the Oceans Melting Greenland mission for the past […]

Lowering the combustion temperature for methane — ScienceDaily

Natural gas is the cleanest traditional fossil fuel source because it produces relatively low amounts of pollutants like carbon dioxide — a potent greenhouse gas and major contributor to climate change. But greenhouse gases and pollutants released by burning natural gas could be reduced even further with the help of advanced catalysts that help lower […]

Catalyst transforms plastic waste to valuable ingredients at low temperature

Credit: WANG Haochen The C-H bond is very important in organic chemistry. Chemical reactions related to the breaking and further synthesis of the C-H bond require high activation energy and poor selectivity. Therefore, it’s important to understand […]

Light-activated sensor delivers precision results at room temperature — ScienceDaily

Inspired by the surface of butterfly wings, researchers have developed a light-activated hydrogen sensor that produces ultra-precise results at room temperature. The technology can detect hydrogen leaks well before they pose safety risks and can measure tiny amounts of the gas on people’s breath, for diagnosing gut disorders. Commercial hydrogen sensors only work at temperatures […]

Diamonds created in minutes at room temperature

A new study finds diamonds can actually form at room temperature, under the right pressure. Image credit: Shutterstock Diamonds are highly coveted the world over, forming naturally in the Earth’s mantle under extreme temperature and pressure over billions of years. Now, a team of scientists from the Australian National University (ANU) and the Royal Melbourne […]

Low temperature, scalable manufacturing of flexible energy harvesters

A simple approach to create high performance thermoelectric materials, which would allow one to turn their body heat into electricity. Imagine mixing together a few solutions and creating a material that would allow one to turn their body heat into electricity. A simple approach to energy harvesting is within reach now that an interdisciplinary team […]
