Greener air-conditioning for a warmer world

Jul 28, 2022 (Nanowerk News) When the heat of summer hits, air conditioners turn on and energy demand skyrockets, straining the grid. In a warmer world, more efficient cooling options will play an important role in curbing the increase of cooling-related energy demands. This will be particularly true for the...

Reducing food waste with novel biomaterials technologies

Jul 28, 2022 (Nanowerk Spotlight) Food waste reduction offers multi-faceted wins for people and planet, improving food security, addressing climate change, saving money and reducing pressures on land, water, biodiversity and waste management systems. Consider the staggering scale of the problem: Data gathered by the FAO, the Food and Agriculture...

A nanokelvin microwave freezer for molecules

Jul 28, 2022 (Nanowerk News) Researchers at Max Planck Institute of Quantum Optics (MPQ) have developed a novel cooling technique for molecular gases. It makes it possible to cool polar molecules down to a few nanokelvin ("Evaporation of microwave-shielded polar molecules to quantum degeneracy"). The trick used by the team...

Intracellular nanothermometer has unprecedented versatility

Jul 28, 2022 (Nanowerk News) Everyone has their temperature measured at a physician's office as a basic indicator of health. Intracellular temperature is also a basic indicator of cellular health; cancer cells are more metabolically active—and thus can have a slightly higher temperature—than healthy cells. However, until now the available...

Nanodiamonds are a cell’s best friend

Jul 27, 2022 (Nanowerk News) Nanodiamonds' repertoire of applications expands constantly, including everything from ultra-fine coatings to precise drug delivery. Now, Kyoto University and Daicel Corporation have developed nanodiamonds to detect temperatures on the nanoscale inside cells and organelles (Carbon, "All-optical nanoscale thermometry based on silicon-vacancy centers in detonation nanodiamonds")....

Researchers give 2D electronics a performance boost

Jul 27, 2022 (Nanowerk News) Two dimensional (2D) semiconductors have a unique property that allows their thickness to be reduced to one or few atoms – and this property could potentially minimise the short channel effects that remain an issue in advanced silicon-based transistors, for example, turning on a transistor...
