Electron microscopes are used wherever particularly small details need to be imaged. But from a strictly physical point of view, every electron in a conventional electron microscope represents a missed opportunity: If all ...
Quantum dots are semiconductor crystals only a few nanometers in size. Their ability to produce bright, precisely tunable colors has made them promising materials for light-emitting diodes, displays, solar cells and other ...
A research team led by Yang Lu from the Department of Mechanical Engineering at the Faculty of Engineering, The University of Hong Kong (HKU), has uncovered the microscopic physical nature of ultralarge elasticity in covalent ...
Bubbles are round, and we know surface tension does that. But squeeze that gas-liquid boundary into a space only a few tens of nanometers wide—could other forces be at work?
The energy system of the future will require sustainable catalysts that, for example, enable the efficient production of green hydrogen. Materials consisting of mixtures of five chemical elements show great promise for enabling ...
Ethanol is an alcohol used in a vast number of industrial and household applications. When dehydrogenated—in this case, stripped of some of its hydrogen atoms—it yields another important compound: acetaldehyde, which is used ...
Nitrate contamination originating from agricultural runoff, industrial wastewater and municipal effluents is a growing global environmental problem. At the same time, ammonia has emerged as a key chemical feedstock and an ...
What happens inside a citrus tree long before leaves turn yellow, roots decline, and fruit quality suffers? Researchers from the University of Florida Citrus Research and Education Center—Diann S. Achor, Camila Ribeiro, Jinyun ...
Light Emitting Diodes (LEDs) are used in everything from household lighting and mobile phones to large display screens. Improving their efficiency could reduce energy use and enhance performance across a wide range of technologies. ...
Scientists discovered a protein secreted by a deep-sea extremophile—an organism adapted to extreme environmental conditions—that self-assembles into a biofilm and is highly stable, boosting its potential for biomedical applications.
