When a material heats up, its electrical resistance often rises. The harder question is what, exactly, is getting in the way. The electrons carrying the current may be scattered by vibrations of the material's atomic lattice, ...
Imagine this. You pick up a contact lens from its container and—yikes!—it falls on the bathroom floor. Before you know it, your cat pounces, claws out. By the time you wrestle it back, the lens looks like a tiny chew toy. ...
A research team at the University of Vienna led by physicist Jani Kotakoski demonstrates how the shape of nanopores in hexagonal boron nitride—the electrically insulating counterpart to graphene, also known as "white graphene"—can ...
From targeted cancer treatments to self-healing materials and microscopic robots, many emerging technologies depend on molecules that can be controlled with light. Researchers at Tohoku University have now developed a way ...
An international team led by researchers from the University of São Paulo (USP) in Brazil has developed an innovative method to identify stars that have consumed the planets around them. The technique detects variations in ...
Carbon dioxide (CO₂) is usually discussed as something the world needs to get rid of. Activities such as the burning of fossil fuels for daily use, including electricity and transportation, and industrial applications release ...
Restructuring a molecule without rebuilding it from scratch is an increasingly important goal in modern organic chemistry. Skeletal editing is an approach that helps chemists explore new chemical structures and simplify the ...
Despite all the advertisements for engagement rings and necklace gifts, natural diamonds are imperfect. Their carbon atoms are arranged in a cubic lattice, but they nonetheless contain several types of crystallographic defects ...
Electrons, particles that carry a negative electric charge, typically move through materials. At low densities and temperatures, however, the electrical repulsion between them can overpower their tendency to move, prompting ...
Plastic pollution is one of the most urgent environmental challenges of the 21st century. As larger plastic debris breaks down through mechanical, photochemical and biological processes, it forms microplastics that have been ...
