Cornell researchers have developed a two-phase liquid crystal system that can rapidly change—and hold—its shape, transforming from a transparent thin liquid film to an opaque emulsion, and then back again, all with a ...
The mechanical strength and toughness of engineering materials are often mutually exclusive, posing challenges for material design and selection. To address this, a research team from The Hong Kong Polytechnic University ...
Nanoparticles—the tiniest building blocks of our world—are constantly in motion, bouncing, shifting, and drifting in unpredictable paths shaped by invisible forces and random environmental fluctuations.
Carbon emissions continue to increase at record levels, fueling climate instability and worsening air quality conditions for billions in cities worldwide. Yet despite global commitments to carbon neutrality, urban policymakers ...
Magnetic micropillar arrays consist of tiny, vertical pin-shaped structures, arranged in a grid-like pattern. These micropillars can change their shape to a pre-programmed geometry when exposed to a magnetic field. They are ...
A powerful new method to control magnetic behavior in ultra-thin materials could lead to faster, smaller and more energy-efficient technologies, a study suggests.
Cleaning products, candles, cribs, and cosmetics are just a few of the common household items that emit formaldehyde, a colorless, odorless chemical that, when present in the air at levels higher than 0.1 parts per million, ...
A new coating for glass developed by Rice University researchers and collaborators could help reduce energy bills, especially during the cold season, by preventing heat-loss from leaky windows. The material—a transparent ...
Caltech scientists have found a fast and efficient way to add up large numbers of Feynman diagrams, the simple drawings physicists use to represent particle interactions. The new method has already enabled the researchers ...
For a long time, universities worked off a simple idea: knowledge was scarce. You paid for tuition, showed up to lectures, completed assignments and eventually earned a credential.
