Researchers provide the first experimental and theoretical proof that it is possible to form strong, stable attractions between some of the heavier elements in the periodic table -- such as arsenic or even antimony. Because hydrogen is not involved in creating the bond between these elements, these new materials should be resistant to water and humidity.

Static electricity is one of the most common, yet poorly understand, forms of power generation. A new study suggests the cause of this hair-raising phenomenon is tiny structural changes that occur at the surface of materials when they come into contact with each other. The finding could someday help technology companies create more sustainable and longer-lasting power sources for small electronic devices.

It starts as a persistent and irritating pain in the foot or lower leg, then it gets more intense, maybe with swelling, and soon a runner knows she's being sidelined by one of the most common running injuries: a stress fracture. These tiny cracks in the bone can halt training for months or even end a sports season. A segment of the multibillion-dollar wearables industry aims to save potential victims from this fate, but an engineering professor found a major problem: the devices are measuring the wrong thing.

Engineers have been taking a novel approach to the development of engineering components produced using additive manufacturing.

Microsilica, which is also known as silica fume, or condensed silica fume, is a mineral admixture composed of very fine solid glassy spheres of...

Researchers discovered that the distance between dislocations in nanolayer interfaces of pearlite can determine how much the material can stretch or contract without breaking (ductility). The dislocations are disruptions in the regular arrangements of atoms in nanolayers. This discovery opens the possibility of engineering materials with higher ductility by simply manipulating the spacing between their dislocations and may improve the safety of structures such as buildings and bridges in earthquakes.

Research shows that drones can be more effective and safer in crash mapping of vehicular highway accidents than conventional methods. Drones using new imaging technology allows highway safety officers to capture and print 3D composites of crash sites and reduce mapping time and improve traffic flow following a crash by 60 percent.

Keeping road pavement in good shape saves money and energy and reduces greenhouse gas emissions, more than offsetting pollution generated during road construction, according to a new study.

Icy weather is blamed for multibillion dollar losses every year in the United States, including delays and damage related to air travel, infrastructure and power generation and transmission facilities. Now researchers have reported creating a durable silicone polymer coating capable of repelling ice from any surface.

Using stimuli-responsive materials and geometric principles, engineers have designed structures that have 'embodied logic.' Through their physical and chemical makeup alone, they are able to determine which of multiple possible responses to make in response to their environment.

A new study shows that over time, bears get used to drones. Previous work indicated that animals behave fearfully or show a stress response near drone flights. Using heart monitors to gauge stress, however, researchers here found that bears habituated to drones over a 3 to 4-week period and remained habituated.
