A new method increases the service life of concrete structures by reducing the infiltration rates of deleterious ions. The key is a nano-sized additive that slows down penetration of...

Most metals, with the notable exception of gold, tend to oxidize when exposed to air and water. This reaction — which produces rust on iron, tarnish on silver, and verdigris on copper or...

Eagles can store energy in their feet without having to continuously contract their muscles to then jump high or hold on to prey. New materials have been created that can store energy this way. The...

Current density is the amount of electrical current per cross-sectional area at a given point. As transistors in integrated circuits become smaller and smaller, they need higher and higher...

Researchers have 3D-printed an array of light receptors on a hemispherical surface. This discovery could lead to a “bionic eye” that could someday help blind people see or sighted...

Plastics are often derived from petroleum, contributing to reliance on fossil fuels, and driving harmful greenhouse gas emissions.

Computer processors have continued to shrink down to nanometer sizes where there can be billions of transistors on a single chip. This phenomenon is described under Moore's Law, which...

Additive manufacturing (3D printing) can be used to manufacture porous electrodes for lithium-ion batteries, but because of the nature of the manufacturing process, the design of these...

Researchers have demonstrated the ability to create amorphous metal (metallic glass) alloys on large scales using 3D printing technology. Metallic glasses lack the crystalline...

Wearable technologies are exploding in popularity in both the consumer and research spaces, but most of the electronic sensors that detect and transmit data from wearables are made of hard,...

Researchers have developed a method to simultaneously control diverse optical properties of dielectric waveguides by using a two-layer coating, each layer with a...

A technique that enables on-demand control of composite behavior could enable a variety of new capabilities for future rotorcraft design, performance, and maintenance. The focus of the research was on...

NASA's Langley Research Center, in collaboration with Michigan State University (MSU), has developed a microphone array that...
