Print 3D Metal Objects at Room Temperature Using a Conductive Metallic Gel

Professor Michael Dickey, of North Carolina State University, and his team have developed a unique process that allows you to print 3D metal objects that have good electric and thermal conductivity as well as good structural properties.

Nanoscale 3D Structure to Control Light

3D nanometer-scale metamaterial structures hold promise for advanced optical isolators.

Strengthening Electron-Triggered Light Emission

A wavelength of visible light is about 1,000 times larger than an electron, so the way the two affect each other is limited by that disparity. Now, researchers have come up with a way to make...

Caterpillar-Inspired Soft Robotics Locomotion

Researchers have demonstrated a caterpillar-like soft robot that can move forward, backward, and even dip under narrow spaces. Its movement is driven by a novel pattern of silver nanowires.

Nanomaterial Promises Big Benefits for Bendable Electronics

An international team of scientists is developing an inkable nanomaterial that they say could one day become a spray-on electronic component for ultra-thin, lightweight, and bendable displays and devices.

Printing Microchip Patterns on Curvy Surfaces

There’s still more to explore with REFLEX, but this process could open new possibilities for new materials and microstructures across fields from electronics to optics to biomedical engineering.

New Programmable Smart Fabric Responds to Temperature, Electricity

A new smart material is activated by both heat and electricity, making it the first ever to respond to two different stimuli. The work paves the way for a wide variety of potential applications, including clothing that warms up while you walk.

Surgical Sutures Inspired by Human Tendons

Next-generation sutures can deliver drugs, prevent infections, and monitor wounds.

Generative Design Puts Hydrogen Fuel Cell Development in High Gear

Toyota Research Institute of North America has developed a simulation-driven generative design method and applied it to the design of flow field microchannel plates, which direct the movement of fluid reactants in microreactors like hydrogen — oxygen fuel cells.

5Ws of ‘Talking’ Concrete

A new technology allows concrete to “talk,” decreases construction time and how often concrete pavement needs repairs while also improving the road’s sustainability and cutting its carbon footprint.

Developing High-Fidelity Martian Regolith Simulants

Researchers at the Exolith Lab, University of Central Florida, are simulating realistic materials to be used for testing a range of technologies for Martian surface interactions and operations.

Smart Material Challenges Newton’s Laws of Motion

The team has developed a prototype metamaterial that uses electrical signals to control both the direction and intensity of energy waves passing through a solid material.

Superlubricity Coating for Nearly Friction-Free Surfaces

Scientists at the Department of Energy’s Oak Ridge National Laboratory have invented a coating that could dramatically reduce friction in common load-bearing systems with moving...

Engineers “Grow” Atomically Thin Transistors on Top of Computer Chips

Emerging AI applications, like chatbots that generate natural human language, demand denser, more powerful computer chips. But semiconductor chips are traditionally...

The World’s First Wood Transistor

Transistors are considered by some to be an invention just as important to humanity as the telephone, the light bulb, or the bicycle. Today, they are a crucial component in modern electronic devices, and...

Sensors that Operate at High Temperatures and in Extreme Environments

Extreme environments in several critical industries — aerospace, energy, transportation, and defense — require sensors to measure and monitor numerous factors under...
