Materials with controlled porosity have found diverse applications in separation, catalysis, energy storage, sensors and actuators, tissue engineering, and drug delivery. Multiple...

A method was developed that enables information to be contained in simple plastic foils with a thickness of less than 50 μm, which is thinner than a human hair. Organic luminescent molecules...

3D printing via direct laser writing involves a computer-controlled focused laser beam that acts as a pen and creates the desired structure in the printer ink — a photoresist. In this...

An advanced manufacturing process was developed to produce nano-structured rods and tubes directly from high-performance aluminum alloy powder in a single step. Using a Solid Phase Processing...

A radically new kind of airplane wing, assembled from hundreds of tiny identical pieces, can change shape to control the plane’s flight, and could provide a significant boost in...

Researchers have 3D-printed an all-liquid device that, with the click of a button, can be repeatedly reconfigured on demand to serve a wide range of applications from making battery materials to screening drug...

A smartphone app was developed that allows a user to easily program any robot to perform a mundane activity such as picking up parts from one area and delivering them to another. The app, called VRa, uses...

An automated system designs and 3D-prints complex robotic parts that are optimized according to an enormous number of specifications. The system fabricates actuators — devices that mechanically...

Between walking and running, human gaits can cover a wide range of speeds; for example, at low speeds, the metabolic rate of walking is lower than that of running in a slow jog....

Excess heat given off by smartphones, laptops, and other electronic devices contributes to malfunctions and, in extreme cases, can even cause lithium batteries to explode. To guard...

For decades, microchip transistors have become smaller, faster, and cheaper; however, miniaturization has reached a natural limit, as completely new problems arise when a length scale of only a...

In the wake of recent developments that have reduced fan and jet noise contributions to overall jet-engine noise, aircraft designers are turning their attention toward reducing engine core...

Magnetic resonance imaging (MRI) uses magnetic fields and radio waves to create images of organs and tissues in the human body, helping doctors diagnose potential problems or diseases. Doctors use MRI to...

Robotics has traditionally focused on industrial applications in which robots require strength and precision to carry out repetitive tasks. These robots flourish in highly...

Landing is stressful on a rocket’s legs because they must handle the force from the impact with the landing pad. One way to combat this is to build legs out of materials that absorb some of...

Recently discovered two-dimensional (2D) materials with superlative properties have the potential to advance semiconductors but creating 2D devices with both good electrical contacts and...

Unlike water, liquid refrigerants and other fluids that have a low surface tension spread quickly into a sheet when they come into contact with a surface. For many industrial...

A soft and conformable health monitor can broadcast electrocardiogram (ECG), heart rate, respiratory rate, and motion activity data as much as 15 meters to a portable recording...

In the future, soft, animal-inspired robots may be safely deployed in difficult-to-access environments in which rigid robots cannot currently be used such as inside the human body or in spaces that are too...

In order to qualify miniature springs, manufacturers of these systems rely on commercially available testers that are designed for large-scale springs (>0.5" diameter). Commercially available spring...

A 3D-printed polymer-based foam structure was developed that responds to the force of a shock wave to act as a oneway switch, a long sought-after goal in shock research. The...

Researchers have created 3D-printed flexible mesh structures that can be controlled with applied magnetic fields while floating on water. The structures can grab small objects and carry water droplets, giving them...

The production of precision products depends on robot control systems knowing the location of the adhesive bonding head or welding head to the nearest millimeter at all times. This means the robot...

Accurately detecting, locating, and quantifying leaks of methane — the main component of natural gas and a major fuel source worldwide — is critically important for both environmental...

Although smartphones and other consumer cameras are increasingly used for scientific applications, it's difficult to compare and combine data from different...
