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...

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...

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...

Scientists of Karlsruhe Institute of Technology (KIT) and École Poly-technique Fédérale de Lausanne (EPFL) have reported that they achieved the fastest distance measurement attained so...

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

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...

Different instruments are needed to study the interaction of contact surfaces at different length scales. Tribometers measure the coefficient of friction but they...

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...

Since 1998, almost 2,000 shoebox-sized satellites known as CubeSats have been launched into space. Due to their small frame and the fact that they can be made from off-the-shelf...

A breakthrough imaging technique developed by Cornell researchers shows promise in decontaminating water by yielding surprising and important information about catalyst particles that can't be...

At the scale of bridges or buildings, the most important force that engineered structures need to deal with is gravity. But at the scale of microelectro-mechanical systems (MEMS) — devices like...

A portable, stable, standards-quality radiation thermometer was invented that can measure temperatures between -50 °C (-58 °F) to 150 °C (302 °F). The corresponding infrared...

Microrobots that can deliver drugs to specific spots inside the body while being monitored and controlled from outside the body have been developed that also can treat tumors in the...

A new MIT-developed technique enables robots to quickly identify objects hidden in a three-dimensional cloud of data, reminiscent of how some people can make sense of a densely patterned “Magic Eye” image if...

Some organic materials cannot be utilized similarly to silicon semiconductors in optoelectronics. Whether in solar cells, light-emitting diodes, or in transistors, what is important is the bandgap, i.e....

When light gets scattered as it passes through a translucent material, the emerging pattern of “speckle” looks as random as static on a television screen with no signal. But it...

Autonomous vehicles relying on light-based image sensors often struggle to see through blinding conditions such as fog. Sub-terahertz wavelengths, which are between microwave...

Adversarial techniques were developed that can make objects “invisible” to image detection systems that use deep-learning algorithms. These techniques can also trick systems...

Researchers have created inexpensive, full-color, 2D and 3D holograms that are more realistic and brighter, and can be viewed at wider angles than current holograms.

It has been known since the early 1960s that hexagonal sampling is the optimal sampling approach for isotropically band-limited images, providing a 13.4% improvement in sampling efficiency over...

Until about 20 years ago, scientists relied on chemical fluorescent dyes to make biological molecules visible. To look inside cells, stain organelles, and perform...
