In discussing fatigue life, it is important to distinguish between disc springs and conical spring washers, as they differ by design and intended usage. Conical spring washers are...

Researchers at NASA’s Johnson Space Center improved their Flash Thermography capabilities by incorporating transient and lock-in thermography. By...

Advanced driver-assistance systems and autonomous drive technologies increase the complexity of automotive integrated circuits (ICs), making it harder to ensure that...

Additive manufacturing, or 3D printing, is a rapidly growing field in which solid objects can be produced layer-by-layer. This...

Researchers at NASA’s Armstrong Flight Research Center have identified and evaluated recently available miniature spectrometers that enable compact and robust pyrometry...

Unwanted porosity is typical to many manufacturing processes — from traditional casting to additive manufacturing (3D printing) — and is difficult to avoid entirely....

Time-of flight mass spectrometers are commonly used in analytical chemistry and many other applications. They contain a region where ions travel toward a detector. A new geometry was developed that...

A current-steering digital-to-analog converter (DAC) was developed that achieves improved switching times (up to 75% faster) in high-speed (gigahertz), high-resolution (8-14...

Existing techniques for creating nano-structures are limited in what they can accomplish. Etching patterns onto a surface with light can produce 2D nano-structures but doesn’t work for 3D structures....

A team of bioengineers supported through a Small Business Innovation Research grant from the National Institute of Biomedical Imaging and Bioengineering (NIBIB) has...

Researchers at the University of Houston have created an inexpensive system that can detect lead in tap water at levels commonly accepted as dangerous, using a lens made with an...

Ordinary WiFi can easily detect weapons, bombs, and explosive chemicals in bags at museums, stadiums, theme parks, schools, and other public venues using a low-cost suspicious...

Many applications in science and industry require an apparatus that creates a controlled amount of a fluid introduced into another fluid. For instance, some material corrosion testing applications...

Along with intensity and color, polarization is a property of light that can provide useful information for scene analysis; however, the human eye and most cameras cannot detect...

From cellphones to satellites, industry spends millions on traditional gold alloy electrical contact coatings. While gold and other metal alloys have been an industry standard to protect metal components...

The mechanical properties of sheet metal materials are directional. Their deformation behavior and their strength differ significantly depending on the viewing direction; for example, in the direction of rolling, or...

Optical range measurements, already used in manufacturing and other fields, may help overcome practical challenges posed by structural fires, which are too hot to measure with conventional...

Many devices use light to probe the quantum states of atoms in a vapor confined in a small cell. Atoms can be highly sensitive to external conditions, and therefore make superb detectors....

GPS signals do not penetrate very deeply or at all in water, soil, or building walls, and therefore can’t be used by submarines or in underground activities such as surveying mines. GPS also...

Researchers at Rensselaer Poytechnic Institute (RPI) have developed a new approach to optical imaging that makes it possible to quickly and economically monitor multiple molecular interactions in a...

Outsourcing machine learning is a rising trend in industry. Major tech firms have launched cloud platforms that conduct computation-heavy tasks, such as running data through a convolutional...

Traditional methods, such as reverse osmosis, that remove contaminants from water are expensive and energy-intensive. Researchers have developed technology to remove contaminants from water,...
