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...

While different approaches have been used to create artificial muscles — including hydraulic systems, servomotors, shape-memory metals, and polymers that respond to stimuli — they all have limitations such...

Data Recorder

DATAQ^® Instruments, Akron, OH, announced the DI-4718B data recorder for applications that require signal conditioning. It can accommodate up to eight DI-8B-style amplifiers...

Optical coatings are critical for enhancing the transmission, reflection, polarization, and phase of light incident upon and passing through optical components. There are many different technologies used to...

How much does windshield glazing matter when cars drive themselves?

The color of a material can often tell how it handles heat. With clothing, for example, the darker the pigment, the warmer you're likely to feel on a hot day. Likewise, the more...

Researchers have created a fabric that automatically regulates the amount of heat that passes through, depending on conditions; for example, when conditions are warm and moist — such as those of a...

A system was developed that can remove radioactive cesium contamination from porous structures such as brick and concrete that are hard to clean, as well as contamination from...

There is a need for high-volume material testing/qualification but industry and researchers are currently limited by commercially available testing devices. Most wear testers can only handle one...

On September 1, 1961, NASA requested appropriations for initial land purchases on Merritt Island on Florida’s east coast to support the Apollo Lunar Landing Program. Designers quickly began developing...

Techniques to prevent frost and ice formation on surfaces rely heavily on heating or on liquid chemicals that need to be repeatedly reapplied because they easily wash away. Even advanced...

Nearly 70 percent of the energy produced in the United States each year is wasted as heat. Much of that heat is less than 100 °C and emanates from things like computers, cars, or...

Sensor Controller

The induSENSOR MSC7401 sensor controller from Micro-Epsilon, Ortenburg, Germany, is used for displacement and distance measurements and is operated with LVDT and LDR measuring gauges...

The critical angle lens reflector has commercial applications that supersede ordinary mirrored reflectors. The physics of the critical angle lens reflector are based on the optics...

Lithium batteries allow electric vehicles to travel several hundred miles on one charge. Their capacity for energy storage is well known — so is their tendency to occasionally...

The connection of plastics and metals poses a challenge due to the different physical properties of the two materials. All conventional joining options, such as bonds using adhesives or rivets,...

Anyone who skis, wears glasses, uses a camera, or drives a car is familiar with the problem: Coming into a humid environment from the cold causes eyewear, camera lenses, or windshields to...

Researchers created transparent polythene sheets that have a strength greater than aluminum – at a fraction of the weight.

The dyed threads change color when they detect a variety of gases.

Industrial machinery, agricultural equipment, transportation vessels, and home applications depend on lubricants; however, they leave a heavy environmental footprint. Common lubricants, oils,...

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...
