Visualizing Motion of Water Molecules for Liquid-Based Electronics

A high-resolution inelastic x-ray scattering technique was used to measure the strong bond involving a hydrogen atom sandwiched between two oxygen atoms. This hydrogen bond is a quantum-mechanical phenomenon responsible for various properties of water, including viscosity, that...

Briefs: Tubing & Extrusion

The Air Force has developed improved devices for hemostatic management of patients with life-threatening blood loss from an arterial wound or surgery. Current aortic occlusion devices...

Briefs: Electronics & Computers

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...

Feature Image
Briefs: Sensors/Data Acquisition

A new type of oximeter — or blood-oxygen sensor — is made of organic electronics printed on bendable plastic that molds to the contours of the body. Unlike fingertip oximeters, it can detect...

Exhaust Plume Analyzer

Exhaust plumes emanating from smoke stacks at power plants or other industrial facilities can have adverse impacts on local aviation during periods of calm winds. Adverse impacts can be exacerbated if the temperature is low or the atmosphere is unstable. While low oxygen concentrations and elevated temperatures inside the...

Carbon Dioxide Collection and Pressurization Technology

Mars is the ultimate destination for NASA's human exploration program. In Situ Resource Utilization (ISRU) is a key technology required to enable such missions. The goals of using resources available at the exploration site are to reduce launch and delivered mass, reduce risk and cost,...

Briefs: Software

What had been a peaceful and productive mission for the six men aboard the Russian space station Mir, including U.S. astronaut Jerry Linenger, nearly became a tragic...

Briefs: Medical

Currently, concussion is measured by the symptoms someone experiences, but it is difficult to know what is happening in the brain in any one person. To address this problem, a portable brain imaging system was...

Feature Image
Briefs: Test & Measurement

The most common methods for glucose self-testing involve monitoring glucose levels in blood. These conventional measurements are not suitable for preventing hypoglycemia during exercise. The...

Compact Termination for Structural Soft Goods

Space environments are particularly harsh for the high-strength fibers NASA relies on for soft structures. Kevlar, Nomex, Nylon, and other synthetic fibers are broken down by exposure to the combination of vacuum, atomic oxygen, and ultraviolet radiation. Glass fiber offers unique advantages for...

Printing Ink Removes Oxygen in Sealed Packages

Oxygen adversely impacts food flavor and nutrition. NASA’s proposed five-year shelf life for astronaut food requires aggressive measures to minimize oxygen. Previously, NASA packaged foods in containers with a high oxygen and moisture barrier. These materials have limiting properties. They contain...

Cobalt Oxygen-Evolving Catalysts for Clean Solar Fuel

By splitting a water molecule into two atoms of hydrogen and one of oxygen, scientists can use the Sun’s energy to make a clean fuel. Splitting a water molecule requires a metal catalyst to get the reaction started. Recently, much scientific attention has focused on cobalt, a relatively...

Briefs: Materials

Batteries and combustion engines each have distinctive benefits and limitations. Batteries have simple construction and operate silently; however, their energy density (i.e., the energy per unit volume) is poor, and...
