Macrospray® nozzles produce consistent mists at very low pressure. The nozzles have a uniformly distributed droplet size (10–30 μm Sauter Mean Diameter), which provides greater contact between deodorant, for example, and odorcausing particles or dust. Droplet size can be tuned for the degree of dust...

A patented, one-piece, fiber-reinforced plastic composite chassis, produced by sheet molding compression, uses a highglass-content vinyl ester composite structural material, toughened with urethane for fatigue and damage tolerance.

An organization needs an inexpensive device to deliver a pre-measured amount of liquid evenly to a surface. The applicator is intended for a single use, must be able to be sterilized after final assembly, and needs to hold enough liquid or gel to cover about 1 to 3 square feet of surface...

A torque-feedback mechanism must measure force, pressure, and displacement. The hybrid system or multi-part assembly requires haptic, visual, sound, temperature, or vibration feedback instruments. The technology may take the form of either a standalone sensor cube that flashes according to pressure, or a material that...

Marcia Domack and John Wagner, engineers in the Advanced Materials and Processing Branch at NASA Langley Research Center, have worked with Boston-based metal fabricator Spincraft, focusing on a one-piece manufacturing process called spin forming. The team used...

A team of Harvard scientists has developed a slick way to prevent the troublesome bacterial communities from ever forming on a surface.The researchers used their recently developed technology, dubbed SLIPS (slippery-liquid-infused porous surfaces), to effectively create a hybrid surface that is smooth and slippery...

A University of Missouri equine veterinarian, Kevin Keegan, has developed a way to detect lameness in horses using a motion detection system called the “Lameness Locator.” It also detects lameness earlier than veterinarians using the traditional method of a subjective eye test.

Using piezoelectric materials, Georgia Tech researchers have replicated the muscle motion of the human eye to control camera systems in a way designed to improve the operation of robots. This new muscle-like action could help make robotic tools safer and more effective for MRI-guided...

Batoid rays, such as stingrays and manta rays, are fast and highly maneuverable, and can cruise for long distances in the open ocean. Engineers are now trying to emulate the seemingly effortless but powerful swimming motions of rays by engineering their own ray-like machine modeled on nature.The team...

A University of Georgia research team has developed a single-step method to rapidly and accurately detect viruses, bacteria, and chemical contaminants. Yiping Zhao, professor of physics in the UGA Franklin College of Arts and Sciences, along with doctoral students Jing Chen and Justin Abell,...

Kansas State University researchers Hayder Rasheed, associate professor of civil engineering, and Yacoub Najjar, professor of civil engineering, are collaborating to better detect and measure damage in concrete bridges. The researchers have created a bridge health index - a rating system...

FLOWBEC (Flow and Benthic Ecology 4D) is a National Oceanography Centre (NOC)-led project that brings together a consortium of UK researchers to investigate the effects of devices that harness tide and wave energy by monitoring environment and wildlife behavior at various test sites. The...

Three years of their hard work plunged in the Atlantic Ocean on a Monday in July and a group of NASA engineers could not have been more thrilled.They were part of the Inflatable Reentry Vehicle Experiment (IRVE-3) team that is working to develop an inflatable heat shield. The technology...

An international team of scientists has published the results of a 2004 experiment to fertilize oceans with iron. The ocean fertilization was an effort to reduce the carbon at the water’s surface and potentially...

Hybrid hydraulic technologies were tested by Navy and Army engineers seeking to achieve greater energy efficiencies and reduce costs among the Department of Defense's heavy construction fleet.

More than 40 vendors and five universities showcased nearly 75 different technologies during the 2012 Robotics Rodeo at Fort Benning, GA.

For years, the U.S. Navy has employed human divers, equipped with sonar cameras, to search for underwater mines attached to ship hulls. The Navy has also trained dolphins and sea lions to search for bombs on and around vessels.
