Treatment Prevents Corrosion in Steel and Concrete Structures

NASA’s Kennedy Space Center is located on prime beachfront property along the Atlantic coast of Florida on Cape Canaveral. While beautiful, this region presents several challenges, like temperamental coastal weather, lightning storms, and salty, corrosive, sea breezes assaulting equipment and the Center’s launch pads. The constant barrage of salty water subjects facility structures to a type of weathering called spalling, a common form of corrosion seen in porous building materials such as brick, natural stone, tiles, and concrete. In spalling, water carries dissolved salt through the building material, where it then crystallizes near the surface as the water evaporates. As the salt crystals expand, this creates stresses which break away chips, or spall, from the surface, causing unsightly and structural damage.

Voltage Controller Saves Energy, Prolongs Life of Motors

In the late 1970s, Frank Nola, an engineer at NASA’s Marshall Space Flight Center, had an idea for reducing energy waste in small induction motors. The idea, a method to electronically adjust the voltage in accordance with the motor’s load, was patented in 1984. The voltage controllers have become known as Nola devices, and they are still as useful today as they were more than 20 years ago, as they can be applied anywhere an AC induction motor is being used at a constant speed but with a variable load. These have the ability to save operators a great deal of energy when the motor is lightly loaded, which translates into savings in cost and resources.

Sensor Network Provides Environmental Data

The National Biocomputation Center is a joint partnership between the Stanford University School of Medicine’s Department of Surgery and NASA’s Ames Research Center. Founded in 1997, the goal of the Biocomputation Center has been to develop advanced technologies for medicine. Researchers at this center apply 3-D imaging and visualization technologies for biomedical and educational purposes, as well as support NASA’s mission for human exploration and development of space. It is the test bed for much of NASA’s advanced telemedicine research.

Methods to Detect Minute Quantities of Acrylamide in Foods

A large global food company seeks a rapid, inexpensive, and reliable test that can detect even small levels of acrylamide in fried snack foods. What is desired is a rapid, simple, inexpensive method that could be performed essentially online in a fried snack plant by line operators or quality assurance analysts. Ideally, it would require little, if any, sample preparation, would provide results in less than one hour, and would be selective, sensitive, and quantitative for acrylamide in a potato chip.
