NASA Spinoff: NASA’s UV Radiation Research Keeps Sun Worshipers Safe

Studying radiation effects on spacecraft led to a personal Sun exposure monitor. To understand the Sun’s impacts on Earth, NASA initiated the Living with a Star program in 2001, and began developing a key research satellite: the Solar Dynamics Observatory (SDO). One of the instruments created for the SDO was the Extreme Ultraviolet Variability Experiment (EVE), tasked with measuring extreme ultraviolet (UV) radiation, which plays a key role in atmospheric heating and satellite drag. In 2005, Goddard Space Flight Center scientist Shahid Aslam joined other researchers in developing EVE.

Product of the Month: May 2015

Sensirion, Westlake Village, CA, introduced a gas sensor that, according to the company, is the first in the world to be based on multi-pixel technology. This allows the sensor to perceive its surroundings using various receptors that, with the help of intelligent algorithms and pattern recognition, are able to detect the type and concentration of gases. The single sensor is capable of detecting and distinguishing between different gases. It measures 2.45 × 2.45 × 0.75 mm, and can be integrated anywhere. Using the sensor, mobile devices will be able to sense their surroundings in order to measure indoor air quality, determine the alcohol content of a person’s breath, or recognize smells.

3D-Printed Functional Antenna Arrays Operate on Exterior of COSMIC-2 Satellites

FDM® (Fused Deposition Modeling™) technology and ULTEM 9085 thermoplastic Stratasys Direct Manufacturing (RedEye, Solid Concepts, and Harvest Technologies) Eden Prairie, MN 866-882-6934 www.redeyeondemand.com In 2006, a satellite mission called the Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC-1) was put into orbit. The purpose of the instrument was to collect global ionospheric and atmospheric data of temperature, moisture, and pressure, including hard-to-sample areas such as above oceans and polar regions. The project was led by the University Corporation for Atmospheric Research (UCAR), a consortium of more than 70 research universities in the US, and Meteorological Society of the Republic of China (Taiwan). Since its inception, the COSMIC-1 project has contributed to a wide range of scientific investigations and improvements in weather forecasting.

Increased Alignment in Carbon Nanotube Growth

Ames Research Center, Moffett Field, California The combination of electronic and mechanical properties of carbon nanotubes (CNTs) has led to wide-ranging investigation of their potential in future electronics and computing, sensors, electrodes, and composites. A method and system for fabricating an array of two or more CNT structures on a coated substrate surface was developed.

Process to Fabricate Specific Sized Monodisperse Polystyrene Microparticles

Langley Research Center, Hampton, Virginia A new method was developed to prepare monodisperse nano to microparticles of polystyrene ranging from 0.5 to 2.5 microns in relatively large-quantity batches (2 L, 10% by weight in water). Current commercial sources are very expensive and can typically only be acquired on a relatively small scale. Monodisperse polystyrene in this size range is an important component of laser velocimetry measurements in wind tunnels, but has many other potential uses. Polystyrene microparticles have uses in paints/coatings, adhesives, bio/immunoassays, reaction catalysts, and chromatography materials. The main benefits of this technology are low cost, scalability, and selectable size.
