Absolute Pressure Sensor

Mouser Electronics, Inc. (Mandfield, TX) is now stocking the 2SMPB-01-01 Absolute Pressure Sensor from Omron Electronics. Based on Omron’s MEMs technology, this highly accurate, small size absolute pressure sensor can measure altitude, atmospheric pressure or water depth, and can detect height differences of as little as 50 centimeters. The sensor provides pressure accuracy relative to a perfect vacuum to ±0.06 Pa, and absolute pressure accuracy in the range –400 to +400 Pa. The Omron Electronics 2SMPB-01-01 can operate in three different power modes: standard, high-accuracy and low-power mode. The 2SMPB-01-01 has a power consumption of 9 µA typical, and is fully temperature compensated with an absolute temperature accuracy of ±2 °C. http://www.mouser.com/new/omronelectronics/Omron-2SMPB-Sensor/

Meeting Industry Standards for Sanitation in The Food Industry

Food service equipment manufacturing and electropolishing go hand in hand. Parts said to be made of “Food Grade Stainless” typically have undergone finishing operations such as passivation or electropolishing to enhance the cleanliness and corrosion resistance. With electropolishing, you also receive the added benefits of microfinish improvement and deburring.

Effects of Sterilization Methods on Specialty Optical Fibers and Terminations

Optical fibers and terminations were subjected to different sterilization techniques, including multiple autoclaving and treatments with peracetic acid, E-beam and UV radiation. Effects of different sterilization techniques on key optical and mechanical properties of the fibers and the terminations were revealed.

Coming Soon - FDM vs. PolyJet – Similarities & Distinctions

Stratasys offers two different 3D printing technology options. FDM (Fused Deposition Modeling) and PolyJet are distinctly different, yet they have much in common. To help you understand which 3D printing technology best meets your needs, Fred Fischer, Director of Applications & Materials and former Applications Engineer for Stratasys, will share his insights on FDM and PolyJet and what these two technologies can offer- for everything from prototyping and design, to end use parts. He will cover operations, output qualities and material offerings.

Coming Soon - Ultrasonic Stir Welding – A New Solid-State Weld Process for Better Weld Quality and Longer Tool Life

Ultrasonic Stir Welding (USW) is a solid state stir welding process, meaning that the weld work piece does not melt during the welding process. The process uses a stir rod to “stir” the plasticized abutting surfaces of two pieces of metallic alloy that forms the weld joint. Because of the independent control of USW process elements, closed-loop temperature control can be integrated into the system so that a constant weld nugget temperature can be maintained during welding.

Automated Imaging System Analyzes Underground Root Systems

Researchers from the Georgia Institute of Technology and Penn State University have developed an automated imaging technique for measuring and analyzing the root systems of mature plants. The technique, believed to be the first of its kind, uses advanced computer technology to analyze photographs taken of root systems in the field. The imaging and software are designed to give scientists the statistical information they need to evaluate crop improvement efforts.“We’ve produced an imaging system to evaluate the root systems of plants in field conditions,” said Alexander Bucksch, a postdoctoral fellow in the Georgia Tech School of Biology and School of Interactive Computing. “We can measure entire root systems for thousands of plants to give geneticists the information they need to search for genes with the best characteristics.”Imaging of root systems has, until now, largely been done in the laboratory, using seedlings grown in small pots and containers. Such studies provide information on the early stages of development, and do not directly quantify the effects of realistic growing conditions or field variations in water, soil, or nutrient levels.The technique developed by Georgia Tech and Penn State researchers uses digital photography to provide a detailed image of roots from mature plants in the field. Individual plants to be studied are dug up and their root systems washed clean of soil. The roots are then photographed against a black background using a standard digital camera pointed down from a tripod. A white fabric tent surrounding the camera system provides consistent lighting.The resulting images are then uploaded to a server running software that analyzes the root systems for more than 30 different parameters, including the diameter of tap roots, root density, the angles of brace roots, and detailed measures of lateral roots.SourceAlso: Learn about Strobing to Enhance Display Legibility.

Fast-Charging Batteries Have 20-Year Lifespan

Scientists at Nanyang Technology University (NTU) have developed ultra-fast charging batteries that can be recharged up to 70 percent in only two minutes. The new-generation batteries also have a long lifespan of over 20 years, more than 10 times compared to existing lithium-ion batteries.In the new NTU-developed battery, the traditional graphite used for the anode (negative pole) in lithium-ion batteries is replaced with a new gel material made from titanium dioxide. Titanium dioxide is an abundant, cheap and safe material found in soil. Naturally found in spherical shape, the NTU team has found a way to transform the titanium dioxide into tiny nanotubes, which is a thousand times thinner than the diameter of a human hair. The development speeds up the chemical reactions taking place in the new battery, allowing for superfast charging.  The breakthrough has a wide-ranging impact on all industries, especially for electric vehicles, where consumers are put off by the long recharge times and its limited battery life.SourceAlso: Learn about a Screening Technique for New Battery Chemistries.
