Laser Confocal Scanning Microscope

The new Olympus (Waltham, MA) LEXT® OLS5000 3D laser confocal scanning microscope delivers precise imaging in a fast, easy-to-use system for research and development and quality control inspection. 4K scanning technology and optics designed specifically for the OLS5000 microscope enable the detection of near-perpendicular features and small steps at close to nano-scale. The system acquires data four times faster and improves the user experience with intuitive software designed to automate many common settings. An expansion frame and a dedicated, long working distance (LWD) lens perform precise measurements on samples up to 210 mm in height and concavities up to 25 mm deep — even those with uneven surface cracks.

Scientists Develop Extreme Light Trapping Technology

A silicon solar cell harvests the energy of the sun as light travels down through light-absorbent silicon. To reduce weight and cost, solar cells are thin, and while silicon absorbs visible light well, it captures less than half of the light in the near-infrared spectrum, which makes up one-third of the sun’s energy. The depth of the material limits absorption. But what if light within the cell could be channeled horizontally so that silicon could absorb its energy along the width of the cell rather than its depth?

A Semiconductor Breakthrough: Carbon Nanotubes Boost Thermoelectric Performance

In a report published in October, scientists from the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) used single-walled carbon nanotubes (SWNCTs) to advance the thermoelectric performance of organic semiconductors. The carbon nanotube thin films, they said, could ultimately be integrated into fabrics to convert waste heat into electricity or serve as a small power source.

SAE J2360 – A Global Automotive Gear Oil Performance Standard

Providing durability in the protection of axles in commercial vehicles and passenger car vehicles is a key requirement for axle manufacturers, OEMs, and the military. The SAE J2360 performance standard is one way in which an oil marketer or OEM can ensure that a lubricant has been designed to achieve a high level of performance. With the SAE J2360 performance specification, manufacturers can specify and identify high-quality lubricants for use in their equipment anywhere in the world. Fleet owners benefit by gaining access to quality gear lubricants that will reduce equipment downtime and maintenance.
