JILA strontium atomic clock sets new records in both precision and stability

Heralding a new age of terrific timekeeping, a research group led by a National Institute of Standards and Technology (NIST) physicist has unveiled an experimental strontium atomic clock that has set new world records for both precision and stability—key metrics for the performance of a clock. The clock is in a laboratory at JILA, a joint institute of NIST and the University of Colorado Boulder. Described in a new paper in Nature,* the JILA strontium lattice clock is about 50 percent more precise than the record holder of the past few years, NIST’s quantum logic clock.

Webinar: A new “damage free” approach to defect analysis using micro ATR FTIR chemical imaging of delicate materials

The webinar will start with an overview of current FTIR microscopy and imaging techniques and will expand on the newly introduced low pressure, damage-free approach to attenuated total reflectance Fourier transform infrared micro-imaging using Agilent’s unique “live ATR FTIR imaging” technique. Examples will come from the fields of electronic components testing, polymers, pharmaceuticals, and art conservation research, where microscopic chemical analysis of samples that are often very fragile (and/or valuable) are crucial to many aspects of materials research and testing.

NASA offers space tech grants to early career university faculty

NASA’s Space Technology Mission Directorate seeks proposals from accredited US universities from outstanding early career faculty members who are beginning their independent careers. NASA expects to award about five grants this fall, funded up to $200,000 each per year for as many as three years, based on the merit of proposals and availability of funds. Funded research will investigate unique, disruptive or transformational space technologies in areas such as soft machines for robotic mobility and manipulation, science-based digital materials and manufacturing, and low size, weight, and power lasers.
