Eight Los Alamos innovations win R&D 100 Awards

DOE/Los Alamos National Laboratory
Grant and Award Announcement

Eight Los Alamos National Laboratory technologies won R&D 100 Awards last week at R&D Magazine's annual ceremony in Orlando, Florida.

Scalable clusters make HPC R&D easy as Raspberry Pi

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

A quest to help the systems software community work on very large supercomputers without having to actually test on them has spawned an affordable, scalable system using thousands of inexpensive Raspberry Pi nodes.

Diagnosing supercomputer problems

DOE/Sandia National Laboratories
Grant and Award Announcement

A team of computer scientists and engineers from Sandia National Laboratories and Boston University recently won the Gauss Award at the International Supercomputing conference for their paper about using machine learning to automatically diagnose problems in supercomputers.

New routes to renewables: Sandia speeds transformation of biofuel waste into wealth

DOE/Sandia National Laboratories
Peer-Reviewed Publication

A Sandia National Laboratories-led team has demonstrated faster, more efficient ways to turn discarded plant matter into chemicals worth billions.

First-ever US experiments at new X-ray facility may lead to better explosive modeling

DOE/Los Alamos National Laboratory
Peer-Reviewed Publication

For the first time in the US, time-resolved small-angle x-ray scattering (TRSAXS) is used to observe ultra-fast carbon clustering and graphite and nanodiamond production in the insensitive explosive Plastic Bonded Explosive (PBX) 9502, potentially leading to better computer models of explosive performance.

Infrastructure optimization tool from Sandia helps design future bases

DOE/Sandia National Laboratories
Business Announcement

Sandia National Laboratories has been helping the US Army identify the best equipment for temporary bases overseas since 2013. For the first time, a Sandia-designed software tool is being used to recommend the core set of equipment for bases to be built in 2020 and beyond.

Sandia develops optical diagnostic to help improve fuel economy while reducing emissions

DOE/Sandia National Laboratories
Peer-Reviewed Publication

A new optical device at Sandia National Laboratories that helps researchers image pollutants in combusting fuel sprays might lead to clearer skies in the future. An optical setup developed by researchers at Sandia's Combustion Research Facility and the Technical University of Denmark can now quantify the formation of soot -- particulate matter consisting primarily of carbon -- as a function of time and space for a variety of combustion processes.

Robotics principles help Sandia wave energy converters better absorb power of ocean waves

DOE/Sandia National Laboratories
Business Announcement

Compared to wind and solar energy, wave energy has remained relatively expensive and hard to capture, but engineers from Sandia National Laboratories are working to change that by drawing inspiration from other industries. Sandia's engineering team has designed, modeled and tested a control system that doubles the amount of power a wave energy converter can absorb from ocean waves, making electricity produced from wave energy less expensive.
