Isabella Karle, Renowned Crystallographer and Chemist, Dies at 95
October 24, 2017 — Dr. Isabella Karle, former U.S. Naval Research Laboratory (NRL) scientist and renowned crystallographer, died Oct. 3, 2017, at the age of 95 due to complications from a brain tumor... MORE

NRL Clarifies Valley Polarization for Electronic and Optoelectronic Technologies
October 19, 2017 — An interdisciplinary team of scientists at the U.S. Naval Research Laboratory (NRL) has uncovered a direct link between sample quality and the degree of valley polarization in monolayer transition metal dichalcogenides (TMDs). In contrast with graphene, many monolayer TMDs are semiconductors and show promise for future applications in electronic and optoelectronic technologies. ... MORE

International Team Observes First Radio Counterpart to Gravitational Waves
October 16, 2017 — Radio astronomers at the U.S. Naval Research Laboratory (NRL), Radio Astrophysics and Sensing Section, in collaboration with an international team from the Caltech-led Global Relay of Observatories Watching Transients Happen (GROWTH) project, measured the first ever detection of radio emission from colliding neutron stars nearly 124 million light years from Earth. The team discovered radio frequency emission in the range of 3 and 6 GHz in data taken Sept. 2 -3, 2017... MORE

NRL Receives US Patent for Carbon Capture Device: A Key Step in Synthetic Fuel Production from Seawater
October 3, 2017 — The world’s oceans cover approximately 70 percent of Earth’s surface and contain roughly 93 percent of the planet’s carbon dioxide (CO2). With around 38,000 gigatons (Gt) of carbon, our world’s oceans contain 16 times as much carbon as that found on land or in the atmosphere combined... MORE

The Great Years of Rath -- Materials Science & Component Technology Head Concludes 41-year Career at NRL
September 26, 2017 — Walk into Dr. Bhakta B. Rath’s office on a mid-August morning, and he welcomes you with a warm hello and handshake before settling in behind a desk piled unreasonably high with countless stacks of folders, documents, DoD correspondence and other paperwork requiring the attention of a man who leads more than 750 researchers and manages a $260 million budget...

Sediment Research is a Large, Yet Granular Exercise at NRL
August 18, 2017 — It’s an unseasonably warm February afternoon at the U.S. Naval Research Laboratory, Stennis Space Center (SSC), Mississippi, where three men are tinkering with a 7-foot tall, four-legged instrument platform, preparing it for an upcoming research experiment off the coast of Virginia...

NRL Brightens Perspective of Mysterious Mini-Halos
August 3, 2017 — The largest gravitationally bound objects in the universe are galaxy clusters that form at the intersection of cosmic web filaments. These entities are shaped and grow through massive collisions as material streams into their gravitational pull. Within the heart of some galaxy clusters are mysterious and little known radio mini-halos. These rare, dispersed, and steep-spectrum (brighter at low frequencies) radio sources surround a bright central radio galaxy and are highly luminous at radio wavelengths... MORE

New Phase Change Mechanism Could Lead to New Class of Chemical Vapor Sensors
July 24, 2017 — An interdisciplinary team of scientists at the U.S. Naval Research Laboratory (NRL) demonstrated that monolayer 2D Transition Metal Dichalcogenides (TMDs) — atomically thin semiconductors — undergo a change from semiconductor-to-metallic phase when exposed to airborne chemical vapors...
