The future viability of renewable energy sources may depend on the ability to store and then use surplus energy, and metals heated to extremely high temperatures is seen as one solution. Pumping molten metals safely is the object of research by professor Asegun Henry and his team at Georgia Tech's Woodruff School of Mechanical Engineering, where they're working on a ceramic pump that can move molten tin heated to 1,600 kelvins.
Biomedical engineers at Texas A&M University are using seaweed and clay in the form of nanoflakes to develop an injectable bandage. The resulting hydrogel product could be a quick way to address severe internal bleeding that occurs near vital organs where applying pressure is impossible.
Using the Continuous Electron Beam Accelerator Facility, scientists at Virginia's Thomas Jefferson National Accelerator Facility have managed to calculate the pressure inside a proton. And it's 10 to the 30th power times the air pressure at sea level, or an order of magnitude greater than the pressure in a neutron star, one of the densest known objects.
Grades and experience provide little insight into an engineering student's motivation, a key factor in their success. Peter Rogers, a mechanical engineer and a professor of practice in the Ohio State University's engineering education department, is developing surveys and assessment tools that hone in on this intrinsic measure.
The Bahrain-based, US-led Combined Maritime Forces have completed 12 days of anti-piracy drills in the Gulf of Aden. Seven nations participated in the exercise, which involved interactions with regional fishing vessels and dhows.
The first of the Navy's Flight III destroyers is under construction. The ship, due for delivery in 2024, will differ from the Arleigh Burke class in important ways, notably with the inclusion of Raytheon's AN/SPY-6 air and missile defense radar.
Vigor Marine will perform routine repairs and updates for the destroyer USS Sampson under a $42.2 million dry-dock contract. Work may include surface prep and painting as well as work on the freeboard, struts, rudders, hull and electric infrastructure.
After more than six years deployed in the western Pacific, the amphibious assault ship USS Bonhomme Richard has returned home to San Diego. The vessel, which was the Navy's only forward-deployed ship of its kind in the region, has since been relieved by the USS Wasp.
An additional Ford-class aircraft carrier and a 2.6% pay increase for troops are part of the fiscal 2019 defense bill approved by the House Armed Services Committee. Roxana Tiron gives a rundown of what's in the legislation, including funds for a military parade.
