Researchers at City University of Hong Kong have observed high elasticity and defect tolerance in "white graphene," or hexagonal boron nitride. Also known as h-BN, the two-dimensional material has many of the qualities of regular graphene, but its additional robustness holds potential in strain engineering, piezoelectronics and flexible electronics.
Wearing personal protective equipment for an extensive time can irritate the skin, and typical skin lotions don't provide much relief. However, help is at hand in the form of absorption-resistant lubricants such as mixtures of coconut oil, cocoa butter and beeswax and powders like talcum, according to research at Imperial College London.
A 4D imaging radar system for autonomous vehicles is being developed by Continental and processor specialist Xilinx. The system, which will begin showing up in production vehicles next year, will be able to detect an object's relative speed, elevation, direction and range in any weather or lighting condition.
The USS Nimitz has become the first US aircraft carrier to operate in the Persian Gulf since the USS Abraham Lincoln left in November 2019. The Nimitz and its strike group will provide air support for the ongoing Operation Inherent Resolve.
The guided-missile cruiser USS Antietam successfully hit a target during a simulated Tomahawk cruise missile attack in the Valiant Shield 2020 exercise off the coast of Guam. The exercise demonstrated the cruiser's ability to "track, target, and engage threats to protect peace and stability in the Indo-Pacific," the Navy said.
BAE Systems will build Archerfish mine neutralizers for the US Navy under a $110.94 million contract. The seven-year deal also covers fiber optic spool kits, support equipment, surveys, repairs and program management and support.
Newport News Shipbuilding will carry out an engineering overhaul of the Los Angeles-class submarine USS Boise under a $351.8 million contract modification. Exercised options would raise the contract value to $355 million.
