When spraying metal coatings, melting hurts rather than helps, MIT research reveals. When bonding two pieces of metal, either the metals must melt a bit where they meet or some molten metal must be introduced between the pieces. A solid bond then forms when the metal solidifies again. But researchers at MIT have found that
After demonstrating its ability to fire artillery rockets from decks of U.S. Navy ships, the U.S. Marine Corps now says it is interested in a similar, but super-compact mobile weapon system small enough to fit inside its MV-22B Osprey tilt-rotors or its future CH-53K King Stallion heavy lift helicopters. Such a vehicle would greatly increase
Whenever a new manufacturing machine is brought on line here, the first questions by visitors usually are: How much does the machine cost and what capability will it enhance? But with the latest installation of a hollow-spindle lathe, there might be a better question to ask — How much safer will the machine be for
The top equipment official for the Marine Corps recently said he believes that polymer is the answer to cutting ammunition weight for infantry squads. The Marines are focusing on lightening the load infantry squads carry into battle, William Williford, executive director of Marine Corp Systems Command, told an audience Monday at the Navy League’s Sea,
Perovskite solar cells promise cheaper and efficient solar energy, with enormous potential for commercialization. But even though they have been shown to achieve over 22{261f6ead6a0f3cabae584e9904bae8bd53a3c91c6c837aa2d58453541104ad2d} power-conversion efficiency, their operational stability still fails market requirements. Despite a number of proposed solutions in fabrication technology, this issue has continued to undercut whatever incremental increases in efficiency have
UNSW chemists have invented a new, cheap catalyst for splitting water with an electrical current to efficiently produce clean hydrogen fuel. UNSW chemists have invented a new, cheap catalyst for splitting water with an electrical current to efficiently produce clean hydrogen fuel. The technology is based on the creation of ultrathin slices of porous metal-organic
A team of researchers from the Georgia Institute of Technology has developed a way to use 3-D printers to create objects capable of expanding dramatically that could someday be used in applications ranging from space missions to biomedical devices. The new objects use tensegrity, a structural system of floating rods in compression and cables in
Neurotechnology is one of the hottest areas of engineering, and the technological achievements sound miraculous: Paralyzed people have controlled robotic limbs and computer cursors with their brains, while blind people are receiving eye implants that send signals to their brains’ visual centers. Researchers are figuring out how to make better implantable devices and scalp electrodes
Water could form the basis for future particularly inexpensive rechargeable batteries. Empa researchers have succeeded in doubling the electrochemical stability of water with a special saline solution. This takes us one step closer to using the technology commercially. In the quest to find safe, low-cost batteries for the future, eventually we have to ask ourselves
The most recent event in a series of coalition capability demonstrations is helping to ensure that equipment from NATO countries are able to work together, according to military officials from participating nations. John Miller, the event’s program manager assigned to the U.S. Joint Staff command and control, communications and computers/cyber directorate, told reporters during an
The Army has intensified the training soldiers receive on the FIM-92 Stinger — a man-portable, air defense missile — after nearly 15 years of moving away from the weapon system. The Stinger has been around since the late 1970s, according to the Army. As counterinsurgency became the Army’s primary mission focus, however, training drifted away
For the U.S. military to maintain its status as the greatest fighting force in the world, it must continue to learn and understand the multi-domain battlespace and significantly improve its operations across the entire range of military activity. It is widely believed that the U.S. military is exceptional and by far the best in the
