A breakthrough in materials could improve the efficiency and effectiveness of electronic implants in the human brain or other parts of the body. The advance could offer an array of biotechnology benefits and allow humans to control unmanned vehicles and other technologies directly with their brains.

The development involves a polythiophene, or PEDOT, chemical structure. The newest materials, which David Martin describes as PEDOT Plus, dramatically enhances electronic implants in the body.

Nanotechnology continues its march through the field of electronics, enabling faster and more energy-efficient computer processors, larger computer memory density and increased battery capacity. These ever-shrinking micro and nanodevices require advanced manufacturing methods to produce. Atomic-scale processing refers to a collection of these methods that may be used to deposit and remove material at the smallest scales, a single atomic layer at a time.

University of Connecticut, Storrs, Connecticut, has been awarded a $7,953,698 cost-reimbursement contract for research in the area of developing capabilities to predict performance of aerospace materials in the manufacturing environment as well as when subjugated to extreme thermomechanical influences. Work will be performed in Storrs, Connecticut, and is expected to be completed by November 7, 2023. Fiscal year 2019 research, development, test and evaluation funds in the full amount are being obligated at the time of award. Air Force Research Laboratory, Wright-Patterson Air Force Base, Ohio, is the contracting activity (FA8650-20-C-5206).

A composite metal foam (CMF) material developed by researchers at North Carolina State University can stop ball and armor-piercing .50 caliber rounds as well as conventional steel armor, even though it weighs less than half as much, the university recently announced. The finding means that vehicle designers will be able to develop lighter military vehicles without sacrificing safety, or can improve protection without making vehicles heavier.

Previous research has resulted in CMF material capable of shredding bullets.
