Researchers confirm reptation theory of polymer behavior, showing hot chains coil back and snap forward, leaving a telltale signature. The study suggests stronger composite materials and welded plastic seams, with potential applications in aircraft, medical devices, and consumer products.
A University of Colorado at Boulder chemical engineering team has developed new techniques for faster healing of severe bone fractures and regeneration of cartilage in joints. The process uses ultraviolet light to create custom scaffolds that can be engineered to time-release medications and human-growth factors.
A recent study highlights the importance of delivering bad news effectively to patients with cancer and other serious illnesses.
