Oyster Shells Inspire New Method to Make Superstrong, Flexible Polymers

Researchers at Columbia Engineering have demonstrated for the first time a new technique that takes its inspiration from the nacre of oyster shells, a composite material that has extraordinary mechanical properties, including great strength and resilience. By changing the crystallization speed of a polymer initially well mixed with nanoparticles, the team was able to control

Ultrafine Fibers Have Exceptional Strength

New technique developed at MIT could produce strong, resilient nanofibers for many applications. Researchers at MIT have developed a process that can produce ultrafine fibers — whose diameter is measured in nanometers, or billionths of a meter — that are exceptionally strong and tough. These fibers, which should be inexpensive and easy to produce, could

NRL Improves Optical Efficiency in Nanophotonic Devices

A team of physicists, headed by the U.S. Naval Research Laboratory (NRL), have demonstrated the means to improve the optical loss characteristics and transmission efficiency of hexagonal boron nitride devices, enabling very small lasers and nanoscale optics. “The applications for this research are considerably broad,” said Dr. Alexander J. Giles, research physicist, NRL Electronics Science
