A team of Penn State electrical engineers have a way to simultaneously control diverse optical properties of dielectric waveguides by using a two-layer coating, each layer with a near zero thickness and weight.
Now a team of Penn State engineers have a different type of lithium sulfur battery that could be more efficient, less expensive and safer.
Every culture on the planet has its ways of producing, using and communicating through its fabrics.
A theoretical method to control grain boundaries in two-dimensional materials could result in desirable properties, such as increased electrical conductivity, improved mechanical properties, or magnetism for memory storage or information processing, among other applications.
