White graphene can take the heat According to researchers at Rice University, 3D boron nitride structures excel at thermal management for electronics. Rice researchers Rouzbeh Shahsavari and Navid Sakhavand have completed the first theoretical analysis of how 3D boron nitride might be used as a tunable material to control heat flow in such devices. In its 2D form, hexagonal boron nitride... » read more

Optimizing algorithms Optimization algorithms try to find the minimum values of mathematical functions, and are everywhere in engineering for such things as evaluating design tradeoffs, assessing control systems, finding patterns in data, among other things. A way to solve a difficult optimization problem is to first reduce it to a related but much simpler problem, then gradually add complexit... » read more
