How “2D” Materials Expand

A new technique that accurately measures how atom-thin materials expand when heated could help engineers develop faster, more powerful electronic devices. Two-dimensional materials, which consist of just a single layer of atoms, can be packed together more densely than conventional materials, so they could be used to make transistors, solar cells,

This little Robot Ready For Any Obstacle

This little robot can go almost anywhere. Researchers at Carnegie Mellon University's School of Computer Science and the University of California, Berkeley, have designed a robotic system that enables a low-cost and relatively small legged robot to climb and descend stairs nearly its height; traverse rocky, slippery, uneven, steep and varied
