A process for engineering next-generation soft materials with embedded chemical networks that mimic the behavior of neural tissue lays the foundation for soft active matter with highly...
Briefs: Electronics & Computers
Photons, or units of light, are faster than electrons and could, therefore, process information faster from smaller chip structures. A switch was designed that bypasses a...
Briefs: Photonics/Optics
Optical fibers have been traditionally produced by making a cylindrical object called a preform — essentially, a scaled-up model of the fiber — and then heating it. Softened material...
Briefs: Photonics/Optics
Computer processors have continued to shrink down to nanometer sizes where there can be billions of transistors on a single chip. This phenomenon is described under Moore's Law, which...
