Worldwide race for Wonder material Graphene, in commercial, energy, aerospace and defence sectors

Graphene is a 1-atom-thick layer of tightly bonded carbon atoms arranged in a hexagonal lattice. Graphene the world’s first 2D nanomaterial, is widely regarded as the “wonder material” of the 21st century due to the combination of its extraordinary properties. As a single layer of graphite, it is the thinnest …

Molecular technologies enabling Molecular Robotics, the Ultimate Miniature Machines

The modern world is filled with macroscopic machines that perform work that we either find demanding or function in places or on length scales in which we cannot act. To date however, we have yet to develop a functional nanotechnology that operates on the scale of molecules or assemblies of …

Terahertz (THz) and Spintronics are converging to produce ultrafast THz sources

Terahertz (THz) waves lie in the electromagnetic spectrum between microwaves and infrared radiation. They are invisible to the human eye. Since they are low in energy, there is no need for be concerned with their impact on human. Today, they play a role in medical and communications technology, but also …

Nanotechnology enhancing compactness, efficiency, and performance, of Terahertz devices

In the past, the frequency spectrum ranging from 0.3 to 3THz (or 300 to 3000GHz) was spoken as infamous “Terahertz Gap” as it lies between traditional microwave and infrared domains but remained “untouchable” via either electronic or photonic means. The conventional “transit-time-limited” electronic devices can hardly operate even at its …

Columbia Engineers Revolutionize Augmented Reality (AR) Glasses through novel engineered optical materials (EnMats)

Imagine driving along the highway with directions and other pertinent information (think gas stations) appearing “on” your glasses so you ,don’t have to look away from the road. Or building a complicated DIY project with step-by-step instructions appearing “on” your glasses. Or being a first-responder unsure which way to go, …
