Scientists develop new method to isolate atomic sheets and create new materials
Two-dimensional materials from layered van der Waals (vdW) crystals hold great promise for electronic, optoelectronic, and quantum devices, but making/manufacturing them has been limited by the lack of high-throughput techniques for exfoliating single-crystal monolayers with sufficient size and high quality.
Gas and water permeation barrier films play a vital part in applications ranging from food and pharmaceutical packaging to electronic devices. Two-dimensional (2D) materials, like graphene, are highly promising as ultra-high barrier materials, and their atomic thinness, mechanical stability, optical transparency and thermal properties offers many new possibilities and device form factors.

Read moreLasers are essential to many fields – ranging from optical communications and remote sensing, to manufacturing and medicine. While the semiconductor laser was first demonstrated nearly 60 years ago, advances in diode lasers and access to semiconductor fabrication techniques have enabled continued innovation and miniaturization of the technology.

Read moreSquids, octopuses and cuttlefish are undisputed masters of deception and camouflage. Their extraordinary ability to change color, texture and shape is unrivaled, even by modern technology.
Read moreThe terahertz frequency range – which sits in the middle of the electromagnetic spectrum between microwaves and infrared light — offers the potential for high-bandwidth communications, ultrahigh-resolution imaging, precise long-range sensing for radio astronomy, and much more.
Read moreA recent study from the labs of James Hone (mechanical engineering) and Cory Dean (physics) demonstrates a new way to tune the properties of two-dimensional (2D) materials simply by adjusting the twist angle between them. The researchers built devices consisting of monolayer graphene encapsulated between two crystals of boron nitride and, by adjusting the relative twist angle between the layers, they were able to create multiple moiré patterns.
Read moreBy folding snippets of DNA into the shape of a five-pointed star using structural DNA nanotechnology, researchers have created a trap that captures Dengue virus as it floats in the bloodstream. Once sprung, the trap – which is non-toxic and is naturally cleared from the body – lights up. It’s the most sensitive test for the mosquito-borne diseases yet devised.
