Consider the 'anticrystal'

(Phys.org) —For the last century, the concept of crystals has been a mainstay of solid-state physics. Crystals are paragons of order; crystalline materials are defined by the repeating patterns their constituent atoms and ...

Adding a carbon atom transforms 2-D semiconducting material

A technique that introduces carbon-hydrogen molecules into a single atomic layer of the semiconducting material tungsten disulfide dramatically changes the electronic properties of the material, according to Penn State researchers ...

Blight-resistant American chestnut trees nearing reality

(PhysOrg.com) -- The demise of the American chestnut is one of the great ecological disasters of our time, according to a chestnut expert in Penn State's College of Agricultural Sciences, who envisions a day in the not-so-distant ...

Personal cooling units on the horizon

Firefighters entering burning buildings, athletes competing in the broiling sun and workers in foundries may eventually be able to carry their own, lightweight cooling units with them, thanks to a nanowire array that cools, ...

New class of materials shows strange electron properties

A method to observe a new class of topological materials, called Weyl semimetals, was developed by researchers at Penn State, MIT, Tohoku University, Japan and the Indonesian Institute of Sciences. The material's unusual ...
