A Graphene Superconductor That Plays More Than One Tune

superconductivity in a trilayer graphene moiré superlattice

Researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a graphene device that’s thinner than a human hair but has a depth of special traits. It easily switches from a superconducting material that conducts electricity without losing any energy, to an insulator that resists the flow of electric current, …

Programmed Nanorobots Seek And Destroy Cancer Tumors

nanorobots

Nanorobots have been successfully programmed to shrink tumors by cutting off their blood supply. This major advancement came from Arizona State University (ASU) scientists, in collaboration with researchers from the National Center for Nanoscience and Technology (NCNST), of the Chinese Academy of Sciences. The demonstration of the technology, the first-of-its-kind study in mammals, used breast …

DNA Nanorobots Pick Up And Sort Molecules

dna nanorobot

An autonomous molecular machine, made of a single strand of DNA, that can autonomously “walk” around a surface, pick up certain molecules and drop them off in designated locations has been developed by scientists at California Institute of Technology. Lulu Qian, assistant professor of bioengineering, explains: “Just like electromechanical robots are sent off to faraway …

Carbon Dioxide Absorption By Boron Nitride Foam

boron nitride foam

A light foam created from two-dimensional sheets of hexagonal boron nitride by materials scientists at Rice University absorbs carbon dioxide. They discovered freeze-drying hexagonal-boron nitride (h-BN) transformed it into a macro-scale foam that disintegrates in liquids. But adding a bit of polyvinyl alcohol (PVA) into the mix turned it into a far more robust and …

Photonic Crystals Self-Assembled From Colloidal Particles

Pyrochlore

Scientists have worked for decades to get colloidal spheres to arrange themselves in sparser lattices, which would unleash potentially valuable optical properties. The structures, called photonic crystals, could increase the efficiency of lasers, make optical components even smaller, and increase engineers’ ability to control the flow of light. Now, New York University researchers report a …
