A nanophenomenon that triggers the bone-repair process

Researchers of the ICN2 Oxide Nanophysics Group led by ICREA Prof. Gustau Catalan have resolved one of the great unknowns in bone remodelling: how the cells responsible for forming new bone tissue are called into action. Their work reveals...Show More Summary

Fast computer control for molecular machines

Scientists at the Technical University of Munich (TUM) have developed a novel electric propulsion technology for nanorobots. It allows molecular machines to move a hundred thousand times faster than with the biochemical processes used to date. Show More Summary

Atomically resolving images of beam-sensitive materials using transmission electron microscopy

Staff members at King Abdullah University of Science and Technology (KAUST) have devised a methodology for the procurement of atomically resolved images of beam-sensitive materials using transmission electron microscopy. They published their findings as a first release in Science on January 18, 2018.

Inspired by biology, scientists created new tiny tubes that could help with water purification and tissue engineering

Materials scientists, led by a team at the Department of Energy's Pacific Northwest National Laboratory, designed a tiny tube that rolls up and zips closed.

Study reveals secrets of 'fluid-like' heat flow in solid semiconductor at nanoscale

Researchers are applying the same "hydrodynamic transport model" used to study flow in fluids to explain heat transport in a solid semiconductor, with potential implications for the design of high-speed transistors and lasers.

Metal nanoparticles for imaging guided phototherapy

National University of Singapore chemists have recently discovered that gold-silver (Au-Ag) nanoparticles can be used to image and provide concurrent treatment for bacterial infections.

Ultra-thin memory storage device paves way for more powerful computing

Engineers worldwide have been developing alternative ways to provide greater memory storage capacity on even smaller computer chips. Previous research into two-dimensional atomic sheets for memory storage has failed to uncover their potential—until now.

Nanowrinkles could save billions in shipping and aquaculture

A team of chemistry researchers from the University of Sydney Nano Institute has developed nanostructured surface coatings that have anti-fouling properties without using any toxic components.

Physicists measure mechanical properties of 2-D monolayer materials

The thinnest materials that can be produced today have the thickness of a single atom. These materials – known as two-dimensional materials – exhibit properties that are very different compared with their bulk three-dimensional counterparts. Show More Summary

Solid and liquid at the same time

Microscopically small particles can spontaneously self-assemble into complex layered structures with remarkable properties, according to calculations performed at the TU Wien.

Scientists synthesize nanoparticle-antioxidants to treat strokes and spinal cord injuries

An international science team has developed an innovative therapeutic complex based on multi-layer polymer nanostructures of superoxide dismutase (SOD). The new substance can be used to effectively rehabilitate patients after acute spinal injuries, strokes, and heart attacks.

Researchers reveal high performance CNT catalyst relating to its electroconductivity

Recent research published in a report in Nano showed biofuels were obtained from Jatropha Oil using carbon nanotube (CNT) catalyst, which showed efficient cracking activity. The performance was activated by the high stability, metal sites, acid sites, electroconductivity, and coking tolerance of CNT. Show More Summary

From flagship to spaceship—two experiments pushing the frontier of graphene's potential
