Moving from science fiction to reality: chemically driven micro- and nanomotors

In this review article, scientists present the current state of research in the area of catalytic micro- and nanomotors.

Silver particles improve performance of battery material

Researchers are working on a new battery architecture that uses lithium-oxygen bonds as it stores and releases energy and silver as the metal catalyst that makes this possible.

New law for superconductors

Mathematical description of relationship between thickness, temperature, and resistivity could spur advances.

Scientist and inventor advances the study of nanomedicine

For distinguished contributions to the fields of chemistry, radiopharmaceutical sciences, green nanotechnology and nanomedicine, Kattesh Katti has been chosen for induction as a Fellow of the National Academy of Inventors.

Turning hydrogen into graphene

New work delves into the chemistry underlying some surprising recent observations about hydrogen and reveals remarkable parallels between hydrogen and graphene under extreme pressures.

Scientists trace nanoparticles from plants to caterpillars

A new study examines how nanoparticles behave in food chain.

Future batteries: lithium-sulfur with a graphene wrapper

Scientists have designed a novel cathode for rechargeable lithium-sulfur batteries featuring a thin 'wrap sandwich' sheet of graphene.

Imaging a single DNA molecule with a smartphone

Lightweight, compact device converts an ordinary smartphone into an advanced fluorescence microscope.

Line dancing bacteria on a chip (w/video)

By changing the direction of a magnetic field, so-called magneto-tactic bacteria are able to make a full U-turn. They can be taught line dancing in this way, inside the tiny micro channels of a lab on a chip.

Waves, folds and plastic flow: detecting the first signs of wear on metal surfaces

Researchers show which wear mechanisms take place on metal surfaces before the actual wear becomes apparent. Understanding such mechanisms is the first step to minimizing friction and wear.

Broadband graphene optical modulator on silicon

10Gb/s Graphene optical electro-absorption modulator outperforms state-of-the-art SiGe modulators.

Researchers create 'green' process to reduce molecular switching waste

Researchers have found a solution using visible light to reduce waste produced in chemically activated molecular switches, opening the way for industrial applications of nanotechnology ranging from anti-cancer drug delivery to LCD displays and molecular motors.

Self-repairing subsea material

Embryonic faults in subsea high voltage installations are difficult to detect and very expensive to repair. Researchers believe that self-repairing materials could be the answer.

New findings could point the way to 'valleytronics'

Researchers clear hurdles toward a new kind of 2-D microchip using different electron properties.
