Nanoscale insights could lead to improved nuclear reactors

In order to build the next generation of nuclear reactors, materials scientists are trying to unlock the secrets of certain materials that are radiation-damage tolerant. Now researchers at the California Institute of Technology (Caltech) have brought new understanding to one of those secrets - how the interfaces between two carefully selected metals can absorb, or heal, radiation damage.

Charakterisierung von nanoskaligen Eigenschaften chemischer Stoffe unter REACH

Die Bundesanstalt für Arbeitsschutz und Arbeitsmedizin (BAuA) hat den Forschungsauftrag zur "Charakterisierung von nanoskaligen Eigenschaften chemischer Stoffe als Grundlage für die Regulierung im Rahmen der Verordnung (EG) Nr. 1907/2006 (REACH)" vergeben. Der jetzt veröffentlichte Endbericht zeigt, wie sich die für die REACH-Verordnung geltenden physikalisch-chemischen Prüfnachweise auf Nanomaterialien anwenden lassen.

Optical microscopes lend a hand to graphene research

The remarkable properties and subsequent applications of graphene have been well-documented since it was first isolated in 2004; however, researchers are still trying to find a quick, cheap and efficient way of measuring its thickness. A group of researchers from China appear to have solved this problem by devising a universal method using just a standard optical microscope.

New injectable gels toughen up after entering the body

Gels that can be injected into the body, carrying drugs or cells that regenerate damaged tissue, hold promise for treating many types of disease, including cancer. MIT chemical engineers have now designed an injectable gel that responds to the body's high temperature by forming a reinforcing network that makes the gel much more durable, allowing it to function over a longer period of time.

Invisible man achieved using invisibility cloak technology (w/video)

Fractal Antenna Systems today disclosed that it has successfully rendered a man invisible. The firm's new invisibility cloak hid a man at microwaves over a wide bandwidth at high fidelity. This is the first time any large object has been rendered invisible and the first time a person has disappeared from view using invisibility cloak technology.

Physicists skirt thermal vibration, transfer optical signal via mechanical oscillator

Using tiny radiation pressure forces - generated each time light is reflected off a surface - University of Oregon physicists converted an optical field, or signal, from one color to another. Aided by a "dark mode", the conversion occurs through the coupling between light and a mechanical oscillator, without interruption by thermal mechanical vibrations.

Wax-filled nanotechnology yarn behaves like powerful, super-strong muscle (w/ Video)

New artificial muscles made from nanotech yarns and infused with paraffin wax can lift more than 100,000 times their own weight and generate 85 times more mechanical power than the same size natural muscle, according to scientists at The University of Texas at Dallas and their international team from Australia, China, South Korea, Canada and Brazil.
