Shocking results from diamond anvil cell experiments

At first, nanoshocks may seem like something to describe the millions of aftershocks of a large earthquake. But Lawrence Livermore National Laboratory physicists are using an ultra-fast laser-based technique they dubbed 'nanoshocks' for something entirely different. In fact, the nanoshocks have such a small spatial scale that scientists can use them to study shock behavior in tiny samples such as thin films or other systems with microscopic dimensions.

Study measures single-molecule machines in action

A multidisciplinary team of researchers from UCLA, Northwestern University, UC Merced, Pennsylvania State University and Japan has succeeded in observing single-molecule interactions of bistable rotaxanes functioning in their native environment.

Nanoscale plasmonic motor drives micro-sized disk

While those wonderful light sabers in the Star Wars films remain the figment of George Lucas' fertile imagination, light mills - rotary motors driven by light - that can power objects thousands of times greater in size are now fact. Researchers have created the first nano-sized light mill motor whose rotational speed and direction can be controlled by tuning the frequency of the incident light waves.

European Commission publishes reference report on definition of nanomaterials for regulatory purposes

Despite the growing utilisation of engineered nanomaterials in consumer products and innovative technological applications, there is at present no widely accepted definition of the term "nanomaterial" that is suitable as a basis for legislation on their safe use. Responding to a request of the European Parliament, the Joint Research Centre (JRC) published today a reference report entitled 'Considerations on a definition of nanomaterial for regulatory purposes".

Protein mit doppeltem Lichtschalter

Ein neues fluoreszentes Markerprotein haben Forscher um Professor Gerd Ulrich Nienhaus vom KIT entwickelt: Bei dem photoaktivierbaren Protein 'mIrisF'" laesst sich sowohl das Fluoreszenzlicht ein- und ausschalten als auch die Farbe des Lichts von Guen nach Rot veraendern.

Characterisation and engineering of protein-carbohydrate interactions

Protein-carbohydrate interactions play a crucial role in many biological processes such as cell-cell recognition and receptor-ligand interactions and catalysis. This thesis explores the possibilities of engineering the protei-carbohydrate interactions between carbohydrate-binding proteins and their ligands.
