Develop new model to predict optical properties of nanostructures

University of British Columbia chemists have developed a new model to predict the optical properties of non-conducting ultra-fine particles. The finding could help inform the design of tailored nano-structures, and be of utility in a wide range of fields, including the remote sensing of atmospheric pollutants and the study of cosmic dust formation.

Study analyses the possibilities and bottlenecks for regulating nanomaterials with uncertain risks

The study examines the possibilities and limitations for such regulation under existing legislation covering the environment, consumer protection and occupational health and safety, given the uncertain risks attached to the use of nanomaterials. The central research question is which powers authorities hold to regulate production, processing, use and the waste phase of nanomaterials (and products containing them) and the obligations that companies have to assure the safety of man and the environment.

Electro-osmotic pump simplifies home diagnostics

Researchers in Sweden have invented an improved pump, called an electroosmotic pump, which can be placed in a "microfluidic chip". Such chips, sometimes called "lab-on-a-chip" devices, contain miniaturized versions of the beakers and test tubes found in chemistry laboratories interconnected by tiny pipes. Rather than using moving parts, the new pump moves fluids in these pipes via an electric current. The fluids to be pumped can be biological samples such as blood, urine or saliva for medical devices.
