Danish EPA publishes survey on nanomaterials risks

The Danish Environmental Protection Agency (DEPA) has initiated the study "Survey on basic knowledge about exposure and potential environmental and health risks for selected nanomaterials". The objective of the study is to provide an overview of the applications of the most commonly used or widespread nanomaterials and to identify areas most likely to have health or environmental problems associated with their use.

Researchers describe how to efficiently merge microdroplets using electric field

In microfluidic devices, small separated droplets flow in a stream of carrier liquid. Occasionally, selected droplets have to be merged to carry out a chemical reaction. This can be greatly facilitated with the use of electric field, through a process of electrocoalescence that has been used industrially in large scale applications. Researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences have found the laws governing the process and how to maximise the efficiency of merging.
