Environmental toxins enter the brain tissue of polar bears

PerFluoroAlkyl Substances (PFASs) and precursor compounds have been used in a wide variety of commercial and industrial products over the past six decades. Applications include water and oil repellent coatings, e.g. for textiles, ...

Sniffing out new repellents: Why mozzies can't stand the DEET

The smell of mozzie repellent is as much a part of summer as barbecues and the cricket. Despite supermarket and pharmacy shelves overflowing with insect repellents, there are actually only a few active ingredients to be found ...

Researchers compare 'natural' mosquito repellents to DEET

Discovery could lead to new way of cleaning up oil spills

(Phys.org) —University of Alberta mechanical engineering researchers have shown that a simple glass surface can be made to repel oil underwater. This has huge implications for development of a chemical repellent technology ...

New research finds graphene can act as surfactant

New research into graphene flakes has discovered that the material can act as a surfactant, for the first time demonstrating how it can be a versatile 2-D stabiliser ideal for many industrial applications from oil extraction ...
