Major class of fracking chemicals no more toxic than common household substances

18-11-2014

The "surfactant" chemicals found in samples of fracking fluid collected in five states were no more toxic than substances commonly found in homes, according to a first-of-its-kind analysis by researchers at the University of Colorado Boulder. Fracking fluid is largely comprised of water and sand, ...

Self-powered herbicide biosensor

31-01-2013

A self-powered biosensor that can detect herbicides in water has been developed by US scientists. Most commercial herbicides act by inhibiting photosynthesis in plants. Unfortunately, photosynthetic aquatic microorganisms and aquatic plants are also similarly affected, which is why herbicides are ...

Scotch tape finds new use as grasping 'smart material'

26-11-2012

Scotch tape, a versatile household staple and a mainstay of holiday gift-wrapping, may have a new scientific application as a shape-changing "smart material." Researchers used a laser to form slender half-centimeter-long fingers out of the tape. When exposed to water, the four wispy fingers morph ...

Pyroelectric nanogenerator charges Li-ion battery with harvested energy

26-11-2012

The idea of harvesting ambient energy from the environment that would otherwise not be purposefully used is, in theory, a great way to produce green, renewable energy. But the biggest problem in this fairly new area of research is that scientists have yet to find a method that can harvest very ...
