Researchers
at the Virginia Institute of Marine Science are investigating whether
sound waves can be used to determine the size of oil droplets in the
subsea—knowledge that could help guide the use of chemical dispersants
during the cleanup of future spills.

For Tim Gutowski, advanced manufacturing is an opportunity not just to boost employment, but also to improve the environment. Gutowski heads Massachusetts Institute of Technology's Environmentally Benign Manufacturing research group, which looks at the environmental costs and impacts associated with manufacturing traditional materials, as well as advanced and emerging technologies.

While the costs associated with storing nuclear waste and the possibility of it leaching into the environment remain legitimate concerns, they may no longer be obstacles on the road to cleaner energy. A recent paper showcases Thorium Borate-1 as a crystalline compound that can be tailored to safely absorb radioactive ions from nuclear waste streams.

A
research group in Japan have synthesized graphene by reducing graphene
oxide using microorganisms extracted from a local river. The method was
inspired by a recent report showing that graphene oxide behaves as a
terminal electron acceptor for bacteria.

A project from a team of researchers from Imperial College London, the University of Manchester, and Durham University beat more than 2,000 other proposals to receive funding from the Bill and Melinda Gates Foundation to develop a prototype system for recovering drinkable water and harvesting hydrogen energy from human faecal waste.

Scientists at Tufts University have found a way to create a selective hydrogenation catalyst by scattering single atoms of palladium onto a copper base. The catalyst requires less of the expensive metal, and the process is greener, too, offering potentially significant economic and environmental benefits.

NIST has released a new certified reference material to support the federal government's Natural Resources Assessment (NRDA) in the wake of the April 2010 Deepwater Horizon oil spill 40 miles off the Louisiana coast. The material will be used as a quality control material for the ongoing environmental impact analyses for the NRDA effort.

Amalgams,
which are alloys of mercury and other metals, have been used for over
2,500 years in the production of jewelry and for the extraction of
metals like silver and gold in mining operations. These days, the
inverse process is of greater interest: the removal of mercury from
wastewater by amalgamation with precious metals in the form of
nanoparticles.

High-level
spectroscopy and computer simulations of specially diluted liquids are
gradually revealing the long-debated structure of air-water interfaces.
At RIKEN in Japan, specialized techniques such as vibrational sum
frequency generation are being used to examine this medium, which is
notoriously difficult to study.

A Colorado State University chemistry professor has
developed several patent-pending chemical processes that would create
sustainable bioplastics from renewable resources for use on everything
from
optical fibers and contact lenses to furniture and automobile parts.
