They've been called 'dream' plastics: polyhydroxyalkanoates, or PHAs. Already the basis of a fledgling industry, they're a class of polymers naturally created by living microorganisms, or synthetically produced from biorenewable feedstocks. They're biodegradable in the ambient environment, including oceans and soil.

Twisted molecules play an important role in the development of organic light-emitting diodes. A team of chemists has managed to create these compounds with exactly the three-dimensional structure that they wanted. In so doing, they are smoothing the path for new and better light sources.

Single-use hard plastics are all around us: utensils, party decorations and food containers, to name a few examples. These items pile up in landfills, and many biodegradable versions stick around for months, requiring industrial composting systems to fully degrade. Now, researchers have created a sturdy, lightweight material that disintegrates on-demand -- and they made it from sugar and wood-derived powders.

Researchers introduce a novel imaging method to detect gold nanoparticles in woodlice. Their method, known as four-wave mixing microscopy, flashes light that the gold nanoparticles absorb. The light flashes again and the subsequent scattering reveals the nanoparticles' locations. With information about the quantity, location, and impact of gold nanoparticles within the organism, scientists can better understand the potential harm other metals may have on nature.

In an advance they consider a breakthrough in computational chemistry research, chemical engineers have developed a model of how catalytic reactions work at the atomic scale. This understanding could allow engineers and chemists to develop more efficient catalysts and tune industrial processes -- potentially with enormous energy savings, given that 90% of the products we encounter in our lives are produced, at least partially, via catalysis.

A recently discovered catalyst, can convert carbon dioxide (CO2) into useful methanol at room temperature and low-pressure conditions. This novel compound, which is thermally and chemically stable in air, represents a new milestone in CO2 conversion via hydrogenation and could be key to slow down climate change.

Researchers have developed a new way to produce and shape large, high-quality mirrors that are much thinner than the primary mirrors previously used for telescopes deployed in space. The resulting mirrors are flexible enough to be rolled up and stored compactly inside a launch vehicle and then reshaped after deployment.
