Researchers have explored how carbon moves between Earth's interior, surface and atmosphere; how much deep carbon exists, in what forms (including vast microbial life); where carbon came from; and how life began.
Read moreNew research describes the mechanism behind catalysis that neutralizes air-polluting NOx from power plant emissions. Researchers used a High Field (HF) Nuclear Magnetic Resonance (NMR) spectrometer in conjunction with reaction studies to test three theories around titania-supported vanadium oxide. They found that tungsten oxide changes the structure of vanadium oxide from a less active form to a highly active form.
Read moreResearchers have built a self-assembled nanocage with a very unusual nanospace: Its walls are made of antiaromatic molecules, which are generally considered too unstable to work with. By overturning assumptions about the limits of nano-chemical engineering, the study creates an entirely new nanospace for scientists to explore. Nanometer-sized cavities are already finding a range of useful applications in chemistry, medicine and environmental science.
Read moreSpin-polarizing scanning tunneling microscopy allowed researchers to detect an elusive atomic-scale magnetic signal in a Mott insulator, reports a team of scientists.
Read moreScientists demonstrate a new approach in fluorescence microscopy that can be used to locate individual biomolecules in 3D space with nanometer-scale precision.
Read moreResearchers have succeeded in creating an efficient quantum-mechanical light-matter interface using a microscopic cavity. Within this cavity, a single photon is emitted and absorbed up to 10 times by an artificial atom. This opens up new prospects for quantum technology.
Read moreClay minerals suspended in seawater binds sedimentary organic carbon to their mineral surfaces. But the quantity of carbon that is bound and the source of that carbon very much depends on the clay mineral in question. A research team has shown this by studying sediments in the South China Sea.

A widely-used gas that is currently produced from fossil fuels can instead be made by an 'artificial leaf' that uses only sunlight, carbon dioxide and water, and which could eventually be used to develop a sustainable liquid fuel alternative to gasoline.
A quantum gas can be tied into knots using magnetic fields. The same researchers who were the first to produce these knots have now studied how the knots behave over time. The surprising result is that the knots untie themselves over a short period of time, before turning into a vortex.
Read moreThe identification of new chemical bonds is crucial for the design of new material structures. A team has found unexpected new configurations of oxygen and nitrogen in graphene.
