Chemistry World November 7, 2012 Simon Hadlington	World's first all-carbon solar cell Researchers in the US and China have built a photovoltaic cell made entirely from carbon. The electrodes and light-active layers are made from a combination of three carbon allotropes -- nanotubes, fullerenes and graphene.
Chemistry World November 7, 2012 Ian Le Guillou	Coral animal chemical structures solved A combination of atomic force microscopy and computational techniques have been used to solve the unusual structures of two natural products from the Arctic coral-like animal, Thuiaria breitfussi.
Chemistry World October 31, 2012 Ian Le Guillou	A cell for a cell If you ever need to isolate a single bacterial cell, why not build it a prison cell? This is the approach that colleagues from Sandia National Laboratories, US, have taken. Using multi-photon lithography, they can construct four walls and a roof around a single cell in just over a minute.
Chemistry World October 31, 2012 James Mitchell Crow	Nitrogen does diamond Nitrogen will form an unusual cage-like structure when subjected to high pressures, an international team of researchers has calculated.
Chemistry World October 31, 2012 Andrea Sella	Penning's vacuum gauge Frans Michel Penning's gauge harnessed the phenomenon of electrical discharge in gases to measure ultra-low pressure vacuums.
Chemistry World October 30, 2012 Helen Gray	Cardboard to create current from bacteria Researchers in Germany and China have discovered that cheap corrugated cardboard makes a high-performing electrode for microbial fuel cells, a key technology for sustainable energy production.
Chemistry World October 29, 2012 James Urquhart	Fireflies inspire low-cost LED lighting Colleagues at the Korea Advanced Institute of Science and Technology have examined the intricate nanostructure of the firefly's lantern cuticle and created an artificial version for use as a high-power LED lens.
Chemistry World October 28, 2012 Simon Hadlington	MOF based motorboat Researchers have devised a new type of molecular motor capable of propelling itself across a liquid surface. The move mimics motile life forms found in nature, such as bacteria, in the quest for autonomous microscopic machines.
Chemistry World October 26, 2012 Andy Extance	Molecular muscle machines bulk up French researchers have made the longest molecular machines that can be shrunk on demand in a collective motion that emulate muscle fibers.
Chemistry World October 25, 2012 Rebecca Brodie	Energy harvesting from your phone display What if you could harness some of that wasted energy from your smartphone and put it back into the phone's battery? A group of scientists from Massachusetts Institute of Technology in the US have done just that.
