Chemistry World July 5, 2010 Jon Cartwright	Imaging technique sees conversion of biomass to sugar The technique, called stimulated Raman scattering microscopy, is better than others because it can give quantitative readings of the species present.
Chemistry World July 4, 2010 Hayley Birch	DNA sticks at flick of switch A new technique that sticks individual DNA molecules to a gold surface works at the flick of an electrochemical switch.
Chemistry World June 27, 2010 Simon Hadlington	Nanoparticles allow remote control of cells In an experiment reminiscent of the mind-control rays that featured prominently in B-movies from the 1950s, scientists in the US have used a magnetic field to alter the behavior of an animal.
Chemistry World June 25, 2010 Phillip Broadwith	Molecular machines shift into gear A set of molecular gears based on porphyrin complexes that can be chemically engaged and disengaged using acid or base has been created by Japanese researchers.
Chemistry World June 24, 2010 Mike Brown	Movies of molecules in 4D Movies of carbon nanotube bracelets showing their response over time to an external trigger have been recorded enabling greater understanding of not only the 3D structure of the nanotubes, but of how they react and move, say scientists in the US.
Chemistry World June 23, 2010 Simon Hadlington	New catalyst for hydrogen from formic acid Chemists in Germany have taken a leaf out of nature's book to develop a new, low-cost, iron-based catalyst powered by light that can extract hydrogen from formic acid.
Chemistry World June 22, 2010 Andy Extance	Powering up organic solar cells Organic molecules combining aromatic, lipophilic and hydrophilic segments can organise themselves into structures with five times the photoconductivity of structures like those typically adopted by aromatic groups alone.
Chemistry World June 20, 2010 Jon Cartwright	Carbon nanotubes boost battery power Researchers in the US claim to have created electrodes from carbon nanotubes that can make lithium-ion batteries some ten times more powerful than conventional models.
Chemistry World June 17, 2010 Hayley Birch	Keeping the heat up for super-efficient solar cells US scientists have found a way to siphon off the 'hot' electrons that are responsible for much of the energy lost in current solar cells.
Chemistry World June 16, 2010 Simon Hadlington	Rotaxane molecule seen in action Researchers from the US and Japan have directly observed the ring of a rotaxane molecule shuttling along its spindle. The behaviour of the rotaxane is influenced by its molecular environment, something that is significant if the molecules are to be used as molecular machines.
