Chemistry World January 27, 2011 Laura Howes	Muons take kinetic isotope effects to extremes Scientists have used muons, elementary particles similar to electrons, to investigate the effect of isotope identity on one of the most fundamental reactions in chemistry.
Chemistry World January 26, 2011 Jon Cartwright	Luminescence gives 2D pH images Researchers in Germany have devised a safe method to image the pH of tissue in the human body. The method, which involves measuring the luminescence of injected dyes, could help physicians monitor wound healing and tumour growth.
Chemistry World January 26, 2011 Anna Watson	Channelling deeper to target breast cancer US scientists have developed a model of the breast ductal system that could be used to discover abnormal cells or deliver drugs at locations further along the ducts than other techniques. The model fits on a slide, enabling on-chip experiments.
Chemistry World January 21, 2011 Manisha Lalloo	Black TiO2 absorbs light across the spectrum Researchers in the US have used hydrogenation to introduce disorder into titanium dioxide nanocrystals, increasing the amount of solar light they absorb.
Chemistry World January 21, 2011 Russell Johnson	Jump starting prebiotic photochemistry Light activated reactions of organic molecules in fatty acid membranes offers a plausible method for energy transfer and storage in prebiotic systems, claim US scientists.
Chemistry World January 20, 2011 Jon Cartwright	Chemists separate water isomers Chemists in Israel claim to have separated water into its two spin isomers and suggest the outcome could deliver highly sensitive nuclear magnetic resonance experiments.
Chemistry World January 18, 2011 Philippa Ross	Pig power for batteries Scientists in China have developed an electrode for lithium-sulfur batteries using pig bones as a cheap and renewable carbon source.
Chemistry World January 14, 2011 Laura Howes	Size matters in piezoelectric materials Nanowires that produce current when bent and deformed can show huge improvements in efficiency as their diameters are shrunk. The findings will help advance research to power technology at the nanoscale.
Chemistry World January 13, 2011 Sarah Corcoran	Unclogging the problems of flow chemistry US scientists have found a way to stop solid byproducts clogging channels in continuous flow reactors, a problem that has hampered their progress for use in manufacturing pharmaceuticals.
Chemistry World January 12, 2011 Philip Ball	Einstein in your engine Rajeev Ahuja of Uppsala University in Sweden and his coworkers have looked at how relativistic effects on electron energies in lead atoms affect the voltage of the lead-acid battery, the standard electrical power source in cars.
