| Soft spheres settle in somewhat surprising structure Posted: 24 Jul 2011 10:55 AM PDT Latex paints and drug suspensions such as insulin or amoxicillin that do not need to be shaken or stirred may be possible thanks to a new understanding of how particles separate in liquids, according to chemical engineers, who have developed a method for predicting the way colloidal components separate based on energy.  |
| New photonic crystals have both electronic and optical properties Posted: 24 Jul 2011 10:55 AM PDT In an advance that could open new avenues for solar cells, lasers, metamaterials and more, researchers have demonstrated the first optoelectronically active 3-D photonic crystal.  |
| Pocket chemistry: DNA helps glucose meters measure more than sugar Posted: 24 Jul 2011 10:55 AM PDT Glucose meters aren't just for diabetics anymore. Thanks to a team of chemists, they can be partnered with functional DNA sensors as simple, portable, inexpensive meters for a number of target molecules in blood, serum, water or food. The researchers demonstrated using functional DNA with glucose meters to detect cocaine, the disease marker interferon, adenosine and uranium. The two-step method could be used to detect any kind of molecule that a functional DNA or RNA can bind.  |
| Graphene's 'quantum leap' takes electronics a step closer Posted: 24 Jul 2011 10:55 AM PDT The Nobel Prize winning scientists Professor Andre Geim and Professor Kostya Novoselov have taken a huge step forward towards creating electronics from wonder material graphene.  |
