Laser writing may enable 'electronic nose' for multi-gas sensor

Environmental sensors are a step closer to simultaneously sniffing out multiple gases that could indicate disease or pollution, thanks to a Penn State collaboration. Huanyu "Larry" Cheng, assistant professor of engineering ...

A molecular ripcord for chemical reactions

Researchers at Eindhoven University of Technology (the Netherlands) have developed an entirely new method for starting chemical reactions. For the first time they used mechanical forces to control catalytic activity - one ...

Lab 3-D prints microbes to enhance biomaterials

Lawrence Livermore National Laboratory (LLNL) scientists have developed a new method for 3-D printing living microbes in controlled patterns, expanding the potential for using engineered bacteria to recover rare-earth metals, ...

Light and nickel found to simplify cross-coupling reactions

Cross-coupling reactions—chemical transformations in which two fragments are joined together—are a valuable tool in the synthesis of organic molecules. Applications range from drug development and synthesis of naturally ...

Transition metal complexes: Mixed works better

A team at BESSY II has investigated how various iron-complex compounds process energy from incident light. They were able to show why certain compounds have the potential to convert light into electrical energy. The results ...

Screens set to go green

Fitting the screens of electronic devices, such as televisions and smartphones, with a new display technology called 'organic light-emitting diodes' (OLEDs) will reduce their energy consumption, but such screens currently ...
