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 new chromium complex emits light in elusive NIR-II wavelength

Many applications, from fiber-optic telecommunications to biomedical imaging processes require substances that emit light in the near-infrared range (NIR). A research team in Switzerland has now developed the first chromium ...

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, ...
