Nanoporous thin-film waveguide resonance sensors with wavelength interrogation over a broad bandwidth

Qi Z-M, Zhang Z., Liu Q., Lu D., Institute of Electronics, Chinese Academy of Sciences, CN

Nanoporous dielectric film based leaky-mode waveguide resonance sensors have attracted considerable attention because of their interesting features [1-4]. Such sensors generally operate in the angular interrogation mode [1-3]. The first application of the wavelength interrogation [...]

Rectifying properties of printed hybrid organic/inorganic diode on a flexible substrate

Lin J., Cui Z., Suzhou Institute of Nanotech, Chinese Academy of Sciences, CN

Printing as an additive fabrication method has in recent years attracted a great deal of attentions both in research community and industrial sectors, because of its low-cost and the capability of manufacturing electronic devices on [...]

Sustainable production of 1,2-propanediol: Clean hydrogenolysis of glycerol over highly stable Cu-Ce/SiO2 nanocatalyst

Huang Z., Cui F., Chen J., Xia C., Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, CN

Large quantities of glycerol are available as a reaction coproduct owing to the rapid development of biodiesel production by transesterification of vegetable oils and animal fats. The hydrogenolysis of glycerol to propanediols is one process [...]
