The electrochemical performances of fluorinated carbon nanofibres have been tested for a use as cathode material in primary lithium battery using LiBF4 PC:DME 1M as electrolyte. For a very narrow fluorination range [420-450°C], the fluorine content in the carbon nanofibres increases up to CF0.78 and so do both the energy and the power densities. A maximum of 8057 W.kg power density has been rea...
Nitrogen-enriched porous carbon materials made via the carbonization of polyacrylonitrile containing block copolymer act as efficient and highly selective CO(2) sorbents. Nitrogen content and surface area, which are both influenced by pyrolysis temperature and atmosphere, are crucial for CO(2) adsorption performance.
This review focuses on chemical sensors based on cyclodextrin (CD) derivatives. This has been a field of classical interest, and is now of current interest for numerous scientists. First, typical chemical sensors using chromophore appended CDs are mentioned. Various "turn-off" and "turn-on" fluorescent chemical sensors, in which fluorescence intensity was decreased or increased by complexation ...
