冰洲石-玻璃组合e光超高透偏光棱镜

为了既节省稀有昂贵的冰洲石晶体材料，又尽量提高偏光棱镜的透射比，设计了一种冰洲石晶体与光学玻璃组合的方法。叙述以布儒斯特角入射来提高偏光棱镜e光透射比的设计方案。该棱镜可用甘油或有机硅胶将FK 2玻璃与冰洲石晶体胶合而成。理论分析和实验测试表明，该棱镜的透射比高于96％，消光比优于10-5，在一定情况下可以取代纯冰洲石晶体材料的偏光棱镜。

Ion and solvent transfer discrimination at a nickel hydroxide film exposed to LiOH by combined electrochemical quartz crystal microbalance (EQCM) and probe beam deflection (PBD) techniques

A combined electrochemical quartz crystal microbalance (EQCM) and probe beam deflection (PBD) instrument was used to monitor the mobile species transfers associated with the redox processes of thin (Γ100–150 nmol cm⁻²) α- and β-nickel hydroxide films exposed to aqueous LiOH solution. A comparison of the measured PBD signal with the predicted PBD profiles, calculated by temporal convolution analysis of the current and mass responses, enabled the contributions to redox switching of anion (OH⁻) and solvent (H₂O) transfers to be discriminated quantitatively. The responses from the combined instrument are reconciled in terms of H⁺ deintercalation/intercalation within the nickel hydroxide structure as OH⁻ ions enter/exit the film. Hydroxide ion movement is associated with a counterflux of water. Thin nickel hydroxide films show a gradual α→β phase transformation with continuous voltammetric cycling, especially when the films are exposed to high concentrations of electrolyte. α-Films are characterised by OH⁻ transfers that dominate the H⁺ and H₂O movements; β-films are characterised by an increased participation of water and protons to the exchange dynamics.
