化学电阻气体传感器对于空气质量、食品检测和人体呼吸有着重要作用.传感器上修饰物硫醇与待测的VOCs之间吸附的气敏机理分析是选择硫醇、预测吸附能力与特异性的重要手段.本文选取了11-巯基-1-十一醇(MUD)和4-甲氧基苄硫醇(MTT)两种常见的硫醇与六种典型的VOCs(乙醇ETN、异丙醇IPA、丙酮ACN、正己烷HXN、甲苯TLN、苯甲醛BND),基于密度泛函理论(DFT),计算其表面静电势(ESP)并建立气体吸附模型.在气体吸附模型的基础上计算其吸附能,并分析其弱相互作用,从微观角度解释气体吸附的作用机理.实验结果表明,具有羟基的MUD分子对同样有羟基的气体(如ETN、IPA)能够以氢键的方式吸附,具有较强的选择效果;具有苯环的MTT分子与具有苯环结构的气体分子(如TLN、BND)吸附时会在苯环之间形成π-π堆积,基于色散作用进行吸附,这表明MTT分子对具有苯环结构的气体有着较强的吸附作用.研究发现其色散作用吸附的强弱与分子的表面ESP绝对值有关.本文对于传感器表面修饰物吸附气体的气敏机理进行了探究,并对表面修饰物的选择和实验结果预测提供了理论指导.

The existence and release of fluid inclusions in bornite and its associated minerals, namely, quartz and calcite were investigated and confirmed. The structures, forms, and phases of these large quantities of fluid inclusions were also studied. A mass of fluid inclusions with various sizes, distributions, shapes, and phases exist in bornite and its associated minerals. Their sizes vary from a few micrometers to tens of micrometers, and the forms appear as negative crystals, or elongated, elliptical, and irregular. At room temperature, fluid inclusions were mainly characterized as gas-liquid two- phase. However, small amounts of fluid inclusions with pure gas phase and pure liquid single-phase were also observed in quartz and calcite. These fluid inclusions initially broke during the ore crushing and grinding process and then released into the flotation pulp in the flotation process. The quantitative analysis of fluid inclusions in the solution and the comparisons of mineral dissolution show that the amount of copper and iron released by fluid inclusions in the bornite sample is higher than the amount dissolved by the mineral; fluid inclusions in the associated gangue minerals, quartz, and calcite also make contribution.
