Ef fective and robust catalyst is the core of water splitting to produce ***, we report an anionic etching method to tailor the sulfur vacancy(VS) of NiS_(2) to further enhance the electrocatalytic performance for hydrogen evolution reaction(HER). With the VS concentration change from 2.4% to 8.5%, the H* adsorption strength on S sites changed and NiS_(2)-VS 5.9% shows the most optimized H* adsorption for HER with an ultralow onset potential(68 m V) and has long-term stability for 100 h in 1 M KOH media. In situ attenuated-total-reflection Fourier transform infrared spectroscopy(ATR-FTIRS) measurements are usually used to monitor the adsorption of intermediates. The S-H* peak of the Ni S_(2)-VS 5.9% appears at a very low voltage, which is favorable for the HER in alkaline media. Density functional theory calculations also demonstrate the Ni S_(2)-VS 5.9% has the optimal |ΔG^(H*)| of 0.17 e V. This work offers a simple and promising pathway to enhance catalytic activity via precise vacancies strategy.

Due to a prolonged operation time and low mass transfer efficiency, the primary challenge in the aeration process of non-Newtonian fluids is the high energy consumption, which is closely related to the form and rate of impeller, ventilation, rheological properties and bubble morphology in the reactor. In this perspective, through optimal computational fluid dynamics models and experiments, the relationship between power consumption, volumetric mass transfer rate(kLa) and initial bubble size(d0) was constructed to establish an efficient operation mode for the aeration process of non-Newtonian fluids. It was found that reducing the d0could significantly increase the oxygen mass transfer rate, resulting in an obvious decrease in the ventilation volume and impeller speed. When d0was regulated within 2-5 mm,an optimal kLa could be achieved, and 21% of power consumption could be saved, compared to the case of bubbles with a diameter of 10 mm.

目的观察面部脂溢性皮炎的皮肤镜下特征,分析脂溢性皮炎在外用激素类药膏治疗形成激素依赖性皮炎的过程中皮损皮肤镜下特征的变化规律。方法选择2018年1月—2018年12月本院门诊就诊的55例脂溢性皮炎患者,17例原为脂溢性皮炎患者曾局部外用激素治疗史和28例激素依赖性皮炎患者,所有患者镜下进行皮肤镜检查。分析各组患者典型皮损皮肤镜下特征(背景颜色、血管形态、血管排列及附加指征)。结果脂溢性皮炎患者皮肤镜下特征为:点状血管(40/72.7%)、线状血管(47/85.5%)、白色鳞屑(25/45.5%)、黄色鳞屑(9/16.4%)和毛囊角栓(45/81.8%)。外用激素治疗可以使面部皮下血管形态由点状、线状血管逐渐发展为线状、分支状血管,最后形成粗细不均血管。血管排列由散在逐渐发展为杂乱、网状分布,最后相互连接形成树枝状。结论脂溢性皮炎皮肤镜下特征为毛囊角栓、线状血管、点状血管和白色鳞屑。外用激素治疗可以使皮下血管逐渐由散在分布点状、线状血管发展为杂乱、网状分布的线状或分枝状血管,最后形成粗细不均的树枝状血管。
