Electrocatalytic water splitting for hydrogen production is an appealing strategy to reduce carbon emissions and generate renewable fuels. This promising process, however, is limited by its sluggish reaction kinetics and high-cost catalysts. The two-dimensional (2D) transition metal dichalcogenides (TMDCs) have presented great potential as electrocatalytic materials due to their tunable bandgaps, abundant defective active sites, and good chemical stability. Consequently, phase engineering, defect engineering and interface engineering have been adopted to manipulate the electronic structure of TMDCs for boosting their exceptional catalytic performance. Particularly, it is essential to clarify the local structure of catalytically active sites of TMDCs and their structural evolution in catalytic reactions using atomic resolution electron microscopy and the booming in situ technologies, which is beneficial for exploring the underlying reaction mechanism. In this review, the growth regulation, characterization, particularly atomic configurations of active sites in TMDCs are summarized. The significant role of electron microscopy in the understanding of the growth mechanism, the controlled synthesis and functional optimization of 2D TMDCs are discussed. This review will shed light on the design and synthesis of novel electrocatalysts with high performance, as well as prompt the application of advanced electron microscopy in the research of materials science.

在复杂的国内外经济形势下,通过央行沟通引导预期对稳定经济变得越发关键。本文通过构建包含经济不确定性和央行沟通在内的理论模型,分析了央行沟通如何通过信息机制起作用,并探讨了经济不确定性可能产生的影响。理论模型分析表明,央行沟通通过信息机制能够降低市场波动,但是经济不确定性会对央行沟通的信息机制产生削弱作用。本文以中国人民银行发布的《中国货币政策执行报告》为沟通样本进行了实证分析,回归结果表明中国人民银行的沟通能够通过信息机制降低金融市场波动,但经济不确定性会抵消上述影响。在此基础上,本文将基准模型拓展到汇率市场,探讨了人民币汇率改革对信息机制的影响,并通过“8·11”汇改进一步在实证层面证实了央行沟通能够通过信息机制发挥作用。本文是对央行沟通理论机制研究的重要补充,不仅从经济不确定性视角为已有研究的分歧提供了一种解释,而且对改善央行沟通的政策效果、提高央行沟通引导预期的能力具有重要意义。

已有文献大多支持环境规制促进企业绿色创新的论断。本文基于中国绿色信贷政策的实践,发现当绿色信贷政策缺乏短期失败容忍时,绿色信贷政策的实施将对企业的绿色创新产生负面影响。具体而言,当绿色信贷政策对企业短期创新失败缺乏足够容忍时,政策的实施不仅未能激励污染企业增加绿色创新,反而导致了创新抑制效应,且政策短期失败容忍越低,对污染企业的绿色创新抑制作用则越强。值得注意的是,提高专利保护执法力度在一定程度上能够缓解这种负面影响。此外,环境规制对企业短期创新失败的容忍会对企业的环境行为选择产生重要影响,进而对不同影响机制的作用产生影响。由于对企业短期创新失败的容忍不足,中国绿色信贷政策通过“挤出”效应和资源约束效应抑制了污染企业的绿色创新投入。研究结果表明,对企业短期创新失败的容忍是环境规制促进企业绿色创新的重要条件。

目的:观察清心滋肾汤对前列腺癌内分泌治疗后潮热症状的临床疗效,初步探讨其疗效机制。方法:收集2021年12月至2022年12月就诊于江苏省中医院符合标准的患者共60例,随机分为观察组与对照组各30例,观察组予清心滋肾汤治疗,对照组予常规护理,观察周期为8周。观察两组患者治疗前后潮热频率、潮热程度、潮热评分、中老年男性睾酮缺乏症状自我测量表(ISS量表)评分和中医证候积分的改善情况,对比治疗前后血清内皮素-1(ET-1)、一氧化氮(NO)和降钙素基因相关肽(CGRP)及前列腺特异抗原(PSA)、睾酮的水平变化。结果:在疗效方面,与本组治疗前比较,观察组患者潮热频率下降,潮热程度减轻,潮热评分降低,ISS量表评分降低,中医证候积分下降(P<0.05);与对照组治疗后比较,观察组患者各项指标均优于对照组(P<0.05)。在实验室指标方面,与本组治疗前比较,观察组患者血清NO水平升高,ET-1水平降低,ET-1/NO下降,CGRP水平降低(P<0.05),而睾酮、PSA水平差异无统计学意义;治疗后观察组患者血清NO水平高于对照组,ET-1水平、ET-1/NO、CGRP水平低于对照组(P<0.05),但两组患者睾酮、PSA水平差异无统计学意义。结论:清心滋肾汤能显著改善前列腺癌患者内分泌治疗后潮热症状,其机制可能是通过调节血管舒缩因子的表达水平,改善血管舒缩功能,从而达到治疗潮热的目的。

本文从环境规制软约束的视角研究环境规制对经济可持续发展的影响.我们构建了一个以绿色创新投资门槛效应为基础的理论模型,首次将环境规制软约束引入波特假说的理论框架中,分析环境规制和环境规制软约束如何影响企业的创新和竞争力.利用2007–2014年中国工业SO2排污费征收标准调整这一准自然实验,本文综合利用中国工业企业数据库、中国上市公司数据和国家重点监控企业排污费数据,基于双重差分和三重差分模型,研究环境规制和环境规制软约束对企业竞争力的影响.研究结果显示,在经济转型时期的中国,环境保护和企业竞争力存在实现双赢的可能.面对相同的环境规制政策,波特假说是否可以实现受到环境规制软约束的影响.当企业面临环境规制软约束问题时,企业竞争力显著下降.通过进一步分析,本文发现环境规制软约束问题抑制了环境规制的创新激励.由于环境规制带来成本的增加,最终导致企业竞争力的下降.当较少存在环境规制软约束时,环境规制反而激发企业显著的创新效应,并通过创新补偿效应显著提升了企业的盈利能力.
