Rare Metals, EarlyView.ABSTRACT Converting CO2 to CH4 under mild conditions is a promising strategy for solving environmental and energy problems, but also a challenge. In this work, the low‐temperature CO2 hydrogenation process over Ni/CeO2 catalysts was significantly accelerated by optimizing the H2 dissociation ability of Ni through the size effect, thus A‐Ni/CeO2 with an

The Study on Diagnosis and Countermeasure of the Basic Level Employee’s Satisfaction [PDF]
, 2015 员工满意度研究在国际学术界一直是一个长盛不衰的课题，但直到近年来才开始引起国内学术界的重视，研究方法的本土化程度不高，研究设计的深度与广度也稍显欠缺。本文旨在以A企业员工这一群体作为研究对象，对其工作满意度的影响因素进行行业化的探讨。 本论文以某台资企业为例，对该型企业基层员工满意度进行研究。主要研究影响台资企业员工满意度的因素和因素特征，包括各个影响因素之间的相关性、对员工满意度影响的显著性等等。本研究通过深度访谈，完善了A企业员工满意度问卷设计。取得调查数据后，分析其原因 ...

Dual‐Stage Heat Treatment for Enhanced Hydrogen Storage Properties of Mg−Ni−Y Alloys
Rare Metals, EarlyView.ABSTRACT Mg−Ni−Y alloy is considered to be one of the most promising hydrogen storage materials, but its high dehydrogenation energy barrier hinders its practical application. A dual‐stage heat treatment (490°C × 4 h + 550°C × 4 h) is applied to optimize the microstructure and hydrogen storage performance of a vacuum‐melted Mg94Ni3Y3 alloy.

Analysis on Regulation of P2P Online Lending Industry(HONGLING CATITAL as an example [PDF]
, 2016 近年来，P2P网络借贷行业进入了快速发展的阶段，每年的平台数量以及成交量均呈现数倍的增长，行业内出现了红岭创投、人人贷、陆金所等知名平台，而平台的运营模式也有所区别，不同的平台利用各自模式的特点进行大力推广，同时也出现了分化。部分平台由于有国有企业、上市公司的背景，更能够获取投资者的信任，规模越做越大，但更多的平台由于没有很好的“靠山”，在营销和推广上遭遇瓶颈，仅仅维持在一个相对低的规模水平，发展艰难，最终有一批P2P平台选择退出。 由于缺乏监管，市场上的P2P平台参差不齐，截止2015年12月 ...

Rare Metals, EarlyView.ABSTRACT Aqueous zinc‐ion batteries (AZIBs) hold great promise for safe and sustainable energy storage, but their commercialization is impeded by severe Zn dendrite growth and interfacial instability. To address these challenges, we propose a defect engineering strategy employing ultrafine ZnAl2O4 (ZAO) nanoparticles (∼5 nm) with oxygen vacancy defects

China’s Outward Foreign Direct Investment: an Analytical Framework on the Motivation-Effects -Countermearsures [PDF]
, 2015 近年来，中国贸易顺差持续扩大，外汇储备余额迅速增加。巨额的外汇储备提高了中国抵御国际金融风险的能力，但同时也给中国的经济发展带来巨大的通胀压力。随着中国贸易额的不断增加，中国出口贸易屡遭外国贸易保护主义壁垒。对于以上两个问题，通过对外直接投资可以得到有效的解决。当前，与外商直接投资相比较，中国对外直接投资水平还比较低。而随着经济全球一体化，各国之间的经贸往来日益频繁，一国仅依靠自身资源难于持续发展，而通过对外直接投资改变母国经济的发展方式，能够使母国经济发展获得更大的推动力。在这样的背景下 ...

The Defects and Perfection of Collective Labor Dispute System to Deal With Collective Labor Disputes in Xiamen [PDF]
, 2016 目前我国正处在各项制度改革和社会转型时期，经济和劳动关系表现越来越市场化、多样化和复杂化，劳资矛盾引发的劳动争议屡有发生。自2008年以来，全国劳动争议总计均在150万件左右，劳动争议已成为主要社会矛盾之一。尤其由劳资矛盾引发的集体劳动争议案件显著增加，时常发生工人围堵政府办公场所、集体上访的事件，必然会破坏社会基本的公平正义，威胁社会的安定和谐，其结果往往容易引发社会问题，如何处理好集体劳动争议，成为一项艰巨的任务。劳动争议必须先由劳动仲裁处理，劳动仲裁应该着力于处理好集体劳动争议 ...

Laser‐Driven Halide Exchange and High‐Resolution Multicolor Patterning of Perovskite Films
Rare Metals, EarlyView.ABSTRACT Translating the excellent properties of metal halide perovskites (MHPs) into practical flexible optoelectronic devices requires high‐resolution multicolor patterning techniques that are compatible with post‐fabrication processing. However, such a capability has remained elusive.
