Angewandte Chemie International Edition, EarlyView.A Cu‐Ni‐W tri‐component catalyst enables efficient nitrate‐to‐ammonia conversion under pulsed electrolysis. Combined experimental and theoretical studies attribute its performance to component synergism and regulated intermediates. Its facile adaptation for glycerol valorization to formic acid underscores a versatile system design concept, advancing ...

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 ...

Advanced Physics Research, EarlyView.A functional interface engineering strategy is proposed to tune upconversion of NaErF4@NaYF4 core–shell nanocrystals by adjusting the amount of CF3COONa in the precursor during the shell growth. It is able to introduce controllable lattice defects at the core–shell interface to manipulate energy migration paths and non‐radiative transition of Er3 ...

11～13世纪中国剪刀形态的转变及可能的外来影响 [PDF]
, 2013 11~13世纪,中国古代剪刀的形式逐渐从交股剪刀转变为双股剪刀。考古资料显示双股剪刀在这一时期内更早、更多出现于北方辽、金统治区域。在中国境内双股剪刀有可能是从北向南传播的。联系双股剪刀在西方世界很早就得到广泛使用,认为中国双股剪刀有可能是通过欧亚草原从西向东传播而来。从技术史角度来看,烛剪并没有导致双股剪刀在中国的出现,这与西方早期双股剪主要用于剪切金属构成对比。东西方剪刀制造工艺存在相似之处,这有利于双股剪刀技术在中国能够被迅速掌握 ...

Archaeological Prospection, EarlyView.ABSTRACT This paper tackles one key limitation in the analysis of Iron Age communities in the Northwestern Iberian Peninsula: the limited exploration of areas beyond the fortified settlements known as castros (hillforts). The vast majority of archaeological studies have focused exclusively on the areas inside the walls of these settlements, which are ...
