Phase‐Pure 2D Interfacial Perovskite Passivation for Stable and Efficient Photovoltaics

open access: yesCarbon Energy, EarlyView.
Phase‐pure 2D interfacial passivation eliminates mixed‐phase energetic disorder, establishes favorable band alignment, and suppresses interfacial non‐radiative recombination. This review elucidates deterministic phase‐purity control, defect and lattice reconstruction mechanisms, and scalable manufacturing strategies, highlighting how phase‐pure 2D/3D ...

Experimental study on burning rate and flame geometry in construction tunnel fires under high geothermal conditions

open access: yesDeep Underground Science and Engineering, EarlyView.
Abstract As tunnel construction advances in lengths and depths, the construction of tunnels in high geothermal environments has become increasingly common, raising significant fire risks. In this study, a 1:20 scale model tunnel test platform was constructed to investigate the effects of a high geothermal environment on fire behavior in tunnels during ...

Chinese traditional Leadership Philosophy as cultural re-source for Chinese Business Leadership [PDF]

open access: yes, 2016
作为文化资源的中国传统哲学以现代中国商业领导力 研究人员、教育人员和实践人员都了解目前缺乏同有效的中国商业领导力开发相关的针对性文化项目,中国的现代管理教育仍然是“原样照搬”西方的项目。由此所导致的新一代中国管理人员的低效发展在人力资源发展和企业战略发展领域产生了大量的问题,并影响了中国企业的效率。 本论文《作为文化资源的中国传统哲学以现代中国商业领导力》揭示了中国传统哲学作为文化源是如何推动有效商业领导力的发展的。由于中国人对于传统价值观的坚守,中国传统领导哲学可以成为一个有效的商务领导力概念。此外 ...
