Unraveling post-growth mechanisms of monolayer CsPbBr3 nanocubes:Laser-enhanced transformations and cathodoluminescence-electron microscopy correlations

引用

Journal of Energy Chemistry 2025年第1期100卷 146-156页

作者： Mingxing Li xiaoge wang Xiaofan Cao Zhiqun He Chunjun Liang Mingxing Chen Jing Ju Fangtian You Key Laboratory of Luminescence and Optical Information Ministry of Education Institute of Optoelectronic Technology Beijing Jiaotong University Beijing National Laboratory for Molecular Sciences (BNLMS) College of Chemistry and Molecular Engineering Peking University

Lead-halide perovskite nanoparticles（LHP NPs） are highly promising materials for next-generation displays and solid-state lighting due to their exceptional optical properties. However, their inherent instability presents a significant challenge. Recent advances have demonstrated that optoelectronic devices based on monolayer nanoparticle films exhibit both high luminescence efficiency and long-term *** research demonstrates that mobility limitations and anisotropic alignments in CsPbBr3nanocube monolayer films are key to their stabilization, hindering spontaneous growth through face-to-face fusion and resulting in the formation of connecting necks in a diagonal direction. Introducing laser irradiation confirmed this by significantly accelerating nanocubes growth, increasing mobility, and enhancing local structural ordering, leading to larger and more regularly shaped nanosheets. Fourier transform infrared spectroscopy and energy dispersive spectroscopy line-scan analyses indicated that laser irradiation did not disrupt the ligand structure. Transmission electron microscopy and correlative cathodoluminescence electron microscopy revealed the effects of post-growth and heterogeneous structures, including enhanced luminescence and inhomogeneous intensity in the nanosheets. These findings deepen the understanding of the post-growth mechanism of monolayer nanoparticles and the structure-emission correlation and highlight the unique role of laser irradiation in directing the formation of well-defined and regular nanostructures.

Morality-improvement in Great Expectations

引用

校园英语 2017年第5期 242-243页

作者：吕玲 wang xiaoge 青岛黄海学院 Qingdao Huanghai University

Great Expectations chiefly describes Pip’s hard pursuit to his false expectations. In this process, Pip’s moral concept and life value gradually grow mature. Meanwhile Dickens shows us various ugly phenomena of Victorian times through the eyes of Pip. This paper presents Pip’s notion about"status". From no notion about upper class to great desire of being a gentleman to his realization of his gentry dream to the collapse of his dream, Pip understand social class is not the real standard of judging a person.

Dynamic Development of Armaments in East Asia after the Cold War

引用

Peace 2014年第1期 55-63页

作者： Guo Rui wang xiaoge Department of International Relations Jiling University

After the end of the Cold War, military spending and arms purchases of many countries( regions) continue to show a rising trend, especially in East Asia. However, the East Asian countries military spending share of GDP does not change significantly, and is generally lower than the overall level before the end of the Cold War, and the armaments build-up does not develop into a vicious expansion situation. Dynamic factors of arms development in East Asia is multifaceted and cannot simply be attributed to the so-called "competitive pressure" onto each other. The inherent rationality for replacing the existing weapons, institutionalizing military production and emerging domestic security threats as well as the "action-reaction" factor also exert significant impacts. The impact of "technological imperative" factor, leading to great enthusiasm of the East Asian countries to buy advanced armaments, and also to a certain blind arms development, should not be underestimated. With the U.S. strong "return to Asia", competitive arms development in East Asia would be further strengthened, the result of which should attract great concerns among East Asian countries.

Achieving ultrahigh electrochemical performance by surface design and nanoconfined water manipulation

The effects of nanoconfined water and the charge storage mechanism are crucial to achieving the ultrahigh electrochemical performance of two-dimensional transition metal carbides(MXenes). We propose a facile method to manipulate nanoconfined water through surface chemistry modification. By introducing oxygen and nitrogen surface groups, more active sites were created for Ti3C2MXene, and the interlayer spacing was significantly increased by accommodating three-layer nanoconfined water. Exceptionally high capacitance of 550 F g-1(2000 F cm-3) was obtained with outstanding high-rate performance. The atomic scale elucidation of the layer-dependent properties of nanoconfined water and pseudocapacitive charge storage was deeply probed through a combination of ‘computational and experimental microscopy’. We believe that an understanding of, and a manipulation strategy for, nanoconfined water will shed light on ways to improve the electrochemical performance of MXene and other two-dimensional materials.
