光是甘蔗生长发育的重要环境因子,充足的光照是甘蔗生育期中分蘖形成和生长的基础。然而,广西特殊的地形地貌限制了蔗田的光照条件,从而影响甘蔗分蘖及分蘖成茎和蔗茎产量。为揭示弱光胁迫对甘蔗分蘖生长发育及其内源激素含量的影响,以生态适应性较好的甘蔗优良品种‘桂糖29号’为试验材料,全自然光强为对照,通过遮荫形成不同的弱光胁迫,调查不同弱光胁迫下甘蔗分蘖及生长情况,同时分析胁迫15、30、45、60 d时甘蔗叶片中叶绿素含量及生长素吲哚乙酸(IAA)、赤霉素(GA_3)、脱落酸(ABA)、玉米素核苷(ZR)含量的变化。结果表明:弱光胁迫致使甘蔗分蘖生长发育明显延滞,甘蔗分蘖发生时间至少滞后15 d,严重的导致分蘖不发生和死亡;甘蔗叶片叶绿素含量均显著升高,但株高生长和茎径增粗均显著地受抑制,进而导致植株生物量积累显著减少。进一步研究发现,弱光胁迫下不同生育时期甘蔗叶片中内源激素含量大小为:ZR>IAA>ABA>GA_3。在适应弱光胁迫过程中,甘蔗叶片的IAA、ABA和ZR含量均显著升高,IAA/ABA、IAA/ZR比值在分蘖适应寡照胁迫中表现为升高;GA_3含量和GA_3/ABA比值均先降后升;ZR含量和ZR/ABA比值表现为升高。这些内源激素含量和比例变化可能是甘蔗分蘖进程受到抑制的关键因素之一。

目的探究奥美拉唑和埃索美拉唑对上消化道出血疗效及安全性影响。方法采用随机数字表法将96例上消化道出血患者分为奥美拉唑组(A组,n=48)和埃索美拉唑组(B组,n=48)。A组患者予以常规治疗+奥美拉唑静滴,B组患者予以常规治疗+埃索美拉唑静滴。比较两组患者疗效和不良反应,观察治疗前后红细胞压积(PCV)、血清尿素氮(BUN)水平变化情况。结果两组患者治疗总有效率比较,差异无统计学意义(P>0.05);治疗5d后,两组患者PCV较治疗前升高,血清BUN则较治疗前降低(P0.05);A组不良反应发生率(25.00%)高于B组(8.33%)(P<0.05)。结论奥美拉唑和埃索美拉唑治疗上消化道出血的疗效均较高,且无明显差异,但埃索美拉唑不良反应少,安全性更高。

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.
