文中采用严格数值分析方法系统研究了亚波长金属槽阵列的吸收增强效应。针对单层、双层矩形槽阵列特点,数值模拟了结构参数和金属类型对阵列吸收效率的影响。研究结果表明,亚波长金属矩形槽阵列的吸收增强现象主要来自槽内局域模式共振效应,且窄槽的共振更强,吸收效率更高。满足共振效应时与单层结构相比,双层矩形槽阵列上层槽宽是调控吸收峰增强效应的主导参数,下层槽宽对吸收峰数值影响很小,仅调控下层槽共振深度。文中对双层结构的分析为算法对V型槽、梯形槽的吸收增强设计提供了数值模拟参考,保障吸收增强的同时有效降低加工难度,也为以亚波长金属槽阵列为吸收增强单元的器件设计提供了重要参数指导。

糖尿病肾脏病（DKD）是造成慢性肾脏病和终末期肾病的主要原因，如何对其进行更有效的预防和治疗至关重要。近年来，随着对炎症和纤维化在DKD发病及进展机制中的作用认识的加深，如何围绕炎症、纤维化这个肾脏病变进展的关键环节，深化DKD的防控理论显得尤为重要。一保双抗是针对DKD的发病研究进展提出的防治思路，其中“一保”指保肾护肾，去除或减少肾脏损伤的内外危险因素，包括血糖、血压及血脂等内在肾损伤病因代谢指标的控制，以及避免肾毒性药物等外在促损伤因素的二次打击;“双抗”指抗炎和抗纤维化，针对DKD炎症和纤维化靶标，旨在阻断肾脏恶化的病理生理过程，延缓甚至逆转肾脏疾病进展，减少终末期肾病的发生。该文从DKD的相关危险因素和发病机制、相关循证学依据等多个维度，充分阐述“一保双抗”在DKD防治上的重要性及未来应用前景，以期推动DKD防治理论体系的建设，指导未来的临床治疗革新。

Nano-Micro Letters 2014年第4期6卷 340-346页

作者： Bosi Yin siwen zhang Xin Zheng Fengyu Qu Xiang Wu Key Laboratory for Photonic and Electronic Bandgap Materials Ministry of Education Harbin Normal University

In this paper, for the first time, we report the synthesis of nanoscale cuprous chloride(Cu Cl) cubic structure by a facile hydrothermal route. A possible mechanism for the growth of those nanostructures is proposed based on the experimental results. It is discovered that the existence of HCl could affect the surface of Cu Cl nanocubes. This unique cube-like nanostructure with rough surface significantly enhances the electroactive surface areas of Cu Cl, leading to a high special capacitance of 376 m F cm-2at the current density of 1.0 m A cm-2. There is still a good reversibility with cycling efficiency of 88.8 % after 2,000 cycles, demonstrating its excellent long-term cycling stability and might be the promising candidates as the excellent electrode material.

Hierarchically assembled SnO_2 microflowers were synthesized by a facile hydrothermal *** emission scanning electron microscope results showed these hierarchical nanostructures were built from two dimensional nanosheets with the thicknesses of about 50 nm. Photoluminescence spectrum of the asobtained products demonstrated a strong visual emission peak at 564 nm. The photochemical measurement results indicated that the as-prepared sample exhibits excellent photocatalytic performance. These three dimensional SnO_2 hierarchical nanostructures may have potential applications in waste water purification.
