Elemental Geochemistry and Uranium-series Chronology of the Ferromanganese Crusts from the West Pacific [PDF]
, 2016 本文选取西太平洋5块富钴结壳样品，应用电沉积制源方法和α能谱测量手段获取了富钴结壳表层铀、钍及镤同位素的深度分布；通过ICP-MS测量手段获得结壳表层18种常、微量元素含量；对西太平洋富钴结壳的生长年代学及元素地球化学进行了分析与研究，并对晚第四纪气候对结壳生长的影响进行探讨。本研究的主要结果如下： （1）在Talvitie（1972）法的基础上主要探究了电流、沉积时间以及沉积溶液的pH值对电沉积效果的影响。通过对铀、钍电沉积最优实验条件的探究，确定了铀电沉积的最佳条件是pH值为2.0 ...

Laser‐Driven Halide Exchange and High‐Resolution Multicolor Patterning of Perovskite Films
Rare Metals, EarlyView.ABSTRACT Translating the excellent properties of metal halide perovskites (MHPs) into practical flexible optoelectronic devices requires high‐resolution multicolor patterning techniques that are compatible with post‐fabrication processing. However, such a capability has remained elusive.

Rare Metals, EarlyView.ABSTRACT As a promising alternative to sluggish Li2CO3‐based Li‐CO2 electrochemistry, Li2C2O4 offers a favorable 2e− discharge pathway, yet its selective formation and reversible decomposition remain debated. Herein, we propose a nonmetal‐metal synergistic catalyst—B‐Ti coregulated layered transition metal boride Ti18B18O9/graphene (B‐Ti/TiBOG)—to ...

Zhongguo shiyan zhenduanxue, 2015 结核病是目前全球最常见的传染性疾病之一,结核分枝杆菌相关检查在各种结核病确诊过程中有着举足轻重的作用。传统诊断结核病主要依赖于结核菌涂片,经抗酸染色然后在显微镜下观察,尽管该方法的特异性较强,但是其敏感性较低,且对某些类型结核病如骨结核、中枢神经系统结核来说标本采集难度较大[1-2],从而使得该方法在临床上的应用受到了极大的限制。随着研究的深入,诸多新技术逐步用于结核病的诊断 ...

Rare Metals, EarlyView.ABSTRACT The Schottky barrier height (SBH), which serves as a pivotal determinant of charge carrier injection efficiency in electronic devices, critically governs electrical behavior at metal/semiconductor interfaces. However, pronounced metal‐induced gap states at metal contact interfaces induce Fermi‐level pinning, which constrains the ...

Zhongguo shiyan zhenduanxue, 2015 非结核性分枝杆菌（NTM）是指在分枝杆菌属中,除了结核分枝杆菌复合群（人型、牛型、非洲型和田鼠型结核分枝杆菌）和麻风分枝杆菌以外的分枝杆菌。非结核分支杆菌脑膜炎是由NTM引起。由于非结核分支杆菌与结核分支杆菌同为分支杆菌属,故非结核分支杆菌脑膜炎与结核分支杆菌脑膜炎的临床症状、X线胸片特点极为相似,单纯靠胸片和痰液结核分枝杆菌抗酸染色涂片是无法区分的 ...
