Orthogonal Stimulus‐Responsive Ca3Ga2Ge3O12: Pr3+ for Real‐Time X‐Ray Dosimetry and Dynamic Information Encryption

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Multimodal luminescent materials are crucial for advanced information encryption, real‐time dosimetry, and high‐resolution bioimaging, yet integrating orthogonal stimulus‐responsiveness into a single‐component system is challenging. Herein, we report a Pr3+‐doped Ca3Ga2Ge3O12 (CGGO: Pr3+) garnet phosphor that exhibits orthogonally addressable ...

Effects of Warming and Sea-level Rise on the Growth of Kandelia obovata and Laguncularia racemosa Seedlings [PDF]

open access: yes, 2013
据政府间气候变化专门委员会(IPCC)估计,未来二十年全球平均气温将以每十年增加大约0.2ºC的速率变暖。未来100年全球平均气温大约上升2oC。全球变暖引起海洋自身的热膨胀与陆地上冰川、冰帽、极地冰盖的消融,导致海平面上升。根据中国国家海洋局公报,未来100年我国沿海海平面上升幅度约为30cm。红树林是分布在热带和亚热带海岸潮间带的木本植物群落,它将首当其冲受到全球气候变化的影响:既受到气温上升的影响,又同时受到海平面上升的影响。全球气温升高和海平面上升对红树林的影响是交互的。 秋茄 ...

Bimetallic Mo/Fe‐Doped CoP2 Nanoleaf Array as a Bifunctional Electrocatalyst for Overall Water Splitting

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT The development of efficient and stable bifunctional catalysts remains a key challenge for green hydrogen production via electrochemical water splitting. In this study, a bimetallic Mo/Fe‐doped CoP2 nanoleaf array anchored on carbon cloth (Mo, Fe‐CoP2@CC) was synthesized from zeolitic imidazolate framework‐L (ZIF‐L) via an ion‐exchange and low‐

轴向约束杆件高温屈曲后强度对网架结构高温极限承载力的影响

open access: yesJianzhu Gangjiegou Jinzhan, 2019
局部火灾下,网架结构升温具有明显的非均匀性,结构中温度高的杆件热膨胀受到温度较低杆件的约束,使得网架结构的部分杆件具有显著的约束杆件高温力学特征。基于局部火灾下网架结构力学反应全过程数值追踪技术,考察结构升温非均匀性、结构荷载比、火源位置和结构跨度影响因素下,网架结构杆件高温屈曲后强度对整体结构抗火极限承载力的贡献。研究表明:当结构温度分布非均匀系数η在0.2≤η0.5时,杆件高温屈曲后强度对结构抗火极限承载力的贡献先逐渐减小然后转变为逐渐增大。上述研究结论可为建立网架结构第2阶段失效准则提供理论依据。
