Pro‐ATO/Allicin Liposomes for Dual‐Pathway Targeting of p53‐Mutant Tumors

Advanced Science, EarlyView.
Schematic illustration of the “pro‐ATO”/allicin liposomal strategy. Liposomal encapsulation improves the stability and bioavailability of both agents while masking allicin's odor. Upon release in the tumor microenvironment, ATO reactivates structural p53 mutants, and allicin inhibits ATR signaling while releasing H2S, collectively inducing synthetic ...

Nitrogen‐Boosted H2O2 Production of Arginine‐Polyphenol Nanozyme Drives Oxidative Eustress for Hair Regeneration

Advanced Science, EarlyView.
PEA nanoenzymes are assembled from L‐arginine and EGCG. The nitrogen element in arginine enhances the thermodynamic feasibility of H2O2 production through PEA's oxygen reduction catalysis, enabling nitrogen‐dependent H2O2 release. Intradermal delivery of PEA via microneedles promotes efficient H2O2 synthesis, thereby stimulating regrowth in telogen ...

Analysis on the characteristics and driving forces of spatiotemporal changes of Zhejiang water system(浙江省水域系统时空变化特征及驱动力分析)

Zhejiang Daxue xuebao. Lixue ban, 2022
基于浙江省1980—2020年8期土地利用数据，分析了浙江省不同时期水域系统时空格局、水面率、转换趋势、景观格局等特征，揭示了水域系统面积变化的驱动因素。结果表明：（1）浙江省水域面积总体呈增加趋势，河流、滩地面积缩减，湖泊、水库坑塘、滩涂面积增加。水域系统转移集中于河流、湖泊和沿海一侧。（2）浙江省水域景观格局MPS、NP、LST、FRA、CCONTAG指数上升，PD、ED、LPI、COHESION、AI指数下降，突出反映了水域景观破碎化、离散化、复杂化。（3）不同地级市水域系统面积存在差异 ...

Synergistic Modulation of Ru–O Bond Covalency via Ba/Fe Co‐Doping and Oxygen‐Vacancy Engineering for Efficient Wide‐pH Oxygen Evolution

Advanced Science, EarlyView.
Ba/Fe co‐doping and oxygen vacancy engineering synergistically modulate the Ru–O bond covalency in RuO2, leading to markedly enhanced OER activity across wide‐pH electrolytes. ABSTRACT Developing efficient and stable oxygen evolution reaction (OER) catalysts across a wide‐pH range is critical for practical water electrolysis.

浙江乌岩岭发现红翅绿鸠

野生动物学报, 2021
2020年2月10日在浙江乌岩岭国家级自然保护区双坑口保护站(119°40’23″E,27°42’37″N,海拔695 m)发现1只红翅绿鸠(Treron sieboldii)雄鸟尸体。该鸟腹部近白色,腹部两侧及尾下覆羽具灰斑,翼覆羽绛红色,上背偏灰,头顶橘黄,脚红色。经查阅相关文献资料后,确定红翅绿鸠为浙江省鸟类分布新纪录。凭证标本保存在浙江乌岩岭国家级自然保护区管理中心。

Interfacial Synergy in a Band‐Aligned Low‐Dimensional Heterojunction Toward Broadband Photodetection

Advanced Science, EarlyView.
Monolithically integrating sensing and communication, a Ta2NiSe5/Sb2Te3 heterojunction achieves visible‐to‐near‐infrared photovoltaics with high‐speed terahertz photo‐thermoelectric detection at room temperature. By engineering a Type‐II van der Waals heterojunction, we overcome the intrinsic spectral limitations and disparate physical requirements of ...

From Design to Prototype: High‐Sensitivity Tri‐Mode Operation Photodetectors Based on 1T‐2H Hybrid MoS2

Advanced Science, EarlyView.
This work demonstrates a phase‐engineered MoS2 photodetector that dynamically switches among photocapacitive (PCC), photovoltaic (PV), and photoconductive (PC) modes. By transforming the traditionally parasitic capacitance into an active signal source, the device achieves self‐powered, high‐sensitivity detection with a fast response of 19.2 ms, and a ...

活动范围对青鳉鱼(Oryzias latipes)运动模式的影响

Haiyang yu huzhao
重尾分布现象广泛存在于自然界的各种生物运动模式之中，重尾分布现象会随环境的变化而变化。鱼类为适应生存环境，往往会选择更加高效的个体运动模式。以青鳉鱼(Oryzias latipes)为研究对象，在相同浅水条件(5 cm)下，控制其活动范围，探究青鳉鱼在不同水域面积(1.0 m×1.0 m、0.6 m×0.6 m、0.4 m×0.4 m、0.2 m×0.2 m以及0.1 m×0.1 m)条件下的运动模式。利用MATLAB软件将青鳉鱼的运动轨迹转换为具体数据，通过移动速度、移动加速度 ...
