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 Harnessing solar energy for self‐heating presents an effective strategy to suppress surface ice formation. In this paper, we fabricated nano‐silver‐modified multilayer graphene sheets (Ag@MGs) that integrate photothermal and superhydrophobic properties for anti‐icing applications.

Dizhen xuebao基于四川省姑咱台的钻孔应变观测数据，研究了2013年4月芦山MS7.0地震的应变异常。首先通过时间序列分解法去除芦山地震前后（2011年1月至2014年1月）观测数据的长期背景趋势和周期趋势，其次采用多通道奇异谱分析法分解数据，去除水位和气压引起的应变响应，最后提取应变数据中的震前负熵异常。结果表明：水位与水位应变响应的相关系数为−0.97；有96.1%天的日气压与其应变响应的相关系数的绝对值大于0.9，验证了本文环境响应去除算法的有效性；负熵异常累积与贝尼奥夫应变累积的一致性表明，震前4 ...

高寒区多源降水产品精度与水文模拟效果评估——以雅鲁藏布江流域和拉萨河流域为例
Shuitu Baochi Xuebao, 2023 卫星降水产品在缺资料地区开展水文气象研究及径流模拟中发挥着至关重要的作用,然而卫星降水产品的精度可能会影响径流模拟效果。采用多种统计指标和VIC水文模型综合评估5种卫星降水产品(CMORPH-BLD、GSMaP_Gauge、CMFD、MSWEP和PERSIANN-CDR)在雅鲁藏布江流域的精度和拉萨河流域的水文模拟效果。结果表明:(1) CMORPH_BLD和GSMaP_Gauge在少雨季存在低估,CMFD在少雨季与观测值具有很好的一致性。MSWEP和PERSIANN-CDR在多雨季和少雨季存在高估 ...
