Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Lung cancer remains the leading cause of cancer‐related deaths worldwide, yet immune checkpoint blockade (ICB) is often compromised by an immunosuppressive tumor microenvironment (TME) with acidosis, hypoxia, and poor T cell infiltration. Here, we develop a TME‐responsive nanoplatform (MgH2@Lip/PD‐L1) that couples hydrogen gas therapy with PD ...

How Many Floods Have Occurred in China in the Past Decade? A Perspective From Social Media
Earth's Future, Volume 13, Issue 4, April 2025.Abstract Global climate change has led to frequent and widespread flood disasters in China. Traditional flood disaster investigations mainly focus on major flood events, and small‐scale flood events are often overlooked. This study utilized the Sina Weibo social media platform to detect flood events in 370 cities in China from 2012 to 2023.

Dianci bileiqi, 1975 提高绝缘子金属附件热镀锌层均匀性,对延长绝缘子的使用寿命是有好处的。在批林批孔运动的推动下,我们对提高热镀锌层均匀性的问题进行了研究,已初见成效。实践证明,提高热镀锌层均匀性的关键在于工艺方法的改进。我厂旧的热镀锌工艺的特点是：(1)镀锌温度高,一般在550—600℃; (2)在锌液中加铝,增加锌液的流动性和提高锌层表面的光泽;(3)不使用"助镀溶剂",酸洗烘干后立即镀锌;(4)锌层镀后没有冷却就用"卡"、"墩"的方法除掉表面的积锌。这就使锌层薄而不均匀,致使锌层硫酸铜试验次数很低 ...

Dianci bileiqi, 1975 在伟大领袖毛主席“自力更生”方针指引下,我厂设计、制造出一台两工位通讯绝缘子半自动成型机,现已投入生产。该机体积小、结构简单、工效高,只需一人操作,比一般手工钢丝刀成型可提高工效2倍。除放泥段和取坯是手工外,整个成型过程都是自动的,故光坯规格很一致,劳动强度也较轻。其主要技术参数是:主轴转速4转/分 ...
