Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT The pollution caused by antibiotics to aquatic ecosystems is becoming increasingly serious, thus more effective treatment methods are urgently required. Although the photocatalytic degradation behavior of tetracycline (TC) is relatively well understood, sulfamethoxazole (SMZ), an emerging pollutant originating from large‐scale livestock ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Biomass‐based hydrogels are widely regarded as ideal substrates for self‐powered wearable sensors. However, the practical applications of hydrogels are commonly limited by their inherent low strength and toughness, which restrict their capacity to withstand repeated stretching, bending and other mechanical loads arising from human motion in ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT High‐yield photocatalytic H2O2 production in sacrificial agent‐free pure water constitutes a critical bottleneck requiring urgent advances in energy catalysis. Although ZnIn2S4 (ZIS) exhibits favourable visible light absorption, it is plagued by severe bulk charge carrier recombination and scarce accessible surface‐active sites.

, 2006 本实用新型涉及防水材料，具体说是一种管孔止水条。在现有技术中，在混凝土现浇渠道过程中，混凝土预制渠道间的伸缩缝是通过止水条来防止水的渗漏，现有的止水条的结构为实心的条状物，其材料采用橡胶、塑料等防水材料，所以其弹性较差，而且材料的成本较高。本实用新型在原有的止水条基材的内部至少设置一根弹性管，其外表面轮廓为圆形、方形、梯形或X形等，适应缝隙的形状。因而本实用新型节省材料，降低成本，孔适应外界变形能力强 ...

, 2018 为了研究丹河人工湿地在不同温度下对低C／N值河水中氨氮的去除能力，于2015年1月“月对丹河人工湿地各处理单元进、出水中NH4-N和COD进行了逐日监测。结果显示，沉水植物型表面流-垂直流复合人工湿地对河水中SH；-N的平均去除率随温度的升高从50．1％上升到80．2％，低温条件下，NH4-N主要在垂直流湿地单元中被去除。温度〈15℃时，复合系统中垂直流单元对NH4-N的去除率介于50．6％-72．3％之间，显著高于单-垂直流人工湿地（27．5％-45．8 ...

Habitat and spatial trends of U.K. wintering waterbird populations over 50 years
Conservation Biology, Volume 40, Issue 5, October 2026.Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...

Scientists’ warning on the global destruction of rock outcrop ecosystems
Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

, 2010 水庫供水的主要來源為本身儲存的水量及入流量，但入流量具有不確定性，因此在不預期的乾旱時期水庫供水量有時無法滿足既定的需求量。良好的水庫營運規則可使缺水的影響減到最低，如何將水庫入流量的不確定性併入水庫的供水規則為本文的研究重點。對於水庫入流量，本文考慮歷史紀錄流量中最小入流量與入流量條件平均值（定義為已知前月入流量時本月入流量之平均值），並以其對需水量的關係作為水庫的供水指標。水庫的營運結果則以缺水特性，包括缺水延時、缺水量及缺水頻率等相關缺水指標來評估。文末則以簡化的石門水庫單目標供水系統為例 ...

Gongye shui chuli, 1986 水中碳酸钙垢的生成，主要是由于水的蒸发浓缩使水中含盐量逐渐升高，当它处于过饱和状态时，就可能发生晶体析出。循环冷却水通过换热器使水温上升，回到冷却塔中喷淋进行热交换，部份水份蒸发而使水温下降，由于曝气使水中的一部份碳酸氢根离子变成碳酸根离予，同时pH值上升，这样造成碳酸钙在水中的量逐渐增多，超过它的溶解度，但仍然看不到碳酸钙结晶，它是以过饱和的状态存在于水中。
