Enhanced Magnetocaloric Effect in Tb‐Co‐Ni Magnets via Chemical Pressure
Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Magnetic refrigeration materials are significantly needed in versatile modern industries, including scientific research, aerospace, and health care, due to their potential applications in gas liquefaction and storage. Herein, a significantly enhanced magnetocaloric effect with a suitable operation temperature range of 53–114 K and a giant ...

Gongye shui chuli, 2009 采用烧杯试验考察了投加高铁酸钾强化混凝去除矿井水中铅、镉、铁、锰的效果。结果表明,高铁酸钾为30mg/L时,混凝沉淀对低浓度矿井水中铅、镉、铁、锰的去除率分别约为55%、28%、93%、54%;高铁酸钾对模拟高浓度矿井水中铅、镉、铁、锰的去除率随pH的升高而提高,pH8～10范围内对铅、镉、铁、锰有较好的去除效果,去除率可分别达到约95%、61%、97%和92%。处理后的矿井水中重金属含量可以达到饮用水标准,这给矿井水提供了很好的利用前景。

Zhongguo shiyan zhenduanxue, 2006 目的探讨缺铁性贫血与促红细胞生成素的关系。方法采用EPO测定法,血浆EPO浓度的测定运用了ELISA测定法,用Blotkalbumin取代血液BSA进行非特异性蛋白结合部分的实验,并采用了YHA、EPO、EPOGIN标准,在进行老鼠血浆浓度测定时,YHA———EPO标准的运用的稳妥性的认证。结论通过实验分析由缺铁性贫血而导致血液中携氧能力的下降,会使血浆中EPO浓度增加,促进红细胞的生成。此外,在铁缺乏的状态下,特久训练会促成EPO的生成。然而,对于机能增加而相关联的携氧能力的改善 ...

Novos Estudos - CEBRAP, 2021 O objetivo deste artigo é argumentar que situações de privação material são inerentemente coercitivas. Para isso, avaliam-se teorias da justiça para as quais a pobreza não representaria uma forma de intervenção coercitiva em contextos de livre-mercado. Argumenta-se aqui que a pobreza precisa ser concebida como uma posição social subordinada e, portanto,

Shuitu Baochi Xuebao, 2011 通过分析添加含铁材料(Fe2O3、Fe2(SO4)3)和稀土材料(CeCl3、LaCl3)后矿区污染土壤中交换态砷(As)含量和土壤pH值的变化规律,研究这2类材料对矿区土壤As的固定效果以及对土壤性质的影响。结果表明,Fe2O3对As固定效果不明显,当Fe2O3最大添加量为8g/kg(分别按Fe计)时,土壤中交换态As含量仅降低了3.81%,其他3种材料在本试验条件下表现出良好的效果,其中Fe2(SO4)3和LaCl3固定As的效果相当,CeCl3次之。当这3种材料的添加量分别为2,4,8g/kg ...
