Journal.of Wuhan University of Technology(Materials Science) 2024年第3期39卷 627-638页

In order to explore the effect of vacancy defects on the structural,electronic,magnetic and optical properties of CoS_(2) and FeS_(2),first-principles calculation method was used to investigate the *** calculated results of materials without vacancy are consistent with those reported in the literatures,while the results of materials with vacancy defect were different from those of literatures due to the difference vacancy *** Co vacancy defect hardly changes the half-metallic characteristic of CoS_(2).The Fe vacancy defect changes FeS_(2) from semiconductor to half-metal,and the bottom of the spin-down conduction band changes from the p orbital state of S to the d(t_(2g))orbital state of Fe,while the top of the valence band remains the d orbital d(eg)state of *** half-metallic Co vacancy defects of CoS_(2) and Fe vacancy defects of FeS_(2) are expected to be used in spintronic devices.S vacancy defects make both CoS_(2) and FeS_(2) *** the Co and S vacancy defects lead to the decrease of the magnetic moment of CoS_(2),while both the Fe and S vacancy defects lead to the obvious magnetic property of FeS_(2).Vacancy defects enhance the absorption coefficient of infrared band and long band of visible light obviously,and produce obvious red shift phenomenon,which is expected to be used in photoelectric devices.

污染场地土壤-地下水系统中污染组分源强的精准识别是实现地下水污染高效治理与有效防控的根本前提.针对某固废填埋场地1号、3号地块地下水As(Ⅲ)浓度出现高值异常,采用统计相关分析方法分析了地下水中As(Ⅲ)与其他检出特征组分的相关关系,确定了As(Ⅲ)与Po_(4)^(3-)之间的竞争吸附反应是地下水中As(Ⅲ)污染的主要原因;随后采用表面络合模型(SCM)模拟竞争吸附反应,并建立了基于ToUGHREACT的场地土壤-地下水系统As(Ⅲ)污染组分反应运移模型;最后利用粒子群优化(PSo)算法构建了污染地块As(Ⅲ)污染的源强识别的模拟优化模型.结果显示:(1)固废中存在的磷酸盐能解释污染地块土壤不同深度As(Ⅲ)含量较背景值偏高的现象;(2)构建的土壤-地下水系统As(Ⅲ)运移模型可较好地模拟As(Ⅲ)与Po_(4)^(3-)竞争吸附反应;(3)优化识别出1号和3号地块的As(Ⅲ)污染源强分别为187.25μg·l^(-1)和192.49μg·l^(-1).研究表明,基于PSo算法的模拟优化模型具有识别精度高、计算速度快、稳定性好的特点,可用于解决此类土壤-地下水系统污染源强识别问题.

为探讨秀珍菇粉营养功能,将40只C57Bl/6小鼠随机分为正常对照组(normal control,NC)、秀珍菇低(GPl)、中(GPM)、高(GPH)剂量组,灌胃40 d。结果表明:GPM、GPH组血清谷氨酸氨基转移酶(alanine aminotrans-ferase,AlT)活性、尿素氮(bl.od urea nitrogen,BUN)和肌酐(creatinine,Crea)含量较NC组显著降低。与NC组相比,各实验组血清和肾丙二醛(malondialdehyde,MDA)含量明显降低;GPM、GPH组血清超氧化物歧化酶(superoxide dismutase,SoD)活性和肝过氧化氢酶(catalase,CAT)活性显著升高(Plutathione peroxidase,GSH-Px)活性较正常对照组均明显上升。各实验组胸腺指数和GPH组T淋巴细胞刺激指数显著高于NC组。灌胃秀珍菇还可上调小鼠肠道厚壁菌门菌群丰度,增加菌群物种数及Alpha和Beta多样性。综上所述,秀珍菇粉可改善肠道微生态环境,进而增强小鼠抗氧化和免疫功能。
