采用熔盐法制备了钙钛矿结构的钛酸锶立方块。通过浸渍法对所得钛酸锶进行表面离子修饰,得到表面负载无定形Cu(n)纳米团簇的新型可见光催化剂。利用ICP—AES、XRD、SEM、XPS、DRS等对其进行表征。通过光催化降解气相异丙醇对其可见光催化活性进行评价。研究发现,负载无定形Cu(II)团簇后,所得的催化剂Cu(II)-SrTiO3具有较好的可见光催化降解气相异丙醇的性能,能够有效地将异丙醇彻底矿化成二氧化碳。

在农村,母牛产犊后胎衣不下,时有发生。据笔者实践证明,以下两法确有疗效:  1.取白花丹(全草)、红蓖麻叶、倒扣草各250克。先将白花丹切碎,大火煮1小时,取其药液;把红蓖麻叶、倒扣草切碎捣烂,加洗米水3000毫升,然后冲入白花丹药液,连渣带水一起灌服。母牛服药后12小时左右即可排出胎衣。  2.取干糯米草1.5公斤(新鲜糯米草加倍),水煎,一次灌服,服后2~3小时胎衣即下。如未见效,可再服一次。
