光催化还原是处理水溶液体系中六价铬(Cr(VI))的一种新方法.层状铋(Bi)基材料具有增强的光捕获能力和可调的带隙能量,被认为是一种光催化还原去除Cr(VI)的有效材料.本文从修饰策略(如异质结、缺陷工程和掺杂)和工艺变量(如溶液p H和添加剂的类型/数量)等方面,对用于光催化还原处理Cr(VI)的铋基材料的改进机制进行深入总结.此外,采用工业上用作关键指标的优值系数(FoM),对各种铋基材料的性能进行评估.结果发现,平均粒径为5-10 nm,具有shuriken形状的BiVo_(4)具有最高的FoM值(3.45×10^(-5) molg^(-1)Wh^(-1)),且其光催化还原性能最好.同时,与其他非铋基催化剂相比,BiVo_(4)的光催化还原Cr(VI)性能也具有很好的优势.但是,目前铋基催化剂成本较高,且光催化还原过程能耗较大,距离大规模实际应用还有一定的距离.未来,为实现铋基催化剂光催化还原处理含Cr(VI)废水的大规模应用,应大幅度降低催化剂的生产成本,并提高催化剂光子吸收效率从而进一步提高能源利用率.

The production of transgenic farm animals(e.g., cattle) via genome engineering for the gain or loss of gene functions is an important undertaking. In the initial stages of genome engineering, DNA micro-injection into one-cell stage embryos(zygotes) followed by embryo transfer into a recipient was performed because of the ease of the ***, as this approach resulted in severe mosaicism and has a low efficiency, it is not typically employed in the cattle as priority, unlike in mice. To overcome the above issue with micro-injection in cattle, somatic cell nuclear transfer(SCNT) was introduced and successfully used to produce cloned livestock. The application of SCNT for the production of transgenic livestock represents a significant advancement, but its development speed is relatively slow because of abnormal reprogramming and low gene targeting efficiency. Recent genome editing technologies(e.g.,ZFN, TALeN, and CRISPR-Cas9) have been rapidly adapted for applications in cattle and great results have been achieved in several fields such as disease models and bioreactors. In the future, genome engineering technologies wil accelerate our understanding of genetic traits in bovine and wil be readily adapted for bio-medical applications in cattle.

In this study,high entropy metallic glasses(HeMGs)were developed through a combination of concepts for designing metallic glasses(main element+transition metal+metalloid element)and high-entropy alloys(more than five elements,each element having an atomic concentration between 5 at.%and 35 at.%).The developed metallic glass alloys are composed of Co-Fe-Ni main elements,transition metals(Cr,Mo)and metalloid elements(C,B).Moreover,the present work reports the thermal,mechanical and magnetic properties of(CoFeNi)(50)(CrMo)(50-x)(CB)x alloys with x=20,25,*** developed as-spun HeMGs exhibit typical paramagnetic properties even for a high amount of ferromagnetic elements(Co,Fe,and Ni)and have high elastic modulus(103–160 GPa)and hardness(14–27 GPa),thus possessing mechanical properties similar to well-known Co-based metallic glasses(Co-Cr-Mo-C-B system).In addition,some of the bulk samples prepared with a diameter of 2 mm form bulk metallic glasses with a high compressive strength around 3.5 *** mechanisms determining the stability of the supercooled liquid,as well as the paramagnetic and mechanical properties for the developed non-equiatomic HeMGs,are discussed.
