Photoactive complexes of nonprecious transition metals, mainly including those in the first-row and partially the second-row of the Periodic table of elements, have received increasing attention in view of their low cost and long-term sustainability. They are recognized as promising alternatives to noble transition metal complex congeners that have been extensively studied in optoelectronic devices, artificial photosynthesis, photocatalysis, biodiagnostics, and therapeutics, etc. This review is devoted to a comprehensive summary on the classical and recent advances on photoactive nonprecious transition metal complexes, including photoactive Zr, V, Cr, Mo, and W complexes, Mn complexes and hybrids, Fe, Co, Ni, and Cu complexes, and Zn and Cd complexes and hybrids. A particular focus is given on the molecular design, modulation of photophysical and photochemical properties, and applications of the representative and lately-developed nonprecious metal complexes. In addition, a perspective on the future development in this field is provided at the end of this review.

采用根箱实验,基于定量PCR技术研究非常规水源(再生水和养殖废水)灌溉及生物炭添加后根际土、非根际土及玉米根部病原菌的赋存情况.结果发现,灌溉时间、土壤类型可显著影响土壤中病原菌的整体分布.相较于蒸馏水灌溉下根际土、非根际土的单个病原菌,再生水灌溉下病原菌变化为-0.74-0.17个数量级,养殖废水灌溉下为-0.14-0.60个数量级.生物炭对土壤中病原菌的影响因灌溉水源、灌溉时间而改变,可使再生水及养殖废水灌溉下病原菌检出量最高降低0.35、0.39个数量级.但再生水及养殖废水灌溉可使玉米根部病原菌检出量最高增加1.17、2.20个数量级,生物炭又使非常规水源灌溉下其检出量最高增加0.60、1.08个数量级,带来潜在的健康风险.
