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.

为了进一步探究中强地震发生前GNSS坐标时序中是否存在中短期异常现象,通过分析2023年2月23日塔吉克斯坦M_(S)7.2地震前后中国大陆构造环境监测网络(简称:“陆态网络”)塔什库尔干、布伦口GNSS基准站观测资料的变化特征,发现该地震震前塔什库尔干、布伦口均出现较为明显的GNSS基准站时间序列异常现象,震前EW向存在趋势性W向运动,震后E向加速;震前NS向趋势性S向运动,临震前状态快速改变,布伦口在震后还显示出7.3 mm的EW向永久性形变,研究结果表明GNSS在地震发生短临阶段具有重要的预测意义。与2015年12月7日塔吉克斯坦M S7.4地震进行对比发现,两次M S≥7.0地震对塔什库尔干、布伦口基准站的影响差异较大。2015年12月7日塔吉克斯坦M S7.4地震为左旋走滑,影响方向主要为NE向,而2023年2月23日塔吉克斯坦M_(S)7.2地震为右旋走滑,影响方向主要为SE向。震前基线均有挤压缩短的前兆异常显示。梳理站点异常出现情况,发现异常持续时间越长、异常出现次数越多,发震震级可能越大。

Recently, we introduced the twist polynomials of delta-matroids and gave a characterization of even normal binary delta-matroids whose twist polynomials have only one term and posed a problem:what would happen for odd binary delta-matroids? In this paper, we show that a normal binary deltamatroid whose twist polynomials have only one term if and only if each connected component of the intersection graph of the delta-matroid is either a complete graph of odd order or a single vertex with a loop.

Hydroformylation could convert olefins and syngas （mixture of H2and CO） into aldehydes with a great atomic *** transformation serves as one of the most prominent processes in modern chemical industry, as it provides over 10million tons of aldehydes as feedstock for our daily essential products such as plasticizers, paints, solvents, and pharmaceuticals. This process generally requires efficient yet robust catalyst to realize decent efficacy. Compared with metals such as Co, Ru, and Pd, rhodium （Rh）-based catalysts stand out due to its superior activity even under mild reaction conditions, and dominate over 70%of global hydroformylation processes.

The infiltration of glioblastoma multiforme(GBM) is predominantly characterized by diffuse spread, contributing significantly to therapy resistance and recurrence of GBM. In this study, we reveal that microtubule deacetylation, mediated through the downregulation of fibronectin type III and SPRY domain-containing 1(FSD1), plays a pivotal role in promoting GBM diffuse infiltration. FSD1 directly interacts with histone deacetylase 6(HDAC6) at its second catalytic domain, thereby impeding its deacetylase activity on α-tubulin and preventing microtubule deacetylation and depolymerization. This inhibitory interaction is disrupted upon phosphorylation of FSD1 at its Ser317 and Ser324 residues by activated CDK5, leading to FSD1 dissociation from microtubules and facilitating HDAC6-mediated α-tubulin deacetylation. Furthermore, increased expression of FSD1 or interference with FSD1 phosphorylation reduces microtubule deacetylation, suppresses invasion of GBM stem cells, and ultimately mitigates tumor infiltration in orthotopic GBM xenografts. Importantly, GBM tissues exhibit diminished levels of FSD1 expression, correlating with microtubule deacetylation and unfavorable clinical outcomes in GBM patients. These findings elucidate the mechanistic involvement of microtubule deacetylation in driving GBM cell invasion and offer potential avenues for managing GBM infiltration.

为揭示行距和播量对河北滨海盐碱地苜蓿光合特性及产量的影响,本研究以‘中苜一号’为材料,设置了15 cm(R1),20 cm(R2),25 cm(R3)3个水平的行距和7.5 kg·hm^(-2)(S0),15 kg·hm^(-2)(S1),22.5 kg·hm^(-2)(S2),30 kg·hm^(-2)(S3),37.5 kg·hm^(-2)(S4)5个水平的播量,共15个处理,研究了苜蓿叶片色素含量、荧光参数、光合曲线及产量的变化规律。结果表明:随着行距的增大苜蓿叶片叶绿素含量(Chlorophyll content,ChlM)和氮-黄酮醇指数(Nitrogen flavonol index,NFI)均呈下降趋势,R1S2处理的苜蓿叶片NFI最高。通径分析表明,行距和播量配置通过调节叶片ChlM,花青素含量(Anthocyanin content,AnthM),黄酮醇含量(Flavonol content,FlvM),最大光合效率(Maximal photochemical efficiency,F v/F m),调节性能量耗散的量子产量(Quantum yield of regulatory energy dissipation,Y(NPQ))和表观光合电子传递速率(Electron transfer rate,ETR)影响苜蓿光合作用和产量的形成。在本研究条件下,行距15 cm、播量约22 kg·hm^(-2)配置下苜蓿产量最高。
