消费者权益保护是ESG的一项重要内容。消费者保护包括产品披露、消费者教育及公平公正对待等。我们必须在金融产品的销售过程中做到充分的信息披露,把金融产品的底层资产说清楚、讲明白,并做好风险披露及客户适合度的匹配。如果在销售过程中还能进一步使得消费者关注到关于气候变化及环境保护的问题,以及何谓ESG,那将是一件更有意义的事。

为探讨根际细菌和葡萄耐涝性的关系,采用盆栽淹水法,对1年生巨峰葡萄扦插苗进行淹水胁迫21d以及淹水后恢复7 d的处理,运用16S rRNA高通量测序技术对土壤细菌进行测序,分析其细菌群落组成和结构,探究淹水胁迫对巨峰葡萄根际细菌群落结构组成的影响。结果显示:淹水21 d巨峰葡萄根际细菌的丰度最高,淹水14 d巨峰葡萄的根际细菌多样性最高;胁迫后恢复期间,硫杆菌属(Thiobacillus)相对丰度显著增加;根系细菌功能预测分析显示脂质、萜类和聚酮类化合物代谢有显著变化。结果表明,短期淹水胁迫促进植物产生代谢物改变细菌群落以应对逆境胁迫,但长时间淹水使植物代谢发生紊乱,导致潜在有害细菌类群的丰度增加,植物有益菌群减少。

In this study, the ZrB2/Al nanocomposites were fabricated via in-situ reaction of the Al-K2ZrF6-KBF4 system, assisted with ultrasonic vibration and spiral electromagnetic stirring. Microstructure, tensile property and creep behavior of the fabricated nanocomposites were further investigated. Microstructure observation showed that the ultrasonic vibration could prevent the fast growth as well as break the clusters of in-situ synthesized nanoparticles in melt, resulted in smaller size (10-50 nm) and relatively more uniform distribution of the in-situ nanoparticles located on the boundary of and/or inside the aluminum matrix grains in the final composites. The fabricated nanocomposites exhibited an enhancement in both strength and ductility, due to the elevated work hardening ability, i.e., improved dislocation propagating ability and decreased dynamic recovery of the existing dislocations induced by the in-situ nanoparticles. Meanwhile, the nanocomposites exhibited excellent creep resistance ability, which was about 2-18 times higher than those of the corresponding aluminum matrix. The stress exponent of 5 was identified for the fabricated nanocomposites, which suggested that their creep behavior was related to dislocation climb mechanism. The enhanced creep resistance of the nanocomposites was attributed to the Orowan strengthening and grain boundary strengthening induced by the ZrB2 nanoparticles. Thus, the ultrasonicchemical in-situ reaction promises a low cost but effective way to fabricate aluminum nanocomposites with high strength and high creep resistance.

Bone marrow mesenchymal stem cells （MSCs） from rats were transfected with Rn-siRNA-caveolin-1 and differentiated into neuron-like cells using fasudil hydrochloride. Membrane ultrastructural changes in MSCs were observed under atomic force microscopy. Caveolin-l-transfected rat MSCs exhibited weak nuclear refraction, dense caveolae and long finger-like cellular processes prior to fasudil hydrochloride treatment. MSCs differentiating into neuron-like cells exhibited weak nuclear refraction and large cellular processes without caveolae. We hypothesize that caveolin-1 plays an important role in the regulation of bone marrow MSC differentiating into neuron-like cells.
