沿自然原因和人为原因形成的水分梯度,对若尔盖高寒湿地沼泽土和泥炭土的有机碳(SOC)和活性有机碳(LC)进行了研究。研究表明,若尔盖高寒湿地沼泽土有机碳和全氮沿水分梯度(减小)变化趋势一致,即在表层0—10cm湿润环境中的有机碳和全氮含量远高于淹水环境和过渡地带,而10—30 cm沿水分梯度差异变小。泥炭土的有机碳和氮素含量在湿润环境远大于淹水(流水)环境。这说明当时的挖沟排水疏干沼泽使得相当一部分土壤有机碳或者释放到大气中,或者随水流流失。沼泽土活性有机碳在表层0—10 cm沿水分梯度升高;在10—30 cm差异变小,与有机碳和氮素的变化趋势一致。泥炭土的活性有机碳沿水分梯度升高,与泥炭土有机碳和氮素变化趋势一致。这一方面反映了两种土壤类型成土过程的不同,另一方面也反映了自然原因和人为原因造成的差异。沼泽土的碳氮比沿水分梯度有降低的趋势而泥炭土的碳氮比沿水分梯度有升高的趋势。此外,高寒沼泽土碳氮比,pH值以及机械组成都是影响土壤有机碳,氮素和活性有机碳的重要因子。

Direct in vivo conversion of astrocytes into functional new neurons induced by neural transcription factors has been recognized as a potential new therapeutic intervention for neural injury and degenerative disorders. However, a few recent studies have claimed that neural transcription factors cannot convert astrocytes into neurons, attributing the converted neurons to pre-existing neurons mis-expressing transgenes. In this study, we overexpressed three distinct neural transcription factors––NeuroD1, Ascl1, and Dlx2––in reactive astrocytes in mouse cortices subjected to stab injury, resulting in a series of significant changes in astrocyte properties. Initially, the three neural transcription factors were exclusively expressed in the nuclei of astrocytes. Over time, however, these astrocytes gradually adopted neuronal morphology, and the neural transcription factors was gradually observed in the nuclei of neuron-like cells instead of astrocytes. Furthermore,we noted that transcription factor-infected astrocytes showed a progressive decrease in the expression of astrocytic markers AQP4(astrocyte endfeet signal), CX43(gap junction signal), and S100β. Importantly, none of these changes could be attributed to transgene leakage into preexisting neurons. Therefore, our findings suggest that neural transcription factors such as NeuroD1, Ascl1, and Dlx2 can effectively convert reactive astrocytes into neurons in the adult mammalian brain.

Solution-processed Cu（In,Ga）Se2（CIGS） solar cells suffer from serious carrier recombination and power conversion efficiency（PCE） loss because of the poor film properties and easy formation of ***, we propose Ag&Se co-selenization strategy to enhance the crystallization and passivate harmful defects of the CIGS films. The formation of Ag-Se phase during the selenization process enables the formation of large grains and suppresses the deep level defects. It is found that Ag doping can enlarge the depletion region width, lower the Urbach energy and prolong the carrier lifetime. As a result, a champion solution-processed CIGS solar cell presents a high efficiency of 16.48% with the highly improved opencircuit voltage（VOC） of 662 m V and fill factor（FF） of 75.8%. This work provides an efficient strategy to prepare high quality solution-processed CIGS films for high-performance CIGS solar cells.
