However, its application is curbed by photo-generated carrier recombination and photo corrosion. Although constructing S-scheme heterojunctions by combining ZnIn_(2)S_(4)with other semiconductors can solve these problems, the photocatalytic activity of S-scheme heterojunctions can be further improved. Therefore, this short review summarizes modification strategies of ZnIn_(2)S_(4)-based S-scheme heterojunctions. This article also introduces the concept, design principles, and characterization methods of ZnIn_(2)S_(4)-based S-scheme heterojunction. Finally, current challenges and future research focuses related to ZnIn_(2)S_(4)-based S-scheme heterojunctions are discussed and summarized, including the utilization of advanced in-situ characterization techniques to further illuminate the photocatalytic mechanism, the DFT-assisted design of catalysts to increase the selectivity of products during photocatalytic CO_(2) reduction, and extending the photoresponse of ZnIn_(2)S_(4)-based S-scheme heterojunction to near-infrared range, etc.展开更多

Grain protein content （ GPC ） is an important nutritional quality trait for rice and many other crops. Therefore, it will be very significant to increase GPC and improve rice quality. This paper mainly reviewed the genetic studies GPC in rice, mapping and cloning of QTLs and genes associated with GPC. However, little is known about the molecular mechanism and gene function related to GPC in rice. Thus, here we put forward the genetic strategy by gene pyramiding or molecular marker assisted selection to improve GPC and nutritional quality in rice. This review could provide important information for genetic improvement of grain nutritional quality of rice.展开更多

Nanoparticles enter the blood circulation as foreign objects. On the one hand, they may cause a series of inflammatory reactions and immune reactions, resulting in the rapid elimination of immune cells and the reticuloendothelial system, affecting their durability in the blood circulation. On the other hand, the premise of the drug-carrying system to play a therapeutic role depends on whether they cause coagulation and platelet activation, the absence of hemolysis and the elimination of immune cells. For different forms of nano drug-carrying systems, we can find the characteristics, elements and coping strategies of adverse blood reactions that we can find in previous researches. These adverse reactions may include destruction of blood cells, abnormal coagulation system, abnormal effects of plasma proteins, abnormal blood cell behavior, adverse immune and inflammatory reactions, and excessive vascular stimulation. In order to provide help for future research and formulation work on the blood compatibility of nano drug carriers.展开更多

In order to improve this situation and promote the harmonious development of economy and environment, we must do a good job in environmental monitoring. By monitoring the types and contents of substances in the ecological environment, we can obtain valuable data, and then compare them with the requirements of relevant standards and take reasonable solutions to ensure the quality level of the ecological environment. In actual work, the operation and implementation of monitoring will be affected by personnel, equipment and environment, which will limit the normal development of some work. Therefore, relevant departments should intensify the research on ecological environment monitoring and formulate scientific and effective countermeasures for existing problems.展开更多
