Suppression of uncontrollable dendrite growth and water-induced side reactions of Zn metal anodes is crucial for achieving long-lasting cycling stability and facilitating the practical implementations of aqueous Zn-metal *** address these challenges,we report in this study a functional nitro-cellulose interfacial layer(NCIL)on the surface of Zn anodes enlightened by a nitro-coordination chemistry *** NCIL exhibits strong zincophilicity and superior coordination capability with Zn^(2+)due to the highly electronegative and highly nucleophilic nature of the nitro functional *** characteristic facilitates a rapid Zn-ion desolvation process and homogeneous Zn plating,effectively preventing H_(2) evolution and dendrite ***,the negatively charged surface of NCIL acts as a shield,repelling SO_(4)^(2-)anions and inhibiting corrosive reactions on the Zn ***,reversible and stable Zn plating/stripping is achieved for over 5100 h at a current density of 1 mA cm^(-2),which is nearly 30 times longer than that of bare Zn ***,the Zn/V_(2)O_(5) full cells with the functional interface layer deliver a high-capacity retention of 80.3%for over 10,000 cycles at 5 A g^(-1).This research offers valuable insights for the rational development of advanced protective interface layers in order to achieve ultra-long-lifeZnmetal batteries.

沙门菌(Salmonella)是革兰氏阴性的兼性胞内菌,可引起其广泛宿主的一系列疾病,严重时可导致全身性感染,威胁生命安全。沙门菌致病岛2(SPI2)是与沙门菌全身性感染密切相关的重要毒力基因簇,其编码的Ⅲ型分泌系统2(T3SS2)在沙门菌侵入宿主细胞后开始组装合成,经该装置分泌的多种效应蛋白对沙门菌在宿主细胞内的生存和增殖起着重要作用。近些年来,与沙门菌T3SS2相关的研究一直都是病原微生物领域关注的焦点之一。本文简要综述了SPI2的基因特征、SPI2基因表达的调控、T3SS2的结构和组成、T3SS2的效应蛋白及与T3SS2相关的疫苗研究等方面的主要研究进展。

We have investigated the feedback control of the cooperative dynamics of two coupled electrochemical oscillators that is induced merely by external noise. The interacting electrochemical cells are modeled with parameter values at which no autonomous oscillations occur, and each unit is forced by its own source of random fluctuations. Application of delayed feedback to only one of two subsystems is shown to be able to change the coherence and time scales of noise-induced oscillations either in the given subsystem or globally. It can also induce or suppress stochastic resonance under the certain conditions.
