The sluggish lithium-ion(li-ion)transport kinetics in graphite anode hinders its application in fast-charging li-ion batteries(liBs).Here,we develop an ionpumping interphase(IPI)on graphdiyne(GDY)/graphite heterojunction anodes to boost the ionic transport kinetics and enable high-performance,fast-charging *** IPI changed the ion solvation/desolvation environment by covalent/non-covalent interactions with li ions or solvents to optimize solid-electrolyte interphase(SEI)and regulate li-ion transport *** studied the in situ growth of few-layer GDY on graphite surface(GDY/graphite)as the IPI and found that the strong interaction between GDY and li ions enabled surface-induced modification of the ion solvation behavior and surface-assisted desolvation effect to accelerate the li-ion desolvation process.A functional anion-derived SEI layer with improved li-ion conductivity was *** with the generated built-in electric field at GDY/graphite hetero-interface self-pumping li ions to intercalate into the graphite,the li-ion transport kinetics was significantly enhanced to effectively eliminate li plating and large voltage polarization of the graphite anodes.A fast li intercalation in GDY/graphite without li oversaturation at the edge of the graphite was directly *** superior performance with high capacity(139.2 mA h g^(-1))and long lifespan(1650 cycles)under extremely fast-charging conditions(20 C,1 C=372 mA g^(-1))was achieved on GDY/graphite *** at low temperatures(-20℃),a specific capacity of 128.4 mA h g^(-1) was achieved with a capacity retention of 80%after 500 cycles at a 2 C rate.

Theileria is a tick-borne intracellular protozoan that typically parasitizes erythrocytes,lymphocytes,and macrophages and causes acute clinical symptoms in host animals,including high fever,anemia,jaundice,and swelling of superficial lymph nodes[1].Theileriosis can lead to high mortality rates,and its rising global prevalence has resulted in significant economic losses to livestock husbandry and the national economy[2].

Currently, the application of synthetic biology to artificially manipulate and utilize organisms for the synthesis of desired products such as nanomaterials with excellent fluorescence properties is attracting considerable attention. However, it is still difficult to obtain designed products efficiently due to insufficient knowledge of the biosynthetic mechanisms. The thioredoxin（TRX） and glutathione（GSH） pathways are generally conserved thiol-reductase systems that protect organisms from oxidative stress and are involved in selenium（Se） metabolism. In this study, we revealed the pivotal role of cytoplasmic TRX pathway in regulating the metabolism of Na2SeO3during the live-cell synthesis of cadmium-selenium quantum dots（Cd Se QDs） in Saccharomyces cerevisiae by regulating the expression level of genes related to TRX pathway and measuring the intracellular content of selenocysteine（Se Cys）. The determination of Se Cys metabolism in yeast with GSH pathway-related genes deleted demonstrated that the TRX pathway played a more significant role in Se Cys metabolism than GSH pathway. A 6.4-fold enhancement in the synthetic yield of Cd Se QDs was achieved through the overexpression of TRX pathway-related genes,improvement of synthetic procedure, and supplementation of GSH based on the understanding of biological *** the mechanism of CdSe QDs live-cell synthesis facilitates the precise manipulation of biological processes for the synthesis of inorganic nanomaterials.
