Investigation on process mechanism of a novel energy-saving synthesis for high performance Li_(4)Ti_(5)O_(12) anode material

Li_(4)Ti_(5)O_(12)(LTO) anode material demonstrates superior cycling performance due to its stable spinel structure and high lithiation/de-lithiation potential.Herein,a novel energy-saving solid-phase synthesis route for LTO has been successfully designed,employing the cheap industrial intermediate product of metatitanic acid (HTO) as titanium source.Through the in-situ Fourier transform infrared spectroscopy (FTIR)and ex-situ X-ray diffraction (XRD),it is revealed for the first time that the amorphous crystal structure of HTO is more conducive for the Li+insertion,making it possible to prepare LTO at a relatively lower sintering temperature.Utilizing the dehydration carbonization reaction between glucose and sulfuric acid,an ingenious strategy of glucose pre-coating is adopted to avoid the generation of Li_(2)SO_(4) impurity caused by the residual sulfuric acid on the surface of HTO,which meanwhile enhances the conductivity and inhibits the particle growth of LTO.The obtained ALTO@C anode material consequently exhibits excellent electrochemical performance that 132.0 m Ah g^(-1)is remained even at 20 C,and ultra low decay rate of 0.015% per cycle is achieved during 1000 cycles at 2 C.Remarkably,LiCoO_(2)//ALTO@C full cell delivers conspicuous low-temperature property (130.7 m Ah g^(-1)at 0.5 C and almost no attenuation after 300 cycles under-20℃).

Potential Application of TCM Sophoridine in Regulating Intensity of Autophagy to Treat PKD

Nearly all cells have primary cilia( PC) composed of microtubules,primary cilia mainly functioning as sensing various signals of the environment and coordinating intracellular signaling pathways. Autophagy is an adaptive response of cells to environmental stress such as starvation/inflammation and infection. Many ciliopathies may induce autophagy. Polycystic kidney disease( PKD) is the most common ciliopathy,with the incidence of 1/500 to 1/1 000 in the world. A typical symptom of the PKD is the chronic development of multiple renal cysts that may eventually develop into advanced kidney disease. Sophoridine is an alkaloid extracted from the traditional Chinese medicinal plant Sophora alopecuroides L. It is a new antitumor drug which has the function of inducing cell autophagy. This paper mainly discussed the possibility of treating PKD through sophoridine inducing autophagy.

Effects of Injection of Oregano Oil Submicron Emulsion on Lipopolysaccharide-induced Pneumonia in Rats

[Objectives]To explore the effects of injection of oregano oil submicron emulsion on lipopolysaccharide-induced pneumonia in rats.[Methods]Rats induced by lipopolysaccharide were used as animal models of acute pneumonia.The experiment was divided into blank group,model group,administration group and positive drug control group.The morphology of lung tissue and the changes of cells and inflammatory factors in each group were observed,and the anti-inflammatory effects of injection of oregano oil submicron emulsion.[Results]The injection of oregano oil submicron emulsion can improve the pathological injury of rat lung tissue,inhibit the release of IL-6,IL-10,TNF-αcytokines induced by lipopolysaccharide,and significantly reduce the value of CRP.[Conclusions]Oregano oil submicron emulsion has a certain therapeutic effect on lipopolysaccharide-induced pneumonia in rats,and its mechanism may be related to reducing the release of cytoinflammatory factor IL-6,IL-10,and TNF-αand alleviating the injury to tissues and organs.
