Toyota and colleges discover new electrolytes to improve battery performance

图片
Abstract: Monash University and Toyota North American Institute have discovered a new liquid salt-based electrolyte that can be used in batteries. It is non-volatile, non-flammable and electrochemically stable, eliminating flammability and improving its stability, resulting in high energy. Density battery performance can be improved. According to reports, Toyota North American Research Institute (TRINA) and Monash University in Australia have discovered a new liquid salt-based electrolyte that can be used in batteries. It is non-volatile, non-flammable and electrochemically stable. The flammability and stability are improved so that the performance of the high energy density battery can be improved. The Toyota North American Institute is located in Ann Arbor, Michigan and is part of the Toyota North American R&D Center (TMNA). Professor Doug Mac Farlane of the Monash University School of Chemistry said: "We also found that these new electrolytes can be used in rechargeabl...

Biodegradable betaine-based aprotic task-specific ionic liquids and their application in efficient SO2 absorption

图片
Utilization of cheap and natural resources is an important topic in green chemistry. A new class of betaine-based aprotic task-specific ionic liquids (ILs), including [C 4 bet][TFSI], [C 4 bet][DCA], [C 4 bet][SCN], [1O2bet][TFSI], [1O2bet][DCA], [2O2bet][TFSI], and [2O2bet][DCA], has been designed and prepared through a new ionic liquidization strategy from the renewable natural resource betaine. Their physicochemical characteristics, including spectral properties, density, viscosity, melting point, glass transition temperature, thermal stability, conductivity and electrochemical window, have been comprehensively studied. They were first applied as new absorbents for SO 2  capture, and [C 4 bet][SCN] exhibited the maximum absorption capacity of 0.93 mol SO 2 /mol ILs at 20 °C and 1 atm (SO 2 /N 2  = 10% vol.) with rapid absorption rates in 21 min. Moreover, the effect of temperature, pressure, and water content on the absorption performance of SO 2  was investigated. T...

CoO@Co and N-doped mesoporous carbon composites derived from ionic liquids as cathode catalysts for rechargeable lithium–oxygen batteries

图片
The catalytic activity of a cathode material plays a vital role in determining the electrochemical performance of Li–O 2  batteries. Herein, N-doped mesoporous carbon-supported CoO@Co nanoparticles are prepared  in situ using the ionic liquid (IL) 1-butyl-3-methylimidazolium tetrachlorocobalt ([BMIm] 2 [CoCl 4 ]) as the precursor with silica as the hard template. The material was characterized by TGA, BET, XRD, TEM, XPS, and H 2 -TPR. After exposure to air, the species on the surface of the Co is CoO, as verified by XPS. The pore size is about 2 nm, and the CoO@Co nanoparticles were irregularly shaped and sized in the range of 20–300 nm, which may have been due to the aggregation of ultrafine nanoparticles. The existence of an interaction between the CoO@Co nanoparticles and the N-doped support is confirmed by XPS and H 2 -TPR. The catalyst shows superior activity for oxygen evolution reaction (OER) manifested in its lower charge potential (3.75 V at the current density of 1...

FTIBAMZONE CAS:210165-00-7

This product is an antiviral drug. It has anti-Chlamydia trachomatis and anti-herpesvirus activity. Its mechanism of action is mainly to inhibit viral DNA and early protein synthesis. Not only does it inhibit the herpesvirus type II DNA polymerase, but it does not directly inactivate the herpes virus. This product has a certain antifungal effect on dermatophytes. It is the first anti-sandwich drug in China. It has been proven to be an effective antiviral drug. It has the effects of shortening the course of disease and relieving pain for various viral infections, and has the characteristics of strong activity, low toxicity and rapid effect. It is 100% effective for herpes simplex and herpes zoster; 70% cure for recurrent herpes simplex, 93% effective; especially for condyloma acuminata caused by human papillomavirus; inhibiting Chlamydia trachomatis at a concentration of 0.5~1μg The effect is 10 times stronger than chlortetracycline.
