Preparation and electrochemical characterization of magnesium gel electrolytes based on crosslinked Poly(tetrahydrofuran)
نویسندگان
چکیده
A crosslinked poly(tetrahydrofuran) (c-PTHF) was synthesized as a novel polymer matrix for gel electrolyte (GPE) swelled with Mg(TFSI)2/triglyme solution to develop Mg-ion battery. Two GPE based on c-PTHF different crosslinking structure and crosslinker ratio were obtained free-standing membranes excellent heat resistance. From the CV measurement, Pt/GPE/AZ31 cell clearly showed Mg redox reaction, values of current densities in reduction/oxidation peaks Coulombic efficiency larger than those triglyme solution. This may be due changes solvation Mg2+ ions by presence structures network framework.

Electrochemical Preparation and Characterization of Mn5O8 Nanostructures
Electrochemical synthesis followed by heat-treatment is a facile and easy method for preparation of nanostructured metal oxides. Herein we report nanostructured Mn5O8 prepared through pulse cathodic deposition followed by heat-treatment for the first time. For the preparation of Mn5O8 nanorods, pulse cathodic electrodeposition was first done from 0.005M Mn(NO3)2 at the current density of 5 mA c...

Background: Nowadays transdermal drug delivery systems (TDDS), as an appropriate replacement for oral and parenteral dosage forms, are developing. These systems which designed to transport drugs through skin layers into the systemic circulation, have several benefits such as avoiding first-pass metabolism, sustained and controlled drug release, reducing side effects, and ease of use. The aim of...
