About Cover

The cover photo describes the scheme of the twin screw extruder for the preparation of thermoplastic starch (TPS).  As discussed by M. Paula Guarás, this screw extrusion process is very advantageous for the preparation of TPS films with improved mechanical and water vapor absorption properties in any industrial processing line for plastic packaging products.

Abstract

Triclinic LiVPO4F/C composite material is synthesized by Reaction under autogenic pressure at elevated temperature (RAPET) method and for the first time, we have evaluated the electrochemical properties and performance in aqueous electrolyte. Structural and morphological features of the material has been characterized using X-ray diffraction and scanning electron microscopy techniques. The electrochemical properties and performance of the material has been evaluated by using cyclic voltammetry, galvanostatic charge/discharge studies, electrochemical impedance spectroscopic technique and potentiostatic intermittent titration technique. The complete electrochemical studies of LiVPO4F/C composite material has been performed in 0.1M Li2NO3 with 0.05 mL glycerine as an additive in 10 mL of H2O as an aqueous electrolyte and its working mechanism was described using standard three-electrodes as well as two electrode configurations.
