About Cover

Electric vehicles have seen steady development and growth over the last half-decade. The integration of modern technologies like Artificial Intelligence and Machine Learning leading the advancements in the lives and durability of batteries and their efficiency. With each passing year, electric mobility is seeing new heights. And more than 2 million electric vehicles started running on the road which is a record for a calendar year. If the current trends continue, the number of electric vehicles that would be sold in the year 2030 could be as high as 43 million. The cover photo of this November 2019 issue is inspired by the editorial article written by Dr. Ashutosh Tiwari on Current Global Scenario of Electric Vehicles.

Abstract

ZnO nanorods (ZnO) are grown by Chemical Bath Deposition on microfiltration polyetheresulphone (PES) water membranes in order to combine photocatalytic properties of zinc oxide to adsorption properties of membranes. Degradation of a model dye (methylene blue, MB) dispersed in water is promoted by exposition of multifunctional ZnO/PES membranes to UV and solar light: in fact, ZnO decorated membrane ensures generation of reactive oxygen species (ROS) that degrade the organic pollutants dispersed in water. ZnO degradation promoted by UV irradiation is detectable by anionic meso-tetrakis(4-sulfonatophenyl) porphyrin (H2TPPS4-) that is used as effective molecular probe to sense the presence of Zn2+ ions due to photocatalytic leaching. © VBRI Press.
