A STUDY ON THE PROBLEMS FACED BY THE COLLEGE STUDENTS IN THEIR ONLINE SHOPPING

Online shopping - an wonderful invention, in which the consumers can directly buy goods or services from a seller in real time with the help of online shopping mechanism, with no intermediary service, over the Internet . It is also known as online shop, e-shop, e-store, internet shop, webshop, webstore, online store, or virtual store. It is a form of electronic commerce where in the sale or purchase transaction is completed electronically and interactively in real -time. Recently, a large percentage of electronic commerce is conducted entirely in electronic form. This process is called Business – to – Consumers (B2C). Online retailers are also known as e-tailers and online retail is sometimes known as e- tail. Almost all big retailers are now electronically present on the World Wide Web. Online shopping, such an easy way of doing shopping mechanism provides the changed face of retailing to the shoppers. Initially, the consumers very well go through the websites of the stores before travelling to the stores to purchase. Later, now, many shoppers are just bypassing the direct visit store and order for the required products or services through online directly from the websites. Even with all the great efforts of online stores to improve their system or mechanism, there are few problems that the consumers still have to face while their online shopping. This paper aims to analyze the issues in online shopping system

A study on adsorption of gases in the thin film nanocomposites

Separation of greenhouse gases through polymeric thin film by the selective transport of gas are immense advantages such as light weight, economical, high process flexibility and less space requirement. The thin film technology is used in post combustion process as well as pre combustion processes. This thin film mixed matrix composites (MMC) is prepared using inorganic nanofiller and polymer matrix. In this study, the effect of Lanthanum Oxide (La2O3) nanofiller on the N2 gas adsorption properties of polysulfone (PSf) composite is reported. The solvent evaporation technique is used for synthesizing the film composite. To complete the polymerization of the thin film, the film kept in oven at 90°C for 210 minutes. The morphology of the thin film composite is investigated by Field Emission Scanning Electron Microscope (FESEM) and the chemical structure of the composite is also confirmed through Fourier transform infrared spectroscopy (FT-IR). The performances of the thin film on adsorption are characterized by gas adsorption techniques in measurement of N2 gas. The La2O3 thin film composite significantly improved (31%) N2 gas adsorption when compared to the neat thin fil
