Futuristic Perspective Analysis of Online Buyers for Sustainability of E-commerce

In the global competitive business world, utilization of modern and innovative technological practices in business transactions is inevitable. E-commerce is a paradigm shift to connect customers electronically in the present business system. E-commerce covers electronic transmission of information, monetary payments and physical delivery of products. It is a pertinent time to analyse the future potentiality of e-commerce and the perception of online buyers who use this platform. A study was conducted with the following objectives: to describe the perception of online buyers, to make online buyers’ Futuristic Perspective Analysis (FPA) of e-commerce and to study factors influencing sustainability of e-commerce in the future. The data were collected from primary and secondary sources. A primary survey was conducted through structured questionnaire administered on select online buyers in Karaikal, Union Territory of Puducherry, India. The collected data were analysed with multivariate statistical tools like factor analysis and multiple regression analysis with SPSS. The findings were presented with suitable suggestions to know the futuristic perspectives of online buyers and the sustainability of e-commerce

A Critical Review on Hygrothermal and Sound Absorption Behavior of Natural-Fiber-Reinforced Polymer Composites

Increasing global environmental problems and awareness towards the utilization of eco-friendly resources enhanced the progress of research towards the development of next-generation biodegradable and environmentally friendly material. The development of natural-based composite material has led to various advantages such as a reduction in greenhouse gases and carbon footprints. In spite of the various advantages obtained from green materials, there are also a few disadvantages, such as poor interfacial compatibility between the polymer matrix and natural reinforcements and the high hydrophilicity of composites due to the reinforcement of hydrophilic natural fibers. This review focuses on various moisture-absorbing and sound-absorbing natural fiber polymer composites along with the synopsis of preparation methods of natural fiber polymer composites. It was stated in various studies that natural fibers are durable with a long life but their moisture absorption behavior depends on various factors. Such natural fibers possess different moisture absorption behavior rates and different moisture absorption behavior. The conversion of hydrophilic fibers into hydrophobic is deemed very important in improving the mechanical, thermal, and physical properties of the natural-fiber-reinforced polymer composites. One more physical property that requires the involvement of natural fibers in place of synthetic fibers is the sound absorption behavior. Various researchers have made experiments using natural-fiber-reinforced polymer composites as sound-absorbing materials. It was found from various studies that composites with higher thickness, porosity, and density behaved as better sound-absorbing materials

Synthesis of Ultra‐fine Co 1‐(x+y) Ni x Zn y Fe 2 O 4 Ferrite Nanoparticles: Customizing Magnetic Properties

Synthesis of ultrafine Co₁-(x+y)NixZnyFe₂O₄ magnetic nanoparticles with different chemical compositions is essential to study the magnetic fluid hyperthermia (MFH) as a treatment in which the superparamagnetic behaviour of materials is beneficial. In this paper, Co₁-(x+y)NiZnyFe₂O₄ magnetic nanoparticles with different x and y amounts were synthesized to find out a tuning pattern for magnetic properties, especially anisotropy constant to gain the best heating efficiency. We proved that the co-presence of ions will greatly affect the magnetic performance of our superparamagnetic nanoparticles in which Co₀.₅₉Zn₀.₄₁Fe₂O₄ for values of x = 0.00 and y = 0.41 exhibits the highest magnetic anisotropy constant after CoFe₂O₄. This success in customizing magnetic properties to reach high magnetic properties by using less toxic materials might be another good starting point for researchers to focus more on their possible applications
