Fuel cells are the energy conversion devices that can convert the chemical energy of fuel into electrical energy efficiently and, more importantly, in a greener way by utilizing air as an oxidant. Solid polymeric electrolyte membrane is one of the major parts of the fuel cell device, which selectively allows the passage of protons while blocking the flow of electrons through it and makes the device functional. Till date, Nafion® is the m Read More

The research on the application of multiferroic and magnetoelectric materials has gained momentum recently due to the exciting technological applications offered by the coupling between magnetic and electric order. In this article, an extensive review of patents on the application of multiferroic and magneto electric materials is presented. Beginning with an introduction, a brief idea of the magneto electric effect is gi Read More

Multiferroic materials which display the coexistence of ferromagnetism (FM) and ferroelectric (FE) polarization have drawn considerable attention due to their fundamental physical characteristics and potentially wide applications including tunable microwave devices. In a multiferroic material system, due to the mutual coupling of the ferroelectric and ferromagnetic order, an applied magnetic field can alter the dielectric polari Read More

In the domain of magneto transport properties of materials, giant magnetoimpedance (GMI), is of research interest as it represents a large change of both real and imaginary parts of the impedance under a static magnetic field applied. Understanding of GMI needs the understanding of the micro magnetic characteristics of the materials and its dependence on dynamic magnetism. After early observation of GMI in soft magn Read More

This manuscript reviews the recent patents and literature on the development of sustainable resource based polymer blends. In recent years, much attention has been focused on the research to replace petroleum-based polymers with renewable resource based materials that exhibit competitive mechanical properties. A great deal of work is focused on polymer blends to understand the mixing dynamics at the molecu Read More

Enhancing the optical transmission of ZnO film is an important topic for its application. This work presents the manufacture and potential application of the ZnO materials containing various dopants in recent literatures and patents and then focuses on the comparison of optical properties of Al- and Mo-doped and codoped ZnO films. The films were deposited on quartz glass substrate by a sol-gel process, and ch Read More
