A review on performance evaluation of Bi2Te3–based and some other thermoelectric nanostructure materials

Background: Future sustainable energy industrialization is a green energy source that has a lower circumstantial impact than traditional energy technologies. The advancement of new energy generation is important to expand the share of renewable energy sources. Objective: Worldwide, for the next generation, future energy demand may be fulfilled by using one of the renewable energy sources such as thermo electricity. Methods: The bismuth telluride-based (Bi2Te3-based) nanostructure material in thermo electricity stillhas a major part of applications. It is known as the most prospective TE device manufactured from a research arena towards successful commercialization. Results: The Bi2Te3-based nanostructure material is now on commercialization stages that it has some limitations. In order to find out the future direction of research and development of this material, the material will face a challenging way. Conclusion: The review paper provides an effective approach to overcome the limitation of Bi2Te3-based nanostructure. Moreover, in this review paper, the performance evaluation with existing Bi2Te3-based nanostructure and some other TE materials will be discussed in detail.

A facile and simple approach to synthesis and characterization of methacrylated graphene oxide nanostructured polyaniline nanocomposites

A novel, scalable methacrylated graphene oxide (MeGO) nanostructured polyaniline (PANI) nanocomposite was synthesized and electrodeposited on the surface of fluorine-doped tin oxide electrode (FTOE). The two-dimensional support maintained a suitable substrate and arrayed in a conductive polymer matrix, creating an ultra-superconductive platform with extraordinary characteristics. The versatility of the nanocomposite performance was corroborated by altering the amount of MeGO coated on FTOE and changing the charge density of electro-polymerized PANI on the substrate. This exceptional nanostructure material enabled a robust platform design that demonstrated the extraordinary performance with enhanced conductivity and stability. Charge transfer resistance (Rct) was dramatically decreased from 11,000 (for bare FTOE) to 65 (for MeGO/PANI).

Mechanically robust, UV screener core–double-shell nanostructures provide enhanced shielding for EM radiations over wide angle of incidence

Herein, first, of its kind core–double shell nanostructure material were synthesized in which ferrite (Fe3O4) acts as a diffused shell around conducting core (carbon nanosphere, CNS) separated by a dielectric spacer SiO2 for various applications.
