    Thermoelectric generators act as renewable energy sources
    (Elsevier Ltd, 2021) Mamur H.; Dilmaç Ö.F.; Begum J.; Bhuiyan M.R.A.
    The thermoelectric generator (TEG) is a solid-state energy converting device that converts heat directly into electrical energy. TEGs are silent, scalable, and reliable, as they have no moving parts. The consciousness of surroundings pollution correlated with global warming has resulted in an upsurge of technological research to develop eco-friendly energy resources. TEG employs waste heat to generate power and thus can be the termed eco-friendly energy source. In the economic aspect, waste heat is a free source for generating electrical energy. It can handle the heat generated by the human body, computer chips, automobile engines, and industrial utilities. TEG used as a renewable energy source has been presented in this review article. It would help in the development of establishing a low-power solution and high-performance system. The present status, prospect, and update information about the TEG used as a renewable energy source has been discussed in detail. This review article also provides a recommendation, which system would be suitable for electrical energy generation by TEG through renewable energy resources. © 2021 Islamic University

    A review on performance evaluation of bi2te3-based and some other thermoelectric nanostructured materials
    (Bentham Science Publishers, 2021) Bhuiyan M.R.A.; Mamur H.; Dilmaç Ö.F.
    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 still has 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 mate-rial, 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. © 2021 Bentham Science Publishers.

    Opportunities for thermoelectric generators in supporting a low carbon economy
    (ICE Publishing, 2022) Bhuiyan M.R.A.; Mamur H.; Dilmaç Ö.F.; Üstüner M.A.
    Environmental pollution, global warming and increasing energy demands are urgent challenges facing society. Governments all over the world have set a national policy target for the transition to a zero or low carbon dioxide economy. As a result, scientists and engineers in industry and academia are working to develop cleaner, alternative and sustainable energy production technologies. One technology that has potential in this green technology transition is thermoelectric generators (TEGs), traditionally used off-grid and isolated from things such as stand-alone solar-thermal cells for military and aerospace applications such as missile-testing systems and space telescope cameras. However, future applications based on home entertainment, security systems and smart metering applications are imminent. Key limitations to this are low efficiency, high costs and self-heating with low thermal conductivity. Hence, this study aims to examine the current state of the art of TEGs and identify future research directions to achieve support for the green technology transition. The key findings of this study show that present successes will fulfill the future advancement of thermoelectric technology by supporting a low carbon dioxide economy. © 2022 ICE Publishing: All rights reserved.

    Zinc Oxide Nanomaterials for Biomedical Applications
    (Bentham Science Publishers, 2023) Bhuiyan M.R.A.; Mamur H.; Dilmaç Ö.F.
    Semiconducting metal oxide nanomaterials are the future potential materials for biomedical applications. Zinc oxide (ZnO) nanomaterials are developed by using the organic synthesis process for excellent biocompatibility, selectivity, sensitivity, good chemical stability, non-toxicity, and fast electron transfer properties. They have a high surface-to-volume ratio that performs proper contouring on the human body to feel comfortable. Recent advanced studies on these nanomaterials show that they are promising materials for effective antibacterial and antifungal agents against a variety of microbes. They also promise to provide advanced technology for biomedical applications that can be used to destroy several types of malignant cells in the human body. Moreover, they can be used as antibacterial agents in the human body. This chapter briefly discusses the cost-effective approach to organically synthesizing ZnO nanomaterials. Moreover, these ideas can be developed to characterize these materials as biomaterials to perform easily upscaled in biomedical applications. © 2023 Bentham Science Publishers.
