Senegal has adopted a local legislative and regulatory framework to protect the environment and achieve sustainable development goals. Different strategies and legal texts are available. The country has also signed many sub-regional regulations and international conventions. Green Chemistry is taken into account in many laboratories at Cheikh Anta Diop University. In national and international research centers, fundamental and applied researches that follow some principles of Green Chemistry are conducted in agriculture, food technology, and the environment. Some projects are also in progress in these domains. In the industry area, even though some environmental regulations are followed, the practice of green chemistry is rather not widespread, because mainly of unfamiliarity and of routine work. However, Senegal benefits from its membership of IUPAC, and participates in major global forums dealing with green chemistry.
Computational techniques encompass all informatic tools that extract information from large databases. Some remarkable applications include chemoinformatics, geoinformatics, and bioinformatics, involving advanced computing tools to explore and analyse chemical, geological and biological data. Mass spectrometry has provided tremendous input regarding useful instrumentations that enhance the relevance of computational methods. Here, we reviewed computational methods for advanced mass spectrometry particularly the OMIC which comprises of technologies that measure some characteristics of a large family of cellular molecules, such as genes, proteins and small metabolites.
Vegetable oils are being considered as bio-based transformer liquid alternatives due to their biodegradability and potential for environmental impact reduction. Considering the depletion of mineral oils due to their petroleum-based origins, it appears that bio-based liquids could be viable alternatives for transformer applications. These liquids also show promise for a variety of other electrical and heat transfer applications, such as capacitors, cables, circuit breakers, and tap changers. They are derived from a variety of plants, have cost benefits over synthetic oils and are plentiful in many places. Although bio-based liquids have many benefits, they also have limitations. This includes poor thermo-dielectric performance. Adding nanoparticles to bio-based liquids at the right concentration can address these issues. Although there has been significant progress in research and development regarding the use of nanoparticles in bio-based liquids, no single type of nanoparticle has consistently proven to outperform others in all aspects. This review explores techniques for increasing the efficacy of bio-based liquids by incorporating nanoparticles to form bio-based liquid nanocomposites. It covers contemporary experimental studies on bio-based liquid nanocomposites, including preparation, stability tests, thermal characteristics, and dielectric characteristics. Furthermore, clarifies the fundamental principles that underpin the observed findings in this promising topic. This review seeks to contribute to the growing body of research on bio-based liquid nanocomposites in the field of transformers.
This paper explores the energy absorption capacity of biocomposites and its impact on sustainability and environmental benefits. Biocomposites consisting of natural fibers within a polymer matrix have attracted attention for their potential to improve impact resistance and safety while reducing environmental impact. This review critically examines the current state of research in this field, highlighting the importance of biocomposites in utilizing renewable and recyclable resources, energy-efficient processing, minimizing toxicological impacts, and promoting responsible waste management. This also highlights the importance of assessing emissions, including volatile organic compounds and nanoparticles, from an environmental and toxicological perspective. Additionally, the paper takes into account the degradation susceptibility of sustainable biocomposites, emphasizing the need to ensure their structural integrity during their service life and their ultimate biodegradability and assimilability during composting. The results presented in this review highlight the multifaceted advantages of biocomposites, making them a promising choice for sustainable materials with excellent energy absorption capabilities.
Researchers are increasingly concentrating on the development of polymer composite materials for electronic applications, transitioning from synthetic polymers to biopolymers in response to escalating environmental concerns over waste management. Nonetheless, polymeric materials exhibit worse electrical characteristics and device longevity compared to inorganic semiconductors and metal conductors. Consequently, several researchers have explored the use of graphene and nanocellulose, along with the hybridization of these materials, to enhance the composites properties. This review article examines the use of graphene and nanocellulose in biopolymer composites, as well as the hybridization of graphene with nanocellulose to enhance biopolymer composites, highlighting its prospective advantages in electrical applications. This paper also explores the applications of these composites in the field of electronics, along with the latest advancements in their fabrication techniques. This review study offers researchers insights into the use of graphene and nanocellulose, as well as their hybridization in composites for electrical applications.
