“…Fe 3 O 4 -coated Si (Fe 3 O 4 @SiO 2 ) is a common MNP used in enzyme immobilisation. Based on former findings from studies on the transesterification of olive oil over Burkholderia lipase immobilizsd on an alkyl-functionalized Fe 3 O 4 @SiO 2 catalyst [210,211], high conversion of biodiesel (90%) is achieved using 11 wt.% catalyst for 30 h reaction time. Similarly, P. cepacia lipase immobilised on MNPs achieved a high conversion (79%) of biodiesel [212], whereas Thermomyces lanuginosus lipase immobilised on Fe 3 O 4 achieved a high conversion (97%) of palm oil transesterification.…”

Biodiesel, comprising mono alkyl fatty acid esters or methyl ethyl esters, is an encouraging option to fossil fuels or diesel produced from petroleum; it has comparable characteristics and its use has the potential to diminish carbon dioxide production and greenhouse gas emissions. Manufactured from recyclable and sustainable feedstocks, e.g., oils originating from vegetation, biodiesel has biodegradable properties and has no toxic impact on ecosystems. The evolution of biodiesel has been precipitated by the continuing environmental damage created by the deployment of fossil fuels. Biodiesel is predominantly synthesised via transesterification and esterification procedures. These involve a number of key constituents, i.e., the feedstock and catalytic agent, the proportion of methanol to oil, the circumstances of the reaction and the product segregation and purification processes. Elements that influence the yield and standard of the obtained biodiesel encompass the form and quantity of the feedstock and reaction catalyst, the proportion of alcohol to feedstock, the temperature of the reaction, and its duration. Contemporary research has evaluated the output of biodiesel reactors in terms of energy production and timely biodiesel manufacture. In order to synthesise biodiesel for industrial use efficaciously, it is essential to acknowledge the technological advances that have significant potential in this sector. The current paper therefore offers a review of contemporary progress, feedstock categorisation, and catalytic agents for the manufacture of biodiesel and production reactors, together with modernised processing techniques. The production reactor, form of catalyst, methods of synthesis, and feedstock standards are additionally subjects of discourse so as to detail a comprehensive setting pertaining to the chemical process. Numerous studies are ongoing in order to develop increasingly efficacious techniques for biodiesel manufacture; these acknowledge the use of solid catalytic agents and non-catalytic supercritical events. This review appraises the contemporary situation with respect to biodiesel production in a range of contexts. The spectrum of techniques for the efficacious manufacture of biodiesel encompasses production catalysed by homogeneous or heterogeneous enzymes or promoted by microwave or ultrasonic technologies. A description of the difficulties to be surmounted going forward in the sector is presented.

“…Likewise, nanorods are 1-D nanomaterials and are composed of diverse materials as ceramics, metals, or carbon (Ghassan et al, 2019). Due to their aspect ratio, nanorods display a chemical, electrical, magnetic, and optical anisotropy, which allows a different interaction with biomolecules or cells (Bauer et al, 2004).…”

Over the past years, biomaterials-based nano cues with multi-functional characteristics have been engineered with high interest. The ease in fine tunability with maintained compliance makes an array of nano-bio materials supreme candidates for the biomedical sector of the modern world. Moreover, the multi-functional dimensions of nano-bio elements also help to maintain or even improve the patients’ life quality most securely by lowering or diminishing the adverse effects of in practice therapeutic modalities. Therefore, engineering highly efficient, reliable, compatible, and recyclable biomaterials-based novel corrective cues with multipurpose applications is essential and a core demand to tackle many human health-related challenges, e.g., the current COVID-19 pandemic. Moreover, robust engineering design and properly exploited nano-bio materials deliver wide-ranging openings for experimentation in the field of interdisciplinary and multidisciplinary scientific research. In this context, herein, it is reviewed the applications and potential on tissue engineering and therapeutics of COVID-19 of several biomaterials. Following a brief introduction is a discussion of the drug delivery routes and mechanisms of biomaterials-based nano cues with suitable examples. The second half of the review focuses on the mainstream applications changing the dynamics of 21st century materials. In the end, current challenges and recommendations are given for a healthy and foreseeable future.

“…Since of their attractive physical and chemical properties, carbon has drawn considerable attention over the last few decades. To date, such nanoparticles as carbon 1 , nanotubes 2 , ions 3,4 , nanowires 5 , nanofibers 6 and carbon nanorods 7,8 have been recorded. Such carbon nanometer materials are supposed to have a fairly large bandgap and to behave like a semiconductor.…”

“…In particular, for the treatment and separation of the emulsified oil-water mixture, MNPs obtained from this process have been well utilised. Fe 3 O 4 MNPs is synthesised via the solvothermal pathway 7 to split up the emulsified oil-water mixture and to differentiate water and oil into phases. Dissolving 1.62 g of FeCl 3 .6H 2 O, 0.48 g of trisodium citrate dihydrate, and 4.32 g of NaAc in 60 mL of ethylene glycol and subjecting the mixture to vigorous agitation at room temperature is a synthetic technique for the formation of Fe 3 O 4 MNPs.…”

Nanorod technology has gone a long way in the field of science and to a great extent, it has been a dictator of the past, present, and future of technology work. This article shows a detailed explanation of the course of nanorod production and the application from start to finish. Various kinds of nanorods have been found to exist and they have been maximally put to good use in different fields of life. These nanorods, however, did not just come into existence, some of them were formed from some nanorod compounds while some other ones came into being as a result of the combination of two or more compounds. These particles in their raw form can be generally useful, but its specific functions cannot be gotten without proper optimization. Various researchers have, dedicated their time to proper optimization of the numerous nanorods that are available in order to find an optimum result science. This course scans through the birth, processing as well as the highly valued application of nanorods.
