ABSTRACT
Layer by layer (LBL) methodology essentially targeting polyelectrolytes to form polyelectrolyte multilayers (PEM), possessing good mechanical and chemical properties, has been reviewed in this article. LBL adsorption has been proven to be a facile and flexible technique, catering to the assembly of supramolecular multifunctional matters with a broad range of assembled materials by virtue of diverse interplays such as hydrogen bonding, electrostatic and covalent bonding, etc. The chemical interactions play a prominent role in potential applications of the LBL technique by fabricating novel multifunctional materials from the technological aspect. This paper attempts to emphasize diverse physio-chemical elements associated with the fabrication process of PEMs through the LBL technique. It also provides an insight into molecular dynamics (MD) simulation studies performed to comprehend the underlying physical mechanisms capable of regulating the LBL assemblies

ABSTRACT
Electrospinning, a versatile nanofiber processing technique, has acquired considerable attention over conventional nanofiber fabrication methods owing to its inherent advantages, such as reasonable control over fiber dimensions, scalability, process convenience, and applicability towards an extensive array of materials. Electrospun biodegradable polymer nanofibers based on Poly(vinyl alcohol) (PVA), Poly(β-hydroxybutyrate-β-hydroxyvalerate) (PHBV), Poly(lactic-co-glycolic acid) (PLGA), Polycaprolactone (PCL), and Polylactic acid (PLA) incorporating various biocidal agents for biomedical applications which embodies tissue engineering scaffolds, wound dressing and drug delivery would be addressed here. This review also provides an insight into computational studies of polymers loaded with nanoparticles to examine the interaction studies between them.

ABSTRACT
Any new product that we develop for the world should undergo a life cycle analysis (LCA) from birth to death. Environmental impact can be enhanced by lowering reliance on the resources derived from naphtha. The challenges accompanying the generation of plastic-derived waste can be substantially reduced by employing biodegradable polymers. Green composites have gained significance over traditional petroleum-based products because they are derived from natural resources, environment friendly, recyclable, non-toxic, and biodegradable. In addition, the fabricated composites should exhibit optimized weight and required mechanical properties to meet the performance requirements. Green composites comprise two phases: a bio-based polymer matrix integrated with natural fiber reinforcements like jute, hemp, sisal, flax, banana fiber (abaca), etc. Owing to the inherent benefits of natural fiber reinforcements such as low density (synthetic fibers like carbon and E-glass fibers exhibit density values ranging from 1.8 to 2.1 g/cm3 and 2.54 g/cm3, respectively as opposed to natural fibers spanning from 1.25 to 1.6 g/cm3) and higher acoustic damping in composites, they can be widely used in interior automotive applications. Potential applications in the automotive sector include interior structures such as door panel inserts, armrests, seatback lining, seat bottoms, and under-floor body panels. Green composites formulated from soy protein, polylactic acid (PLA), starch, cellulose, and chitin and along with their processing techniques and applications have been discussed here.

ABSTRACT
Photoactive nanomaterials constitute an emerging field in nanotechnology, finding an extensive array of applications spanning diverse areas, including electronics and photovoltaic devices, solar fuel cells, wastewater treatment, etc. Titanium dioxide (TiO2), in its thin-film form, has been exhaustively surveyed as potential photocatalysts for environmental remediation owing to its innocuousness, stability, and photocatalytic characteristics when subjected to ultraviolet (UV) irradiation. However, TiO2 has some shortcomings associated with a large bandgap value of around 3.2 eV, making it less efficient in the visible spectral range. TiO2 is often consolidated with various carbon nanomaterials to overcome this limitation and enhance its efficiency. Graphene, a 2-dimensional allotrope of carbon with a bandgap tuned between 0 and 0.25 eV, exhibits unique properties, making it an attractive candidate to augment the photoactivity of semiconductor (SC) oxides. Encapsulating graphene oxide onto TiO2 nanospheres demonstrates intensified photocatalytic properties and exceptional recyclability for the degeneration of certain dyes, including Rhodamine B. This review encompasses various techniques to synthesize graphene-based TiO2 photoactive composites, emphasizing graphene capsulized hollow titania nanospheres, nanofibers, core/shell, and reduced graphene oxide-TiO2-based nanocomposites. It also consolidates the application of the aforestated nanocomposites for the disintegration of various synthetic dyes, proving efficacious for water decontamination and degradation of chemicals and pharmaceuticals. Furthermore, graphene-based TiO2 nanocomposites used as lithium (Li)-ion batteries manifesting substantial electrochemical performance and solar fuel cells for energy production are discussed here.

ABSTRACT
Compared to non-degradable polymers, biodegradable polymers are becoming an essential part of the healing of serious bone deformities and have piqued the interest of researchers. Bone is a complex living tissue that has a vital role in locomotion, protects vital organs, and supports and is vulnerable to fractures. Materials used for bone repair should be osteoconductive, osteogenic, and osteoinductive; they should be degraded by hydrolysis and biocompatible. Biodegradable polymers, however, fulfil the properties mentioned earlier; hence become a potential candidate for bone applications.
