The growth of carbon nanostructures from vegetable oils using a modified conventional approach is a simple and environmentally friendly technology with controllable features. The goal of this study is to develop a simple and environmentally friendly process for making carbon nanoparticles using commercially available, low-cost vegetable oils. The technique involves the controlled burning of “Mustard”, “Olive”, and “Linseed” oils using the traditional clay lamps and collecting the carbon soot on a ceramic plate. The prepared carbon nanoparticles were purified through sonication and subjected to characterization using powder X-ray diffraction, SEM, Fourier transformed infrared, Thermogravimetric and differential scanning calorimetric analyses. The average particle size of carbon nanoparticles as investigated by powder X-Ray Diffraction analyses was found to be 18, 24, and 57 nm for mustard, olive and linseed oils respectively. SEM analyses revealed the surface morphology of these carbon nanostructures as spherical particles. Thermogravimetric analysis (TGA) and Differential Scanning Calorimetry (DSC) providing knowledge about the thermal stability of these carbon nanoparticles. The synthesized carbon nanoparticles were screened for antibacterial activities against different species (e.g., Pseudomonas aeruginosa, Streptococcus haemolyticus, Proteus refrigere and Staphylococcus aureus) and fruitful results have been obtained.

Acrylates are esters of acrylic acid formed by the reaction of acrylic acid with alcohols. These acrylic esters were produced by polymerization of combination with different acrylic monomers to produce the materials with enhanced characteristics for coating applications. The acrylate-based polymers were prepared by varying the nature and ratios of the monomers. Moreover, the properties of the polymeric materials were further improved by compositing with the nano-fillers i.e. carbon nanotubes. Further, the materials were coated on different surfaces to evaluate the coating characteristics by standard analytical procedures. Composition and morphology of the materials were characterized by different spectroscopic techniques. Polyacrylate based polymers were synthesized by step growth polymerization using different types of monomers moieties (5 different types of acrylic monomer along with one functional monomer and an aromatic monomers) to enhance coating properties and to enhance dispersion of carbon nanotubes. Characterization was done by FTIR (Fourier Transform Infra-Red) and UV-Vis spectroscopy. Study of polymeric coating was done on different surfaces by different techniques like Barcol Hardness, Gloss Test, Salt Spray Test, Cross Hatch Test and Mandrel Dent Measurement as given in standard ASTM methods. The results revealed better adhesion, crack resistance, and abrasion resistance. The graphical abstract is given below as Fig-1.
