In the present study, an attempt has been made to utilize the natural plant dye extracted from petals of Euphorbia pulcherrima (locally called as Lalupate) via green techniques using water as solvent at boiling condition, for fabrics dyeing in combinations with natural mordants such as Aloe vera, Marcha (traditional yeast used in fermentation), and...

The objective of this research is to employ the natural dyes in dye-sensitized solar cell (DSSC). On account of eco-friendly, renewable, and non-hazardous properties of natural dyes over silicon, a semiconductor, photo-sensitizer in conventional solar cells, cyclohexane extract of Terminalia alata, a natural dye, was employed as photo-sensitizer. T...

Hypericum cordifolium is a medicinal plant traditionally used for the treatment of the menstrual disorder, backache, dislocation of bone, fever, diarrhea and dysentery due to the presence of potential bioactive secondary metabolites. Ethanolic extract of dried leaf powder was prepared using the Soxhlet apparatus, followed by qualitative phytochemic...

The extent of methicillin-resistant Staphylococcus aureus (MRSA) in children is still unknown. The collected wound pus samples were processed. Identification of S. aureus was done according to standard microbiological procedures as per the clinical laboratory standards institute (CLSI) guidelines (2016). The antibiogram of the isolates was carried...

Present work explains the synthesis of urea–formaldehyde composites with Allo (Girardinia diversifolia) and cotton (Gossypium arboreum) fibers. Urea–formaldehyde resin was synthesized by condensation polymerization of urea and formaldehyde monomers. Cellulose fibers were extracted by various chemical treatments of natural fibers. Composites were pr...

Wood flour (WF) reinforced polypropylene (PP) composites were studied with special attention to morphology and mechanical properties of the composites and the effectiveness of chemically modified fillers to improve their mechanical properties. The composites of polypropylene with neat wood flour and treated wood flour of Sorea robusta in different...

The aim of this work is to study the morphological changes after alkali treatment and functionalisation of cellulosic materials present in crude bamboo and sisal flours using ionic liquid as solvents. The flours of bamboo (BF) and sisal (SF) were subjected to acetylation and silylation using acetic anhydride (AA) and hexamethyldisilazane (HMDS) as...

In this paper, the bamboo flour (BF) reinforced polypropylene (PP) composites were studied with special attention to morphology of the composites and the effectiveness of chemically modified fillers to improve their mechanical properties. The composites of polypropylene with neat bamboo flour (BF) and treated bamboo flour (TBF) in different proport...

Aiming at development of completely biodegradable composite materials based on locally available low-cost bamboo flour (BF) as filler, structure properties correlations in aliphatic–aromatic copolyester/BF composites fabricated by melt mixing have been studied by means of different techniques such as electron microscopy, X-ray diffraction, tensile...

Continuous depth sensing indentation microhardness measurements were performed to investigate the effect of filler content and dimensionality on the mechanical behaviour of different polymer nanocomposites. In 1D filler reinforced nanocomposites (such as PP/MWCNT system), both the hardness and the indentation modulus were found to appreciably incre...

The comparative studies on the thermal, mechanical and morphological behavior of compression molded poly(propylene) (PP)/wood flour (WF) composites were performed using wood flours (WFs) of different origins. The comparison has been made on the basis of results obtained from thermogravimetric analysis (TGA), differential scanning calorimetry (DSC),...
