A stable magnetic nanocomposite of collagen and superparamagnetic iron oxide nanoparticles (SPIONs) is prepared by a simple process utilizing protein wastes from leather industry. Molecular interaction between helical fibers spherical SPIONs proven through calorimetric, microscopic spectroscopic techniques. This exhibited selective oil absorption tracking ability, allowing it to be used in removal applications. The environmental sustainability the adsorbed nanobiocomposite also demonstrated...
We report large-scale biosynthesis of copper nanoparticles using an extract henna leaves as reductant. Due to the substantial electrical conductivity calcined nanoparticles, we used them prepare conductive nanobiocomposites utilizing collagen waste. demonstrate that nanobiocomposites, when inserted between batteries, illuminate a light emitting diode lamp.
Leather processing has emerged as an important economic activity in several developing countries. Awareness of environmental problems increased considerably and during recent years protecting environment become a global issue. Currently the leather industry is going through phase change due to regulations. The article summarizes current methods with their rationale problems. It been revealed that pretanning tanning processes contribute 80–90% total pollution load (BOD, COD, TS, TDS, Cr, S2−,...
Graphene is an intriguing two-dimensional material, which could be modified for achieving tunable properties with many applications. Photoluminescence of graphene due to plasmonic emission well-known, however, attempts develop strong luminescent have been difficult. Synthesis a graphene-based material dual optical functionality, namely quenching the fluorescence organic dyes while maintaining its own self-luminescence, interesting and challenging proposition. Here, we demonstrate this...
Chromium-containing wastes from various industrial sectors are under critical review. Leather processing is one such activity that generates chromium-bearing in different forms. One of them chrome shavings, and this contributes to an extent 10% the quantum raw skins/hides processed, amounting 0.8 million ton globally. In study, high protein content shavings has been utilized for reduction chromium(VI) preparation tanning agent. This approach exploited development two products: with alone as...
Leather industry produces huge quantities of bio-waste that can be used as raw material for the bulk synthesis carbonaceous materials. Here we report multifunctional carbon nanostructures from pristine collagen wastes by a simple high temperature treatment. Our studies reveal nanocarbons derived have partially graphitized structure with onion-like morphology and are naturally doped nitrogen oxygen, resulting in properties. This synthetic route provides cost-effective alternative to existing...
Abstract Management of burn wounds with diabetes and microbial infection is challenging in tissue engineering. The delayed wound healing further leads to scar formation severe injury. Herein, a silver‐catechin nanocomposite tethered collagen scaffold angiogenic antibacterial properties developed enable scarless chronic infected Pseudomonas aeruginosa under diabetic conditions. Histological observations the granulation tissues collected from an experimental rat model show characteristic...
Sustainability of the leather industry demands a paradigm shift from existing chemical-based processing to bio-based degradable systems. Enzyme-based unhairing systems are evolving as an eco-friendly alternative sodium sulfide- and lime-based conventional process. However, factors such uncontrolled enzyme activity over skin thus resulting in poor quality leather, cost, recyclability limit their commercial exploitation. To overcome these challenges, herein, we synthesized zinc-based metal...
The main purpose of the seed industry is to cater seeds with desired strength and viability, for which coating a basic requirement. Herein, hybrid an electrosprayed protein (collagen) on electrospun nanofibers having multidentate zinc-reinforced carbohydrate (pectin)/PVA composite (PVA/Pec/Zn/Col-NF) was developed. zinc ensured covalent binding -OH in pectin/PVA addition native galvanic between polymers. Along this, hydrogen bonding interactions -NH2 groups collagen PVA/pectin further...
A bifunctional luminomagnetic ≈30 nm Gd1-xEuxVO4 nanophosphor is synthesized using a facile sol–gel method. The observed to produce both paramagnetic behavior and highly efficient red emission peaking at 618 nm. Probing the photoluminescence, time-resolved spectroscopy, magnetization measurements, cytotoxicity assay reveal its suitability for biological applications, in particular, cell labeling high-contrast imaging.
