We proposed a novel approach to prepare high-performance continuous regenerated keratin fibers with wool-like structure by using the cortical cells and linear from wool waste as reinforcement adhesive, respectively. The spindle-shaped were taken based on different responses of mesenchyme in treatments H2O2 oxidation ultrasonication. was yielded through dissolving green solution consisting starc...

The objective of the project is to examine the potential use of wool as an industrial and/or laboratory adsorbent. This will be carried out by examining the metal sorption and desorption behaviour of a series of wool powders using radiotracer probes. Wool powders will be prepared using various milling techniques, and their metal-binding properties investigated using radiotracers such as Co, Cu ...

Biomass disks based on fine powder produced from disposed wool fibers were prepared for surface-enhanced Raman scattering (SERS). The wool powders (WPs) were modified by silver nanoprisms via an assembly method and then pressed into disks using a hydraulic laboratory pellet press. Scanning electron microscopy (SEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS) were used t...

Many handmade ancient and recent oriental wool carpets show outstanding brilliance and persistence of colour that is not achieved by common industrial dyeing procedures. Anthropologists have suggested the influence of wool fermentation prior to dyeing as key technique to achieve the high dyeing quality. By means of μ-XRF elemental mapping of mordant metals we corroborate this view and show a de...

The effects of ultrasound on 2,2'-Azinobis(3-ethylbenzothiazoline-6-sulfonate) enzymatic oxidation by laccase (Trametes villosa) has been studied by means of cyclic voltammetry. The reaction was allowed to proceed in the presence of a piece of wool and the coloration depth of the wool fabric was measured by means of K/S. It was observed that cyclic voltammetry is influenced the dyeing process a...

Currently there are no established or proven recycling options for an estimated 100,000 tonnes of wool-rich carpet shred waste produced annually in the UK. The aim of this essay is to review existing knowledge and to identify areas of future research required to identify practicable recycling options. A study of the literature on the possible uses for wool waste identified three main avenues of...

We characterized the perceptual, functional, and structural abnormalities associated with retinal ischemia during a cotton wool spot episode and its sequelae. The border of the visually salient field anomaly mirrored the quantitatively measured relative scotoma. Results of resolution perimetry and high resolution imaging indicated that there was a substantial loss of retinal ganglion cells with...

An in situ arsenic removal method applicable to highly contaminated water is presented. The method is based in the use of steel wool, lemon juice and solar radiation. The method was evaluated using water from the Camarones River, Atacama Desert in northern Chile, in which the arsenic concentration ranges between 1000 and 1300 microg L(-1). Response surface method analysis was used to optimize t...

Wool fibers of different sample conditions were irradiated in different atmospheres by (60)Co gamma-rays and were studied by electron spin resonance method (ESR). It was found that a large percentage of the alpha-carbon radicals of polymer main chain were more long-lived radicals. The ESR measurements of irradiated cortex samples of the wool fibers proved that most radicals from the cortex were...
