“…It can be seen from enlarged SEM image (Fig. 5b) that the micron particles have porous structures which can easily adsorb other substances in surroundings [29, 46]. Very recently, TEM characterization of ultrathin sections of wool powder prepared by an ultramicrotomy technique also demonstrated porous feature of wool powder [33].…”

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 to characterize the WPs and disks before and after treatment with silver nanoparticles (AgNPs). The WPs retained porous structures after treatment with AgNPs. The silver nanoprisms on WPs were observed clearly and the localized surface plasmon resonance (LSPR) properties of silver nanoprisms led to blue color of wool powder (WP). The obtained WP disks with AgNPs were confirmed to enhance greatly the Raman signal of thiram. The SERS disks are low-cost and convenient to use, with high sensitivity. The characteristic SERS bands of 10−8 M thiram can be identified from WP disks containing silver nanoparticles.

“…When pH > pH pzc , NSNDPs carry negative charges because of the abstraction of hydrogen ions from the positively charged ammonium groups. The carboxyl groups present in the adsorbent are thought to be mainly responsible for adsorption of cationic dyes [28].…”

Natural superfine needle down particles were successfully prepared on a self‐made machine and applied to remove hazardous dye Vat Scarlet R from aqueous solution. The adsorbent was characterised by scanning electron microscopy and Fourier transform infrared spectroscopy. The effects of contact time, pH, adsorbent dosage, initial dye concentration, and temperature on dye adsorption on natural superfine needle down particles were discussed. Equilibrium adsorption studies revealed that the Langmuir isotherm model gave the best fit to experimental data, which indicates monolayer adsorption on a homogeneous surface. The monolayer adsorption capacity increased with increasing temperature in the range 298–318 K for Vat Scarlet R adsorption, and the maximum obtained adsorption capacity was 76.823 mg g−1 at 318 K. The present study suggested that natural superfine needle down particles could be used as a good and cheaper adsorbent for dye effluent treatment.

Novel poly(glycidyl methacrylate)-grafted Nafion-phosphoric acid membranes for direct-oxidation methanol fuel cells were prepared with a potassium persulfate chemical initiation system for the first time. The introduced epoxy groups were converted to amine groups through a reaction with ethylenediamine, which consequently doped with phosphoric acid (APO 3 H) groups. The latter significantly contributed to enhancing the ionexchange capacity, mechanical properties, and thermal stability. Factors affecting the modification steps were studied. Changes in the chemical and morphological structure were verified through Fourier transform infrared spectroscopy, TGA, and scanning electron microscopy characterization. Various grafting percentages (GP%'s) up to 32.31% were obtained. As a result, the thickness of the grafted membranes increased. Furthermore, the methanol permeability of the modified membranes was reduced with increasing grafted polymer content compared with that of the Nafion membrane. An 83.64% reduction in the methanol permeability was obtained with a polymer grafted content of 18.27%. Finally, the efficiency factor for all of the modified Nafion membranes was enhanced compared with that of Nafion. A fourfold improvement was obtained with membranes with a GP% of 18.27% as a maximum value. Such promising results nominate the used technique as a one for the improvement of Nafion membrane efficiency.
