“…Only in the case of ES‐4h‐AgCl, crystalline peaks of AgCl appeared, as evidenced by the peaks at 2θ values of 27.9°, 32.4°, and 46.4° that correspond to the (011), (200), and (220) planes, respectively. [ 56 ] Nevertheless, the intensity of the peaks corresponding to AgCl was significantly lesser than PCL, which indicated that only a small portion of the halide was deposited in its crystalline form. In the case of CG, several peaks appeared in the diffraction pattern, among which the strongest peak, characteristic of crystalline cellulose, [ 57 ] corresponding to the (200) plane, was observed at 2θ = 22.82°.…”

The rapid emergence of antimicrobial resistance warrants an antibiotic‐free approach to counter the bacterial threat in all possible applications of environmental and biomedical domains. In the context of smart wound dressing, besides imparting anti‐infective characteristics in a nonconventional fashion, it is also essential to imbibe multifunctional attributes like excessive biofluid drainage, easy‐to‐peel, optimal gas permeation, etc., for which appropriate material design is a prime requisite. In this work, poly(ε‐caprolactone) (PCL)− an FDA approved biocompatible polyester− is chosen for imparting antimicrobial properties by surface derivatization with molecularly‐dispersed ionic silver over quaternary ammonium moieties through a facile room temperate and organic solvent‐free approach. To render the other characteristics mentioned above, two different systems comprising PCL with varying porosity, namely, electrospun fibers and polyester‐coated cotton gauze, are developed. The dressing materials are thoroughly characterized and assessed for their structural, surface chemical, morphological, wettability, antibacterial, and peel strength properties as a function of surface derivatization steps. The bactericidal performance of the quaternary ammonium‐functionalized surfaces has enhanced manifold (≈7–10) after derivatizing with ionic silver. The in vivo efficacy study employing the dressing materials reveals ionic silver derivatized electrospun fibers as the most promising candidate, followed by cotton gauze‐coated with 5% PCL.

In this work, we have developed a facile, dry, and environmentally friendly mechanochemical method for the synthesis of cadmium sulfide (m-CdS) nanoparticles in a planetary ball mill using non-toxic precursors. Thiourea was for the first time used as a precursor of sulfide ion in room temperature solid state ball milling synthesis. For comparison of the mechanochemical approach with others, cadmium sulfide nanoparticles were also prepared using the solvothermal method (s-CdS). The crystal structure of cadmium sulfide nanoparticles was studied by XRD, the qualitative chemical band properties were examined by Raman scattering and x-ray photoelectron spectroscopy analysis, and particle morphology and microstructure were investigated by scanning electron microscopy and transmission electron microscopy methods. The sizes of the m-CdS nanoparticles had 5–6 nm in diameter, which is 10 times smaller than the diameter of s-CdS nanorods. The photocatalytic activities of as-prepared cadmium sulfide nanoparticles on the dye degradation and hydrogen production by water splitting were evaluated and the antibacterial activities were also tested. The photocatalytic activity of m-CdS was superior to that of s-CdS in the degradation of Orange II under visible light irradiation. Better results for m-CdS were also evidenced in photocatalytic experiments on hydrogen generation. The maximum rate of hydrogen evolution for m-CdS was 191.9 µmolg−1h−1 at the 120th min,while this indicator for s-CdS was only 58.0 µmolg−1h−1 at the same irradiation time.The better effect of m-CdS was evidenced also in an antibacterial study (namely against gram-positive bacteria).

“…Most of the paper used single solvent like EG, DMSO, or DMF as solvent for the electrocatalyst synthesis in their study. [22][23][24] It is very difficult to compare the effects of solvents in electrocatalysts synthesis by comparing the performance of electrocatalyst reported in various reported published literature as the synthesis method, metal types or electrocatalysts supports always differ from each other in the reported research works. Thus, undoubtedly, this present research work will enable us to understand the effect of various solvents on bimetallic Pt-Co cathode electrocatalyst synthesis for the same catalyst support and metal composition with the same concentration in all the three synthesized electrocatalysts.…”

Highly efficient and low-cost Pt-Co/C AB bimetallic cathode electrocatalysts were synthesized for hydrogen-based proton exchange membrane fuel cell (PEMFC) using three different types of solvent, namely, dimethyl sulphoxide (DMSO), dimethylformamide (DMF), and ethylene glycol (EG). The physical characterization of synthesized cathode electrocatalysts Pt-Co/C AB -DMSO, Pt-Co/C AB -DMF and Pt-Co/C AB -EG was performed by scanning electron microscope-energy-dispersive X-ray (SEM-EDX), X-ray diffraction (XRD), and transmission electron microscopy (TEM) techniques, whereas the electrochemical investigation of all three Pt-Co/C AB electrocatalysts was performed by CV and EIS studies. The synthesized Pt-Co/C-EG electrocatalyst produced the highest power density of 19.61 mW/cm 2 at a room temperature of 33 C. The power density increased to 26.11 mW/cm 2 , that is, 133%, when the cell operating temperature was raised from 33 to 70 C. The excellent performance of the Pt-Co/C AB -EG cathode electrode proves that it can be recommended as a commercial electrocatalyst for PEMFC cathode. In addition, the EG/EG was identified as the best solvent for the synthesis of Pt-Co/C AB cathode electrocatalysts.
