The stability of different shapes cuprous oxides was tested in deionized water with or without light irradiation. morphology degraded by the formation CuO at surface differently each shape. TiIrO<sub>x</sub>-coated Cu<sub>2</sub>O particles presented improved for overall splitting producing hydrogen and oxygen.
Abstract A series of polypropylene carbonate (PPC)/ZnO nanocomposite films with different ZnO contents were prepared via a solution blending method. The morphological structures, thermal properties, oxygen permeability, water sorption, and antibacterial properties the investigated as function concentration. While all composite less than 5 wt % exhibited good dispersion in PPC matrix, FTIR SEM results revealed that did not lead to strong interaction between unmodified ZnO. As such, poor was...
Abstract The development of flexible displays and electronics is hindered by the disadvantages polymeric window films, such as low mechanical strength, poor optical properties, lack folding rolling reliability. To overcome these critical limitations, a novel colorless polyimide film prepared in this study using concept charge‐transfer complex (CTC) intensification. resulting has tensile modulus 8.4 GPa, total transmittance ≈90%, yellow index below 3, which best recorded balance between...
Relatively high aspect ratio exfoliated graphite (EFG) particles with an average size of 7.4 µm and a nanometer sized thickness 30–50 nm were successfully prepared by thermal treatment at 1050 °C subsequent ultrasonication for application as filler to improve the physical properties eco-friendly poly(propylene carbonate) (PPC). A series carbonate)/exfoliated (PPC/EFG) nanocomposite films different EFG contents via solution blending method. The strongly dependent upon chemical morphological...
Abstract The current paper describes enhanced electrochemical capacitive performance of chemically grown Cobalt hydroxide (Co(OH) 2 ) nanorods (NRs) decorated porous three dimensional graphitic carbon foam /3D GCF) as a supercapacitor electrode. Freestanding 3D GCF is prepared by carbonizing, high internal phase emulsion (HIPE) polymerized styrene and divinylbenzene. PolyHIPE was sulfonated carbonized at temperature up to 850 °C obtain with surface area (389 m g −1 having open voids (14 μm)...
Graphene nanoparticles coated with tannic acid were synthesized as non-halogen flame retardants; further, these electrospun polyurethane to produce multifunctional composite nanofibers. The nanofibers showed improved retardant, antimicrobial, and mechanical properties increasing amounts of bio-based, retardant. For instance, at 5 wt% the peak heat release rate was reduced from 340.75 235.23 W/g along 500% 135% improvement in antimicrobial activity Young's modulus, respectively, compared neat...
Abstract This study evaluated the ecotoxicological effects of sophorolipids (SLs), biosurfactants with potential environmental applications, on aquatic plant Spirodela polyrhiza (duckweed). Key growth indicators, including biomass, foliose thalli, and leaf area, were examined under varying SL concentrations. Results indicated that low to moderate concentrations (below 100 mg/L) had minimal adverse duckweed growth, whereas higher (200–300 significantly inhibited triggered stress responses....
In this work, Al–Si was synthesized via a sol–gel process and introduced in poly 2,2′‐ m ‐(phenylene)‐5,5′‐bibenzimidazole (PBI). As result, series of five Al–Si/PBI composite (ASPBI) membranes (0, 3, 6, 9, 12 wt%) were developed characterized for application high temperature polymer electrolyte membrane fuel cells (HT‐PEMFCs). The chemical morphological structure ASPBI analyzed by Fourier transform infrared spectroscopy, X‐ray diffractometer, scanning electron microscopy. According to the...
