Abstract The scalable production of high-quality copper oxide (CuO) thin films remains challenging for semiconductor and gas sensor applications. This study presents an optimized aerosol droplet method (AMD) that enhances film uniformity and crystallinity through improved substrate positioning and aerosol dynamics. External Source …. Read More
ABSTRACT: This work presents the in-situ synthesis of zinc oxide (ZnO) nanoparticles in an oxidized polyvinyl alcohol (OPVA) matrix, which greatly enhances the final nanocomposites optical, mechanical, and proton conductive properties. Zinc acetate was used as a precursor to synthesis ZnO nanoparticles at different concentrations (1 wt %, 5 wt%, and 10 wt%) within the […]
Sulfonated poly (ether ether ketone) (SPEEK) has received substantial attention for its potential to improve the electrochemical behavior and thermomechanical capabilities of direct methanol fuel cells. This study examines how the integration by solution casting of microcrystalline cellulose (MCC) and 2,3-dialdehyde cellulose (DAC) onto highly sulfonated PEEK (with a sulfonation degree of 80%) affects its […]
OS (olive stones) are a type of lingo-cellulosic biomass that is generated as a by-product in the olive oil industry. In this investigation, the EC (extracted cellulose) from the olive stones was modified with CTAB (cetyl trimethyl ammonium bromide) as cationic surfactant. The obtained MEC (modified extracted cellulose) was used as adsorbent to remove MO […]
This study investigated the potential enhancement of proton conductivity in Nafion membranes through the incorporation of sulfo ethyl cellulose (SEC) at varying weight ratios (5 and 10 wt.%). Results indicated that increasing the weight ratio of SEC led to improvements in water absorption, activation energy, and proton conductivity within the composite membranes. Specifically,the composite membrane […]
Brand hate is a complex feeling that is not easy for companies to recognize. Mednini and Turki (2022) have confirmed that hate can originate from genuine brand haters or an employee who works with competitors, to spread negative word-of-mouth in communities. That is why it is important to detect this emotion. This study aims to […]
An innovative methodology was employed to fabricate ion exchange membranes tailored for fuel cell applications. Thisapproach entailed blending low sulfonated polyether sulfone octyl sulfonamide (LSPSO) with Hectorite (Hect) clay atvarying weight percentages (1 wt%, 3 wt%, and 6 wt%). The resultant composite membranes underwent comprehensivecharacterization via Fourier transform infrared spectroscopy, X-ray difraction, scanning electron microscopy, […]
Composite membranes comprising sulfonated poly (ether ether ketone) (SPEEK) blended with varying proportions of sulfo ethyl cellulose (SEC) at 5 wt% and 10 wt% were fabricated for fuel cell application. The structural, morphological, andthermal properties of these membranes were investigated using Fourier transform infrared spectroscopy, X-ray difraction, scanning electron microscopy, and thermogravimetric analysis. The composite […]
Low-sulfonation-level polyether sulfone octyl sulfonamide (LSPSO) was blended with a layered double hydroxides (LDHs, Mg2AlCl)/sepiolite nanostructure clay as a fller to create an electrolyte membrane for fuel cell applications. Comprehensive characterization of the composite membranes was conducted, encompassing Fourier-transform infrared spectroscopy, X-ray difraction, mechanical stability assessment, thermal gravimetric analysis, ion exchange capability, swelling characteristics, water […]
An interesting approach was employed to fabricate ion exchange membranes tailored for proton exchange membrane applications. This involved blending low sulfonated polyether sulfone octyl sulfonamide (LSPSO) with Layered Double Hydroxides (LDHs) clay at varying weight ratios (1 wt%, 3 wt%, and 6 wt%). Comprehensive characterization of the resulting composite membranes was conducted using diverse techniques, […]
