Performance of high sulfonated poly(ether ether ketone) improved with microcrystalline cellulose and 2,3-dialdehyde cellulose for proton exchange membranes

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 […]

Methyl Orange Adsorption onto Modified Extracted Cellulose from Olive Stones: Kinetics, Isotherms, Thermodynamic, Mechanism Studies, and Desorption

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 […]

Sulfo ethyl cellulose/Nafion composite forhigh-temperature proton exchange membrane

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 […]

Natural Language Processing for Detecting Brand Hate Speech

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 […]

Signifcant augmentation of proton conductivity in lowsulfonated polyether sulfone octyl sulfonamide membranesthrough the incorporation of hectorite clay

Graphene - Laser-induced porous graphene electrodes from polyketimine membranes for paracetamol sensing - Become

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, […]

Incorporating of sulfo ethyl cellulose to augment the performanceof sulfonated poly (ether ether ketone) composite for protonexchange membrane fuel cells

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 […]

Physicochemical characterization of chitin extracted by different treatment sequences from an edible insect

Chitin present in the shell of edible insects is a potential source of chitin, lipids, and proteins, and it exerts various biological activities. Thus far, only a few studies have focused on the use of chitin as a source of high-protein-diet oligosaccharides. The use of insect chitin for the production of high-protein-diet oligosaccharides can lessen […]
