In the present research, a novel kind of homogeneous cation-exchange membranes were provided by solution casting technique via blending of sulfonated polyvinylchloride (SPVC) and sulfonated poly phenylene oxide (SPPO). The performance of the membranes was evaluated by membrane potential, areal resistance, transport number, ionic permeability, ion-exchange capacity, fixed ion concentration, energy consumption (EC), current efficiency, mechanical properties, membrane oxidative stability, water contact angle and water content tests. The microstructures of the membranes were investigated by scanning electron microscopy. Membrane with 70:30 (w/w) composition (SPPO: SPVC) exhibited suitable efficiency, mechanical strength and oxidative stability in comparison with other samples in this study. Also, amino groups have been successfully attached to the multi-walled carbon nanotubes (MWCNTs) structure and the modified MWCNTs were selected as filler additive. The results revealed that a series of membranes with improved transport properties, hydrophilicity and EC can be prepared with the polymeric matrix-containing aminated-MWCNTs.

Semi-rigid bases are widely used in road construction due to their excellent properties, high rigidity, and frost resistance, and they have been in service for many years. However, as the service life increases, the maintenance demands also grow, with traditional maintenance methods still being the primary approach. Based on a typical case using ground-penetrating radar (GPR) technology, this study explores the issue of cracks in semi-rigid bases and their impact on overlay layers.

The introduction of biological therapies has revolutionized inflammatory bowel disease (IBD) management. A critical consideration in developing these therapies is ensuring adequate drug concentrations at the site of action. While blood-based biomarkers have shown limited utility in optimizing treatment (except for TNF-alpha inhibitors and thiopurines), tissue drug concentrations may offer valuable insights.

Hydrogen, as a zero-emission fuel, produces only water when used in fuel cells, making it a vital contributor to reducing greenhouse gas emissions across industries like transportation, energy, and manufacturing. Efficient hydrogen storage requires lightweight, high-strength vessels capable of withstanding high pressures to ensure the safe and reliable delivery of clean energy for various applications. Type V composite pressure vessels (CPVs) have emerged as a preferred solution due to their superior properties, thus this study aims to predict the performance of a Type V CPV by developing its numerical model and calculating numerical burst pressure (NBP).

Natural plant fibers (NPFs) have emerged as a sustainable alternative in the manufacture of composites due to their renewability and low environmental impact. This has led to a significant increase in the use of natural plant fiber-reinforced polymers (NPFRPs) in a variety of industries. The diversity of NPF types brings a wide range of properties and functionalities to NPFRPs, which in turn highlights the urgent need to improve the properties of fiber materials in order to enhance their performance and suitability.

Si anode materials are promising candidates for next-generation Li-ion batteries (LIBs) because of their high capacities. However, expansion and low conductivity result in rapid performance degradation. Herein, we present a facile one-pot method for pyrolyzing polystyrene sulfonate (PSS) polymers at low temperatures (≤400 °C) to form a thin carbonaceous layer on the silicon surface.
