Summary: In this paper, a unique hybrid proton exchange membrane (PEM) made of polyvinyl alcohol (PVA) and quaternized polyethyleneimine (QPEI) for direct methanol fuel cells (DMFCs) is presented. The membrane utilizes QPEI as an anchoring agent to enhance compatibility at the organic-inorganic interface and reduce the leakage of phosphotungstic acid (PWA), the proton conductor. The PEM exhibits excellent proton conductivity and methanol permeability properties, making it a promising alternative to Nafion (R) for DMFC applications.

Summary: By incorporating cucurbit[n]urils (CB[n]) into sulfonated poly(ether ether ketone) (SPEEK) matrix, inspired by the proton conduction mechanism of bacteriorhodopsin, hybrid proton exchange membranes (PEMs) with enhanced proton conductivity are fabricated. The CB[n] carbonyl groups serve as proton-conducting sites, while the host-guest interaction between CB[n] and water molecules offers additional proton conducting pathways. The hybrid membranes exhibit significantly improved proton conductivity and superior fuel cell performance.

Summary: Poly(fluorenyl terphenyl piperidinium) (PFTP) with an aromatic backbone was synthesized to produce proton exchange membranes (PEMs) with robust mechanical properties. The introduction of propanesulfonic acid side chains enhanced the phosphoric acid (PA) adsorption capacity and proton conductivity of the resulting sulfonated PFTP (SPFTP-x) membranes. These membranes exhibited good thermal, oxidization, and dimensional stabilities, and the SPFTP-x membranes showed higher PA adsorption capacity and higher proton conductivity than the PFTP membrane. A single cell assembled with SPFTP-50 exhibited a maximum power density of 280 mW cm-2 at 100 degrees C, indicating the promising application of SPFTP-x as a membrane material for high-temperature proton membrane fuel cells.

Summary: Polymer electrolyte membrane fuel cells have gained attention as a promising alternative to petroleum fossil energy due to their low pollution emission, high energy density, portability, and long operation times. However, the performance degradation and high permeability of traditional proton exchange membrane Nafion remain major challenges. This review summarizes the latest achievements in improving the performance of Nafion, particularly for elevated temperature or methanol-fueled systems. Various methods and composite membranes utilizing hydrophilic inorganic material, metal-organic frameworks, nanocomposites, and ionic liquids are discussed. Further revolutionary approaches are needed to accelerate the application of fuel cells and promote the renewal of energy structure.

Summary: In this study, high-performance proton exchange hybrid membranes were established by doping high proton-conducting iHOFs into the Nafion matrix for PEMFC applications. The synergistic effect of iHOFs and Nafion significantly improved the proton conductivity of the composite membranes, leading to enhanced power and current density values in fuel cell performance tests. Adjusting the sulfonic group positions on naphthalene disulfonic acid compounds allowed for the successful synthesis of iHOFs with different types of hydrogen bonds, providing a practical approach for future development in portable power generation.

Summary: This work studied the influence of synthesis conditions on the composition, morphology, water content, and ion-conducting properties of CsxH3-xPW12O40 salts. The morphology of the salts is determined by the concentrations of the reagents during synthesis, with higher concentrations resulting in narrower particle size distribution and larger specific surface area. The composition of the salts depends on both the concentration and ratio of the reagents. The salts contain both adsorption and crystalline water, and proton is assumed to be the main charge carrier for ion transport through the network of adsorption water on the salt surface. The most promising catalyst among the obtained salts exhibits a composition of 1.2+/-0.3 protons, a specific surface area of 136+/-14 m(2)/g, and an ionic conductivity of 0.05 S cm(-1) at room temperature and 75% RH.

Summary: Graphene oxide (GO)-based materials have been extensively studied as low-cost efficient solid electrolytes for fuel-cell application. However, the limited proton conductivity of GO in the out-of-plane directions and associated lower fuel-cell performance restrict their practical application. In this study, a sulfate ion-intercalated three-dimensional graphene oxide (3DSGO) with exceptionally high out-of-plane proton conductivity and improved fuel-cell performance was demonstrated.

Summary: Wedge-shaped dendrons based on benzenesulfonic acid can form different liquid crystal mesophases, such as ordered and disordered columnar hexagonal ones. The size and nature of focal groups as well as the length of aliphatic tails are important factors affecting the phase behavior of these materials. The study found that certain dendrons can form a 2D columnar ordered hexagonal mesophase with three annuli: a central channel, virtually hollow channel, and rigid aromatic part enveloped by an aliphatic matrix. The material shows promise for creating temperature-controlled ion-selective membranes.

Summary: In order to achieve higher efficiencies and reduced pollutant emissions, future vehicle powertrain systems with internal combustion engines need to adopt new advanced technologies. This paper presents a holistic approach by using thermal coatings on the combustion chamber walls to reduce wall heat losses, hydrocarbon, and carbon monoxide emissions. The application of yttria-stabilized zirconia (YSZ) coating allows the wall temperature to follow the gas temperature and perform thermal swing. The results show that the coating can reduce flame quenching distance and total hydrocarbon emission.

Summary: This study demonstrates the reversible formation of hydrogels through hydrophobic interaction using poly(N-alkyl-N-vinylacetamide)s. The polymers with different lengths of alkyl chains can dissolve in ethanol and form thin films. When immersed in water, they swell and form biocompatible hydrogels. The hydrophobic association varies with the length of the alkyl substituents, with shorter chains leading to flowable hydrogels that segregate from excess water and longer chains yielding hydrogels with mechanical properties similar to permanently cross-linked hydrogels.

Summary: This study evaluates the influence of oxygen partial pressure on the discharge performance of potassium-oxygen battery (KOB). It is found that low oxygen partial pressure leads to insufficient oxygen transport and reduced discharge performance, while high oxygen partial pressure improves discharge performance and prevents side reactions. These findings suggest that a high-pressure supply of pure oxygen can further increase the cell performance of KOB.

However, it is difficult to incorporate these techniques with spiral wound modules (SWMs) widely used in water and wastewater treatment. This study developed a prototype membrane system to accommodate angular vibrations with a modified SWM, and experimental results showed that applying angular vibrations can effectively control algal fouling in an SWM with lower energy consumption compared to traditional methods.

Summary: Increasing temperatures worldwide pose a significant health risk, exacerbated by high humidity. Conventional air conditioners contribute heavily to carbon dioxide emissions, with dehumidification being a major factor. Membrane-based dehumidification system offers energy efficiency and non-toxic water vapor removal. This study demonstrates a membrane dehumidification system with polymeric hollow fibers coated with a green polyphenol coating, showing remarkable water vapor transport rate and selectivity. Long-term testing reveals minimal decline in vapor transport and a 4-5 times higher coefficient of performance (COP) compared to conventional dehumidifiers, making it a highly competitive, energy-saving device with reduced emissions and a smaller footprint.
