Summary: Fuel cells are eco-friendly appliances that convert chemical energy into electricity efficiently. The proton exchange membrane, such as NAFION, plays a crucial role in these devices. However, due to the limitations of NAFION, researchers are now focusing on developing new generation membranes based on natural materials like cellulose. Therefore, a review of recent studies on using cellulose as a material for proton exchange membranes in fuel cells would be highly appreciated by the scientific community.

Summary: By changing the preparation and pretreatment conditions, the properties of Nafion membranes can be optimized. In this study, a Nafion-NMP membrane with higher conductivity and comparable hydrogen permeability was obtained by casting from a Nafion dispersion in N-methyl-2-pyrrolidone. The increase in conductivity is attributed to the optimization of the Nafion-NMP microstructure, which improves the connectivity of the pores and channels system. This leads to an increased capacity of the membrane electrode assembly compared to a commercial Nafion (R) 212 membrane.

Summary: In the 21st century, proton exchange membrane fuel cells (PEMFCs) are a promising source of power generation due to their high efficiency and eco-friendly design. However, the critical component of PEMFCs, proton exchange membranes (PEMs), have drawbacks such as high cost and reduction in proton conductivity at high temperatures. Recent research has focused on modifying PEMs through composite materials to improve their stability and proton conductivity. This article discusses the current developments in membranes for PEMFCs, with emphasis on hybrid membranes based on Nafion, PBI, and other nonfluorinated proton conducting membranes.

Summary: An asymmetric alumina microfiltration membrane with high performance was prepared by combining freeze and tape casting techniques followed by two sintering steps. The morphology influences were investigated for different solid loadings, additives content and the assembled layer membrane structures. The assembled ceramic membrane had an average pore size between 30 and 50 m, suitable for microfiltration separation with porosity in the range of 26-50% and water flux of 11-32 m(3) m(-2) h(-1) bar(-1).

Summary: We conducted a comprehensive investigation on the high-frequency dielectric properties of (ZrO2)100-x(BaTiO3)x heterostructures. By adjusting the content of BaTiO3, we could modify the dielectric constant of the resulting ceramic sheets. Our results demonstrated successful fabrication of heterostructured ceramic sheets and the ability to tailor the electric, structural, and dielectric properties of both ZrO2 and BaTiO3 materials. Furthermore, the evolution of the dielectric constant could be manipulated according to specific technological applications.

Summary: By integrating crystallographic texture and second-phase toughening strategies, the fracture resistance and mechanical reliability of alumina multilayer composites have been effectively improved. The addition of ZrO2 significantly enhances the mechanical performance of the composites and reduces sensitivity to flaw size. The enhanced mechanical properties are mainly attributed to higher compressive stresses, more crack bifurcations, and longer crack deflection paths within the textured layers.

Summary: This study thoroughly investigates the impact of MnO2 as a co-dopant on the sinterability, thermal expansion, crystal structure, and ionic conductivity of ScSZ electrolytes. The results show that the addition of 2 mol% MnO2 significantly enhances the oxide ion conductivity, lowers the peak sintering temperature, and stabilizes the cubic structure. It is also found that manganese predominantly enters the structure as Mn2+ and higher valence states are present at the surface and grain boundaries.

Summary: Composite modulation in the superparaelectric state of the BTBZ-CT system is proposed as an effective strategy to achieve both NTCC and excellent energy storage performance in dielectric ceramics. The addition of BZ and CT to BT ferroelectrics can move the SPE state to the normal use temperature zone, resulting in enhanced NTCC characteristics and energy storage performance. Furthermore, intentional precipitation of CT at grain boundaries can refine the grain size, increase the bandgap, and strengthen the local electric field distribution, thereby enhancing the breakdown electric field.

Summary: This study analyzes the influence of calcia refractory purity on the properties of calcia crucibles. Higher purity calcia results in well-developed grains and improved hydration resistance, leading to better high-temperature strength and thermal shock resistance. In contrast, lower purity calcia crucibles exhibit inferior properties. Therefore, high-purity calcia is considered a potential refractory for manufacturing oxide crucibles.

Summary: To raise the operating temperature of Si-based ceramic matrix composites (CMCs), researchers have applied thermal/environmental barrier coating (T/EBCs) materials, typically rare earth silicates. However, the high thermal conductivity and the mismatch of thermal expansion have been major challenges in developing new materials that can offer thermal insulation and environmental protection to CMCs. In this study, entropy engineering was used to create a multicomponent equi-atomic single-phase pyro silicate with extremely low thermal conductivity and enhanced water vapor corrosion resistance. The research findings show the potential of high entropy disilicates in achieving ultra-low thermal conductivity and low weight loss in corrosive environments.

Summary: This study provides an atomic-scale description of the high-velocity impact of alpha-Al2O3 particles onto an alpha-Al2O3 substrate during Aerosol Deposition (AD). The results suggest that the crystal orientation plays a crucial role in both plasticity and damage of the nanoparticles. Impact velocity has a direct correlation with plasticity and fragmentation, but adhesion efficiency has only a marginal increase. The crucial element lies in the substrate's surface alterations caused by the fragments left on the substrate after impact.

Summary: This study characterized the long-term and repeated ablation properties of modified Cf/HfC-SiC composites with YB4-Al2O3-Si3N4 under an air plasma torch. The structural stability and viscosity of the oxide layer were found to affect the ablation resistance of the composites. By forming nano c-HfO2 grains and high-viscosity Al-Si-Y-O glassy phase, the structural stability of the oxide layer was improved, resulting in enhanced ablation resistance. However, the oxidation of Si3N4 led to the formation of NO, NO2, and excessive SiO2 glassy phase, which resulted in a porous structure and reduced the viscosity of the oxide layer. Therefore, the addition of Si3N4 decreased the ablation resistance of the composites.

Summary: In this study, solid solutions of xBi(Ni1/2Hf1/2)O-3-(1 - x)PbTiO3 (xBNH-PT) were synthesized to investigate their phase boundary behaviors and physical properties. The presence of a tetragonal-pseudocubic phase boundary and a spontaneous ferroelectric-relaxor transition at specific compositions were confirmed. The introduction of a tetragonal-pseudocubic phase boundary improved the piezoelectric properties and suppressed the spontaneous ferroelectric-relaxor transition.
