Summary: This study focuses on the hydrogen storage ability of sol-gel synthesized Ce2Y2O7 nanoribbons as active materials. The impact of different carbonous materials (such as graphene oxide, nitrogen-doped graphene quantum dots, and g-C3N4) on the hydrogen storage capacity of Ce2Y2O7 nanoribbons was compared. The carbonous nanocomposites provided were characterized using various methods to identify their phase purity, shape, and porosity. Galvanostatic charge-discharge profiles were performed for all samples to achieve optimal capacitance. The results showed that the nanocomposites of GO/Ce2Y2O7, N-GQDs/Ce2Y2O7, and g-C3N4/Ce2Y2O7 had maximum discharge capacities of 656, 686, and 757 mAhg(-1), respectively, while pristine Ce2Y2O7 nanoribbons had a discharge capacity of 643 mAhg(-1) after 15 cycles.

Summary: With increased development and electricity generation, it is crucial to consider energy storage systems to overcome the discontinuity in renewable production. Hydrogen is an ideal energy carrier for future mobility, such as automotive applications. However, current hydrogen storage materials do not meet all requirements in terms of storage capacity and commercialization. Developing new materials with large surface area, homogeneous texture, active-conductive profiles, large oxygen vacancies, and low cost is crucial. Multiphase materials composed of these materials can meet the requirements in this field.

Summary: This study presents a gel polymer electrolyte (GPE) interlayer to stabilize the Li|LAGP interface and address the challenges caused by side reactions and poor thermal stability. The GPE, composed of a solvate ionic liquid and a hyperbranched polyanionic copolymer, ensures excellent compatibility and protection between LAGP and Li metal anode. Additionally, the introduction of a solvate ionic liquid with non-inflammability effectively avoids thermal runaway between lithium metal and LAGP at high temperatures.

Nanostructured Ce2Y2O7 with five different morphologies was synthesized using a sol-gel process assisted by trimessic acid. Charge-discharge chronopotentiometry tests were conducted under the same conditions to compare the effects of Ce2Y2O7 nanostructures on hydrogen storage capacity in KOH electrolyte at a current of 1 mA. The results show that the highest capacity is observed in very thin nanoribbons (643 mAhg(-1)), while the lowest capacity is found in agglomerated ribbons assembled with particles (276 mAhg(-1)).

Summary: In various industries, it is crucial to understand the relationship between transfer properties like viscosity and thermal conductivity coefficients for design and engineering purposes when processing non-Newtonian fluids, especially viscoelastic fluids. However, most studies on nanofluids have been limited to inadequately considering only three components of viscoelastic fluids. In this research, multiwalled carbon nanotubes were chemically modified to obtain nanoparticles, which were then used to prepare viscoelastic-based nanoliquids (VNLs). The stability, thermal conductivity, and viscosity of the VNLs were examined. The findings provided insights into the behavior and properties of these complex fluids.
