Summary: In this work, a hierarchical CoO-Co4N@NiFe-LDH/NF electrode, prepared via a three-step hydrothermal-nitridation-electrodeposition pathway, demonstrated low overpotential values and favorable reaction kinetics for both HER and OER. The assembled alkaline electrolyzer using this electrode as both anode and cathode showed efficient performance with low voltage and stability. Additionally, a urine-mediated electrolysis cell exhibited efficient catalytic activity, lowering the voltage required for water splitting compared to a urea-free electrolysis cell.

Summary: The hard-template method was used to prepare hierarchical porous carbon materials with high gravimetric and volumetric capacitance using Al-Cu double hydroxides as templates. The Al/Cu molar ratio was found to significantly affect the morphology and composition of the templates, resulting in hierarchical porous architecture in the fabricated carbon materials. The HPCs showed excellent capacitance performance as electrode materials for supercapacitors, demonstrating high energy density and capacitance retention in Na2SO4 electrolyte.

Summary: Three new copper organodiphosphonate compounds have been synthesized hydrothermally, with different organic amines templating the formation of one-dimensional ladder and two-dimensional layer structures. The coordination behavior of the diphosphonate ligand and the organic amines play a crucial role in isolating different dimensionality among the hybrid structures.

Summary: The main goal of this study is to evaluate different approaches for predicting and evaluating the bonding strength of glued laminated timber manufactured using walnut wood layers and a natural adhesive, with the aim of reducing formaldehyde emissions. The study found that response surface methodology provides better predictive performance with lower levels of errors compared to adaptive neuro-fuzzy inference network and artificial neural network. Additionally, the other two methods support the response surface methodology approach for accurate evaluation and optimal production point determination in laminated product fabrication.

Summary: We synthesized ZnO nanoparticles and hierarchical nanorod structures using four different alcohols, and the synthesis reactions were controlled by the type of alcohol used. Absolute alcohol allowed for better control and smaller nanoparticles of 5 nm were obtained. The nanorod growth was influenced by the seed layer and the resulting nanorods exhibited persistent photoconductivity under UV irradiation. The physical, chemical, electrical, and optical properties of the ZnO nanostructures were optimized using alcoholic solvents.

Summary: The study focuses on the fabrication and characterization of bimetallic hierarchical structures (BHSs) using hot-working tool steel RMD535 and martensitic stainless steel RMD650. The microstructure evolution, interfacial properties, and mechanical properties were investigated. The results showed that different diffusion behaviors occurred at the interface between RMD650-535 and RMD535-650 due to various factors. The BHSs with 75% hard material and 25% soft material exhibited the highest yield strength and a slightly decreased elongation. The strain distribution in BHSs led to extra strengthening and delayed strain/stress localization.

Summary: In this study, MnCo2S4 nanosheet catalyst was successfully synthesized and found to exhibit superior performance in hydrogen evolution. Compared to MnCo2S4, MnCo2S4 showed low overpotentials, moderate Tafel slope, and excellent sustainability. The outstanding performance can be attributed to the increased number of electrochemically active sites and enhanced electronic conductivity on the catalyst surface.

Summary: Networks are important for describing relationships between people, roads between cities, reactions between chemicals, and other interactions. Bipartiteness, dividing the network into two groups, can facilitate the study of the network's structure. We have developed an algorithm that can find a near-optimal bipartisation within a reasonable time frame and used it to uncover the hidden structure of the CSD cocrystal network.
