Summary: The study demonstrates that activated carbon prepared with longer carbonization time shows superior performance as supercapacitor electrodes, with higher specific capacitance values and better rate capability. These enhancements are likely attributed to its higher specific surface area, more open microporosity, and lower impurity content.

Summary: Agricultural residues are widely available biomass resources that can be used to produce cost-effective activated carbons. The physical characteristics, such as surface area, pore size, and certain surface functionalities, of activated carbon are crucial for its applications in energy storage devices, CO2 reduction reactions, gas adsorption and separation, and water treatment. This review paper discusses the physical properties of activated carbons produced from different biomass sources using various methods. It also explores the effects of activation methods, biomass sources, and other parameters on the surface properties of activated carbon, including specific surface area and pore volume. Additionally, the differences in the characteristics of activated carbon made from different agricultural residues are evaluated, and the potential application of abundant agricultural residues for fabricating electrode materials for supercapacitors is discussed.

Summary: This paper presents a study on the characterization of dielectric properties of samples derived from two different biomass types. The experimental results show that the samples burnt at high temperature exhibit higher dielectric loss when compared to the samples burnt at low temperature, especially for AGA8005h. These results indicate that these samples have excellent electromagnetic energy absorption properties.

Summary: This study found that the application of biochar can increase soil pH, improve the content of soil organic matter and available phosphorus, while reducing the content of ammonium nitrogen and nitrate nitrogen in the soil. Compared to urea-alone application, the addition of biochar can significantly reduce the loss of total nitrogen and nitrate nitrogen, while increasing the retention of fertilizer nitrogen in the soil.

Summary: The production of activated carbon from lignocellulosic biomass using chemical activation is a globally recognized method with scalability, economic viability, and environmental benefits. Chemical activation offers advantages such as energy efficiency, shorter carbonization time, and lower temperature requirements. This study employed potassium hydroxide for chemical activation, resulting in activated carbon with a high specific surface area. The activated carbon derived from rice husk was analyzed using X-ray diffraction, and its potential applications in heavy metal removal, organic pollutant elimination, and hybrid energy storage devices were explored.

Summary: This study analyzed the oxidative stabilization process of wool as a precursor for carbon fibers, revealing that the structure and morphology of the fibers can be preserved below 400℃. The chemical composition of the wool changed with the stabilization temperature, resulting in materials with fibrous morphology and high carbon yield after oxidation at 300℃, suitable for producing carbon fibers.

Summary: Single-phase oxygen stoichiometric LaMnO3 and doped La(0.8)A(0.2)MnO(3) (A = Ca, Sr, Ba) perovskites were prepared by a simple one-step auto-combustion method. Cation-deficient LaMnO3+delta and La(0.8)A(0.2)MnO(3+delta) were obtained by calcination of the former samples in air at 750 degrees C. The catalytic activity of these oxides is influenced by the Mn4+/Mn3+ molar ratio on the surface of the samples and the cation-deficiency of the bulk perovskite structure.
