Summary: The relationship between the chemical compositions of green mesocarbon microbeads (GMCMBs) and the electrochemical behavior of carbonized mesocarbon microbeads (CMCMBs) for lithium-ion batteries was investigated. GMCMBs with different anisotropic contents were prepared from mesophase pitch and carbonized, showing different structural characteristics and electrochemical performances. The study revealed that higher anisotropic content in GMCMBs led to a more ordered structure and higher initial coulombic efficiency, while lower anisotropic content resulted in higher porosity and disorder, leading to higher reversible capacity and superior rate performance.

Summary: The study investigated methane hydrate formation process in confinement through high-pressure methane sorption experiments on two wet materials with similar pore size distributions, B-PMO (hydrophobic) and MCM-41 (hydrophilic). The results showed that external water and 'core water' inside the pore were rapidly consumed in the first step to form bulk-like hydrate, while adsorbed water was slowly consumed in the second step to form less stable confined hydrates.

Summary: In this study, biolubricants were synthesized from vegetable oils through esterification reactions using sulfonated mesoporous silica as catalyst. The sulfonic surface group on the catalyst significantly influenced the esterification reaction, and the functionalization of the catalyst led to a decrease in surface area and pore diameter. The sulfonated catalyst exhibited high conversions and selectivities.

Summary: This study investigates the effect of different alumina supports on the dispersion of CuO and the performance of three-way-catalytic converters (TWC). The results show that alumina samples synthesized via soft-templating routes have a large surface area and low crystallinity, which favor the formation of highly dispersed and strongly bonded CuO species. The use of amorphous mesoporous alumina completely prevents the formation of crystalline CuO even at high metal loading. The catalytic evaluation of this material demonstrates an enhanced oxidation activity with increasing metal loading.

Summary: Although landspreading and incineration are currently used for the disposal of primary sludge and biosludge in Uruguayan pulp mill wastewater treatment plants, direct incineration for energy recovery is the most preferred method. This study proposes hydrothermal carbonization (HTC) as a pre-treatment method to enhance the fuel characteristics of the sludge. The results show that HTC affects the sludge differently in terms of carbon fixation, energy densification, and conversion efficiency.

Summary: In this study, we have successfully created a new aryl amino-substituted graphitic carbon nitride (g-C3N4) catalyst with atomically dispersed Mn that is capable of directly generating hydrogen peroxide (H2O2) from seawater. This catalyst showed excellent reactivity, achieving up to 2230 μM H2O2 in 7 hours from alkaline water and up to 1800 μM from seawater under the same conditions. The catalyst can be easily recovered and reused without any significant loss in performance. The generation of H2O2 in this catalyst occurred through a unique two-electron water oxidation reaction process involving both direct and indirect pathways.

Summary: This study presents an innovative approach to improve the photovoltaic conversion characteristics and stability of perovskite solar cells through carbon electrode interface modification. By in-situ polymerization and carbonization on the surface of nano-graphite, a dendritic structure carbon electrode is formed, reducing the work function and aligning the energy levels with perovskite. This leads to improved charge and hole collection efficiency, resulting in increased photovoltaic conversion efficiency. Furthermore, the modified carbon electrode-based perovskite solar cells exhibit exceptional stability, maintaining high efficiency even without encapsulation.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.

Summary: A detailed understanding of the interaction between molecules and two-dimensional materials is crucial for incorporating functional molecular films into next-generation 2D material-organic hybrid devices. This study compares the energy level alignment of different-sized fullerenes on a Moire superstructure and finds that C-84 fullerenes can be either neutral or negatively charged depending on slight variations of the electrostatic potential. This discovery suggests a new path to achieve ambipolar charge transfer without overcoming the electronic gap of fullerenes.
