Summary: Carbon/manganese oxide hybrid materials have attracted extensive attention as lithium-ion battery anode materials due to their abundant resources and simple preparation. However, their poor rate performance, weak cycle stability, and relatively high cost hinder their further development. In this study, a novel carbon/manganese oxide hybrid material was fabricated using low-cost carbonized bamboo leaves and manganese nitrate. The addition of MnSiO3 component in the hybrid material improved its intrinsic conductivity and Li+ diffusion ability, resulting in significantly improved rate capability and cycle performance compared to the hybrid material without MnSiO3. The excellent electrochemical performance of the hybrid material enables its application in lithium-ion full batteries with considerable energy storage performance.

Summary: The study synthesized NDG-Mn3O4 nanocomposite and tested its performance in photodynamic therapy (PDT) and magnetic resonance imaging (MRI) for cancer treatment. The results showed that NDG-Mn3O4 nanocomposite exhibited significant cytotoxicity in cancer cells under laser irradiation and increased generation of singlet oxygen proportional to the duration of laser irradiation. It also showed concentration-dependent enhancement of signal intensity in MRI. These findings suggest the potential application of NDG-Mn3O4 nanocomposites in cancer theranostics.

Summary: The global commercial aviation industry consumed 13.7 EJ of fuel in 2018, with increasing demand expected in the future. Developing Sustainable Aviation Fuels (SAFs) is crucial for mitigating global warming. This study focuses on the properties of cycloalkanes and their potential for reducing aromatic content in aviation fuel. A database of structure-property relationships (SPRs) is developed, considering various physical properties and cycloalkane structures.

Summary: The role of alumina support precursors in Cu-Fe/Al2O3 catalysts for the total oxidation of toluene has been elucidated, with important factors being the structural order of the support precursor, homogeneous distribution of catalytic sites, and metal oxide distribution on the support. Homogeneous distribution of FexOy and CuOx with defined Cu/Fe molar ratio on the Al2O3 support is required for efficient catalytic performance. Introducing low iron concentration during alumina support synthesis procedure leads to a beneficial effect of homogeneous metal oxide distribution on the support.

Summary: This study examined the potential heat storage applications of two different sodalite-type ZIF structures (ZIF-8 and ZIF-90) for adsorption of water, methanol and ethanol, with ZIF-90-water showing the best desorption enthalpy, fastest sorption kinetics and highest potential for heat storage/reallocation applications. This was attributed to ZIF-90's significantly smaller particle size, higher specific surface area, and presence of mesoporosity and polar groups compared to ZIF-8.

Summary: Transition metals as catalysts for total VOC oxidation at low temperatures are challenging. This study prepared and tested iron-modified SBA-15, AlSBA-15, and ZrSBA-15 materials with varying Fe loading for toluene oxidation. The results showed that increasing Fe loading improved the oxidation rate and decreased the temperature required for complete toluene removal. Surface properties of the mesoporous support influenced the type and localization of iron oxide species, and 5 wt. % Fe-containing ZrSBA-15 exhibited excellent activity in the total oxidation of toluene at lower temperatures due to the synergistic effect of Fe-Zr and the presence of accessible and stable Fe2+/Fe3+ active sites.
