Summary: The issue of narrow micropores in traditional protonic type Zeolite Socony Mobil-5 (HZSM-5) catalysts, which restrict the diffusion of large-molecular reactants/products, was tackled by preparing hollow HZSM-5 with a mesoporous shell. The efficient catalyst of Hollow(30)-TP showed significantly higher aromatic hydrocarbon yields for cellulose and hemicellulose compared to traditional HZSM-5, and exhibited excellent reusability and regeneration due to increased accessibility to acid sites.

Summary: Rice husk and polystyrene wastes were successfully converted into value-added products using microwave-assisted catalytic co-pyrolysis. The addition of rice husk increased the yield of char and gases, while the addition of polystyrene increased the yield of oil. Co-pyrolysis showed a synergistic effect on the yield of gases, and significantly reduced energy consumption compared to pyrolysis. The obtained products consisted of carbon-rich char, oil rich in monoaromatics, and gases consisting of CO, H-2, and CH4.

Summary: The relay catalytic upgrading of coal pyrolysis volatiles using different combinations of CaO and HZSM-5 zeolite catalysts improves tar quality and reduces catalyst deactivation. The CaO-HZSM-5 layout demonstrates the best performance compared to other layouts. CaO promotes cracking of large molecules in tar, while HZSM-5 zeolite helps generate more aromatics. This base-acid relay catalytic upgrading strategy shows promise in enhancing tar quality and prolonging catalyst lifespan during coal pyrolysis.

Summary: In this study, the characteristics of rice husk and biochar were improved through microwave-assisted phosphoric acid pretreatment (MAPP) of rice husk and co-pyrolysis with low-density polyethylene (LDPE). The pretreated rice husk showed enhanced properties, including higher fixed carbon and volatile matter, lower ash content, and improved thermal stability. The biochar produced through the combined mode exhibited higher carbon content, lower ash content, lower H/C and O/C values, and a higher Brunauer Emmett and Teller (BET) surface area compared to biochar produced from rice husk alone. Raman spectroscopy and XRD results confirmed the more orderly structure and fewer structural defects in the biochar.

Summary: The study investigated the kinetics of ethylene oligomerization over Ni-H-Beta catalyst at temperatures between 50 and 100 degrees C and pressures between 5 and 28 atm. The reactions showed different apparent activation energies for butene, hexene, and octene formation, with evidence suggesting that octene formation mainly proceeds via the cascade co-oligomerization of re-adsorbed butene with ethylene.

Summary: This study investigates the adsorption of ethylene on Ni-H-Beta particles to understand the roles of nickel and Bronsted sites in the catalytic oligomerization of ethylene. The results suggest the participation of two active sites in the formation of Cossee-Arlman centers and the dissociation of ethylene upon adsorption. Further characterization reveals the presence of highly dispersed Ni2+ on the catalyst surface and the interaction with lattice oxygen and free NiO crystals. The presence of residual Ni2+ and Bronsted sites hinders the formation of nickel-hydride sites and the conversion rate of ethylene. The proposed mechanism involves adsorption of ethylene on Ni2+ and a Bronsted site. This research has important implications for improving ethylene oligomerization processes over nickel-based heterogeneous catalysts.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
