Summary: The measurement of kinetic parameters in the pyrolysis of polyolefins requires the use of a lumped kinetic model. A non-isothermal method was established to predict the product distribution, and the measured parameters were validated using isothermal experimental data. The non-isothermal method proves to be a faster approach for measuring intrinsic rate constants at high temperatures.

Summary: The adsorption of aqueous ferulic acid (FA) solution on protonic zeolites was investigated. Three types of zeolites and various adsorption parameters were analyzed and optimized. The HY zeolite with a SiO2/Al2O3 ratio of 12 exhibited a high adsorption percentage of 90% at 30°C, 5 minutes, 10 g L-1, and pH <= 3. UV-Vis DRS and FTIR spectroscopies revealed the structures of the adsorption complexes formed by the interaction between the FA molecule and the zeolite surface, involving phenol and carboxyl groups.

Summary: Using fluidic dielectrophoresis, the motion of a polarizable liquid-liquid interface can be used to quantify reaction rate kinetics in solution. By controlling the electric field and frequency, the direction and magnitude of interface displacement can provide information about the binding dynamics. The measurement of the crossover frequency allows for quantitative analysis of the binding kinetics.

Summary: A water-soluble ruthenium(II) complex (L) was used to modify the surface of an indium-tin oxide (ITO) electrode decorated with a nanostructured layer of TiO2 (TiO2/ITO). Singlet oxygen (O-1(2)) produced by the complex under visible light irradiation triggers a cathodic photocurrent when the electrode is illuminated and biased at a proper reduction potential. The L/TiO2/ITO electrode was characterized and demonstrated efficient oxidation of phenolic compounds, with a limit of detection (LOD) of 0.3 mu mol dm(-3).

Summary: In this study, the low-temperature oxidation mechanism of carbon-neutral fuel diethoxymethane (DEM) was investigated. The reaction potential energy surfaces (PESs) of three different DEM radicals reacting with O2 were explored. The rate constants of the relevant reactions were calculated and the main reaction channels were discussed. The data obtained were incorporated into the DEM combustion model, showing good agreement with experimental data and providing support for further study.

Summary: This study establishes a chemical kinetic model describing isoprene pyrolysis and investigates the reaction pathways involved. The findings suggest that isoprene pyrolysis partially explains the formation of aromatic species observed in vegetation fire plumes. The validated kinetic model provides insights into the understanding of isoprene pyrolysis and its related atmospheric pollutants in naturally occurring vegetation fires.

Summary: Understanding the thermal degradation characteristics, kinetic behavior, and thermodynamic parameters is crucial for designing and optimizing large-scale conversion systems. This study compared the pyrolysis characteristics and thermodynamic parameters of corn cobs, peanut shells, and sugarcane bagasse using high heating rates in TGA experiments. The results showed that increasing heating rates affected the pyrolysis characteristics due to compositional differences. The kinetic parameters estimated that the activation energies of corn cobs and peanut shells were lower than that of sugarcane bagasse.

Summary: In this work, a silver-catalyzed and regioselective alkylation of chromones with alkyl carboxylic acids under mild conditions is reported. Various alkyl groups, including tert-butyl, cyclohexyl, and adamantyl, can be successfully introduced at the C2 site of chromones with moderate to good yields. A gram-scale experiment was conducted, and a plausible mechanism was proposed.

Summary: Vanillin and vanillic acid are two lignin pyrolysis products generated by biomass combustion. The gas-phase oxidation mechanisms of vanillin and vanillic acid initiated by OH/NO3 radicals were investigated using density functional theory. The primary reactions involve OH/NO3 addition and H-atom abstraction, leading to the formation of various oxidation products. The total rate constants and atmospheric lifetimes of the oxidation processes were calculated, providing valuable information for further experimental research.
