Summary: In this study, the catalytic pyrolysis of D-glucose was conducted using a thermogravimetric analyzer and formulated red mud as the catalyst. The kinetic parameters of DG decomposition in the presence of the catalyst were determined. The red mud catalyst reduced the overall activation energy of DG conversion compared to sand and altered the reaction mechanism.

Summary: The low-temperature electrosynthesis of titanium suboxide was carried out on mild steel, with a bilayer coating of TinO2n-1 and poly(N-methyl pyrrole) to improve corrosion resistance and achieve a homogeneously dispersed titanium oxide phase with various oxygen contents. The corrosion performances of the coatings were significantly improved by the bilayer structure, providing better protective properties and reducing porosity.

Summary: The electrocatalytic effect of Sb3+, Bi3+, Cu2+, and Sn2+ ions for the V3+/V2+ redox reaction on graphite electrode is investigated, and their binary, ternary, and quaternary ions are studied for the first time. Metal ions are reduced and electrodeposited in situ during the redox reaction, resulting in the homogeneous distribution of metal nanoparticles on the electrode surface. The study suggests potential application in vanadium redox flow batteries.

Summary: Gasification kinetics of six chars from residual origin were studied under relatively low temperature, low CO2, and high H2O partial pressures. The Random Pore Model (RPM) showed the best fit to experimental results, but the selection of the reaction model depended on the ash composition, specifically the presence of alkali and alkaline earth metals. Chars with ash content higher than 30% wt. were modeled with the RPM model, while chars with the highest K/Si ratio required modified versions of the RPM to accurately predict reaction rates. Textural properties played a key role in determining reaction parameters, such as the pre-exponential factor and activation energy, for chars with similar ash content and composition.

Summary: This paper studies the thermal stability and decomposition of cork materials with and without silica aerogel filler. The results show that the decomposition is inhibited and the pyrolysis is significantly reduced with the addition of silica aerogel. This finding suggests that silica aerogel-infused cork may be a promising raw material for biofuel production with reduced environmental pollution.
