Summary: This study investigates the chemical effects on surface shaping and planarization in semiconductor wafer polishing using reactive force field molecular dynamics simulations and experimental studies. The inclusion of aqueous hydrogen peroxide generates Si-O-H and C-O-H species, which can be easily removed through mechanical abrasion. The concentration of hydrogen peroxide has a positive impact on material removal. The chemical effects on the Si-face of 6H-SiC crystals are found to be more significant than those on the C-face.

Summary: This study investigated the passivation mechanism of three azole inhibitors on cobalt, with 1-H carboxyl benzotriazole (CBT) showing the strongest passivation effect. Analysis suggested that the carboxyl group on CBT played a crucial role in preventing cobalt oxidation. Furthermore, the presence of methyl on 5-methyl-benzotriazole (TTA) led to better passivation effect compared to benzotriazole (BTA).

Summary: This study investigates the mechanism of soot formation inhibition under electric field during fuel combustion. The computational simulations reveal that the electric field alters the dispersion and stacking of polycyclic aromatic hydrocarbon (PAH) clusters, inhibiting PAH nucleation. The electric field also inhibits dehydrogenation and C-C bond cracking of PAHs, leading to reduced growth of large graphite lamella. The experimental validation using scanning electron microscopy and temperature-programmed oxidation confirms the inhibitory effect of electric field on soot formation.

Summary: Microwave-assisted catalytic pyrolysis of waste plastics has great potential for hydrogen generation. Molecular dynamics (MD) simulation using the ReaxFF method was conducted to study the mechanism of Fe catalyzed pyrolysis of plastics under microwave heating. The results show that microwave enhances Fe cluster adsorption capacity, reduces the dissociation energy of C-H bonds, and promotes the cleavage of C-C bonds through H radicals at low temperature. These findings provide a theoretical basis for valorising waste plastics aided by microwave and demonstrate the reliability of ReaxFF MD.

Summary: In this study, the electric field was used to modify the pyrolysis rate of n-alkane fuels. The pyrolysis process and mechanism of three n-alkanes (n-pentane, n-heptane, and n-decane) under the electric field were investigated. It was found that the electric field strength had an impact on the pyrolysis rate, with weak electric fields promoting pyrolysis and strong electric fields inhibiting pyrolysis. The electric field also induced molecular polarization and deformation, resulting in lower energy barriers for carbon bond and hydrogen bond dissociation. The increased intermolecular distance and reduced interaction energy caused a decrease in collision frequency. The contribution of the electric field to both individual molecule decomposition and inhibition of molecular motion played a role in the overall pyrolysis of n-alkanes. This work provides theoretical support for promoting fuel utilization using electric energy.

Summary: The bias-induced oxidation was investigated using ReaxFF molecular dynamics simulations to fill the knowledge gaps in understanding physical-chemical reactions at the atomic scale. This understanding is crucial for accurate process control of bias-induced local anodic oxidation nano lithography. The simulation results showed that bias-induced oxidation mainly led to the formation of Si-O-Si bonds in the oxide film and the consumption of H2O, while the chemical composition on the oxidized surface remained essentially unchanged.

Summary: This study investigates the effect of surface roughness on the interface bonding performance (IBP) during the hot-compression bonding process. It is found that a smaller surface roughness leads to a weaker degree of rotational dynamic recrystallization at the interface, and the interface bonding mechanism is completely transformed into discontinuous dynamic recrystallization. Additionally, a decrease in roughness reduces the number of interface pits due to the weakening of oxide scale aggregation and abrasive inclusion mechanism. However, the elongation of the tensile specimen does not significantly increase when the roughness is lower than 0.698 μm Sa.

Summary: The quasi-static mechanical behavior and strengthening mechanism of AISI 316H stainless steel at cryogenic temperatures were investigated in this study. It was found that the yield strength and tensile strength of 316H significantly increased while the elongation decreased with decreasing temperatures. Martensitic transformation was observed as the main cryogenic temperature strengthening mechanism below -120 degrees C. The flow stress increased with decreasing temperature and increasing strain rate during the Split-Hopkinson pressure bar (SHPB) test. The sensitivity factors of strain rate and temperature were negatively correlated with temperature, and cryogenic temperature had a significant strengthening effect. A modified Johnson-Cook constitutive model, considering the effect of cryogenic temperatures, was established to describe the mechanical properties of 316H over a wide range of temperatures and strain rates.

Summary: In this study, the dynamic mechanical properties of SA508-3 steel were investigated using split Hopkinson pressure bar tests. The results showed that the dynamic stress-strain response of SA508-3 steel is influenced by both strain rate and temperature, with temperature sensitivity being independent of the strain rate. A constitutive model based on the Johnson-Cook model was built to describe the dynamical property of SA508-3 steel, and it accurately predicted the flow stresses at different strain rates and temperatures. The established model was also successfully applied in a finite element analysis of the milling process of SA508-3 steel, with the predicted cutting forces matching well with the experimental results.

Summary: In this study, the effect of residual stress-related on the deformation of pure copper substrate during double-sided lapping was investigated using finite element method (FEM). A prediction model was proposed to simulate workpiece machining deformation in the lapping process by considering the initial residual stress and the stress caused by lapping. The results showed that the warping deformation of the workpiece in double-sided lapping is primarily caused by the redistribution of initial residual stress due to uneven material removal.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
