Summary: Using DFT-D3 method, the adsorption of 15 types of transition metal clusters on graphene and N-doped graphene was systematically studied. The results show that clusters adsorbed on N-Gr surface have stronger interaction compared to those on Gr surface, while 3d series clusters exhibit similar geometries on both surfaces. The migration of preferred adsorption sites for transition metals is different on Gr and N-Gr surfaces, and the charge transfer is lower on N-Gr surface due to a change in growth mechanism. Additionally, clusters on N-Gr surface disperse more and exhibit a three-dimensional growth mode on Gr.

Summary: This study systematically explores the catalytic activity of tungsten monocarbide (WC) by studying the methane dehydrogenation and C-C coupling processes on WC surfaces using density functional theory (DFT) calculations. The results indicate that the W-terminated WC(0001) surface is the most favorable exposed surface with a lower surface energy. Additionally, the Co(111), Ni(111), and W-terminated WC(0001) surfaces exhibit similar catalytic properties in methane dehydrogenation, and the rate-limiting step on the W-terminated WC(0001) surface is the dissociation of CH*. C-C coupling through CH* intermediates on the W-terminated WC(0001) surface favors the formation of C2H2 kinetically.

Summary: In this study, the interaction between ionic liquids (ILs) and graphene oxide (GO) was investigated using density functional theory. It was found that the adsorption of ILs on GO reduced the HOMO-LUMO energy gap, weakened hydrogen bonding interactions, and charge transfer played a key role in the adsorption process. Additionally, the forces at play depended on whether the ILs were on the hydroxyl side of GO or not, with van der Waals interactions being prominent.

Summary: This study used electronic structure calculations to investigate the adsorption of carbamazepine (CBZ) in eleven all-silica zeolites. It was found that zeolites with one-dimensional channels formed by twelve-membered rings exhibited the highest affinity towards CBZ. The fit of CBZ into the zeolite pores, maximizing dispersion interactions, was identified as the dominant factor determining the interaction strength. The calculations also contributed to the understanding of the atomic-level interaction between functional organic molecules and all-silica zeolites.

Summary: The interaction between organic molecules and MXene surface depends on the type of functional groups, while the strength of the interaction is determined by the type of surface functional groups and the number of hydrogen bonds. MXene saturated with -OH or -F groups can form strong chemical and hydrogen bonds with organic molecules, leading to strong adsorption energy and charge transfer, while MXene saturated with -F or -O groups mainly exhibits physical interactions, with low adsorption energy and minimal charge transfer.

Summary: The cracking reaction of n-butane molecules on a two-dimensional nanomaterial was studied and compared with bulk zeolite. The activation energy barrier for cracking on the nanomaterial was higher than in bulk zeolite due to the lack of confinement. The effects of different zeolite structures on n-butane adsorption and cracking were also explored, revealing that smaller channel sizes led to weaker adsorption and higher activation energy barriers for terminal C-C cracking.

Summary: In this study, the adsorption capability of Ti-doped graphene was investigated for arsenic species As4, As2, and AsH3. Different adsorption behaviors were observed for the three arsenic species, with As4 showing dissociation, As2 forming ionic and covalent bonds, and AsH3 exhibiting weak chemisorption mainly controlled by ionic interactions. The relationship between adsorption activity and electronic structure was explained using the partial d-band center, especially for As2 adsorption on Ti/GS, and Fermi softness was used to describe the adsorption activity of Ti/GS.

Summary: The interface between water and the In-rich InP(001) surface was studied using density functional theory. It was found that single water molecules preferentially attach to three-fold coordinated surface In atoms. Water dissociation is energetically favorable but hindered by an energy barrier that decreases with increasing water coverage. Water films on InP are stabilized by anchoring to surface-bonded hydroxyl groups and show similar structural properties to ice Ih with increasing thickness.

Summary: Stable InP (001) surfaces have occupied valence bands and empty conduction bands, but experimental results show that the surface Fermi level is slightly below the midgap energy, causing surface band bending. Surface defects on P-rich InP (001) surfaces formed from hydrogen desorption are responsible for this discrepancy. These hydrogen-related defects are stable when water is adsorbed, as long as water does not dissociate. Therefore, water exposure does not affect the surface band bending on a flat InP (001) surface.

Summary: This study investigates the DC conductivity in potassium titanyl phosphate (KTP) and its isomorphs, and suggests a method to reduce the overall ionic conductivity in KTP. Gray tracking phenomena are observed in KTP, which leads to decreased ionic conductivity and additional optical absorption. A thermal treatment in an oxygen-rich atmosphere can eliminate gray tracking and restore the ionic conductivity and optical transmission. These findings can guide the selection of materials and treatments for specific applications.

Two adsorption mechanisms, carbene insertion in Si-H bonds and binding to a surface defect, were investigated. The stability of these configurations depended on the hydrogen chemical potential and the molecular side groups. Molecular diffusion was also influenced by the side groups. Adsorption configurations resulted in electronic states within the silicon band gap and a reduction in the work function.

Summary: The third-order susceptibility Chi(3) of lithium niobate (LiNbO3) is calculated using a Berry-phase formulation of the dynamical polarization based on the electronic structure obtained within density-functional theory (DFT). Maximum |Chi zzzz(3)| values of the order of 10-19 m2 V-2 are calculated for photon energies between 1.2 and 2 eV, which are in the lower half of the optical bandgap of lithium niobate. Both free and bound electron (bi)polarons are found to significantly enhance the third-order susceptibility for photon energies below 1 eV.

Summary: In this study, the structural, electronic, and optical properties of TiO2 crystals were calculated using Hubbard U correction and hybrid functional methods in density-functional theory. The results were compared with experimental observations, and it was found that the modified hybrid functionals and DFT + U method can provide accurate atomic structures and electronic structure data. The methods were also applied to study TiO2 amorphous ultra-thin films, and the agreement between the two methods was confirmed even for small details of the optical spectra.

Summary: The adsorption behavior of cyclic (alkyl) (amino) carbenes on the monohydride Si(001) surface is investigated using density functional theory. Two different adsorption mechanisms, carbene insertion in Si-H bonds and binding to a surface defect with missing hydrogen, are studied. The stability of these configurations depends on the hydrogen chemical potential and the molecular side groups. The molecular diffusion is also influenced by the side groups. Some adsorption configurations result in electronic states within the silicon bulk band gap. The work function is significantly reduced upon molecular adsorption.

Summary: The influence of K-doping on the reactive oxygen species and elementary reactions of HCHO catalytic oxidation was investigated using density functional theory (DFT). The introduction of K-doping changed the electronic structures of Ce and O, facilitating the adsorption and activation of HCHO and O2 molecules, enhancing lattice oxygen mobility, and reducing the energy barrier for HCHO oxidation. K-doping also promoted the formation of hydroxyl groups, facilitating HCHO adsorption and oxidation.

Summary: This study investigates Si mass transport and morphological transformations on the Si(111) surface during (root 3 x root 3)-Sn reconstruction formation and Si homoepitaxy. The research shows that the formation of different Sn phases at different temperatures affects the Si island nucleation and monatomic step shift, which in turn impact the morphology of the Sn/Si(111) interface. Electromigration-induced drift of disordered Sn domains leads to enhanced noncompensated Si mass transport and surface roughening.

Summary: Deposition of thallium (Tl) onto the Au/Si(111)5 x 2 reconstruction followed by annealing results in the formation of a surface structure with 4 x 2 periodicity. The immiscibility of Au and Tl leads to the migration of Tl atoms over the Si chains. Thallium donates electrons to the surface, converting the metallic surface into an insulating state and altering the inter-chain distance within the array of Au atomic wires.

Summary: Using ab-initio calculations, the interaction between lead adatom and both clean and doped iron (100) surfaces was investigated. It was found that the lead adatom prefers to adsorb in the hollow site, which is more stable compared to the top and bridge sites, and in this position, it is energetically favorable over the iron adatom. Moreover, lead adsorbed in the hollow site of the iron (100) surface doped with chromium was found to create a more stable system compared to nickel-doped surfaces with an iron adatom in the same position. The study also explored inter-layer distances, bonding mechanisms, magnetic behaviors, and charge density differences. The results provide insights into the role of doping in the interaction between lead adatom and iron surface, and have implications for the analysis of corrosion processes caused by liquid lead.

Summary: Alkaline water electrolysis is a simple and efficient method for renewable hydrogen production, utilizing cheap and abundant transition metals. The catalytic properties of Ni materials are enhanced by the formation of oxidized compounds on the surface. The high electrocatalytic activity of Ni (oxy)-hydroxides is directly related to water intercalation in the passivation layer, supporting the hypothesis of a water mediated OH- diffusion mechanism. The self-organization of the surface structure during passivation layer formation enables high electrode performance.
