Summary: This study focuses on the role of water molecules in driving chiral separation on the surface when RNA base uracil selfassembles into homochiral structures upon water exposure. The findings provide insights into the general role of water molecules in the origin of homochirality in living systems, with implications for other biologically relevant molecules such as amino acids and sugars.

Summary: Using experimental techniques and theoretical calculations, this study investigated the lattice and electronic structures of Au atoms adsorbed on the Pb(111) surface at low temperature. It was found that the Au atoms formed an ultra-thin superstructure, Au/Pb(111)-3 x 3. Three surface-state bands were induced within and adjacent to the bulk projected band gap of Pb(111). The S-1 surface state showed an anisotropic Rashba splitting.

Summary: Gold-based catalysts have attracted significant attention in heterogeneous catalysis due to their ability to catalyze reactions at low temperatures in oxidative environments. This study investigates the adsorption and intermolecular behavior of small alcohols on Au(111) defect sites, revealing distinct adsorption features and the linear relationship between desorption energy and carbon chain length. The study also highlights the influence of molecular packing structures on intermolecular interactions and the differences in adsorption energy at different sites.

Summary: Interfacial interaction between supported catalysts and the underlying substrate is crucial in catalysis. This study demonstrates that the interaction between Cr2O7 and Au can be weakened by applying an electric field, allowing for manipulation of the individual clusters. However, surface alloying with Cu enhances the interaction and makes the manipulation difficult.

Summary: Chemisorbed species, particularly sulfur, can enhance the decay rate of 2D Au islands on metal surfaces, leading to surface pitting and reconstruction. The formation and diffusion of Au-S complexes contribute to the enhanced coarsening of Au islands at lower sulfur coverages.

Summary: The study investigates the growth mechanism of mono- and bilayer iron oxide on the gold substrate, demonstrating the strong interfacial Fe-Au bonds and significant charge transfer. The second layer of FeO exhibits a modulated ellipsoidal Moire pattern due to the strong Fe-Fe bonds and varying interlayer distances at different sites, promoting future research on metal oxide-substrate interactions in catalysis.

Summary: The formation of substoichiometric titanium oxide dendritic structures on Au(111) terraces is studied computationally and found to follow the classical fractal formation mechanism of diffusion-limited aggregation (DLA). Gas-phase oxide cluster structures, optimized globally, are sampled in various landing formations on gold surfaces, and shown to favor isomers that drive polymerization to form Brownian tree fractal structures. The mobility of Ti3O5 monomers is found to be extremely high, with diffusion barriers of 0.21 eV or less. Polymerization of these monomers is energetically favorable and irreversible on the 111 terrace due to bonding stabilization, but geometrically impossible to propagate along the step edge. Simulated scanning tunneling microscopy (STM) images show a strong resemblance to experimental observations. On the other hand, the aggregation of Ti3O6 as wires along step edges is explained by the affinity of oxygen to step edges, statistical arguments for aggregation entropy at the step, as well as low barriers for monomer diffusion and polymerization.

Summary: This study used boron-doped diamond (BDD) anode as a prototype to investigate water oxidation and 'OH production mechanism in electrochemical advanced oxidation process (EAOP). The research revealed that BDD anode is more favorable for 'OH production than O2 generation. Additionally, doping with elements such as N, P, S, and F in diamond enhances the energy of water oxidation reactions, making O2 generation more difficult and increasing the Faradic efficiency of 'OH production.

Summary: A comprehensive study was conducted on the properties of donor-acceptor (D-A) bilayer structures, revealing that the characteristics of the bilayer structure on Au substrate are independent of the deposition sequence, while strong chemisorption occurs on Cu substrate, pinning down the PEN molecules.

Summary: This study investigates the water formation reaction on Pd surfaces using first-principles density functional theory calculations and kinetic Monte Carlo simulations. The results show that the reaction rate is influenced by surface steps and point defects, and the main reaction path is temperature-dependent.

Summary: Spontaneous generation of reactive oxygen species (ROS) occurs when water vapor contacts hydrogen-bonded hydroxyl groups on a silicate surface, which is confirmed by time-resolved FT-IR spectroscopy. The involvement of water vapor in ROS generation is further supported by studying the reaction of D2O vapor and hydroxyl groups on a silicate surface. It is proposed that the change of the hydrogen-bonding network and electron transfer onto the silicate surface during water vapor-solid contact process contribute to ROS production.

Summary: In this study, we investigated the size-dependent transition between the CO2 reduction reaction (CO2RR) and H-2 evolution reaction (HER) selectivity for Ag nanoparticle electrocatalysts in the sub-5 nm range. Our results showed that 3.7 nm-diameter particles exhibited the highest combination of CO2RR activity and selectivity. Smaller diameter particles favored HER due to a high population of Ag edge sites, while larger diameter particles had decreased catalyst utilization due to a growing population of electrochemically inaccessible, interior atoms.
