Summary: Single-crystalline niobium pentoxide nanowires were synthesized by thermal oxidation of niobium substrates in mild vacuum, with amorphous Al2O3 shells of varying thicknesses deposited on top of the wires. The Young's modulus of the core-shell nanowires changed after adding the Al2O3 shell, with different effects observed depending on the thickness of the shell. This change in Young's modulus is likely associated with the structural disordering of the Al2O3 shell.

Summary: Through density functional theory calculations, the effects of different metal oxides adsorbed on the anatase TiO2 (101) surface were studied, indicating that a small amount of CuO increases the reactivity of the catalyst, but the overall catalytic effect is inferior to those with FeO or MnO. Catalysts containing FeO are more stable than those with only CuO or MnO, with higher FeO adsorption ratio leading to increased stability of the catalyst structure.

Summary: The demand for polymers has been increasing over the past decade due to their unique properties. This has led mechanical engineers to study material damage problems, as partial or total ruptures resulting from these problems often cause accidents. This paper investigates the impact of strain rate on the damage of chlorinated polyvinyl chloride compounds through tensile tests conducted at different strain rates. Two damage models are developed based on the concept of stress, which enable the description and prediction of the mechanical behavior and damage development of chlorinated polyvinyl chloride.

Summary: The study on hydrated clusters Co(H2O)(n)(-) in gas phase using DFT coupled with stochastic kicking method reveals that the global minimum structure of Co(H2O)(n)(-) exhibits a low-symmetry pattern. The Co- ion tends to be located at the vertex site of the water molecular clusters to reduce repulsion with O atom. These results demonstrate that the formation of these low-lying isomers is determined by the delicate balance between ion-water and water-water interactions.

Summary: The potential of monoclinic Li3Co2SbO6 as a lithium-ion battery electrode material was studied using density functional theory (DFT). Li3Co2SbO6 crystallizes in space group C2/m (space group number 12). The deintercalation process can proceed in two different ways: Li3→Li1→Li0 and Li3→Li2→Li0. However, there is no phase change with Li2→Li1 due to its unique structural arrangements. The formation energies of Li2Co2SbO6 and LiCo2SbO6 were evaluated and found to be 0.0462 eV and 0.025 eV, respectively, suggesting that it may not be possible to extract all Li+ ions from pristine Li3Co2SbO6. The electronic band gap of Li3Co2SbO6 (-3.28 eV) is lower than that of LiFePO4. A stable voltage plateau of -4.1 V was achieved for the extraction of multiple Li+ ions from Li3Co2SbO6. Additionally, a 2D diffusion path with a path length of -3.1 A was identified in Li3Co2SbO6. It is possible that Li3Co2SbO6 may exceed the efficiency of LiFePO4 if multiple Li+ ions can be extracted from it.

Summary: With the increasing number of scientific papers, it becomes difficult for researchers to keep up with recent articles in their field. In this study, a new unsupervised method using topic modeling is proposed to classify publications, with a focus on Density Functional Theory (DFT). By analyzing word similarity, the method attributes each publication to a specific topic and provides interesting observations on connections between topics and publishers, journals, country or year of publication. This approach is general and can be applied to analyze publication and citation trends in other areas of study beyond DFT.

Summary: The reduced density matrix functional theory is a powerful tool for studying properties of ground states of strongly interacting quantum many body systems, especially Bose-Einstein condensation and systems of strongly correlated electrons. It has been shown that the density functional in these systems exhibits a repulsive gradient, known as the Bose-Einstein condensation force, which is universal for different types of pair-interaction and non-homogeneous gases. The theory has also been extended to fermionic systems, showing the existence of a similar repulsive gradient in the fermionic RDMFT.

Summary: Through a combination of experiments and simulations, the study revealed significant morphological and mass changes in the PEDOT:Tos film during oxidation/reduction processes, confirming the replacement of tosylate by chloride ions. The relative mass change between the most oxidized and reduced states was around 10-14%, and the overall material loss during voltammetry cycles indicated that a portion of the material expelled during reduction did not return during subsequent oxidation. This research provides crucial insights into the molecular processes underlying the redox process of PEDOT:Tos film, essential for improving and evaluating the performance of bioelectronic devices.

Summary: In this study, we investigated the electronic, magnetic, and thermal properties of two-dimensional binary MnX2 and Janus MnXX' monolayers using first-principles and anisotropic Heisenberg models. The monolayers exhibit stable ferromagnetic ground state with strength of magnetic anisotropy determined by the type of chalcogen atoms. The spin-polarized electronic structure depends strongly on the chalcogen atoms, ranging from semiconductor to metallic states. The dispersion relation of magnetic excited states was obtained using the linear order Holstein-Primakoff transformation. The Curie temperature was found to be high for Mn dichalcogenides, and the phonon and magnon contributions to the heat capacity were estimated at low temperature.

Summary: Low-dimensional materials have provided new opportunities for emerging science and technological applications. The discovery of two-dimensional monolayers with long-range magnetic order has attracted significant attention. The challenge lies in effectively exploring different magnetic configurations in these 2D materials. However, the computational cost of analyzing a large number of compounds at the ab initio level is prohibitively high. To address this, a practical approach combining density functional theory and machine learning techniques is utilized. The results demonstrate the dependence of electronic screening and magnetic transition temperature in 2D monolayers on the type of non-magnetic ligand atoms.

Summary: In this study, the optoelectronic properties of heterobilayers formed with monolayer SiGe and Janus Ga2SeTe have been investigated using first principles calculations. It was found that the Dirac cone of monolayer SiGe was preserved in both pristine and strained heterobilayers. The Schottky barrier height of the SiGe/Ga2SeTe heterobilayer was initially n-type and became p-type or ohmic contact under strain. Three twisted heterobilayer systems were also examined, and the interlayer misorientation was determined. In the presence of tensile or compressive strains, the imaginary part of the dielectric function spectrum slightly shifted to the infrared or ultraviolet regions, respectively.

Summary: In this study, we investigated the electronic, mechanical, and vibrational properties of Pb1-xSnxO monolayer alloys and Janus PbSnO monolayer using first-principles calculations. It was found that the band gap values of the materials can be tuned by varying the host atom composition by foreign atoms. The non-linearity in the band gap values is attributed to electronegativity and atomic radius differences between Pb and Sn atoms. Our theoretical predictions will guide the experimental realization of these monolayer alloys for various applications.

Summary: First-principles electronic structure calculations under DFT were performed to investigate the gas detection capabilities of the 2D Janus SnSSe monolayer for CO, NO, NO2, NH3, and O2, considering different sites. By including van der Waals interactions, it was found that NO, NO2, and NH3 can strongly adsorb onto the SnSSe monolayer with large adsorption energies. The variation of electronic structures and partial density of states were discussed. Therefore, our results provide a theoretical basis and important explanation for the potential applications of SnSSe monolayer in gas sensing.

Summary: We studied the magnetic phase transition at finite temperatures in hexagonal MnX (X = N, P, As, and Sb) monolayers using first-principles calculations and the second-order Holstein-Primakoff approximation of the anisotropic Heisenberg model. The Curie temperature of MnX monolayers depends on their atomic structures, with the MnN monolayer having a magnetic easy axis out of the plane and the other three (MnP, MnAs, and MnSb) monolayers having an in-plane easy axis with a close-to-zero Curie temperature. The inclusion of magnon-magnon interaction decreases the Curie temperature by softening the magnetic excitation energy and reducing the magnon energy gap at the I' point, which is crucial for the long-range magnetic order at finite temperatures in two-dimensional monolayers.

Summary: In this study, the room-temperature long-range antiferromagnetic order in the Fe2C monolayer was investigated using first-principles calculations and Green's function analysis. The Fe2C monolayer was found to be a semimetal with out-of-plane antiferromagnetic order between two Fe planes. By calculating the temperature-dependent antiferromagnetic magnon energy and spin correlation function, the sublattice magnetization and magnetic phase transition in monolayer Fe2C were evaluated. Furthermore, the effects of an external magnetic field on the antiferromagnetic Fe2C monolayer along the easy axis were investigated, revealing phase transitions from antiferromagnetic to spin-flop and spin-flop to paramagnetic at low temperatures. The Neel temperature and critical values of the magnetic field strength for these transitions were also estimated.
