Summary: Molybdenum disulfide (MoS2) is a promising alternative for the anode of Li-ion batteries due to its high theoretical capacity and layered structure. To address issues such as low electrical conductivity, high volume change, and complicated synthesis, MoS2 flakes/amorphous carbon hybrids (MoS2/C) are proposed for application as anodes. The exceptional performance of MoS2/C hybrids is attributed to the carbon network acting as a buffer layer to mitigate the volume change of MoS2 for improved electrochemical performance in Li+ storage applications.

Summary: In this research, adsorption of Li-ions on anatase nanotubes was studied using molecular dynamics simulations. It was found that Li-ions can adsorb on the nanotubes without causing significant volume changes, enhancing the cycle life of the anodes. Increasing temperature led to an initial increase in adsorbed ions, which then stabilized, but a further increase in temperature caused a decrease in adsorbed ions over time.

Summary: Density functional theory calculations were used to study phase transformations, Li+ diffusion, and charge-transfer reactions in LixTiO2. It was found that in amorphous TiO2, the energy barrier for Li+ diffusion decreases with increasing Li+ fraction, with longer Li-Ti and Li-O interactions having lower insertion energies and higher migration barriers. Amorphous TiO2 exhibits both surface and bulk storage mechanisms due to its disordered atomic arrangement and increased Li+ diffusivity at higher fractions.

Summary: In this study, carbon matrix derived from sunflower seed husks was prepared using ammonium persulfate as a catalyst. The carbon was then combined with anatase TiO2 to form a composite material. The composite material exhibited uniform distribution of titanium dioxide in nanosphere activated carbon, with a spherical structure, high specific surface area, and average pore diameter. When used as an anode in lithium-ion batteries, the composite material showed stable discharge specific capacity and high capacity retention after cycling.

Summary: This study investigated the structures of two Se chains confined inside single-walled carbon nanotubes (SWCNTs), revealing that the chains were linear and parallel. The covalent bond between Se and SWCNT was found to be stronger than that between Se and trigonal Se (t-Se). The interaction between chains was attributed to the overlap of electronic orbitals, and the disappearance of this overlap in the encapsulated Se chains enhanced the covalent bonds.

Our results indicate that the inclusion of spin orbit coupling has a significant impact on the electronic band structure and spin order, making it promising for spintronic applications. We found different topological states in these compounds and observed enhanced power factor in YPtBi with the inclusion of SOC.

Summary: In this study, we elucidate the hopping mechanism of hydrogen at intermediate temperature using a combination of experimental data and theoretical calculations. We find that the transition from thermal hopping to quantum tunneling is attributed to resonant tunneling, which is achieved through the resonant tunneling of discrete vibrational states between the edge octahedral site and the tetrahedral site. We also demonstrate that the tunneling rate can be tuned by energy level matching.

Summary: Graphene quantum dots (GQDs) with quantum confinement and size effects show great potential for sensing applications. This computational study investigates the adsorption performance of pristine and transition metal-doped coronene GQDs to hazardous gases. The results suggest that doping with chromium (Cr) or nickel (Ni) enhances the gas adsorption performance, with Cr-doped GQDs showing strong interaction with gas molecules and potential as a gas remover, and Ni-doped GQDs showing potential as a CNCl sensor.

Summary: Fe-based nanowires containing nonmagnetic elements, fabricated using a pulse electrodeposition method in porous anodic alumina membranes, exhibit magnetic tunability. The magnetic properties of Fe100-xSnx NW arrays, with a diameter of about 35 nm, such as coercivity and squareness values, decrease with increasing Sn content. The structure of the FeSn NWs, dominated by Fe or FeSn alloy crystal phase, can be either single domain or pseudo-single domain states depending on the Sn content.
