Summary: We calculate the lattice dielectric function of strongly anharmonic rutile TiO2 using ab initio anharmonic lattice dynamics methods. By accurately calculating the I' point phonons, we show that the self-consistent approach including third-order and fourth-order anharmonicity provides better agreement with experimental measurements than a perturbative approach. Our results demonstrate the contribution of four-phonon scattering and the identification of unidentified peaks in the dielectric function as two-phonon processes. This work highlights the importance of the self-consistent approach in predicting optical properties of highly anharmonic materials.

Summary: In this study, the phonon properties and the origin of anisotropy in monolayer biphenylene were investigated using first-principles calculations and theoretical analysis. The results showed that monolayer biphenylene has multiple Raman-active and infrared-active modes, and a Raman-active single phonon mode with a high frequency, suggesting potential applications. Furthermore, the inconsistent motion speed and different intensities of hybridization between the carbon atoms were found to be responsible for the direction-dependent thermal and elastic properties in biphenylene.

Summary: Silicon carbide (SiC) is widely used in electronic and optoelectronic applications as an indirect-gap semiconductor material. The computational cost has hindered theoretical investigations of phonon-assisted absorption, despite the existence of experimental measurements for more than 50 years. In this study, we calculate the temperature-dependent optical absorption spectra of common SiC polytypes using first-principles approaches. Our results agree with experimental absorption coefficients and predict the temperature dependence by considering the band gap. Considering the electronic energy renormalization due to temperature is important for improving the prediction of phonon-assisted absorption in SiC. Our insights can be applied to predict the optical spectra of other indirect-gap semiconductors and less common SiC polytypes in general.

Summary: The structure stability, mechanical properties, and thermodynamic behaviors of Al4Si6La3 compound were investigated in a wide pressure range of 0-100 GPa using first-principles calculations based on density functional theory. The results showed that the compound was thermodynamically stable at 0 GPa but became unstable with increasing pressure. The compound exhibited ductile nature at pressures up to 100 GPa, and the Debye temperature and minimum thermal conductivity were improved with increasing pressure. The analysis of electronic structures revealed the formation of covalent bonds between Al-Si and La-Si in the compound, while Al-La formed antibonding states at different pressures.

Summary: The electronic, magnetic, and vibrational properties of Nb-doped LiCoO2 were investigated using density functional theory. Nb doping induced mid-gap states and a mixture of Co3+ and Co2+ oxidation states in LiCoO2, leading to the presence of a non-zero magnetic moment. The phonon spectra of Nb-doped LiCoO2 exhibited negative frequencies that could be corrected by introducing electron correlation. These findings suggest that Nb-doped LiCoO2 has potential applications in electrical transport properties and memristors.

Summary: In this paper, the secrecy outage probability of a relay aided multiuser network is analyzed in the presence of an eavesdropper and co-channel interference (CCI). Two relay aided multiuser scheduling (RMS) schemes are proposed to improve the secrecy outage performance, and their closed-form expressions are derived. Numerical results show that the proposed RMS schemes outperform the baseline round-robin scheduling (RRRS) scheme, with the full CSI based RMS achieving the best secrecy outage performance. It is also found that the number of users has a significant impact on the secrecy outage performance of the proposed schemes, while the RRRS scheme remains unchanged.

Summary: First-principles calculations were conducted on Ce-N system under high pressures, investigating electronic band, phonon spectra, elastic properties, and electron-phonon couplings of Ce-N compounds. R3m-CeN6 was found stable above 50 GPa with a hardness of 25.57 GPa, while a novel composition of R3-CeN8 with a hardness of 43.97 GPa was discovered at higher N atom condensation. Additionally, R3-CeN8 exhibited superconductivity with an estimated critical temperature Tc of 31.72 K at 180 GPa. The calculated elastic properties revealed a gravimetric energy density of 3.81 kJ/g for R3-CeN8, surpassing traditional energy materials. This study enriches the theoretical understanding of the Ce-N system and offers guidance for experimental synthesis of cerium nitrides compounds.

Summary: Pd3P2S8 is a semiconductor containing Kagome lattices with various physical phenomena. Structural searches revealed four phases, two in the P3?m1 space group (P3?m1 -1 and P3?m1 -2) and two in the C2/m space group (C2/m -1 and C2/m -2), with all but C2/m -2 phase being dynamically stable. Electron-phonon calculations confirmed that both phases exhibit superconductivity, with the P3?m1 -1 phase undergoing a semiconductor-to-superconductor transition and achieving a maximum Tc of 9.13 K at 70 GPa. This study expands the options for studying superconductivity in materials with Kagome lattices.

Summary: An efficient method for phosphate removal from wastewater is urgently needed due to the environmental issue caused by excessive phosphorus. In this study, calcium aluminum layered double hydroxides (CaAl-LDHs) and six amino acid intercalated calcium aluminum layered double hydroxides (CaAl-amino acid-LDHs) were prepared and compared for their phosphate adsorption performance. L-Aspartic acid intercalated calcium aluminum layered double hydroxides (CaAl-Asp-LDHs) exhibited the highest phosphate adsorption capacity and faster removal rate compared to CaAl-LDHs. The phosphate adsorption mechanism on CaAl-Asp-LDHs involved electrostatic attraction, hydrogen bonds, complexation, and ion exchange. This environmentally friendly material shows promising potential for efficient phosphate removal from aquatic environments.

Summary: Studying the diffusion properties of hydrogen is important for designing new proton conductors. In the past, the chemical diffusion coefficient of hydrogen in proton conductors was usually obtained through a manual calculation method, resulting in difficulty in controlling the calculation accuracy. To address this issue, a mathematical algorithm and C language computer program were developed to calculate the chemical diffusion coefficient based on Fick's second law and Romberg numerical integral. The algorithm showed high precision and powerful computing function, and has the potential to replace the manual calculation method in calculating the chemical diffusion coefficient for hydrogen in proton conductors.
