Summary: Understanding the relationship between molecular structure and optical properties of rare earth doped luminescent materials is important for creating advanced active laser media. Rare earth ions can also be used to study the molecular structure of the host material. This study combines molecular dynamics simulations, Judd-Ofelt theory, and UV-vis-NIR absorption spectroscopy to investigate the local molecular structure surrounding doped rare earth ions in glasses with different compositions. The results show that the composition of the glass affects the absorption spectra and coordination numbers of the rare earth ions.

Summary: The characteristics of rare earth (RE3+) doped phosphate glasses with different dopants were studied. The glasses were characterized by optical reflectance, Raman scattering, and solid-state NMR spectroscopy. Incorporation of Nb2O5 affected the optical and physical properties of the glasses, while having little impact on the emission properties of RE3+. These glasses may serve as potential candidates for energy conversion from infrared or UV to the visible region and as infrared solid-state emitters.

Summary: This study investigates aluminoborosilicate glasses with La2O3 and CeO2, examining their structural, thermal, and dielectric properties. The presence of La2O3 influences the network structure of the glass, while the presence of Q(3) and Q(4) results in a more compact structure. Changes in glass transition temperature, thermal stability parameters, and glass density are attributed to variations in bond strength, non-bridge oxygen content, field strength, and molar mass of La2O3.

Summary: Zn2-xLaxSiO4 (x = 0.00, 0.02, 0.04, and 0.06) materials with varying weight percentages of lanthanum (La) in zinc silicate (Zn2SiO4) were synthesized using the sol-gel process. The effect of La dopant on the structure, morphology, and optical characteristics of Zn2SiO4 was investigated through various analytical and spectroscopical techniques. The results showed that La3+ ions were incorporated into Zn2SiO4, significantly affecting its crystallinity, morphology, and optical properties. The luminescent peak intensity and lifetime of La-doped Zn2SiO4 were also analyzed.

Summary: The study investigated the photoluminescence properties of (La2O3)(0.05)(As2S3)(0.90)(Er2O3)(0.05) combination in the visible region at different temperatures. It was found that the inclusion of two impurities led to the disappearance of the maximum peak belonging to As2S3 and a sharp increase in the photoluminescence spectrum intensity. The sharp increase in photoluminescence intensity was attributed to the interatomic transition of Er3+ ion in the 600-750 nm region.

Summary: This study experimentally investigates a Cu planar wire array (PWA) in air and water, showing that PWA has higher electric power peak, faster vaporization and ionization processes, and higher energy-density state compared to a single-wire case. In air and water, the single-wire load tends to develop a transverse stratified structure, while PWA is dominated by uneven energy deposition among wires.

Summary: This study utilizes the acoustoelectric effect to localize and decode dipole signals with high accuracy. The results show that a single dipole can be localized with an error of less than 0.3 mm, and the decoding accuracy is higher than 0.94. Double dipoles with an interval of 0.4 mm or more can also be localized, but the localization error increases as the interval decreases, and the decoding accuracy decreases as the frequency of dipoles decreases.

Summary: In this study, the discharge characteristics and heating mechanisms of argon helicon plasma in different wave coupled modes with and without blue core were investigated. The results showed the existence of at least two distinct wave coupled modes, with one having a significant blue core and the other without. The emission intensity and electron density were measured, and it was found that the ion line intensity was dependent on both electron density and temperature, while the atom line intensity tended to be saturated in wave coupled modes due to neutral depletion. Theoretical analysis revealed that helicon waves were the dominant mechanism of power deposition or central heating of electrons in both modes.

Summary: In this study, the researchers revealed for the first time that the acetylation level of ATG4B at lysine residue 39 (K39) plays a crucial role in regulating its activity and autophagy. The deacetylation of ATG4B K39 by SIRT2 enhances ATG4B activity and autophagic flux, which can be countered by EP300/p300. Starvation treatment promotes the deacetylation of ATG4B K39 by suppressing EP300 and activating SIRT2, leading to the initiation of autophagy. The findings suggest that acetylation-mediated regulation of ATG4B activity is involved in the response to nutritional deficiency.

Summary: This study investigates the stability of high-performance nonfullerene acceptors in a charged state using a spectro-electrochemical technique. The results show that the molecules in the charged state undergo discoloration, which can be partially recovered. The degree of irreversibility is associated with the halogen substituents at the end groups. The stability of the charged state can be improved by fine-tuning the molecular structures, and high carrier mobility is a key factor in achieving better stability for practical applications.

Summary: This study investigates the phase stability, elastic modulus, and hardness of ternary nitride Ti1-xAlxN. It is found that the hardness increases with the Al content x. The cubic B1 structure is more stable for x < about 0.75, while the hexagonal structure (B4) is more stable for x > about 0.75. The composition dependent hardness and phase decomposition contribute to the convex shaped hardness curve of Ti1-xAlxN.

Summary: This report uses rigorous calculations based on density functional theory to study the piezoelectric and elastic properties of wurtzite aluminum nitride (w-AlN) with single- and co-alloying by Hf (or Zr) and Sc. The research finds that the (HfSc)0.375Al0.625N and (ZrSc)0.375Al0.625N with stable wurtzite phase have a large piezoelectric coefficient d33 of 49.18 pC/N and 47.00 pC/N, respectively. However, the piezoelectric voltage constant g33 and electromechanical coupling constant k233 of HfAlN, ZrAlN, HfScAlN, and ZrScAlN are smaller than that of ScAlN, which is attributed to the large dielectric constant epsilon 33 of Hf (or Zr) alloying samples. Furthermore, the calculations of internal parameter u and bond angle alpha elucidate the brittle-to-ductile transformation in alloying w-AlN crystal structure. Electronic structure calculations show that the bandgap decreases almost linearly with the increase of alloying concentration, and the Hf (or Zr) alloying compounds become n-type semiconductors due to the existing high-charge states.

Summary: This work presents a multilayer film structure that uses optical resonance to prepare highly efficient and saturated red, green, and blue transmittance colors. Numerical simulations and analysis show that the structure can produce R, G, and B colors with a purity comparable to standard RGB colors, while maintaining efficient transmission efficiency and obtaining a rich variety of structural colors. Additionally, a metallic interlayer is introduced to selectively suppress resonances in the short-wavelength region, improving the purity of the red color. The study also investigates the effect of the incidence angle on color purity and transmission efficiency.

Summary: Solubility property is of great interest in chemical, physical, pharmaceutical, material, and environmental sciences. Understanding the intrinsic reason behind solubility behavior is a fascinating task. The theoretical relation between binary mutual solubility and liquid-liquid interfacial tension has been derived, where the partitioning of solute molecules between two coexisting liquid phases is determined by the transfer free energy per unit segment for a chain-like solute molecule expressed in terms of solute-solvent interfacial tension. This general theory of solubility is in good agreement with experimental results for binary mutual solubility and molar transfer free energy of solute molecules.

Summary: The influence of ZrOn matrix stoichiometry on the electrical and magnetoresistive properties of Fe-Zr-O nanocomposites has been studied. It was found that the magnetoresistive effect is not observed in composites with oxygen lack, while composites with oxygen excess show magnetoresistive effect and increased resistivity. Magnetoresistivity in composites with oxygen lack only appears after heat treatment. These results can be explained by the difference in the density of localized states in the oxide matrix of the composites and the ratio between two types of conductivity.
