Summary: This work investigates the luminescent properties of Tris (8-hydroxyquinoline) aluminium (Alq3) thin layers using conventional spectral methods and advanced time-resolved luminescent spectroscopy. Alq3 films with a thickness of 100-300 nm were deposited on silicon substrates using PVD method. The structural properties of Alq3 layers were studied using scanning electronic microscopy and X-ray diffraction. The luminescence spectra of Alq3 in the green-yellow range confirm the complex structure of the emission centers associated with the Al3+ molecule and 8-hydroxyquinoline ligands.

Summary: Functional antifouling coatings are developing as a direction for marine antifouling coatings. In this study, tris-(8-hydroxyquinoline) aluminum modified with titanium dioxide (AlQ3:TiO2) coatings were prepared, which exhibited photocatalytic antibacterial and fluorescent algae inhibition under visible irradiation. The AlQ3:TiO2 coatings showed high antibacterial activity against E. coli with an inhibition efficiency of up to 97.51%. Additionally, the reactive oxygen species (ROS) and weak fluorescence generated under visible irradiation effectively inhibited the growth and settlement of algae. Based on comprehensive antifouling experiments and electrochemical characterization, a possible antifouling mechanism for AlQ3:TiO2 coatings is proposed.

Summary: This paper investigates the properties of muoniated radicals in organic semiconductors through experiments and calculations. The results show that muons primarily bind to secondary carbon atoms of the quinolate rings in Alq(3) and 8hq, with localized spin density. In contrast to previous studies, no evidence of radicals with muon hyperfine coupling constants of 23 or 91 MHz is found in Alq(3). The findings support the interaction between muons and electrons in organic systems, and muoniated radicals in Alq(3) have shorter lifetimes.

Summary: Aluminium batteries (AlBs) have great potential as a feasible energy storage technology, thanks to their high capacity, low cost, abundance, and recyclability. However, the presence of an insulating oxide layer on the Al metal anode necessitates the use of special non-aqueous acidic electrolytes to enable reversible plating and stripping of Al. The formation of a porous and complex passivation layer under certain conditions poses challenges for stable interfaces and the successful implementation of AlBs.

Summary: The addition of Ag nanostructures in Alq(3) significantly enhances its photoluminescence, making it suitable for emissive layers in organic light emitting diodes (OLEDs). Continuous improvement of Alq(3) materials is crucial during the commercialization of OLEDs. The incorporation of Ag nanostructures improves the photophysical properties through the plasmon-exciton coupling effect. Ag nanoparticles enhance absorption ability, while Ag nanowires coexist with localized surface plasmons and propagating surface plasmons, resulting in a 5.3-fold enhancement in photoluminescence intensity and a narrowing of the full-width at half maximum (FWHM) by 10 nm. Temperature-dependent measurements show an increase in plasmonic density of states (DOS) with decreasing temperature, and the introduction of Ag nanostructures accelerates thermal exchange. Excitation intensity (EI)-dependent measurements further demonstrate effective suppression of thermal accumulation. Ag nanostructures also affect the y coordinates in the International Commission on Illumination (CIE), leading to higher brightness. The color temperature of an Ag nanowires-embedded composite is suitable for daylight-type fluorescent OLEDs.

Summary: Hysteresis effects in ionic-electronic devices can be utilized to develop switching memory devices for information storage and brain-like computation. Halide perovskite devices exhibit frequent hysteresis in current-voltage curves, which can be used to construct effective memristors. By introducing capacitive coupling in the slow relaxation variable, the extended neuron-style model is able to explain the transition from capacitor to inductor in impedance spectroscopy of MAPbBr solar cells and memristors in the dark, and it also generates new types of oscillating systems with a truly negative capacitance distinct from the usual inductive effect.

Summary: Redox-active moieties assembled on metallic interfaces follow quantum mechanical rules, with the quantum capacitance of the interface playing a key role in electron transfer dynamics. Modifying these interfaces with biological receptors has advantages for miniaturized electroanalytical devices, and using peptide-based redox-active moieties has shown promising results. In this work, different ferrocene-tagged peptide structures were used to form self-assembled monolayers on gold for electroanalytical assays, with the Gly-peptide structure showing the best performance for sensing the NS1 DENV biomarker. The study highlights the importance of surface chemistry in sensing interfaces and the advantages of using peptides as biosensor components.

Summary: Hysteresis effects in ionic-electronic devices can be used to develop switching memory devices for information storage and brain-like computation. Halide perovskite devices exhibit frequent hysteresis in current-voltage curves, which can be utilized to build effective memristors. These phenomena can be described by nonlinear differential equations involving current, voltage, and internal state variables similar to the Hodgkin-Huxley model for action potentials in neurons. Furthermore, introducing a capacitive coupling in the slow relaxation variable extends the neuron-style models to explain observations in impedance spectroscopy of MAPbBr solar cells and memristors.

Summary: The complexes of He, Ne, Ar, Kr, and Xe with B3N3H6 were investigated using MP2, CCSD(T), and SAPT ab initio methods. The complexes can be described as mono-, di-, and tri-coordinated to the N atoms, with stability following the order N-mono < N-di < N-tri. The interactions are dominated by dispersion and the binding energies are within the range of 1 or 2 kcal mol(-1). The results were compared with a recent DFT study on larger BN sheets complexes [Phys. Chem. Chem. Phys. 24 (2022) 2554-2566.].

Summary: It has been found that the introduction of buffer layers improves the electrical performance of solid oxide fuel cells (SSOFCs). In this study, varying ratios of Gd-doped CeO2 were used as buffer layers in YSZ-based SSOFCs. The results demonstrate that the performance of SSOFCs is enhanced when a buffer layer is added, with the highest performance achieved using Ce0.8Gd0.2O2-delta (GDC20) as the buffer layer. This suggests that the use of GDC series buffer layers is an attractive strategy to optimize performance loss due to electrolyte-electrode interactions.
