Summary: This study detected the hot electron transition of noble materials to catalysis accelerated by localized surface plasmon resonances (LSPRs) using in situ irradiated X-ray photoelectron spectroscopy (ISI-XPS).

Summary: Researchers report a facile plasmonic approach for electrically controlled spatial modulation of exciton emissions in a WS2 monolayer. The emission routing is enabled by the resonance coupling between WS2 excitons and multipole plasmon modes in individual silver nanorods, and can be modulated by the doping level of the WS2 monolayer.

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: Excitons in a transition-metal dichalcogenide monolayer can be modulated through strain and controlled with spatial and spectral control. In this study, strain-localized excitons in a WS2 monolayer were generated and detected by covering the monolayer on individual Au nanodisks or nanorods. Enhanced emission from the strain-localized excitons was observed at room temperature, and the emission intensity and peak energy could be adjusted by the size of the nanodisks. Furthermore, the excitation and emission polarization of the strain-localized excitons could be modulated by anisotropic Au nanorods.

Summary: This study discusses the influence of controllable carriers on localized surface plasmon resonance (LSPR) in (Ag)x(MoO3)y composites, as verified by SERS testing and UV-Vis-NIR absorption spectra. It was found that the LSPR absorption wavelength can be easily tuned from 950 to 735 nm by changing the sputtering power of MoO3. The relationship between carrier density and SERS intensity change caused by electromagnetic enhancement was investigated using Hall effect measurements. These findings provide insights into tunable LSPR and the contribution of electromagnetic effects to SERS.

Summary: Zero-dimensional (0D) scintillation materials are of great interest for the fabrication of flexible high-energy radiation scintillation screens. Challenges still persist in the development of 0D scintillators, but a strategy based on metal nanoclusters shows promise in overcoming these limitations. This work demonstrates the synthesis and self-assembly of atomically precise nanoclusters with high phosphorescence quantum yield, AIEE behavior, and intense radioluminescence. The self-assembled nanoclusters can be used as building blocks for flexible particle-deposited scintillation films with high-resolution X-ray imaging performance.

Summary: Here, we present a concise and universal strategy for achieving photoactivated ultralong phosphorescence at room temperature through stereo-hindrance engineering. The dynamic photoactivated phosphorescence behavior is attributed to the suppression of non-radiative transitions and improvement of spin-orbit coupling (SOC) through the variation of molecular conformation. This study not only outlines a principle for designing dynamic phosphorescent materials, but also extends their utility in intelligent sensors and robotics.

Summary: The three-proton intercalation mechanism in α-molybdenum trioxide is uncovered using a specially designed electrolyte, leading to an improved specific discharge capacity. Experimental and theoretical evidence verifies the semiconductor-to-metal transition behavior and the expansion of lattice interlayers after proton trapping. Fracture behavior is observed during the proton intercalation process, creating diffusion channels for hydronium ions. Additionally, an additional redox behavior at low potential is observed, contributing to an enhanced specific discharge capacity of α-molybdenum trioxide.

Summary: This article introduces a broadband outphasing power amplifier (OPA) design with a reconfigurable output combiner. T-type matching structures loaded with varactors replace transmission lines for broadband performance. Bias voltage applied to the varactors is adjusted to compensate for frequency dispersion effects. A postmatching network (PMN) is further implemented for correct reactance compensation and impedance in a large frequency band, improving the bandwidth and drain efficiency (DE) of the OPA.

Summary: This study reveals the significant contribution of hot phonons to the photo-induced transient bandgap renormalization in MAPbBr(3) single crystals, as evidenced by asymmetric spectral evolutions and transient reflection spectral shifts in the picosecond timescale. Moreover, it identifies a strong correlation between surface charge carrier diffusion and transient bandgap renormalization in time. These findings highlight the need to re-evaluate current theories on photo-induced bandgap renormalization and provide a new approach for precisely controlling the optical and electronic properties of perovskite materials, enabling the design and fabrication of high-performance optoelectronic devices with exceptional efficiency and unique properties.

Summary: In this research, an ultrahigh sensitivity microwave microfluidic sensor is proposed to determine the dielectric properties of a liquid sample. The sensor consists of metal strips connected to a microstrip line through metallic vias, and an interdigital capacitor structure for strong electric field confinement. The loaded liquid sample interacts with the field, affecting the frequency offset and peak attenuation, which can be used to extract features of unknown liquid. Experimental results demonstrate that dual-mode measurement improves the sensitivity of the sensor by 43% compared to single-mode measurement, utilizing both odd- and even-mode frequency offset.

Summary: Nowadays, LiDAR plays a crucial role in environmental perception technology. However, due to the sparsity and disorder of point cloud data, LiDAR is unable to detect some obstructed objects and may mistakenly consider incorrect and unimportant objects as target objects. To address these issues, a transformer-based architecture is proposed to connect voxels by introducing neighborhood sparse attention. This architecture demonstrates significant improvements in computational efficiency compared to traditional baselines on the KITTI3D dataset.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
