Summary: This article introduces multiple-beam grating interferometry, a hybrid technique that combines multiple-beam interference and grating interferometry. The fringes of this interferometry technique follow a general form of Airy formulae, and their period is determined by the phases from grating pitches and laser wavelength. Two crucial parameters, peak transmission and finesse, are defined and investigated to describe the brightness and sharpness of the fringes. The results from both simulation and experiment are consistent, and this technique shows promise for in-plane and multi-dimensional displacement measurements.

Summary: The unusual optical properties of laser-ablated metal surfaces are caused by the excitation of local plasmon resonances in nano- and microstructures, as well as the interaction of these structures through surface plasmon polariton waves. The analytical solution to the problem of surface plasmon polariton excitation is important, and it can be solved by considering the surface geometry as a superposition of harmonic Fourier components. This study demonstrates that the problem can be solved using a method for calculating guided-mode amplitudes in the presence of current sources.

Summary: The study demonstrates control over the spatial and temporal properties of surface plasmon polaritons (SPPs) launched from nanohole arrays in silver, showing that SPPs launched from multiple arrays can interfere at defined spatial positions to form an all-SPP periodic nano-optical grating that evolves as the SPPs propagate. The spatio-temporal characteristics of the optical grating can be tuned through various nanohole array parameters, and the temporal interference of SPPs with different central wavelengths can be tailored through multiperiodic arrays (MPAs) consisting of arrays with different pitches placed adjacent to one another. Temporal interference serves as an encoded signal, where frequency components can be controlled by array properties.

Summary: Titanium oxide is commonly used as an effective catalyst for photo-electrochemical water splitting, but its wide bandgap limits the utilization of visible and near-infrared light. The photosensitization of titanium oxide with plasmonic nanostructures has been proposed as a solution. In this work, a plasmon-based titanium oxide photosensitization method using a gold grating is presented. The gold grating supports the excitation and propagation of surface plasmon polariton wave, resulting in the activation of titanium oxide. Experimental results demonstrate that this structure enables efficient photo-electrochemical water splitting and hydrogen production under near-infrared light irradiation.

Summary: This paper introduces a high-performance and high-sensitivity nanostructured bimetallic optical biosensor based on grating-coupled surface plasmon resonance (GCSPR) technology. The sensor comprehensively considers sensitivity, full width at half peak (FWHM), and dip strength of the absorption peak (DS), and defines the comprehensive evaluation parameter FOM+ by improving the figure of merit (FOM). The performance of the sensor was further enhanced by optimizing the sensor structure and adding an ultra-thin gold layer to prevent silver oxidation. Coating graphene oxide on the bimetallic sensor surface greatly improved the sensitivity and FOM+ by at least 74.7%.

Summary: The effects of A-site transition from Ca2+ to Cd2+ on the microstructure, morphology, and electrical properties of Ca(1-x)CdxCu(3)Ti(4)O(12) thin films were investigated. The films exhibited smooth and compact surfaces without cracks. The transition from Ca2+ to Cd2+ resulted in changes in grain size and electrical properties. In particular, the simultaneous occupancy of A sites by Ca2+ and Cd2+ improved the dielectric and nonlinear properties of Ca1-xCdxCu3Ti4O12 films.

Summary: Cu1_xHoxFeO2 nanoceramics were synthesized by sol-gel method to investigate the influence of vacancy defects and Fe valence state tuning on their magnetic and dielectric properties. XRD and Raman analysis confirmed the formation of single-phase delafossite structure. XPS analysis revealed that Ho3+ substitution could tune the Fe valence state, while positron annihilation lifetime spectroscopy showed that it could effectively tailor the cation vacancies concentration in the interface region. Magnetic measurements indicated that Ho3+ substitution enhanced the magnetic transition temperatures and magnetization, while Cu1_xHoxFeO2 nanoceramics exhibited giant dielectric characteristic attributed to charge ordering of Fe3+ and Fe2+.

Summary: In this study, we propose a novel method for on-chip generation and manipulation of higher-order Poincare sphere beams (HOPBs) by combining metasurface with optical waveguides on a lithium niobate on insulator platform. By using a diatomic geometric metasurface for phase modulation, guided waves are extracted into free space with high signal-to-noise ratio and formed into two orthogonal circularly polarized optical vortices which are linearly superposed into HOPBs. Additionally, a dual-port waveguide crossing is utilized to reconfigure the output states into an arbitrary point on a higher-order Poincare sphere based on in-plane interference of two guided waves. This approach provides a compact solution for generating and manipulating HOPBs and can be further enhanced by employing electro-optical modulation on a lithium niobate waveguide for full tunability.

Summary: In this study, fifteen candidate anthocyanin biosynthesis related MYB (ABRM) proteins were identified from highbush blueberry, including twelve R2R3-MYBs and three 1R-MYBs. The subcellular localization prediction results showed that most of the blueberry ABRMs were nucleus-localized, except for VcRVE8. The gene structure analysis revealed a wide range of exon numbers in the blueberry ABRM genes. The promoters of the blueberry ABRM genes contained various responsive elements related to light, phytohormones, abiotic stress, and plant growth and development. Additionally, the expression analysis showed that VcMYB, VcMYB6, VcMYB23, VcMYBL2, and VcPH4 were abundantly expressed in blueberry fruits, with VcMYB being the highest in red, purple, and blue fruits. The study provides valuable information for future research on anthocyanin biosynthesis related MYBs in blueberry.
