Article Abstract
In emerging artificial intelligence applications, massive matrix operations require high computing speed and energy efficiency. Optical computing can realize high-speed parallel information processing with ultra-low energy consumption on photonic integrated platforms or in free space, which can well meet these domain-specific demands. In this review, we firstly introduce the principles of photonic matrix computing implemented by three mainstream schemes, and then review the research progress of optical neural networks (ONNs) based on photonic matrix computing. In addition, we discuss the advantages of optical computing architectures over electronic processors as well as current challenges of optical computing and highlight some promising prospects for the future development.

The rapid advancement of three-dimensional (3D) printing technologies has significantly expanded their potential applications such as sensors and detector technology. In this study, the gamma-ray shielding performance of ulexite-doped composite resins fabricated via Digital Light Processing (DLP) 3D printing was experimentally investigated to evaluate radiation attenuation capacity. Composite resins containing different ulexite loadings (0, 1, 3, and 5 wt%) were exposed to gamma rays at energies of 356, 662, 1173, and 1333 keV to evaluate their attenuation characteristics.

Circularly polarized luminescence (CPL) has emerged as a critical technology for anticounterfeiting and optical display applications due to its unique chiroptical properties. We report a multicolor CPL-emitting elastomeric film (P37/PSK@SiO-PDMS) that synergistically combines chiral helical polyacetylene (P37) and a surface-engineered perovskite (PSK@SiO) through hydrogen-bond-directed assembly. Confinement within the PDMS matrix drives P37 to self-assemble into a chiral supramolecular structure through hydrogen bonding, inducing a chiroptical inversion.

Introduction: Guided bone regeneration (GBR) serves as a critical technique in dental implantology, relying heavily on barrier membranes for successful alveolar bone augmentation. Titanium mesh, widely utilized in GBR procedures, faces a high exposure rate that leads to infections and compromised clinical outcomes. While 3D-printed personalized meshes have reduced exposure rates, infection risks persist, necessitating the development of bioactive solutions.

We report the performance of solid-state ceramic supercapacitors (SSCs) based on a novel composite electrolyte comprising aluminum-doped lithium lanthanum titanate perovskite, LiLaTiAlO (Al-doped LLTO), and the ionic liquid 1-ethyl-3-methylimidazolium tetrafluoroborate (EMIM BF). Rietveld refinement of X-ray diffraction data confirms the preservation of the tetragonal perovskite phase after Al substitution, indicating structural stability of the host lattice. X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy further corroborate the successful incorporation of Al without forming secondary phases.

In this work we study the effect of the matrix of the source on the spectrum and on the full energy peak efficiency for low energy photons. Using realistic simulations carried out with PENELOPE 2018, including detector resolution, we show that small angle Compton scattering does contribute to the peak count rate, implying the dependence of the matrix effects on the linear attenuation coefficient μ and also on the scattering cross section. We show that the effect of Compton scattering can be removed from the apparent peak, resulting a "clean" peak depending only on μ.
