Knife-edge diffraction of scalar and vector vortex light

open access: yesAPL Photonics
Various methods have been introduced to measure the orbital angular momentum (OAM) of light, from fork holograms to Dove prism interferometers, from tilted lenses to triangular apertures—each with its own benefits and limitations.

New‐Generation Integrated Devices: Multiple‐Energy Utilization and Integration Systems Based on Perovskite Photovoltaics

open access: yesEcoEnergy, Volume 4, Issue 5, October 2026.
This review highlights emerging integrated energy systems based on perovskite photovoltaics, including PSC–thermoelectric, photovoltaic–electrochemical, self‐charging, and building‐integrated architectures. By coupling multiple energy conversion and storage pathways, these multifunctional platforms enable enhanced solar utilization, improved stability,

Particle Size Measurement of Organic Nanocarriers: A Case Study Using Polyacrylate‐Based Polymer Nanocarriers

open access: yesSmall Science, Volume 6, Issue 10, October 2026.
Sensitivity, detection limits and applicability of size measurement techniques to polymer nanocarriers (PNCs) are investigated. PTA and DCS do not detect PNCs <50 nm and PTA requires adapting concentrations to each PNC, challenging comparisons. Spherical assumptions challenge interpretation by DLS, PTA, and DCS. Cryo‐TEM detects PNCs <50 nm.

Sulfur‐Free Ultrahigh‐Refractive‐Index Polymers Enabled by Densely Packed Oxygen‐Bridged Dibenzofuran‐Cardo Architectures

open access: yesAdvanced Functional Materials, Volume 36, Issue 78, 28 September 2026.
A new class of sulfur‐free, oxygen‐bridged dibenzofuran‐based polymers is developed for ultrahigh‐refractive‐index applications. The rigid π‐extended architecture and enhanced molecular polarizability enable exceptional optical performance, combining refractive indices up to 1.848 with high Abbe numbers and full visible transparency. This work offers a

Optical Loss Due to Diffraction by Concentrator Fresnel Lenses

open access: yes, 2015
Fresnel lenses are widely used in concentrating photovoltaic (CPV) systems as a primary optical element. They focus sunlight on small solar cells or on the entrance apertures of secondary optical elements.

Detailed Shallow Shear Velocity Structure in the Nankai Trough From Ambient Noise Differential Adjoint Tomography: Implications for Earthquake Generation Mechanisms

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Seismic and aseismic slip has been reported in the Nankai Trough. In this study we apply ambient noise differential adjoint tomography to obtain a high‐resolution S‐wave velocity (Vs) model in the Nankai Trough. The Vs in the very shallow imbricate thrust zone is higher than that on both the seaward and landward sides.
