Organic Electrochemical Transistor Channel Materials: Copolymerization Versus Physical Mixing of Glycolated and Alkoxylated Polymers

open access: yesAdvanced Functional Materials, Volume 36, Issue 20, 9 March 2026.
This work discusses the use of blended channel materials in OECTs. It explores how mixing glycolated and alkoxylated polymers in various ratios offers a simpler and more efficient route to tuning OECT properties. The performance of the polymer blends is compared to the corresponding copolymers, demonstrating similar OECT characteristics, swelling ...

Depth‐Invariant High‐Resolution Optical Coherence Tomography Angiography

open access: yesAdvanced Photonics Research, Volume 7, Issue 3, March 2026.
Optical coherence tomography angiography (OCTA) has become an indispensable tool for visualizing and quantifying in vivo blood flow due to its motion‐contrast‐based label‐free flow detection capabilities. However, in various applications, its effectiveness is hindered by signal degradation due to scattering, absorption, and depth‐dependent defocus ...

Real‐Time In Vivo Cellular‐Level Imaging During Puncture

open access: yesAdvanced Science, Volume 13, Issue 14, 9 March 2026.
We present an artificial‐intelligence‐empowered integrative‐light‐field microendoscopy (AIM) needle that delivers real‐time in vivo, diffraction‐limited cellular‐level imaging during puncture and visualizes layered microstructures along the needle path. As a microscopic complement to CT/ultrasound, it improves sampling localization and adds preliminary

Dynamic Retinal Pathology in Glaucoma Progression Revealed by High‐Resolution Functional Imaging In Vivo

open access: yesLaser &Photonics Reviews, Volume 20, Issue 5, 6 March 2026.
In this work, we investigated the dynamic retinal pathology of glaucoma from onset to late stages through longitudinal in vivo high‐resolution imaging in a silicone oil‐induced ocular hypertension (SOHU) glaucoma mouse model. We developed an optimized adaptive optics two‐photon excitation fluorescence microscopy (AO‐TPEFM) technique for morphological ...

Visualization of small vibrations inside an MRI scanner using video motion amplification

open access: yesMedical Physics, Volume 53, Issue 3, March 2026.
Abstract Background Diffusion‐weighted magnetic resonance imaging (DW‐MRI) acquisition requires the application of strong magnetic field gradients, which can induce mechanical vibrations in tissues or phantoms, potentially leading to signal loss or degradation.

Blinking Optical Tweezers for Atom Rearrangements

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 3, March 2026.
The work introduces an energy‐efficient method for holding and rearranging an N ×$\times$ M array of atoms using only N optical tweezers, using just 1M of the optical power per atom. In the proof‐of‐concept experiments, single blinking tweezer holds M = 9 atoms and further facilitates rearrangement M = 4 ∼$\sim$ 5 atoms in various configurations ...

High‐Precision Measurement of Time Delay with Frequency‐Resolved Hong‐Ou‐Mandel Interference of Weak Coherent States

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 3, March 2026.
High‐precision time‐delay measurements are demonstrated using frequency‐resolved Hong‐Ou Mandel (HOM) interference with weak coherent states. The method, by exploiting the quantum eraser phenomenon, achieves low uncertainty even for delays exceeding the photon coherence time, where traditional HOM interferometry fails, thus confirming theoretical ...
