Panoramic voltage‐sensitive optical mapping of contracting hearts using cooperative multiview motion tracking with 12 cameras

The Journal of Physiology, EarlyView.
Abstact figure legend A panoramic 3D optical mapping system was developed, enabling imaging of action potential waves across the entire strongly deforming ventricular surface of beating isolated hearts. The system comprises 12 high‐speed cameras and a soccerball‐shaped imaging chamber with 48 light‐emitting diodes (LEDs).

A Müller Glia‐Retinal Pigment Epithelium Apical Network Surrounding Cone Outer Segments in Fish and Mouse

Glia, Volume 74, Issue 12, December 2026.
Müller glia and the retinal pigment epithelium interact around cone outer segment in the subretinal space of both zebrafish and mouse. The contacts are established early during development but subsequent to outer segment emergence. ABSTRACT Homeostasis of the vertebrate retina critically depends on two non‐neuronal cell populations, Müller glia and the

Chemical Characterisation of Steam‐Distilled Essential Oils From Lemongrass (Cymbopogon citratus Stapf) and Ginger Rhizomes (Zingiber officinale Roscoe) Using FTIR and GC‐MS: Comparison of Phytochemical Composition

Phytochemicals in Food and Medicine, Volume 1, Issue 4, December 2026.
Illustration of essential oil extraction coupled with characterisation. ABSTRACT Essential oils from lemongrass and ginger rhizomes contain bioactive compounds with potential for nutraceutical and pharmaceutical applications. In this study, essential oils were extracted from ginger rhizomes and lemongrass by the steam distillation method, using a ...

Core–Shell Molecularly Imprinted Polymer@SiO2@Fe3O4 for Low‐Cost and Selective Electrochemical Sensing of Paraquat

ChemElectroChem, Volume 13, Issue 21, 3 November 2026.
A low‐cost electrochemical sensor for paraquat (PQ) was developed by modifying a screen‐printed carbon electrode with a PQ‐selective core–shell molecularly imprinted polymer (MIP) synthesized via precipitation polymerization. Coupled with adsorptive stripping voltammetry (AdSV), the MIP‐modified sensor enables highly sensitive and selective detection ...

Insights Into the Electrochemical Response of Commercial Carbon Screen‐Printed Electrodes

ChemElectroChem, Volume 13, Issue 21, 3 November 2026.
Commercial carbon‐based screen‐printed electrodes are systematically compared through electrochemical, wettability, topographical, and surface characterization analyses. The study demonstrates how electrode type, surface heterogeneity, measurement repeatability, and experimental configuration (bulk solution vs.

Improved Serotonin Measurement With Fast‐Scan Cyclic Voltammetry: Analysis of Electrode Fouling by Fluoxetine in Live Brain Tissue

Analysis &Sensing, Volume 6, Issue 6, November 2026.
Fluoxetine (Prozac) is a drug that is useful for treating depression and for studying serotonin system function in live brain tissue. Unfortunately, the use of fluoxetine tends to foul electrodes when using fast‐scan cyclic voltammetry. In this work, we evaluated an extended serotonin waveform as a useful approach for mitigating fouling by fluoxetine ...

Phosphorylated Chitosan‐Based Ionogels for Quasi‐Solid‐State Supercapacitors With Activated Carbon Electrodes

Batteries &Supercaps, Volume 9, Issue 11, November 2026.
This work investigates a phosphorylated chitosan/EMIMDCA ionogel as a fluorine‐free quasi‐solid‐state electrolyte for supercapacitors. The optimized ionogel achieved an ionic conductivity of 5.3 ± 0.3 mS cm−1 at 30 °C. The symmetric activated carbon device retained 76% of its initial capacitance after 10,000 cycles, over twice the stability of neat ...

Experimental methods in chemical engineering: Cyclic voltammetry—CV

The Canadian Journal of Chemical Engineering, Volume 104, Issue 11, Page 5776-5827, November 2026.
Abstract Cyclic voltammetry (CV) is a foundational electroanalytical technique for investigating redox behaviour and evaluating material performance across fields such as molecular electrochemistry, electrocatalysis, sensing, and energy storage. Despite its widespread use, a gap remains between formal electrochemical theory and the practical data ...
