Comparison of Calorimetry and NMR Relaxometry Measurements of Epoxy Cure Kinetics

Journal of Polymer Science, Volume 64, Issue 18, Page 4001-4011, 15 September 2026.
Single‐sided NMR monitors epoxy cure in three DGEBA/diamine systems, alongside benchmark DSC measurements. Fitting both datasets to a Kamal‐Malkin kinetic model shows NMR‐derived rate constants typically exceed DSC values, revealing an offset between gelation and chemical conversion.

Self‐Assembled Inorganic Nanomembrane Tubes: Rolled‐Up Piezoelectrics for Microacoustic Wave‐Based Actuators and Sensors

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
This study demonstrates a self‐assembly process to generate free‐standing piezoelectric nanomembranes, forming ultracompact microtubular acoustic wave sensors and actuators. The miniaturized 3D piezoelectric platform reported in this work can be applied in telecommunication, energy harvesting, and acoustofluidics. Moreover, the 3D self‐assembly can add

Intravital Multimodal Imaging of Human Cortical Organoid Transplantation in a Mouse Model of Chronic Stroke

Advanced Science, Volume 13, Issue 52, 18 September 2026.
A multimodal intravital imaging platform enables longitudinal tracking of human cortical organoids transplanted into chronic stroke lesions. By combining surgical microscopy, MRI, bioluminescence imaging, and two‐photon fluorescence microscopy, the platform captures graft placement, viability dynamics, and cellular‐scale morphology in vivo, offering a ...

Non‐Invasive Assessment of Endothelial Dysfunction and Arterial Stiffness in Fontan Circulation

European Journal of Clinical Investigation, Volume 56, Issue 9, September 2026.
The Fontan procedure is the definitive treatment for complex congenital heart disease, creating a circulation without a subpulmonary ventricle. This altered hemodynamic state negatively affects endothelial function, contributing to progressive organ dysfunction and long‐term morbidity.

Reconfigurable intelligent surface enabled programmable antenna chamber: Concept and preliminary experiments

Electronics Letters
Antenna chambers are RF‐shielded enclosures which are required for antenna and radio performance measurements. Typically, anechoic chambers (ACs) are used for measuring directional metrics (e.g.

Anechoic and reverberation chamber design and measurements [PDF]

Two different chambers are studied in this thesis: the anechoic chamber (AC) and the reverberation chamber (RC). The AC has been developed for many years, while in the past few years RC has emerged as a promising facility not just in electromagnetic ...

Reverberation enhancement for small rooms

, 2012
Reverberation enhancement is a technology which allows the reverberation time of a room to be increased through the use of an electronic system. These systems have traditionally been applied to improve the acoustics of large concert halls but the ...

Infective Endocarditis Diagnosed by Emergency Physicians Using Cardiac POCUS: A Case Series

Australasian Journal of Ultrasound in Medicine, Volume 29, Issue 3, August 2026.
ABSTRACT Introduction Emergency physicians (EPs) are acquiring ever‐increasing expertise in cardiac point‐of‐care ultrasound (POCUS). We compiled this case series to demonstrate current practice by EPs diagnosing infective endocarditis (IE) using POCUS.

Reverberation Chamber Modeling Based on Image Theory: Investigation in the Pulse Regime

, 2010
WOSInternational audienceIn this paper we propose a straight- forward 3D time domain model of a reverberation chamber (RC) based on image theory. This model allows one to describe the earliest moments of an arbi- trary waveform in an RC.

On‐site pilot‐scale advanced oxidation pretreatment of hospital wastewater: assessment of pharmaceuticals, pathogens, antibiotic resistance genes and acute ecotoxicity

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 8, Page 1478-1491, August 2026.
Abstract BACKGROUND Hospital premises generate wastewater containing a wide spectrum of contaminants, such as pharmaceutically active compounds (PhACs), antibiotic resistance genes (ARGs) and pathogenic microorganisms, whilst plenty of them are classified under the antibiotic resistant bacteria (ΑRΒ) category.
