31P‐MRS of the Human Heart at 7 T With an Integrated Whole‐Body 31P Radiofrequency Transmit Coil

NMR in Biomedicine, Volume 39, Issue 4, April 2026.
We demonstrate the use of an integrated whole‐body phosphorus‐31 (31P) radiofrequency transmit coil for 31P‐MR spectroscopic imaging of the human heart at 7 T. Intersession measurement repeatability of the mid‐septal myocardial phosphocreatine (PCr) over adenosine triphosphate (ATP) concentration ratio in normal volunteers was 17.7%.

Multimodal MRI Reveals Cerebral and Vascular Amyloid‐Driven Myeloarchitectural Disorganization in a Mouse Model of Alzheimer's Disease

NMR in Biomedicine, Volume 39, Issue 4, April 2026.
This study investigates the effect of cerebral and vascular (beta‐amyloid) Aβ on regional myeloarchitecture and lipid composition in a murine model of Alzheimer's disease (AD). The study highlights the feasibility of quantitative MRI and chemical exchange saturation transfer (CEST) imaging to identify multiple biophysical mechanisms involved in ...

At the core of the interaction: Probing charged side chains in flexible protein regions with simultaneous nuclear magnetic resonance experiments

Protein Science, Volume 35, Issue 4, April 2026.
Abstract Charged amino acid side chains are crucial mediators of biomolecular recognition, but their characterization by nuclear magnetic resonance (NMR) is often hindered by conformational and solvent exchange, particularly for arginine guanidinium groups.

Conundrums of Localized Surface Plasmon Resonance Biosensors

Small, Volume 22, Issue 19, 1 April 2026.
Localized surface plasmon resonance (LSPR) biosensing faces fundamental conundrums arising from finite field decay lengths, environmental cross‐sensitivities, and batch variability. Competing surface, bulk, and electrostatic effects can induce red or blue spectral shifts, complicating quantification, reproducibility, and interpretation in complex or ...

Application of the differential quadrature numeric technique to study deflection and stability of ultra-small-scale plates

The stability and deflection of nanoplates are numerically investigated in this paper using the differential quadrature method (DQM). In many scientific disciplines, particularly solid mechanics, nonlinear partial differential equations are frequently employed as models to explain intricate physical phenomena.

Experimental Characterization and Modeling of High Hole Mobility GeSn Quantum Wells: The Role of Alloy Disorder Scattering

Small Science, Volume 6, Issue 4, April 2026.
This study reports record‐high hole mobility in undoped GeSn quantum wells, validated through magnetotransport measurements. By modeling the transport properties, the authors discover that alloy scattering in their material is significantly weaker than predicted for random alloys and previously studied materials.
