NMR imaging as a tool for studying the diffusion and co-diffusion of gases in zeolite catalysts [PDF]

, 2005
1H NMR imaging is a powerful technique for studying the diffusion of pure hydrocarbons (for example benzene and n-hexane) during their adsorption in or desorption from a fixed bed of zeolite crystallites.

A Rare Instance of Adult Medulloblastoma Presenting Imaging Heterogeneity Correlating With Molecular Subtypes and Anatomical Locations

Clinical Case Reports, Volume 14, Issue 10, October 2026.
ABSTRACT We report an adult medulloblastoma presenting as two imaging‐distinct lesions: a uniformly enhancing torcular mass (WNT‐activated) and a non‐enhancing cerebellar tumor (SHH‐activated). A cohort analysis confirmed torcular location favors uniform enhancement, mimicking meningioma.

Antisolvent crystallization of lithium hydroxide monohydrate: Significant factors and kinetics analysis

The Canadian Journal of Chemical Engineering, Volume 104, Issue 10, Page 5383-5396, October 2026.
Abstract Crystallization is the final stage in lithium hydroxide monohydrate (LiOH · H2O) production, and antisolvent crystallization offers a lower‐energy route compared with evaporative methods. In this study, we investigated bench‐scale ethanol‐based antisolvent crystallization of LiOH · H2O, and identified the significant impact parameter via a ...

RSM‐Based Optimization and Sensitivity Analysis of Radiative MHD Tangent Hyperbolic Nanofluid Flow Over an Exponentially Stretching Porous Sheet With Variable Heat and Mass Fluxes

Engineering Reports, Volume 8, Issue 10, October 2026.
The viscous flow of an incompressible hydromagnetic tangent hyperbolic nanofluid over an exponentially stretching porous sheet is investigated, incorporating variable heat and mass fluxes, Brownian motion, thermophoresis, and thermal radiation. Governing PDEs are transformed into ODEs via similarity transformations and solved numerically using MATLAB's

Magnetically Controlled Mixed Convection Nanofluid Flow With Slip and Suction: Implications for Thermal System Design

Engineering Reports, Volume 8, Issue 10, October 2026.
This work presents a comprehensive computational investigation of magneto hydrodynamic mixed convection nanofluid flow over a stretching sheet by incorporating the coupled effects of velocity and thermal slip, suction, Brownian motion, thermophoresis, thermal radiation, viscous dissipation, and mixed convection. The study provides new insights into the

A Novel De Novo MTM1 Insertion Frameshift Variant Causes X‐Linked Myotubular Myopathy in a Chinese Female

Molecular Genetics &Genomic Medicine, Volume 14, Issue 10, October 2026.
A 24‐year‐old heterozygous woman presented with lifelong hypotonia and slowly progressive, asymmetric axial and limb‐girdle weakness with facial/ocular involvement and restrictive ventilatory impairment (FVC 53.12% predicted). Multimodal evaluation (EMG, muscle MRI, and whole‐exome sequencing [WES]) identified a de novo MTM1 frameshift variant ...
