A targeted antiferromagnetic nanoprobe for ultra‐sensitive magnetic resonance imaging detection of sub‐millimeter esophageal tumors

BMEMat, EarlyView.
We developed a cyclo‐RGD peptide‐conjugated antiferromagnetic nanoparticle (RANP) as a targeted T1 contrast agent. Under 9 T MRI conditions, RANP exhibited an r1 value of 1.88 mM−1 s−1 and a low r2/r1 ratio of 1.84, enabling the detection of esophageal tumors as small as 0.8 mm in vivo. Abstract Early, non‐invasive detection of esophageal cancer at sub‐

Real‐time biosensing of Parkinson's disease biomarkers via NIR‐activated upconversion nanoparticles

BMEMat, EarlyView.
Schematic illustration of the luminescence resonance energy transfer‐driven core‐shell‐shell UCNPs (cssUCNPs@Fluo4) nanoprobe for simultaneous monitoring of Ca²⁺‐temperature dynamics in Parkinson's disease models. Abstract Parkinson's disease (PD) is a progressive neurodegenerative disorder with incompletely understood pathophysiology, necessitating ...

Comprehensive Characterization of Spelt Wheat and Common Wheat Protein and Viscosity Traits Under Different Field Management Systems

Cereal Chemistry, EarlyView.
ABSTRACT Background There is an increasing interest in healthier, nutrient‐rich foods so alternative grains produced in smaller quantities—including spelt wheat (Triticum spelta L.)—have once again become the focus of consumers. At the same time, the scientific proof of these claims is incomplete.

Oxide Interface of Gallium‐Based Liquid Metals: Beneficial Bridge or Hidden Risk?

ChemistryEurope, EarlyView.
Discussion on oxide interfaces in gallium‐based liquid metals have concentrated on their properties, behaviors, and related applications. However, the molecular mechanisms underlying effects, as well as the differences between the presence and absence of the oxide layer, have been less thoroughly discussed.

Effect of soiling agents on disinfection efficacy of a pulsed‐xenon UV lamp towards Listeria monocytogenes on stainless steel surfaces

The Canadian Journal of Chemical Engineering, EarlyView.
This study quantifies the effects of different soils found in the food processing environment on the efficiency of pulsed‐xenon UV disinfection. Abstract Listeria monocytogenes is a foodborne illness that poses a significant threat to human health in young, old, and immunocompromised persons and accordingly, prevention of Listeria contamination is of ...

In‐situ asphaltene capture with iron oxide nanoparticles in steam‐assisted gravity drainage (SAGD) for improved recovery and partial upgrading of bitumen

The Canadian Journal of Chemical Engineering, EarlyView.
Key improvements obtained by incorporating nanoparticles into a lab‐scale SAGD process configuration. The bar plots show enhanced oil recovery, reduced viscosity, and increased asphaltene adsorption in nanoparticle‐assisted scenarios compared with conventional SAGD.

How Amino Acids Intercalate in CaFe Layered Double Hydroxides: A Combined RIXS and NEXAFS Study

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Intercalation of amino acids in layered double hydroxides offers a road to functional (bio)catalysts. With resonant soft x‐ray spectroscopy we probe the electronic structure of these systems and observe activation and passivation of electronic states as well as bond formation between the amino acid and the LDH upon intercalation.
