Characterisation of ethylene adsorption on model skeletal cobalt catalysts by inelastic and quasi-elastic neutron scattering

open access: yesCatalysis Communications, 2022
To bridge the materials gap of single crystal work on the Fischer-Tropsch chain-growth mechanism, ethylene adsorption on a model skeletal cobalt catalyst was studied. Speciation and mobility of surface species were characterised using inelastic (INS) and

Hydration-dependent dynamics of water in calcium-silicate-hydrate: A QENS study by global model.

open access: yesColloids and Surfaces B: Biointerfaces, 2018
HYPOTHESIS In a saturated cement paste, there are three different types of water: the structural water chemically reacted with cement, the constrained water absorbed to the surface of the pores, and the free water in the center of the pores.

Assessment of pepsin diffusion within casein gels by quasi-elastic neutron scattering (QENS) and fluorescence recovery after photobleaching (FRAP) [PDF]

open access: yes, 2022
International audienceBackground: Protein digestion under gastric conditions is influenced by the activity of the enzyme pepsin. With a limited penetration depth, pepsin-induced protein hydrolysis mainly occurs at the surface of the gel particles ...

Molecular Dynamics of Lysozyme Amyloid Polymorphs Studied by Incoherent Neutron Scattering

open access: yesFrontiers in Molecular Biosciences, 2022
Lysozyme amyloidosis is a hereditary disease, which is characterized by the deposition of lysozyme amyloid fibrils in various internal organs. It is known that lysozyme fibrils show polymorphism and that polymorphs formed at near-neutral pH have the ...

Anomalous Structure of Liquid Bi Studied by Coherent QENS and Time-space Correlation Analysis

open access: yeshamon, 2019
Bismuth (Bi) has a double-layered structure based on Peierls distortion in crystalline phase. Complicated static structure in liquid phase which cannot be interpreted by a simple packing model has been conjectured that Peierls distortion may remain even ...

Dynamical Behavior of Disordered Regions in Disease-Related Proteins Revealed by Quasielastic Neutron Scattering

open access: yesMedicina, 2022
Background and Objectives: Intrinsically disordered proteins (IDPs) and proteins containing intrinsically disordered regions (IDRs) are known to be involved in various human diseases. Since the IDPs/IDRs are fluctuating between many structural substrates,

DDIapp—A Web‐Based Application for Static Drug–Drug Interaction Assessment

open access: yesCPT: Pharmacometrics &Systems Pharmacology, Volume 15, Issue 8, August 2026.
ABSTRACT In this work we describe the development of a web‐based application for static drug–drug interaction (DDI) risk assessment in accordance with the International Council for Harmonization (ICH) M12 guidance. The app was built using the Shiny for Python framework and it employs a modular mathematical modeling structure that incorporates models ...
