Hydrogen isotope effect on self-organized electron internal transport barrier criticality and role of radial electric field in toroidal plasmas [PDF]

open access: yesScientific Reports, 2022
Self-organized structure formation in magnetically confined plasmas is one of the most attractive subjects in modern experimental physics. Nonequilibrium media are known to often exhibit phenomena that cannot be predicted by superposition of linear ...

Giant Isotope Effect in Metal–Organic Frameworks Boosts Unprecedented Photo‐ and Radio‐Luminescence Enhancement [PDF]

open access: yesAdvanced Science
Isotope effect (IE) has emerged as a powerful strategy for tailoring the photophysical properties of luminescent systems, yet its application in solid materials remains limited.

Four Isotope-Labeled Recombination Pathways of Ozone Formation

open access: yesMolecules, 2021
A theoretical approach is developed for the description of all possible recombination pathways in the ozone forming reaction, without neglecting any process a priori, and without decoupling the individual pathways one from another.

Impact of Deuteration and Temperature on Furan Ring Dynamics

open access: yesMolecules, 2021
Despite significant progress in conformational analysis of cyclic molecules, the number of computational studies is still limited while most of that available in the literature data have been obtained long time ago with outdated methods.

Non-Covalent Isotope Effects

open access: yesThe Journal of Physical Chemistry Letters, 2023
In this Perspective, we present examples of isotope effects that originate from noncovalent interactions, mainly hydrogen bonding, electrostatics, and confinement. They are traditionally widely used in isotopic enrichment processes, as well as in studies of mechanisms of different (bio)chemical and physical phenomena. We then show the emerging areas of

Structural insights into protein folding, stability and activity using in vivo perdeuteration of hen egg-white lysozyme

open access: yesIUCrJ, 2021
This structural and biophysical study exploited a method of perdeuterating hen egg-white lysozyme based on the expression of insoluble protein in Escherichia coli followed by in-column chemical refolding.

Crystal Structure and Thermal Behavior of SbC2O4OH and SbC2O4OD

open access: yesInorganics, 2020
The order of OH groups in the crystal structure of SbC2O4OH, a potential precursor in the synthesis of ternary oxides, was debated. Neutron diffraction on the deuteride SbC2O4OD revealed disordered OD groups with half occupation for deuterium atoms on ...

Deuterated Arachidonic Acid Ameliorates Lipopolysaccharide-Induced Lung Damage in Mice

open access: yesAntioxidants, 2022
Arachidonic acid (ARA) is a major component of lipid bilayers as well as the key substrate for the eicosanoid cascades. ARA is readily oxidized, and its non-enzymatic and enzymatic oxidation products induce inflammatory responses in nearly all tissues ...

Predictive JET current ramp-up modelling using QuaLiKiz-neural-network

open access: yesNuclear Fusion, 2023
This work applies the coupled JINTRAC and QuaLiKiz-neural-network (QLKNN) model on the ohmic current ramp-up phase of a JET D discharge. The chosen scenario exhibits a hollow $T_\mathrm{e}$ profile attributed to core impurity accumulation, which is ...

Stable Isotope Abundance and Fractionation in Human Diseases

open access: yesMetabolites, 2021
The natural abundance of heavy stable isotopes (13C, 15N, 18O, etc.) is now of considerable importance in many research fields, including human physiology. In fact, it varies between tissues and metabolites due to isotope effects in biological processes,
