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

Sci Rep, 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]

Adv Sci (Weinh)
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.

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

IUCrJ, 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.

Deuterated Arachidonic Acid Ameliorates Lipopolysaccharide-Induced Lung Damage in Mice

Antioxidants, 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

Nuclear 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

Metabolites, 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,

Effect of the isotope mass on pedestal structure, transport and stability in D, D/T and T plasmas at similar β N and gas rate in JET-ILW type I ELMy H-modes

Nuclear Fusion, 2023
The work describes the pedestal structure, transport and stability in an effective mass ( A _eff ) scan from pure deuterium to pure tritium plasmas using a type I ELMy H-mode dataset in which key parameters that affect the pedestal behaviour (normalized ...

Anomalous isotope effect in BCS superconductors with two boson modes

New Journal of Physics, 2021
The isotope effect in the superconducting transition temperature is anomalous if the isotope coefficient α < 0 or α > 1/2. In this work, we show that such anomalous behaviors can naturally arise within the Bardeen–Cooper–Schrieffer framework if both ...

Four Isotope-Labeled Recombination Pathways of Ozone Formation

Molecules, 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

Molecules, 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.
