Toroidal rotation in RF heated JET plasmas

, 2009
Observations of bulk plasma rotation in radio frequency (RF) heated JET discharges are reported. This study is concentrated on RF heated L-mode plasmas. In particular, the toroidal rotation profiles in plasmas heated by ion cyclotron resonance frequency (

Isotope Effects on Intrinsic Toroidal Rotation and Rotation Reversals

, 2022
JET is the largest tokamak in operation and the main link between smaller machines, where intrinsic rotation has been mostly studied, and ITER the next step in fusion research. While the main ion in present tokamak plasmas is a single hydrogen isotope, mainly Deuterium (D) in JET, future nuclear fusion machines, such as ITER, will operate with a ...

First 20 Years of Orbitrap Mass Spectrometry as the Mainstream Analytical Technique

Mass Spectrometry Reviews, Volume 45, Issue 6, Page 1064-1086, November/December 2026.
ABSTRACT This review traces the first 20 years of Orbitrap mass spectrometry as a mainstream high‑resolution and accurate‑mass (HR/AM) technology. It outlines the historical development of the Orbitrap analyzer, the evolution of major instrument families, and the key technological innovations that enabled its widespread adoption. Particular emphasis is

Beyond Bactericidal: Plasma Surface Engineering to Defeat Food Matrix‐Conditioning Layers

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 6, November 2026.
ABSTRACT The persistence of foodborne pathogens on industrial food contact surfaces continues to challenge global food safety despite advances in sanitation technologies. A central limitation of current antimicrobial strategies lies in their validation under simplified laboratory conditions that overlook the physicochemically driven formation of food ...

A Heuristic Exploration of Zonal Flow-like Structures in the Presence of Toroidal Rotation in a Non-Inertial Frame

Plasma
The mechanisms by which rotation influences zonal flows (ZFs) in plasma are incompletely understood, presenting a significant challenge in the study of plasma dynamics.

Drift‐Resonance Driven by Field Line Resonance Gradients: A Mechanism for Non‐Dispersive Microinjection Events

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Ultra‐low‐frequency waves in the magnetosphere often produce field line resonances with strong spatial gradients in wave amplitude. We analyze a form of drift resonance driven by these gradients near the resonant field line. This mechanism differs fundamentally from conventional gradient‐ and curvature‐driven drift resonance and predicts an ...

Study of radial field dependent flows in inboard limited Aditya-U plasmas using EMC3-Eirene simulations

Nuclear Fusion
The intrinsically generated plasma rotation in magnetically confined tokamak plasmas has implications for a number of edge and core phenomena. In recent Aditya-U tokamak circular plasma discharges with plasma current of range (142–170) kA, the toroidal ...

Deep Reinforcement Learning Inverse Design of Dielectric Metasurfaces Supporting Dual Quasi‐BIC Resonances

Nanophotonics, Volume 15, Issue 19, 13 October 2026.
A deep reinforcement‐learning framework designs dielectric metasurfaces supporting dual quasi‐BIC resonances under tightly coupled multi‐objective constraints. By combining D3QN, rollout‐based lookahead, reward normalization, and prioritized replay, the method stabilizes the optimization of the resonance wavelength, quality factor, and near‐field ...

Triple-band transparency effect by multiple couplings based on toroidal dipole resonance

Materials Research Express
We explored multiple couplings properties in composite metastructure. One part is the asymmetric double rings, supporting the narrow toroidal dipole resonance, and the other component is an upright rod that excites the broad electric dipole resonance ...

Organic Mixed‐Valence π‐Electron Systems—Current Status and Challenges

Asian Journal of Organic Chemistry, Volume 15, Issue 10, October 2026.
This review discusses the progress and challenges in organic mixed‐valence π‐electron systems, focusing on trends such as the exploration of multi‐redox‐centered mixed‐valence multi‐radical states arising from the interplay between charge transfer and spin interactions and the realization of novel mixed‐valence states through the effective utilization ...
