Gyrokinetic analysis and simulation of pedestals, to identify the culprits for energy losses using fingerprints

open access: yes, 2019
Fusion performance in tokamaks hinges critically on the efficacy of the Edge Transport Barrier (ETB) at suppressing energy losses. The new concept of fingerprints is introduced to identify the instabilities that cause the transport losses in the ETB of ...

Magnetothermal‐Triggered Response and Self‐Healing of Recyclable and Reprocessable Nanocomposites for Actuation Systems

open access: yesAdvanced Functional Materials, EarlyView.
Developing recyclable materials for magnetic robotics that combine rapid response and self‐healing properties is challenging. Hence, this study focuses on the integration of magnetothermal nanoparticles into a dynamic sorbitol‐based vitrimer, a recyclable composite capable of remote actuation and self‐healing by magnetic heating.

Application of non-integer-n RMP coil current waveform for ELM control in JA DEMO

open access: yesNuclear Fusion
We have studied the resonant magnetic perturbation (RMP) coil concept for edge localized mode (ELM) suppression in JA DEMO, a design concept of a steady-state tokamak demonstration reactor, based on the vacuum magnetic model.

Observation of lobes near the X-point in resonant magnetic perturbation experiments on MAST

open access: yes, 2012
The application of non-axisymmetric resonant magnetic perturbations (RMPs) with a toroidal mode number n=6 in the MAST tokamak produces a significant reduction in plasma energy loss associated with type-I Edge Localized Modes (ELMs), the first such ...

The Relationships Between ELM Suppression, Pedestal Profiles, and Lithium Wall Coatings in NSTX [PDF]

open access: yes, 2011
Recently in the National Spherical Torus Experiment (NSTX), increasing lithium wall coatings suppressed edge localized modes (ELMs), gradually but not quite monotonically. This work details profile and stability analysis as ELMs disappeared throughout the lithium scan.

The simulation of ELM suppression by ion cyclotron resonance heating in EAST using BOUT++

open access: yesNuclear Fusion, 2022
Abstract Edge localized modes (ELMs) are completely suppressed by ion cyclotron resonant heating (ICRH) during H-mode discharge, which is first observed in the Experimental Advanced Superconducting Tokamak (EAST). The electromagnetic turbulence model in the BOUT++ framework is applied to the simulations, with the aim of obtaining the key

Exploring an Alternative to mRNA Vaccine Cold Chain Storage: MRNA‐Lipid Nanoparticle Stability When Dried in a Polymer Matrix

open access: yesAdvanced Functional Materials, EarlyView.
The nanostructure, size, and function of mRNA‐loaded lipid nanoparticles are evaluated before drying, within polymer microneedles, and after rehydration. The results reveal the polymer and LNP loadings required to recover nanostructure and preserve the delivery performance in dry‐state formulations.

Influence of n = 4 RMPs on pedestal structure and stability in EAST

open access: yesNuclear Fusion
Changes of pedestal structure and stability caused by n = 4 resonant magnetic perturbations (RMPs) for control of Edge Localized Modes (ELMs) in the EAST tokamak in a target plasma close to the ITER high- Q scenario are studied in this paper.

Density compensation with pellet fueling during ELM suppression with n = 4 RMP on metal-wall EAST tokamak

open access: yesNuclear Materials and Energy
Pellet injection is the most promising fueling method to achieve a deep particle deposition for future fusion reactors. On metal-wall EAST tokamak, a full density compensation has been achieved by the pellet fueling during ELM suppression with n = 4 RMP ...

Deciphering the Role of Cancer Stem Cells in Breast Cancer Brain Colonization Using a Novel Patient‐Derived Model

open access: yesAdvanced Healthcare Materials, EarlyView.
This study shows that stem‐like cells isolated from breast cancer brain metastases drive the spread and growth of tumors in the brain. Among them, a highly adhesive subgroup initiates metastasis and resists many drugs. By closely reflecting patient tumors, these models help identify new targets and improve the development of effective treatments ...
