Bifurcation from L-mode to internal transport barrier triggered by a magnetic island in tokamak plasmas

Nuclear Fusion
Magnetic islands are believed to be responsible for triggering the internal transport barrier (ITB) around the rational surface and hence improves confinement in magnetic confinement fusion plasma, for more than two decades.

High Energy Electron Confinement in a Magnetic Cusp Configuration

, 2014
We report experimental results validating the concept that plasma confinement is enhanced in a magnetic cusp configuration when beta (plasma pressure/magnetic field pressure) is order of unity.

Progress in toroidal magnetic confinement

Le Journal de Physique Colloques, 1979
This paper will discuss the confinement properties of plasma in magnetic fields which are characterized by their strong toroidal components. In such systems confinement is achieved by the addition of poloidal magnetic fields which are either produced internally by toroidal currents induced in the plasma - internal confinement - or by currents flowing ...

Formation of Stable Amorphous Calcium Phosphate and Collagen Assemblies by a Versatile Spray‐Drying Approach

Advanced Functional Materials, EarlyView.
Amorphous calcium phosphate (ACP) microparticles with long‐term and thermal stability are prepared with or without collagen using a scalable one‐pot spray‐drying process. Under simulated physiological conditions, they crystallize into biomimetic bone mineral and, when combined with collagen, form extrudable, fibrillar bone‐like 3D constructs.
