Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite
Advanced Functional Materials, EarlyView.The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

On scaling laws in scrape-off-layer plasmas
Plasma Physics and Controlled Fusion, 1994 The scaling law in the scrape-off-layer (SOL) plasma is discussed, and the influence of the cross-field thermal conductivity, kappa , is analysed. Analyses are done for the edge temperature, temperature fall-off length and the fluctuation level. The dependencies on the heating power, edge density and safety factor are investigated.

Selected methods of electron-and ion-diagnostics in tokamak scrape-off-layer
Nukleonika, 2015 This invited paper considers reasons why exact measurements of fast electron and ion losses in tokamaks, and particularly i n a scrape-off-layer and near a divertor region, are necessary in order to master nuclear fusion energy production.

Intrinsic toroidal plasma rotation in the scrape-off-layer [PDF]
The origin and nature of intrinsic toroidal plasma rotation in the scrape-off-layer are theoretically investigated. We discuss and analytically estimate three mechanisms that give rise to SOL toroidal rotation: turbulent momentum transport associated ...

Effect of magnetic perturbations on divertor scrape-off width
, 1977 A general method is developed for calculating the width, due to magnetic perturbations, of the scrape-off layer of a tokamak with a divertor. The general method is applied to a simple analytic model of a divertor to indicate the magnitude of the effects ...

Chitin‐Derived Carbon‐Metal Functional Materials
Advanced Functional Materials, EarlyView.Functional carbon materials are synthesized from combination of biopolymer (chitin) and iron precursors. The resultant material exhibits superior surface area and adsorptive properties compared to carbon materials synthesized directly from pure chitin.

On the density decrease in the scrape off layer of the bundle divertor
, 1979 A two-dimensional model is used for caiculating the density decrease in the scrape-off layer of a tokamak plasma with a bundle divertor.
