Applications of the Diffuse Double Layer
Particulate Science and Technology, 2002Studies of the diffuse double layer have entered an exciting phase due to advances made in fundamental areas of charged solid-liquid systems and the utility of this parameter in soil chemistry and material science. This review discusses the relevance of the Langmuirian approach and the application of the DLVO theory when attractive and repulsive forces

Double-diffused MOS transistors
IEEE Transactions on Electron Devices, 1967N-channel enhancement mode, MOS transistors with non-uniform substrate doping built on silicon and on thin films of silicon on sapphire are described. The non-uniform substrate doping is the result of additional boron doping limited to a portion of the channel length.

Double Auction on Diffusion Network
Proceedings of the AAAI Conference on Artificial IntelligenceMechanism design on social networks has attracted extensive attention recently. The goal is to design mechanisms to incentivize participants to invite more participants via their social networks, and the challenge is that the participants are competitors.

DIFFUSION WITH MIGRATION IN THE DIFFUSE DOUBLE LAYER
Canadian Journal of Chemistry, 1963The polarization characteristics of the concentration of the reactive species are discussed when the effects of migration in the diffuse layer are accounted for. A limiting case (ξ0 → ∞) and some particular cases (|Zi/Z| = 0, 1, 2, 3, 4) are derived both for attraction and repulsion in the double layer. Linear approximations (and conditions sufficient

Double-diffusive convection is the accurate but perhaps awkward name given to convective motions that occur in a fluid when the background density gradient is stably stratified.

In this chapter we turn our attention to processes of combined (simultaneous) heat and mass transfer that are driven by buoyancy. The density gradients that provide the driving buoyancy force are induced by the combined effects of temperature and species concentration nonuniformities present in the fluid saturated medium.

Within a statically stable fluid stratified by gradients of two or more properties with different molecular diffusivities (i.e. heat-salt, salt-sugar, etc.) turbulence and convective transports may take place without energy supply from the outside. In such a system a number of surprising phenomena may be observed depending on the relative gradients of ...

Double-diffusive magnetoconvection
Pramana, 1986This review deals principally with the interaction between double-diffusive convection and an externally imposed vertical magnetic field in a Boussinesq fluid. Both linear and nonlinear (two and three-dimensional) theories have been discussed. Double-diffusive magnetoconvection is shown to exhibit a rich variety of dynamical behaviour unimaginable in a

Double Diffusion in Oceanography
Annual Review of Fluid Mechanics, 1994The modern study of double-diffusive convection began with Melvin Stern's article on "The Salt Fountain and Thermohaline Convection" in 1960. In that paper, he showed how opposing stratifications of two component species could drive convection if their diffusivities differed.

Fully developed two-dimensional salt-finger convection is characterized by the appearance of coherent dipolar eddies which carry relatively fresh and cold fluid upward and salty and warm fluid downward. Such structures – the double-diffusive modons – are prevalent in the regime in which density stratification is close to neutral and the salt-finger ...
