Reactivity as one of the criteria for the selection of raw materials for the production of active fine mineral powders [PDF]

open access: yesНанотехнологии в строительстве, 2023
: Introduction. The simplest and most common method of obtaining fine mineral powder is mechanical dispersion. In the process of grinding the material went through some work (energy), which is spent on the formation of a new surface. Therefore, it is

Study of the structure and development of the set of reference materials of composition and structure of heat resisting nickel and intermetallic alloys

open access: yesСтандартные образцы, 2017
Relevance of research: There are two sizes (several microns and nanodimensional) of strengthening j'-phase in single-crystal heat resisting nickel and intermetallic alloys, used for making blades of modern gas turbine engines (GTD). For in-depth study of

Lattice methods for strongly interacting many-body systems [PDF]

open access: yes, 2013
Lattice field theory methods, usually associated with non-perturbative studies of quantum chromodynamics, are becoming increasingly common in the calculation of ground-state and thermal properties of strongly interacting non-relativistic few- and many ...

Lattice Field Theory Methods in Modern Biophysics [PDF]

open access: yes, 2006
An effective field theory exists describing a very large class of biophysically interesting Coulomb gas systems: the lowest order (mean-field) version of this theory takes the form of a generalized Poisson-Boltzmann theory.

Simulating fluid flows in micro and nano devices : the challenge of non-equilibrium behaviour [PDF]

open access: yes, 2009
We review some recent developments in the modelling of non-equilibrium (rarefied) gas flows at the micro- and nano-scale, concentrating on two different but promising approaches: extended hydrodynamic models, and lattice Boltzmann methods.

Quantum trajectories and open many-body quantum systems [PDF]

open access: yes, 2014
The study of open quantum systems has become increasingly important in the past years, as the ability to control quantum coherence on a single particle level has been developed in a wide variety of physical systems.

Nuclear Matter on a Lattice [PDF]

open access: yes, 1999
We investigate nuclear matter on a cubic lattice. An exact thermal formalism is applied to nucleons with a Hamiltonian that accommodates on-site and next-neighbor parts of the central, spin- and isospin-exchange interactions.

Lattice Boltzmann Magnetohydrodynamics

open access: yes, 1994
Lattice gas and lattice Boltzmann methods are recently developed numerical schemes for simulating a variety of physical systems. In this paper a new lattice Boltzmann model for modeling two-dimensional incompressible magnetohydrodynamics (MHD) is ...

Direct simulation of liquid-gas-solid flow with a free surface lattice Boltzmann method [PDF]

open access: yes, 2017
Direct numerical simulation of liquid-gas-solid flows is uncommon due to the considerable computational cost. As the grid spacing is determined by the smallest involved length scale, large grid sizes become necessary -- in particular if the bubble ...

Time-dependent currents of 1D bosons in an optical lattice

open access: yes, 2010
We analyse the time-dependence of currents in a 1D Bose gas in an optical lattice. For a 1D system, the stability of currents induced by accelerating the lattice exhibits a broad crossover as a function of the magnitude of the acceleration, and the ...
