From Greenhouse Gas to 3-D Surface-Microporous Graphene（图）
Greenhouse Gas 3-D Surface Microporous Graphene
2017/9/1
A material scientist at Michigan Technological University invented a novel approach to take carbon dioxide and turn it into 3-D graphene with micropores across its surface. The process is the focus of...
Distribution of the Riemann zeros represented by the Fermi gas
Distribution the Riemann zeros represented Fermi gas
2010/11/8
The multiparticle density matrices for degenerate, ideal Fermi gas system in any dimension are calculated. The results are expressed as a determinant form, in which a correlation kernel plays a vital ...
Many-body spin interactions and the ground state of a dense Rydberg lattice gas
Many-body spin interactions ground state dense Rydberg lattice gas
2010/11/11
We study a one-dimensional atomic lattice gas in which Rydberg atoms are excited by a laser and whose external dynamics is frozen. We identify a parameter regime in which the Hamiltonian is well-appr...
One Dimensional Magnetized TG Gas Properties in an External Magnetic Field
TG Gas External Magnetic Field potential energy
2010/3/10
With Girardeau's Fermi-Bose mapping, we have constructed the eigenstates of a TG gas in an external magnetic field. When the number of bosons $N$ is commensurate with the number of potential cycles $M...
Simultaneously Finite Size and Interaction Effects on a Harmonically Trapped 87Rb Gas
Bose-Einstein condensation finite size and interaction effects density of states approach
2010/4/9
In the framework of the semiclassical approximation (KB T >> \hbarW), an accurate ansatz formula for the density of states is suggested. This formula is able to include the finite size, interatomic in...
Hydrodynamic Model for the Plasma-Gas Flow in a Cutting Torch Nozzle
Hydrodynamic Model the Plasma-Gas Flow a Cutting Torch Nozzle
2010/10/26
We present a simple hydrodynamic model to obtain the profiles of the relevant physical quantities along a nozzle of arbitrary cross-section in a cutting torch. The model uses a two-zone approximation ...
Fast Opening Gas Valve for the TCABR Pellet Injector
Fast Opening Gas Valve the TCABR Pellet Injector
2010/10/27
Fast acting gas valves that operate between two very different pressure environments, which may differ in several orders of magnitude, are not available commercially and, therefore, they must be speci...
Revisiting the First-Principles Approach to the Granular Gas Steady State
the First-Principles Approach the Granular Gas Steady State
2010/10/26
We extend a Fokker-Planck formalism, previously used to describe the behavior of a cooling granular gas, with a Hertzian contact potential and viscoelastic radial friction, giving a velocity dependent...
