Separation of Carbon Dioxide from Real Power Plant Flue Gases by Gas Permeation Using a Supported Ionic Liquid Membrane: An Investigation of Membrane Stability

open access: yesMembranes, 2019
The separation of carbon dioxide from coal-fired power plant flue gases using a CO2/N2-selective supported ionic liquid membrane (SILM) was investigated and the performance and stability of the membrane during operation are reported.

Splitting of inviscid fluxes for real gases [PDF]

open access: yes
Flux-vector and flux-difference splittings for the inviscid terms of the compressible flow equations are derived under the assumption of a general equation of state for a real gas in equilibrium.

Use of quantum quenches to probe the equilibrium current patterns of ultracold atoms in an optical lattice

open access: yes, 2012
Atomic bosons and fermions in an optical lattice can realize a variety of interesting condensed matter states that support equilibrium current patterns in the presence of synthetic magnetic fields or non-abelian gauge fields.

Primary Study of Woody Biomass and Coal for Energy Production Investigated by TGA-FTIR Analysis

open access: yesBioResources, 2015
The purpose of this study was to determine the pyrolysis characteristics and gas properties of woody biomass and coal. The main gases from the pyrolysis of biomass, coal, and mixtures of different ratios of the two were identified using TGA-FTIR.

Cusp Kernels for Velocity-Changing Collisions

open access: yes, 2012
We introduce an analytical kernel, the "cusp" kernel, to model the effects of velocity-changing collisions on optically pumped atoms in low-pressure buffer gases. Like the widely used Keilson-Storer kernel [J. Keilson and J. E. Storer, Q. Appl. Math. 10,

Shockwave overpressure of propellant gases around the mortar [PDF]

open access: yesScientific Technical Review, 2016
This paper is a result of many years of research in the field of the powder gases shockwave overpressure, which occurs during firing from the mortar. The cause of these occurrences is a sudden flow of powder gases from the weapon barrel and its expansion

Design and Simulation of Exhaust Pollution Monitoring Sensor Based on Photonic Crystal Fiber

open access: yesAl-Mustansiriyah Journal of Science, 2019
Many critical issues appear due to the exhaust gases from transportations facilities, electric generators, industries, and so on. This lead to air pollution, which could be define as an introduction of biological materials or chemicals that’s causes harm

Economics-Based Optimization of Unstable Flows

open access: yes, 1999
As an example for the optimization of unstable flows, we present an economics-based method for deciding the optimal rates at which vehicles are allowed to enter a highway.

Heat capacity of the generalized two-atom and many-atom gas in nonextensive statistics

open access: yes, 2009
We have used the generalized two-atom ideal gas model in Tsallis statistics for the statistical description of a real gas. By comparing the heat capacity with the experimental results for the two-atom molecule gases such as N2, O2 and CO, we find that ...

Experimental Study on the Changing Rules of Coal Fire Indictor Gases of the Whole Combustion Phases in Confined Space

open access: yesBrazilian Archives of Biology and Technology
When the coal mine fire occurs, it is crucial to judge the fire combustion state by analyzing indicator gases concentration and changing trends of various gas ratios in order to formulate proper rescue measures.
