Study on Natural Gas Decarbonization Process Based on CO2 Desublimation Characteristics

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Natural gas decarbonization is a crucial processing step. In this study, the snow separation technology for removal of carbon dioxide in natural gas based on CO2 desublimation characteristics was introduced. The phase equilibrium calculation of CH4‐CO2 and N2‐CO2 system was carried out by using cubic equations of states (EOSs), and identified ...

Cold dilute neutron matter on the lattice I: Lattice virial coefficients and large scattering lengths

, 2005
We study cold dilute neutron matter on the lattice using an effective field theory. We work in the unitary limit in which the scattering length is much larger than the interparticle spacing. In this paper we focus on the equation of state at temperatures

A Novel Green Method for Producing Medical‐Grade Chitosan From Loligo plei Squid Pens

Journal of Applied Polymer Science, EarlyView.
This work demonstrates a sustainable and simplified process for the production of medical‐grade chitosan from the feathers of the squid Loligo plei, employing mild chemical treatments to preserve the integrity of the polymer while achieving high purity and performance.

Statistical Mechanics of an Ideal Gas of Non-Abelian Anyons

, 2013
We study the thermodynamical properties of an ideal gas of non-Abelian Chern-Simons particles and we compute the second virial coefficient, considering the effect of general soft-core boundary conditions for the two-body wavefunction at zero distance ...

Structural Properties of Yukawa One‐Component Plasmas Revisited

Contributions to Plasma Physics, EarlyView.
ABSTRACTYukawa one‐component plasmas are fully described in terms of the Coulomb coupling parameter Γ$$ \Gamma $$ and the screening parameter κ$$ \kappa $$. One of their remarkable properties is the existence of lines of constant effective coupling, Γeff(Γ,κ)$$ {\Gamma}_{\mathrm{eff}}\left(\Gamma, \kappa \right) $$, along which their short‐range ...

The Virial Expansion of the Hydrogen Equation of State in Comparison to PIMC Simulations: The Quasiparticle Concept, IPD, and Ionization Degree

Contributions to Plasma Physics, EarlyView.
ABSTRACT The properties of plasmas in the low‐density limit are described by virial expansions. Analytical expressions are known for the lowest virial coefficients from Green's function approaches. Recently, accurate path‐integral Monte Carlo (PIMC) simulations were performed for the hydrogen plasma at low densities by Filinov and Bonitz (Phys. Rev.

The Virial Equation of State of Low-Density Neutron Matter

, 2005
We present a model-independent description of low-density neutron matter based on the virial expansion. The virial equation of state provides a benchmark for all nuclear equations of state at densities and temperatures where the interparticle separation ...

Determination of chain conformation of polysaccharides using a SEC‐MALLS‐Vis

Food Biomacromolecules, EarlyView.
Abstract For polysaccharides, biological activity is associated with the chemical structure as well as the chain conformation. The chain conformation is conventionally derived from the scaling relationships between weight‐average molecular weight (Mw) and intrinsic viscosity ([η]) or the radius of gyration (Rg) or the translational diffusion ...
