Evaluating the thermodynamic potential for carbon capture from internal combustion engines

open access: yesTransportation Engineering, 2022
This work explores the potential for use of carbon dioxide separation processes, colloquially known as carbon capture, to accelerate decarbonization of the transport sector.

Data-based fault detection in chemical processes: Managing records with operator intervention and uncertain labels [PDF]

open access: yes, 2016
Developing data-driven fault detection systems for chemical plants requires managing uncertain data labels and dynamic attributes due to operator-process interactions.

Towards the phase diagram of cold and dense heavy QCD [PDF]

open access: yesarXiv, 2022
The thermodynamics of QCD with sufficiently heavy dynamical quarks can be described by a three-dimensional Polyakov loop effective theory, obtained after a truncated character and hopping expansion. We investigate the resulting phase diagram for low temperatures by mean field methods.

Hitting times for independent random walks on $\mathbb{Z}^d$ [PDF]

open access: yesAnnals of Probability 2006, Vol. 34, No. 4, 1296-1338, 2004
We consider a system of asymmetric independent random walks on $\mathbb{Z}^d$, denoted by $\{\eta_t,t\in{\mathbb{R}}\}$, stationary under the product Poisson measure $\nu_{\rho}$ of marginal density $\rho>0$. We fix a pattern $\mathcal{A}$, an increasing local event, and denote by $\tau$ the hitting time of $\mathcal{A}$.

Spin Transport at Interfaces with Spin-Orbit Coupling: Phenomenology [PDF]

open access: yesPhys. Rev. B 94, 104420 (2016), 2016
This paper presents the boundary conditions needed for drift-diffusion models to treat interfaces with spin-orbit coupling. Using these boundary conditions for heavy metal/ferromagnet bilayers, solutions of the drift-diffusion equations agree with solutions of the spin-dependent Boltzmann equation and allow for a much simpler interpretation of the ...

Kinetics of Carbon Dioxide with tertiary Amines in aqueous solution [PDF]

open access: yes, 1999
The reaction of CO2 with TEA, DMMEA, and DEMEA has been studied at 293, 303, 318 and 333 K. All the kinetic experiments were carried out in a stirred cell reactor operated with a flat, smooth and horizontal gas-liquid interface. A numerical method, which

Variable coordination of amine functionalised N-heterocyclic carbene ligands to Ru, Rh and Rr: C-H and N-H activation and catalytic transfer hydrogenation [PDF]

open access: yes, 2011
Chelating amine and amido complexes of late transition metals are highly valuable bifunctional catalysts in organic synthesis, but complexes of bidentate amine–NHC and amido–NHC ligands are scarce.

Alternative approach to the critical behavior and microscopic structure of the power-Maxwell black holes [PDF]

open access: yes, 2019
Employing a new approach toward thermodynamic phase space, we investigate the phase transition, critical behavior and microscopic structure of higher dimensional black holes in an Anti-de Sitter (AdS) background and in the presence of Power-Maxwell field.

Machine Guided Discovery of Novel Carbon Capture Solvents [PDF]

open access: yesarXiv, 2023
The increasing importance of carbon capture technologies for deployment in remediating CO2 emissions, and thus the necessity to improve capture materials to allow scalability and efficiency, faces the challenge of materials development, which can require substantial costs and time.

Effect of hydrogen sulfide concentration in circulated amine solution on the treated gas in gas treatment plant

open access: yesJournal of Research in Environmental Science and Toxicology, 2018
The concentration of dissolved hydrogen sulfide in circulated amine is necessary to be determined and calculated that useful to make a relationship with hydrogen sulfide in the treated gas after passing through the sweetening process in order to help to control the regeneration process when the research is containing the control system to improve the ...
