On supercritical branching processes with emigration
Journal of Applied Probability, 2022 AbstractWe study supercritical branching processes under the influence of an independent and identically distributed (i.i.d.) emigration component. We provide conditions under which the lifetime of the process is finite or has a finite expectation.

Carbon and Hydrogen, EarlyView.This review systematically summarizes research progress on bismuth‐based semiconductor photocatalytic materials in the field of CO2 reduction. It focuses on elucidating the mechanisms by which four modification strategies—including heteroatom doping, oxygen vacancy engineering, microstructural control, and heterostructure fabrication—regulate band ...

Coupling Atomic Confinement With CO2 Pressure for Selective and Stable CO2 Electroreduction
Carbon Energy, EarlyView.The coupling of high‐pressure operation with atomic‐scale catalyst design was investigated via an electrochemical cation implantation (ECI) process to create confined reaction environments over SnOx catalyst. The synergistic interplay between structural confinement and CO2 pressure was investigated, and the reaction mechanism for CO2RR to CO was ...

Global and Detailed Calculation of Tube Wall Temperature in a Process Furnace Steam Superheater
Chemie Ingenieur Technik, EarlyView.This study presents a comparison between an iterative global model and multiple approaches to a new non‐iterative model with the purpose of predicting tube wall temperature of a superheater. The results show that the non‐iterative method achieves sufficient accuracy while improving the prediction of local temperature distribution and better ...

The Canadian Journal of Chemical Engineering, EarlyView.Abstract On the centennial of higher education in Chemical Engineering in Mexico, it is pertinent to revisit the key stages that have contributed to its consolidation as a vital discipline for the nation's scientific and technological advancement. Although the initial mission of chemical engineering education was primarily oriented toward the training ...

Caffeine Solubility In Supercritical Carbon Dioxide/co-solvent Mixtures
, 2015 In order to assess the effect of co-solvents on the solubility of caffeine in supercritical carbon dioxide, experimental solubility of caffeine in supercritical ethanol-carbon dioxide and isopropanol-carbon dioxide mixed solvents was obtained using a ...
