Free Radical Addition Polymerization Kinetics without Steady-State Approximations: A Numerical Analysis for the Polymer, Physical, or Advanced Organic Chemistry Course

Journal of Chemical Education, 2014
A numerical analysis of the free radical addition polymerization system is described that provides those teaching polymer, physical, or advanced organic chemistry courses the opportunity to introduce students to numerical methods in the context of a simple but mathematically stiff chemical kinetic system.

Integrated Production Chemistry Management Of The Schoonebeek Heavy Oil Redevelopment in the Netherlands: From Project to Start-Up and Steady State Production

SPE Heavy Oil Conference Canada, 2012
Abstract This paper describes the production chemistry management process undertaken during the design, commissioning and start-up phases of the Schoonebeek redevelopment. Challenging separation issues, saline water, together with a multitude of other process conditions, resulted in complex, but robust application portfolio.

Applications of non‐steady‐state kinetics in physical organic chemistry: guidelines for the resolution of the kinetics of complex reaction mechanisms

Journal of Physical Organic Chemistry, 2001
AbstractThe resolution of the kinetics of the reversible consecutive second‐order reaction mechanism involving the formation of a kinetically significant intermediate, which does not reach steady state before late in the first half‐life, followed by an irreversible product‐forming reaction is discussed. It is shown that an apparent second‐order rate

A coupled one‐dimensional radiative‐convective, chemistry‐transport model of the atmosphere: 1. Model structure and steady state perturbation calculations

Journal of Geophysical Research: Atmospheres, 1985
An atmosphere model composed of a narrow band radiative‐convective (RC) code coupled with a one‐dimensional chemistry and transport code is described. The RC model, formulated in log‐pressure coordinates, includes accurate solar absorption calculations for O3, O2, H2O, and CO2.

Cellular titration of apoptosis with steady state concentrations of H2O2: submicromolar levels of H2O2 induce apoptosis through fenton chemistry independent of the cellular thiol state

Free Radical Biology and Medicine, 2001
Apoptosis was studied under conditions that mimic the steady state of H(2)O(2) in vivo. This is at variance with previous studies involving a bolus addition of H(2)O(2), a procedure that disrupts the cellular homeostasis. The results allowed us to define three phases for H(2)O(2)-induced apoptosis in Jurkat T-cells with reference to cytosolic steady ...

Critical loads of acidity for surface waters in south-central Ontario, Canada: regional application of the Steady-State Water Chemistry (SSWC) model

Canadian Journal of Fisheries and Aquatic Sciences, 2002
Critical loads of acidity and the amount by which these critical loads are exceeded by atmospheric deposition (termed "exceedances") were estimated for 1469 lakes from five regions in south-central Ontario, Canada, using single lake chemistry measurements and sulphur deposition data for the period 1976–1999.

Chemical reduction of sulphur dioxide to free sulphur with lignite and coal. 1. Steady-state reaction chemistry and interaction of volatile components

Fuel, 1980
Abstract The chemical reduction of SO2 with North Dakota lignite has been discovered to be a facile reaction which occurs at a relatively low temperature of 600–650 °C. Under optimum conditions, the reaction chemistry can be controlled to allow 85–90% conversion of SO2 to free sulphur in a single-stage reaction.

Building a Steady Foundation through Equilibrium: Solution and Solid State Chemistry

Journal of Chemical Education, 2021
We have developed a new foundation-level course at our institution that links the concept of chemical equilibria from four of the traditional subdisciplines (analytical, biochemistry, inorganic, and physical). The course, entitled Solution and Solid State Chemistry (CHEM 210), is designed to serve our chemistry and biochemistry majors, as well as those

Exploring the chemistry behind protein-glycosaminoglycan conjugate: A steady-state and kinetic spectroscopy based approach

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2020
The impact of glycosaminoglycan (chondroitin sulphate, CS) on bone morphogenetic protein - 2 (BMP - 2) structure, stability (thermal and chemical), association kinetics and conformation was monitored by multiple spectroscopic techniques (UV-Visible, fluorescence and circular dichroism). The absorbance in peptide region and fluorescence intensity of BMP
