This article describes additional data related to a research article entitled "Kinetics of Quadruplex to Duplex Conversion" (Mendoza et al. 2015 [1]). We followed the opening reaction of a series of intramolecular G-quadruplex structures by the addition of their corresponding complementary strand. Fluorolabeled complementary strands allowed to monitor the reaction in real-time. An adapted kinet...

The kinetic identification of chemical reaction systems often represents a time-consuming and complex task. This contribution presents an approach that uses rate estimation and feedback linearization to implement effective control without the use of a kinetic model. The reaction rates are estimated by numerical differentiation of reaction variants that are computed from measurements. The approa...

The article is focused on the aspects of using micro-catalytic pulse reactors for studying gas-phase reactions. A literature review includes data regarding different types of micro-catalytic pulse reactor applications in heterogeneous catalysis and the techniques used for estimating kinetic parameters are summarized. The experimental part describes the adaptation of a pyrolysis chromatograph to...

kinetics of the chemical leaching of chalcocite from a low-grade copper ore in a ferric sulfate medium was investigated using the constrained least square optimization technique. the experiments were carried out for different particle sizes in both the reactor and column at constant eh, ph, and temperature. the leaching rate increased with increase in the temperature. about 50% of the cu recove...

This paper deals with the dynamic modeling of a hydrogen production system using gPROMS. The model includes mass balances, liquid-gas equilibrium relations, mass transfer laws and kinetic reaction equations. The initial reaction mixture is a sodium borohydride solution that reacts via a self-hydrolysis mechanism in the presence of water. The behavior of this system was measured in terms of prod...

run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
