The proband with lifelong hemolytic anemia has a high phosphoenolypyruvate (PEP) erythrocyte pyruvate kinase (PK) variant substantially but incompletely normalized by the allosteric modifier fructose-i .6-diphosphate (F-i ,6-P2) with conversion of sigmoidal to hyperbolic kinetics. Heterozygotes in four generations express qualitatively identical but less severely abnormal kinetics and lack over...

styrene nanocomposites were synthesized by in-situ atom transfer radical polymerization at 110oc. the variations of monomer conversion and the linearity of semilogarithmic kinetic plot, some signs of living polymerizationand constant radical concentration in the reaction medium, were revealed by gas chromatography technique (gc). according to the gel permeation chromatography (gpc) results, the...

This paper presents a hierarchical modeling approach for Solid-Oxide Fuel Cells from elementary kinetics to stacks. On a fundamental level, we have developed an analytical model for the evaluation of volume specific three-phase boundary length (vLtpb) in composite electrodes and electrochemical kinetics expressions to account for coverage dependent activation energies of various surface adsorbe...

The transformation of 3-chlorobenzoate (3CB) and acetate at initial concentrations in the wide range of 10 nM to 16 mM was studied in batch experiments with Pseudomonas sp. strain B13. Transformation rates of 3CB at millimolar concentrations could be described by Michaelis-Menten kinetics (K(infm), 0.13 mM; V(infmax), 24 nmol (middot) mg of protein(sup-1) (middot) min(sup-1)). Experiments with ...

Photo responsive polyethyl vinyl ketone (PEVK) and various block copolymers were prepared through the visible light induced cobalt mediated radical polymerization (CMRP) process. The first order kinetics and linear increase in molecular weight with conversion demonstrated a well-behaved system. Chain extension experiments showed the retention of the living end of PEVK.

γ-Mg(BH4)2 was found to be a promising material for CO2 recycling (mainly to formate and alkoxide-like compounds). CO2 conversion occurs with unprecedented fast kinetics at 30 °C and 1 bar. A multi-technique approach allowed to attribute the superior performance of γ-Mg(BH4)2 to its large specific surface area.

Conversion, selectivity, yield and kinetics of 1-hexanol liquid phase dehydrocondensation to di-n-hexyl ether (DNHE) were determined at 150-190 oC on the thermally stable resin Amberlyst 70 in a batch reactor. At 190oC, 1-hexanol conversion of about 71 %, with selectivity to ether of 87 % was obtained after 6-h reaction time. A kinetic model stemming from an Eley-Rideal mechanism in which 1-hex...

The time course of thermal reactions after illumination of 100% humidified bacteriorhodopsin films was followed with FTIR spectroscopy between 125 and 195 K. We monitored the conversion of the initial photoproduct, K, to the next, L intermediate, and a shunt reaction of the L state directly back to the initial BR state. Both reactions can be described by either multiexponential kinetics, which ...
