The three-dimensional structure of nylon hydrolase and the mechanism of nylon-6 hydrolysis*

Histopathologic and comparisons of the properties of skin,sutured withb and Iranian and a foreign brand nylon suture in rat

  This study was designed to elucidate the possible difference between supa and ethicon.nylon in suturing rat skin.75 female spragne-dawley albino rats with mean weight 250 g were used and randomly divided into three groups of 30,30 and 15 rats.in 60 rats anesthesea was induced by ketamin and xylazin.followed by surgical preparation , a 5 cm abdominal skin incision was made and sutured by simp...

A Study on the Kinetic and Thermodynamic Parameters of Different Acid Dyes on Nylon 6 Fibers

Nylon-9 from Unsaturated Fatty Derivatives: Preparation and Characterization

Methyl azelaaldehydate, soy nitriles, and oleonitrile were compared as starting materials for making nylon-9. Less difficulty was encountered in purifying intermediates from oleonitrile than from the other two. All 3 routes involved hydrolysis of methyl 9-aminononanoate to 9-aminononanoic acid. Self catalyzed hydrolysis of the amino ester in water produced low yields of monomer owing to oligome...

Detoxification of organophosphate pesticides using a nylon based immobilized phosphotriesterase from Pseudomonas diminuta.

A partially purified phophotriesterase was successfully immobilized onto nylon 6 and 66 membranes, nylon 11 powder, and nylon tubing. Up to 9000 U of enzyme activity was immobilized onto 2000 cm2 of a nylon 6 membrane where 1 U is the amount of enzyme necessary to catalyze the hydrolysis of 1.0 mumol of paraoxon/min at 25 degrees C. The nylon 66 membrane-bound phosphotriesterase was characteriz...

EXPERIMENTAL ANALYSIS OF CNC TURNING OF NYLON USING TAGUCHI METHOD

Manufacturing process frequently employs optimization of machining parameters in order to improve product quality as well as to enhance productivity. The material removal rate is a significant indicator of the productivity and cost efficiency of the process. Taguchi method has been implemented for assessing favorable (optimal) machining condition during the machining of nylon by considering thr...
