We have measured the radon di!usion, solubility and permeability coe$cients of various foils being of interest for the Borexino experiment. The applied methods and instrumentation are described and the mathematical model for di!usion of Rn, including its decay, is outlined. A very strong in#uence of water on the Rn di!usion through nylon foils was found. The rather low Rn permeability for dry n...

When the mycoparasitic, biocontrol fungus Trichoderma harzianum was allowed to grow on nylon fibers treated with concanavalin A or Sclerotium rolfsii lectin, it coiled around the nylon fibers and produced hooks in a pattern similar to that observed with the real host hyphae. The incidence of interaction between T. harzianum and S. rolfsii lectin-treated fibers was significantly higher than that...

To The Editor: To elucidate the mechanism of granulocyte damage during FL, studies have been reported of the interaction between nylon-wool fibers and isolated granulocytes suspended in protein free media,’2 in 5% plasma,2 or in 1% human serum albumin.3 In FL, however, heparinized whole blood is passed through a nylon-wool filter, resulting in plasma protein coating of the fibers within seconds...

A complete force field (MSXX) for simulation of all nylon polymers is derived from ab initio quantum calculations. Special emphasis is given to the accuracy of the hydrogen bond potential for the amide unit and the torsional potential between the peptide and alkane fragments. The MSXX force field was used to predict the structures, moduli, and detailed geometries of all nine nylons for which th...

We describe the use of a continuous-flow clinical analyzer with an immobilized coupled-enzyme nylon tube reactor and an immobilized single-enzyme nylon tube reactor for routine estimation of lactate and pyruvate in serum. These reactors are incorporated into the flow system of a modified continuous-flow analyzer (Technicon AutoAnalyzer). Results for serum lactate and pyruvate by this method are...

In this study the biodegradative activity of Pleurotus ostreatus was tested against a natural waste (Coir) along with a synthetic polymer waste (Nylon 6). Lignin modifying enzymes such as laccase, lignin peroxidase and manganese peroxidase activity were tested for coir and nylon 6 degradation in solid substrate fermentation. Enumeration of degradation with loss of weight, lignin degradation ass...

Silica nanoparticles (SiNPs) are a promising material for nanomedicine technology. SiNPs considered powerful tool drug delivery, functional coatings and films, biomolecule separation due to their stability, biocompatibility, accessible surface modification. Herein, the synthesis of nylon 6 (SiNPs-Nylon) coated nanocomposites was proposed. Transmission electron microscopy (TEM) dynamic light sca...
