Returning corn cobs to the field during kernel harvesting is an effective way improve soil properties and increase crop yield. However, seasonally frozen seriously hinders decomposition process of cobs. To explore characteristics promote decomposition, in this study, nylon mesh bag method was used perform tests for 150 days. Fiber composition analysis microstructure observation were carried out...

Graphene is a single-atom-thick layer of carbon atoms, the thinnest material ever discovered. The special single atomic structure graphene makes it have many unique physical and chemical properties, these excellent properties make bright application prospect in field composite materials. use modern digital production technology to coordinate management various departments an enterprise can grea...

Two experiments were carried out to evaluate the effects of indigestible neutral detergent fiber (iNDF) of ration for estimation of rumen degradability of fiber in sheep. In experiment 1, to determine feed iNDF, four ruminal fistulated Zel ewes were used. Three grams of alfalfa hay, corn silage, barley grain, wheat bran, ration 1 (including alfalfa hay and concentrate), and ration 2 (including ...

the nylon and nylon/lycra yarns were coated with electrically conductive polymers such as polyaniline and polypyrrole, via chemical polymerization process. electrical conductivity of the coated yarns was measured at variousstrain levels using two-point probe technique and their strain sensitivities were studied. the results showed that, electrical conductivity of the coated yarns decreased with...

Preparation of silver nanoparticle by using leaf extracts of Terminalia catappa, its deposition on Nylon fabrics, and the modification with an addition of HDTMS have been conducted in this research. The samples prepared in this study were nylon cloth (N0), nylon cloth silver nanoparticles (N1), Nylon cloth HDTMS (N2), Nylon cloth − silver nanoparticles − HDTMS (N3), and Nylon cloth HDTMS silver...

This paper describes the effects of reinforcement by randomly distributed nylon fibers and addition of nanoclay on some engineering properties of a typical asphalt concrete. The properties of asphalt concrete reinforced by different percentages of 25 mm nylon fibers have been compared with those of the mixtures containing different percentages of nanoclay and those in which both the fibers and ...

Blends of nylon-6 with polybutadiene were prepared with comparable morphology and different molecular weights of the matrix. These specimens were tested using the notched Izod impact test and the notched tensile impact test. An increase in molecular weight resulted in a shift of the brittle-to-tough transition temperature of 40°C to lower temperatures. In the notched tensile impact tests, espec...

Abstract We checked the spatial pattern of debris stranding at Praia de Santos (Brazil) in first hour after peak high and low tide summer winter. recorded counted 20 types (natural anthropogenic) 6 transects arranged 3 zones along beach (deposition, transport, erosion). Canonical Correspondence Analysis (CCA) showed that buoyancy was an essential property distinguishing behaviours. The erosion ...

Fiber-reinforced 3D printing technology offers significant improvement in the mechanical properties of resulting composites relative to printed (3DP) polymer-based composites. However, 3DP fiber-reinforced composite structures suffer from low fiber content compared traditional composite, such as orthogonal woven preforms solidified with vacuum assisted resin transfer molding (VARTM) that impede...
