Nanodiamond (ND), an emerging new carbon material, was exploited to reinforce nylon 6,6 (PA66) polymer composites. Surface modified nanodiamonds with acyl chloride end groups were employed to chemically graft into PA66, enhancing the interfacial adhesion and thus the mechanical properties. The ND grafted PA66 (PA66-g-ND) reinforced PA66 composite prepared by in situ reactive extrusion exhibited...

this study was conducted to investigate the effect of biological treatment withpleurotus floridafungi on chemical composition and rumen dry matter (dm) and organic matter (om) degradability of wheat and barley straw. wheat and barley straw were collected from golestan province of iran and after pasteurization mixed with fungi spawn (than 5% by weight). after 21 days samples were dried in oven (...

We studied the interaction of human neutrophils with nylon wool in vitro and during filtration Ieukapheresis (FL) to better understand cellular events detrimental to neutrophils that occur during FL. When neutrophils purified from blood by gradient centrifugation and sedimentation were incubated with nylon wool in vitro, release of lysozyme from the cells occurred rapidly and to a degree that w...

background: regardless of numerous advances in surgical techniques, selection of the best technique to sew up wounds and the best suture material are still controversial. several postoperative complications, including wound infection, stitched wound, chronic incision pain, wound dehiscence and hernia stitches result from many factors such as used suture material. objectives: the aim of the pres...

In this research, fire and radiant heat protection and thermal comfort properties of cotton/nylon-Kermel blended woven fabrics, were utilized to predict the thermal comfort and protection limit of this fabric structure based on Woo and Barker developed model. The results showed that the porosity, the air permeability and the thermal resistance increased with Kermel fiber blend ratio. Conversely...

Aim of the Study: This study aims to evaluate cytotoxicity different stereolithographic 3D printed materials and polyetheretherketone for varying time intervals using MTT assay by application these intra-oral usage. Materials Methods: Three groups disc specimens (5 mm diameter, 2 thick) were manufactured either selective laser melting (PA6 nylon, fiber reinforced PA6 nylon) or milling (PEEK). T...

Background: Non-absorbable materials (nylon) are always used in cinch sutures to maintain nasal width and improve harmonious facial symmetry orthognathic surgery. However, a few drawbacks of nylon have been clinically reported following surgery, such as irritation exposure the sutures. An absorbable material (PDS) has proposed sutures, not only avoid complications but also stabilize for long-te...

Three groups of patients who had undergone cataract extraction through a corneal incision closed with 10/0 nylon sutures one, two, and three years previously were recalled to determine the incidence of suture related complications. Broken corneal sutures were found in 87.5% of patients after two years and 90% after three years and were causing symptoms in over half the patients. It is recommend...
