Nano particles have a wide range of applications such as electronics, catalysis, chemistry energy and medicine and have thus gained commercial acceptance [1]. Besides improving their functionality, the use of nano technology can result in the production of textiles with completely novel properties or the combination of various functions [2]. Such multifunctional textiles include antistatic text...
The objective of this research was to develop a more sustainable composite and still keep its characteristics. Fibers treated with NaOH at 5% w/w for 2 hours were incorporated into natural rubber in different proportions (0 phr, 24 36 48 phr 60 phr). mechanical properties the composites suffered changes, increasing hardness, young’s modulus decreasing tensile strength. All physical not statisti...
Nanoscience and nanotechnology are considered to be the key technologies for the current century. Efforts are being made worldwide to create smart and intelligent textiles by incorporating various nanoparticles or creating nanostructured surfaces and nanofibres which lead to unprecedented level of textile performance, such as stain resistant, self-cleaning, antistatic, UV protective, etc. Howev...
The objective of this research is to study antibacterial and antistatic properties polyamide yarn which coated silver nanoparticles carboxymethylstarch (CMS). Silver were synthesized by a green synthesis method onto (PA) fibers. presence nanosilver yarns was confirmed scanning electron microscope (SEM), UV–visible spectra (UV-Vis) X-ray diffraction (XRD) techniques. concentration deposited on t...
مزایای عامل متحرک به اندازه ای است که در دنیای کنونی اجتناب از آن گریز ناپذیر است . اصلی ترین مانع در استفاده وسیع از عامل متحرک امنیت آنها می باشد . در جهت رفع این مشکل هر کدام از سیستمهای پیاده سازی شده موجود مثل agent tcl,tocama,concordia,voyager,aglets هر کدام به نحوی به مسئله امنیت پرداخته اند، ولی در اکثر سیستمها بعد امنیتی مدنظر نبوده و ناقص عمل می نمایند. مدل طراحی شده در این تحقیق ...
Radiologists make their main analysis and diagnosis based on careful observation of medical images, although there are all kinds of automatic methods under development. Radiologists typically use a scroll mouse to click on an image when they find something interesting, and they also use the mouse to navigate through the image slices in volumetric scans. Thus they perform many thousands of mouse...
The Kings Bay, Crystal River complex, located in Citrus County, Florida, is one of the world’s largest spring-fed ecosystems and a critical warm-water refuge for endangered Florida manatees. Unfortunately, large areas of Kings Bay are currently in a state of ecological degradation characterized by smothering mats of the filamentous cyanobacterium Lyngbya wollei. The causes of this ecosystem shi...
