در قسمت اول کار تحقیقاتی حاضر، با استفاده از روش الکتروریسی به تولید نانوالیاف پلیمری nylon-66 و polyamide-6 پرداخته شده است. اثر پارامترهای موثر بر فرآیند الکتروریسی از قبیل غلظت محلول پلیمری، ولتاژ الکتروریسی، فاصله ی الکتروریسی و سرعت تزریق محلول بهینه شدند. همچنین اثر نمک بر فرآیند الکتروریسی مورد مطالعه قرار گرفت و مشاهده شد که در حضور نمک الیاف نازک تر با دانه های کمتر تولید شد. نانوالیاف...
Inter-organizational design processes are inefficiently supported by management tools w.r.t. to their dynamic nature and inherent complexity. In this paper, we present an innovative framework for the definition, analysis, improvement, and management of such design processes. Key features are to bridge the gap between modeling and execution of inter-organizational design processes and the seamle...
In this study, the influence of different weight percentages of glass fiber (GF) reinforcement on the mechanical properties of nylon (PA6) composite is investigated. Test specimens of pure nylon, 95% nylon + 5% GF, 90% nylon + 10% GF, 85% nylon + 15% GF and 80% nylon + 20% GF are prepared using an injection molding machine. In the experiments, tensile tests and impact tests are carried out. The...
BACKGROUND Nylon teeth myth is a belief of associating infant illnesses with bulges on infants' alveolus that mark the positions of underlying developing teeth and that it is necessary to treat the condition mainly by traditional healers to prevent infant death. The traditional treatment often leads to serious complications that may lead to infant death. Although the government instituted educa...
Peptides have the potential to serve as an alternative for petroleum-based polymers to support a sustainable society. However, they lack thermoplasticity, owing to their strong intermolecular interactions. In contrast, nylon is famous for its thermoplasticity and chemical resistance. Here, we synthesized peptides containing a nylon unit to modify their thermal properties by using papain-catalyz...
A nylon bar, with the head notched to make easy adequete contact with the short process of the malleus, was used for an acoustic probe. The first part of this paper deals with the acoustic properties of the nylon probe in comparison with those of a piano wire probe and a silver wire probe. The following results are obtained : (1) Clinically the most suitable length of the nylon probe was 8cm. (...
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...
