The polyester (100%), cotton (100%) and Polyester / Cotton blend fabrics (65 / 35; 50 / 50 & 35 / 65) were treated with sodium hydroxide followed by hydrophilic finishing and dyeing to impart hygroscopic and dyeing characteristics. Then the finished fabric was tested for k/s value, fastness properties, wetting behaviour, water retention, wicking behaviour and static charge respectively. The sod...

This paper investigated the moisture absorption, mechanical behavior and the dielectric performance of hybrid and non-hybrid polymeric composites. Hand lay-up technique was used for processing carbon; glass reinforced polyester resin composites (non-hybrid) and carbon-glass/polyester hybrid composites with various fiber configurations. The maximum resistance of water absorption was obtained for...

We report on synthesis of two highly disperse nanoparticles viz. Fe2O3 & f-Fe2O3 using chemical reduction method. Reaction was initiated to mix solution A (i.e. Fecl3 6H2o) into solution B (i.e. Fecl24H2o) together under the presence of ammonium to develop nanoparticles. Mechanical properties of above mentioned nanoparticles filled with polyester polymer nanocomposites were fabricated to assess...

In the present investigation, we successfully fabricate a hybrid polymer nanocomposite containing epoxy/polyester blend resin and graphene nanoplatelets (GNPs) by a novel technique. A high intensity ultrasonicator is used to obtain a homogeneous mixture of epoxy/polyester resin and graphene nanoplatelets. This mixture is then mixed with a hardener using a high-speed mechanical stirrer. The trap...

Excellent mechanical properties of carbon nanotubes (CNTs) make them outstanding candidate reinforcements to enhance mechanical properties of conventional composites. The glass/polyester composites are widely used in many industries and applications. Improving the mechanical properties of such composites with addition of CNTs can increase their applications. In this research, multi-walled carbo...

BACKGROUND Despite efforts to improve surgical techniques, serious complications still sometimes occur. Use of a physiological posterior mediastinal pathway has increased given advances such as automated anastomotic devices and a reduction in the incidence of anastomotic sufficiency. Until now the gastric conduit created has been protected by an echo probe cover and, sown to the ventral side of...

Self-metathesis of undecenoic acid with [(PCy3)2Cl2Ru=CHPh] (2), followed by exhaustive hydrogenation yielded pure 1,20-eicosanedioic acid (5) (>99%) free of side-products from isomerization. Polycondensation with eicosane-1,20-diol (6), formed by reduction of the diol, yielded polyester 20,20 (Tm = 108 °C). By comparison, the known ADMET polymerization of undec-10-enyl undec-10-enoate (7), and...

We read with interest the paper by Lee et al. [1]. They reported that continuous exposure to an electromagnetic field with extremely low frequency may induce testicular germ cell apoptosis in mice. Our group performed a series of experiments on the effect of exposure to an electrostatic field on spermatogenesis and sexual activity [2–7]. Polyester (polyethylene terphthalate) exhibited electrost...
