A high-resolution Raman mapping method has been developed in order to obtain 2D information about structural anisotropies (crystallinity, molecular alignment) thin filament cross-sections (diameters between 27 ?m and 79 ?m). Cross-sections of melt-spun, hot-drawn poly (ethylene terephthalate) (PET) filaments bicomponent core-sheath PET-polyamide 6 (PA6) have scanned through a laser beam (spatia...

Abstract Background Integrated whole-body PET/MR technology continues to mature and is now extensively used in clinical settings. However, due the special design architecture, integrated comes with a few inherent limitations. Firstly, lacks sensitivity resolution for focused organs. Secondly, broader access of has been significantly restricted its prohibitively high cost. The MR-compatible PET ...

BACKGROUND Measurement of coronary sinus blood flow (CSF) by phase-contrast magnetic resonance (PC-MR) imaging at rest and during hyperemia may allow noninvasive assessment of global coronary hemodynamics. METHODS AND RESULTS Sixteen healthy volunteers (age, 22 to 32 years) were examined with MR and PET in random order within 1 to 2 days. At rest and during hyperemia (dipyridamole 0.56 mg/kg)...

Escherichia coli (E. coli) was used to activate hydrolysis reaction along with biodegradation in natural and synthetic fibers to identify possibilities as alternative substitutes for textile wastes using chemical solutions and enzymes. To confirm the reaction between the bacterial infections of E. coli and the excessively abundant interstitial spaces of the fibers, various types of natural and ...

One of the main issues with Carbon Fiber Reinforced Thermoplastics (CFRTP) is poor impregnation quality matrix on carbon fiber due to high viscosity thermoplastic. Impregnation can significantly affect mechanical properties composite. This study aims compare abilities various types thermoplastic matrices fiber. The used in this are HDPE, PC, and PET. Three variations treatment were employed: fi...

The present research investigates the application of green method to produce nanocomposites. CuO/PET fiber nanocomposite can be prepared in two ways. first way involves electrospinning technique by which waste plastic cups polyethylene terephthalate (PET) are converted into nanofibers. In second way, copper nanoparticle (CuONPs) is synthesized with natural capped plant extract sumac (Rhus Coria...

Abstract This article presents the results of a study on laser ablation selected thermoplastic polymers using an economical fiber with scanning galvanometer system and IR wavelength λ = 1064 nm. The aimed to develop comparative characteristics processes commonly used constructional thermoplastics, namely acrylonitrile butadiene styrene terpolymer (ABS), polystyrene (PS), poly(ethylene terephtha...
