Almost full recovery in output intensity red fiber cycles. sensitivities 0.07 nm/°C this fibers was revealed. In paper, we report temperature polymer optical dyes (red and orange). Specifically, have analyzed average wavelength spectra emitted by both wh...

Systematic designed experiments were employed to find the optimum conditions for extraction of direct, reactive, and vat dyes from cotton fibers prior to forensic characterization. Automated microextractions were coupled with measurements of extraction efficiencies on a microplate reader UV-visible spectrophotometer to enable rapid screening of extraction efficiency as a function of solvent com...

Designed experiments based on a simplex mixture design were employed to explore the effects of three solvent components (water, formic acid, and aqueous acetic acid), extraction time, and extraction temperature for the automated microextraction of basic (cationic) dyes from acrylic fibers. Extractions were conducted by an automated liquid handling system, and dye extraction was evaluated using ...

Fiber-optic chemical sensing has been demonstrated with a side-polished single-mode optical fiber, evanescently coupled to chemically sensitive Langmuir-Blodgett (LB) overlay waveguides. The sensors exhibit a channel-dropping response centered on a wavelength that is dependent on the thickness and the refractive index of the overlay waveguide. It has been shown that pH-sensitive organic dyes pr...

Introduction: Several new bifunctional reactive dyes of the Sumifix Supra range that carry monochlorotriazine and sulphato ethyl sulphone reactive systems were developed and their dyeing performance studied. Suitable characteristic properties and fastness properties were examined over the knitted cotton fabrics. The dyes were characterized by spectral data and elemental analysis. The dyes struc...

Kynol fibers are excellent flame-retardant materials used for manifold applications. These exhibit originally an orange coloration. Up to now, dyeing processes less reported, and the functionalization of these by finishing is investigated. With this background, main aim paper evaluation different fiber – a woven fabric non-woven material. The following types dyestuff evaluated direct dyes, vat ...

Activation and repolarization across mammalian hearts follow complex three-dimensional pathways that are governed by fiber structure, intercellular coupling, and action potentials (APs) with spatially heterogeneous properties. Voltage-sensitive dyes and imaging techniques offer new insights on how spatiotemporal heterogeneities of APs govern propagation, repolarization, and AV node conduction a...

Jute is one of the available and cheap cellulosic fibers that can be printed used instead other materials may relatively high in price. bio-degradable raw therefore does not cause harm to environment along with advantages because its many advantages, it called golden fiber. Textile printing practice applying color distinct patterns or designs sharp outlines. Inappropriately fibers, tied fiber, ...

A robust fluorescence correlation spectroscopy system called fiber-optic based (FB-FCS) was developed; this enables the measurement of diffusion dynamics and concentration fluorescent molecules on principle without any mechanical adjustment experimental setup. The consisted fiber optics a water-immersion objective lens. hydrodynamic diameters concentrations organic dyes fluorescently labeled pr...
