Surface Modification of Polyester Fabrics by Ozone and its Effect on Coloration Using Disperse Dyes: A Recent Study| Chapter 3 | Research Aspects in Chemical and Materials Sciences Vol. 4

 In this work, we report on the use of gases forming the atmosphere gas to reduce the surface of polyester fibers, and the effect of this pre-treatment on the dyeing nature of these fibers using scatter dyes. Because of its high crystallinity, non-concerning ancient culture nature, and tide when water is lowest absorption, polyester fibers (PES) are the most usual textile fibers. The synthetic interactions between polyester, perfecting compounds, and dyes are particularly troublesome, nevertheless, because of their synthetic structure. We report on the use of gases forming the atmosphere to modify the surface of polyester fibers with the aim of improving the interplay of the modified surface with perfecting compounds and dyes. We used C.I. Disperse Yellow 211 to dye air-treated polyester structures and evaluated the effects of air treatment utilizing FTIR-ATR, Raman spectroscopy, SEM imaging, rubbing tests, and capillarity calculations. We evaluated the dyeing acting via color analysis and driven the dyeing kinetics. This work shows that upper layer of atmosphere treatment is a good way to weaken inputs in the dyeing processes and also wastewater situation expenses, thus, lowering the environmental impacts of the fabric industry as well as conceivably decreasing the handle costs.

Determination of Surface Modified CVD Diamond/ Si(111) Film Post Implanted Ion Fe-B and NiFe-B Related to Magnetoresistance Properties | Chapter 9 | Recent Trends in Chemical and Material Sciences Vol. 3

 STEM has been used to investigate the nanostructure of Fe-B and NiFe-B after implantation on CVD diamond/Si(111) films, as well as their Magnetoresistance(MR) phenomena. Two samples were extensively examined: the first is a post NiFe-B sample with an E=70keV and a dose of 1015 ions/cm2; the second sample is a pre-NiFe-B sample with an E=70keV and a dose of 1015 ions/cm (denoted as A-E3D1). Second, at E=20 keV and a dosage of 1015 ions/cm2, is post FeB. (denoted as B-E1D1). The MR ratio in A-E3D1 sample is around 80 percent, while the MR ratio in B-E1D1 sample is 45 percent, based on FPP measurements at room temperature (RT) and Happlied=8 kOe. According to STEM-EDX research, there are two reasons why the MR ratio of A-E3D1 is larger than that of B-E1D1. To begin with, the surface nanostructure on the top of the A-E3D1 film is more grazing than the top of the B-E1D1 film. The formation of an amorphous carbon layer on top of the implanted diamond film with a thickness of roughly 100 nm was detected using a scanning transmission electron microscope (STEM) equipped with Electron Energy Loss Spectroscopy (EELS). Boron atoms were detected in a uniform distribution inside the carbon amorphous layer. Second, the oxygen level at the diamond film-silicon substrate interface in sample A-E3D1 was lower than in sample B-E1D1. As a result of this condition, the resistance value in A-E3D1 is lower than in B-E1D1. This result is consistent with Raman Spectroscopy data, implying that changes in the Raman spectrum due to implantation are related to Oxygen excitation from the B-E1D1 sample and magnetic film characteristics, respectively.

Thermodynamic Description of Living Homeostasis | Chapter 10 |New Insights into Physical Science Vol. 1

We studied the homeostatic equilibrium of the healthy organism. The homeostasis is controlled by oppositely effective physiologic feedback signal-pairs in various time-scales. We show that the entropy of every signal in this state is identical and constant: SE=1.8. The controlling physiological signals fluctuate around their average values. The fluctuation is time-fractal, (pink-noise), which characterizes the homeostasis. The aging is the degradation of the competing pairs of signals, decreasing the complexity of the organism. This way, the color of the noise gradually changes to brown. A special scaling process occurs during the aging: the exponent of the frequency dependence of the power density function grows in this process from 1 to 2, but the homeostasis of the system is unchanged.

Surface Modification of Sulfide for QCM Based Protein Biosensor | Chapter 12 | New Insights into Physical Science Vol. 1

The rapid development of surface sensitive biosensor technologies requires optimum control of surface modification to provide reliable and reproducible results. To assemble a quartz crystal microbalance (QCM)-based protein biosensor, we focused our attention on the sulfide receptor and its integration with the surface of the golden electrode. Here, we present different surface modification processing time to allow sulfide molecules to be immobilized to a gold-coated sensor for QCM sensing. The surface modification was also tested with bovine serum albumin (BSA) binding measurement. The optimum surface modification processing time was obtained according to the experiment.
