Tekstil boyama endüstrisinde kullanılan Bazik Mavi 3 boyarmaddesinin alüminyum elektrot kullanılarak elektrokimyasal olarak tekstil atık sularından giderimi üzerinde çalışılmıştır. Kesikli proses ile yapılan deneyler sonrasında 10 dakika sonunda pH8 değerinde %97’den fazla giderim etkinliği hesaplanmıştır. Elektrokimy…
In this work, heavy metal oxide glasses based on Bi2O3–GeO2–Ga2O3–Na2O system have been synthesized under a low vacuum conditions. This procedure reduced absorption band at 3 μm due to OH- ions concentration decrease to 50 ppm. Glass has been characterized by low phonon energy (724 cm-1), low absorption coefficient in…
This work is devoted to studying the dielectric/metal multilayer planar waveguide structure that is composed of a highrefractive index, single mode, silica-titania film deposited on a BK7 glass substrate. The waveguide film is loaded with a thin gold film, through a thin silica film. It is assumed that a semi-infiniti…
The paper presents the principle of operation of the broad-band difference interferometer in the bimodal waveguide. In the planar bimodal waveguide modes fundamental TE0 and TE1 can be excited for the entire range visible light. During the propagation the difference of the phases between the modes is determined, which…
Synthetic polymers are increasingly used in medical practice. Modification of polymers with biologically active substances, which can stimulate regenerative processes, is an urgent task. Conjugation of folic acid to ferrocene is resulted in a new compound, which may combine biological activity of folic acid and immune…
The study detected the influence of copper iodide particles (CuI) in an aqueous suspension of yeast cells of Saccharomyces cerevisiae on intensifying the process of fermentation under conditions of endogenous metabolism by the method of differential microcalorimetry. The power of heat release suspensions was recorded…
The receptor for activated C kinase (RACK) is an important scaffold protein with regulatory functions in cells. However, its role in the immune response of Antheraea pernyi to pathogen challenge remains unclear. To investigate the biological functions of RACK in the wild silkworm A. pernyi, cloning was performed and t…
In this article there have been presented the use of boron-doped diamond films for sensor applications. The low-finesse Fabry-Pérot interferometer working in the reflective mode has been implemented. Two kinds of reflective layers have been elaborated: boron-doped diamond thin films and zinc-oxide (ZnO) layer. Thin Zn…
We employed a multitechnique approach using piezo-force response microscopy and photoemission microscopy to investigate a self-organizing polarization domain pattern in PbTiO3/La0.7Sr0.3MnO3 (PTO/LSMO) nanostructures. The polarization is correlated with the nanostructure morphology as well as with the thickness and Mn…
The ideal coating structure, which can achieve both high corrosion resistance and high conductivity, was examined by SEM analysis of conventional chromate-free coated steel sheets. Based on the results of SEM analysis, it was found that high conductivity was achieved by maintaining the convex parts of zinc plating cry…
Density waves are characteristic for fluidized beds and affect measurements on liquidlike dynamics in fluidized granular media. Here the intensity autocorrelation function as obtainable with diffusing-wave spectroscopy is derived in the presence of density waves. The predictions by the derived form of the intensity au…
Management of burn injury is an onerous clinical task since it requires continuous monitoring and extensive usage of specialized facilities. Despite rapid improvizations and investments in burn management, >30% of victims hospitalized each year face severe morbidity and mortality. Excessive loss of body fluids, accumu…
Graphene have attracted considerable attention in synthesis and electrochemical applications. In the present study, graphene paste electrode (GPE) was used to study electrochemical behavior of D-Cycloserine (DCS) using cyclic (CV), staircase (SCV) and square wave (SWV) voltammetric techniques. The electrochemical sens…
Degradation study reported on bromhexine hydrochloride is very rare, in this article smart degradation study based on first step neutralization process have been developed for analysis of bromhexine hydrochloride in the presence of its oxidative degradation product. These methods are two chromatographic method (HPLC,…
Simple, cost-effective, safe, accurate, precise and environmentally friendly spectro-photometric methods were developed and validated for the quantitative determination of valaciclovir (VAL) in the presence of its related impurity in bulk powder and in its pharmaceutical preparation. This related impurity namely guani…
Since the early 1990s nanofibers, particularly those of a carbonaceous content [1] have received heightened interest due to their advantageous physico-chemical characteristics (e.g., high strength, stiffness, semi-conductor, increased thermal conductivity and one of the highest Young’s modulus [2]).[...]
A method is demonstrated to monitor macroscopic translational diffusion using electron paramagnetic resonance (EPR) imaging. A host-guest system with nitroxide spin probe 3-(2-Iodoacetamido)-2,2,5,5-tetramethyl-1-pyrrolidinyloxy (IPSL) as a guest inside the periodic mesoporous organosilica (PMO) aerogel UKON1-GEL as a…
Piperidin, heterosiklik moleküller arasında en iyi bilinen yapılardan biridir. Güncel çalışmalar bu tür bileşiklerin yapı-doğrusal olmayan optiksel performans ilişkisine odaklanmaktadır. Doğrusal olmayan optik malzemelerin fiber optik iletişim ve optik sinyal işlemlerinde hayati öneme sahip oldukları bilinmektedir. Bu…
The role of the inversion layer on injection and recombination phenomena in light emitting diodes (LEDs) is here studied on a multilayer (ML) structure of silicon nanocrystals (Si-NCs) embedded in SiO2. Two Si-NC LEDs, which are similar for the active material but different in the fabrication process, elucidate the ro…
Molecular dynamics simulations based on an empirical potential were performed to study the interaction of graphene nanoribbons and the single-walled carbon nanotubes.
