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. The results indicated that a piece of graphene nanoribbon can form a tube structure inside or outside single-walled carbon nanotubes spontaneously under…
A spectrometric system was developed for spent fuel burnup evaluations at the LVR-15 research reactor, which employed highly enriched (36%) IRT-2M-type fuel. Such a system allows the measurement of fission product axial distribution by measuring certain nuclides, such as Cs137, Cs134, and their ratios, respectively. W…
A novel compound of zinc (II) ion, [ZnCl 2 (peta) 2 ] [peta: 4-Pyridinethioamide] was synthesized and characterized by XRD and FT-IR spectroscopy. The geometry around the Zn (II) center can be described as distorted tetrahedron. The crystal packing was stabilized by N–H∙∙∙Cl, N–H∙∙∙S and C–H∙∙∙S intermolecular hydroge…
The influence of interface exchange coupling on magnetic anisotropy in the antiferromagnetic oxide/Ni system is investigated. We show how interfacial exchange coupling can be employed not only to pin the magnetization of the ferromagnetic layer but also to support magnetic anisotropy to orient the easy magnetization a…
Particle coagulation technology is a facile approach to prepare large-scale and narrowly dispersed polymer particles. However, diverse shapes such as ellipsolid, snowman, dumbbell, and trimer among others were obtained if the cross-linker was directly added into the initial reaction mixtures due to the restriction of…

Ionised field strength on the ground level is one of fundamental electromagnetic environment parameters of high voltage direct current transmission lines. Field mill is generally employed to measure the ground‐level ionised field. In order to reduce the field distortion caused by the field mill probe on the ground, a…
BACKGROUND: A theoretical model has been previously proposed to optimize the structure of the electrical probe memory system, whereby the optimal thickness and resistivity of DLC capping layer and TiN under layer are predicted to be 2 nm, 0.01 Ωm, and 40 nm, 2×10-7 Ωm,respectively However, there is no experimental evi…

Two groups of molecularly imprinted NO adsorbents were prepared by molecularly self-assembly procedures, in which methanoic acid, acetic acid, ethanedioic acid were used as templates; acrylic acid (AA) and acryl amide (AAM) were used as functional monomers, respectively. The pore size distribution and the special surf…
Dimerization of nematic liquid crystals can enhance the birefringence (Δn) without red-shifting the absorption band edge. At a nematic temperature of 10 °C higher than the crystal melting point, Δn of the bistolane-based dimer is 0.51, which is 1.2 times larger than that of the corresponding monomer (0.42), but the di…
In this study, traditional (univariate) method of processing to the wet mechanochemical treatment were applied to obtain both SrCO3 and (NH4)2SO4 from celestite (SrSO4)-(NH4)2CO3-H2O mixtures in a planetary ball mill.X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, and chemical…
In this paper heterogeneous subjects are investigated, namely laminated nanoparticles and flat-layered media. Common feature of objects under consideration is presence of surfaces divided into slabs with different physical characteristics. The aim of the work is to demonstrate large possibilities and certain preferenc…
