Silver Doped Zinc Oxide Thin Film Production by Thermionic Vacuum Arc (TVA) Technique

In this paper, silver (Ag)doped Zinc Oxide(ZnO) thin films were prepared on glass and silicon substrate by using a thermionic vacuum arc technique. The surface, structural, optical characteristics of silver doped thin films have been examined by X-Ray diffractometer (XRD), field emission scanning emission electron microscopy (FESEM), atomic force microscopy (AFM), and UV-Visible spectrophotometer. As a result of these measurements, Ag, Zn and ZnO reflection planes were determined for thin films formed on Si and glass substrate. Nano crystallites have emerged in FESEM and AFM images. The produc..read more

Chromium, Manganese and Zinc Levels in the Biological Samples of Type 1 Diabetic Mellitus Children, Reside in Different Areas of Sindh, Pakistan

T1DM is the most acquainted childhood immune-caused onset and may lead to early mortalities and morbidities. It can emanate in any age group but is highest reported in lesser than 18 years of age. In Pakistan only, T1DM institutes ~ 2% of the all diabetic population. This work was formulated to assess the concentration of manganese (Mn), zinc (Zn) and chromium (Cr) in blood, scalp hair and serum samples of diabetic mellitus type 1 children age ranged (1–5), (6-10) and (11-14) years of both genders (male and female), compared with similar sex and age referent subjects. For sample pretreatment,..read more

Investigation of The Relationship Between The Substituent and Nonlinear Optical Properties in 2- (Phenyl ((4-Vinylphenyl)Amino) Methyl)Phenol Derivative Compounds by DFT Method

In this study, NLO properties and substituent relationship of the recently synthesized three alkylaminophenol compounds, which have electron-donating and electron-withdrawing groups were investigated. The polarizability (<α>), the anisotropy of the polarizability (<Δα>), groundstate dipole moment (μ) and the first-order hyperpolarizability (β) were studied. HF method and DFT/B3LYP, WB97XD methods with 6-311++ G(d,p) set were used for calculations. p-Nitroaniline was selected as a reference compound. Also, EHOMO (the highest occupied molecular orbital energy), ELUMO(the lowest unoccupied mol..read more

Organo-Clay as Adsorbent for Removal of Fenoxaprop-p-ethyl from Water Samples; A Statistical Approach

In this study, fuller’s earth (FE) modified with sodium dodecylbenzene sulphonic acid was used for adsorptive removal of fenoxaprop-p-ethyl (FPE) herbicide from water samples and statistical validation of the experimental observations was accomplished. All the adsorption experiments were conducted in batch mode. The effect of pH, agitation time, adsorbent dose and initial herbicide concentration on adsorption process was studied. About 98.5% adsorption efficiency was achieved at initial analyte concentration of 1000 mg L-1 at pH 6 within 60 min at adsorbent dose of 0.1 g. The adsorption kineti..read more

Synthesis and Applications of Polyacrylate basedWater White Clear Polymeric Material Fortified with Carbon Nano-Tubes for Durable, Protective and Corrosion Resistance Coatings Used in Applied Automobile Industry

Acrylates are esters of acrylic acid formed by the reaction of acrylic acid with alcohols. These acrylic esters produced by polymerization of combination with different acrylic monomers to produce the materials with enhanced characteristics for coating applications. The acrylate-based polymers have been prepared by varying the nature and ratios of the monomers. Moreover, the properties of the polymeric materials have been further improved by compositing with the nano-fillers i.e. carbon nanotubes. Further, the materials have been coated on different surfaces to evaluate the coating characteris..read more

The Ring Formation Mechanism in Cyclization of Berberine

Berberine hydrochloride is a natural alkaloid with significant antitumor activities against many types of cancer cells, can be synthesized by cyclic reaction with hydrochloride condensate and glyoxal as raw materials and copper chloride as catalyst. In this study, the transition and energy change for the each reaction step was calculated by the density functional theory program Dmol3 in Materials Studio 2017. and the results testified that there are two ring formation in the cycliztion process, and according to the result we proposed the mechanism of this cyclization reaction. We also use infr..read more

Synthesis and Characterization of Sm-Ho-CeO2 Compounds Produced by Different Synthesis Methods

The most important part of a solid oxide fuel cell is the ceramic electrolyte. In this study, cerium oxide (CeO2) was used as the ceramic electrolyte, and different dopant types were used to increase total conductivity. In this study, the most commonly used Sm, and the less frequently used Ho elements were doped simultaneously. As a result, the effect of dope and different synthesis methods on electrolyte properties was evaluated. Three rates were studied with the total amount of Sm-Ho being 20%. The effect of the dopant types on conductivity with critical radius effect was investigated. These..read more

Efficient Construction of 4-aryl-5,8-epiminobenzo[7]annulenes based on a Cascade Michael/Cyclization Reaction

A practical method was developed for the gain of potentially biologically active 4-aryl-5,8-epiminobenzo[7]annulenes using tropinone as starting material with an azabicyclo[3.2.1]octan skeleton. In an effort to improve product yield, reaction process conditions were optimized and the cascade Michael/cyclization reaction went most smoothly using tetrahydrofuran as solvent in the presence of DBU at 60°C for 10 hours. More diverse 4-aryl-5,8-epiminobenzo[7]annulenes were synthesized in good yields and structurally identified by NMR, FTIR and mass spectrometry analysis. The assembly of the heteroc..read more

Stereoselective Synthesis, Spectral Characterization, Docking and Biological Screening of Coumarin Derivatives

The compounds being synthesized in present research are chiral in nature so for getting enantiopure compounds, stereoselective synthesis was carried out by organocatalysis. The importance of enantiopure compounds can not be overstated because the living systems are chiral in nature and response of enantiomers can be very different in living systems. The organocatalysed synthesis was accumplished using 4-hydroxycoumarin and variously substituted dibenzylideneacetones as reactants and the organocatalyst being used was 9-amino-9-deoxyepiquinine. The range of enantioselectivity achieved was 24-95%..read more
