Nanocrystalline SiO2–HClO4, as a newly reported catalyst, has been used as an efficient and reusable catalyst for the synthesis of pyrimidine derivatives. The procedure can be successfully applied to the efficient synthesis of mono substituted pyrimidine derivatives, using triethyl orthoformate, ammonium acetate, methyl ketone derivatives. In practice, this method is a combination of a satisfactory synthesis and more significantly easy product isolation and purification. A simple, high yielding in the presence of perchloric acid–functionalized silica nanosphere as a catalyst is described. The catalyst could be used at least five times without any change in the activity. Full characterization of the catalyst was performed by XRD, EDX, UV–Vis, TGA spectra and also by SEM and TEM images.

An environmentally benign and clean synthesis of aryl-hydrazones by reacting variety of carbonyl compounds with thiosemicarbazide, semicarbazide, aminoguanidine, and phenyl hydrazine has been achieved using aqueous extract of Acacia concinna pods as a natural surfactant type catalyst. We found that the aqueous extract of Acacia concinna pods could be effectively used for the synthesis of aryl-hydrazones. This efficient process proceeds smoothly in aqueous medium at room temperature within a very short period of time. All the products were obtained by simple filtration. The low cost, easy availability of the catalyst and simple reaction conditions are the notable features of the present method.

The aim of this study was to investigate the Stachys turcomanica phytochemical compounds, antimicrobial and antioxidant activity of methanolic extract. The volatile constituents from the aerial parts of Stachys turcomanica growing wild in Iran were obtained by hydrodistillation and analyzed by GC and GC-MS. In the GC-MS analysis, Forty-six components representing 81.1% of the oil were identified. The main constituents the oil were 1-octen-3-ol (13.4%), β -pinene (7.9%), α -pinene (5.6%), α -bisabolol(4.4%), ar-curcumene(4.0%) and β –myrcene(3.7%).The phytochemical analysis revealed the presence of alkaloids , flavonoids and terpenoid in varying concentration . The antioxidant activity of aerial parts of methanolic extract was studied in vitro by 2’2’-diphenylpicrylhydrazyl (DPPH) radical–scavenging activity. The methanolic extract of Stachys turcomanica leaves exhibited amaximum DPPH scavenging activity of (81.61±0.78) %at10mg/mL followed by aerial parts of plant. Whereas for BHT (standard) was found to be (94.79±0.75) % at the same concentration. Methanol solvent to screen the antimicrobial activity selected phytopathogens by agar diffusion method. The maximum antibacterial (phytopathogene) activities were observed on Xanthomonascampestrispv.Campestris,Agrobacterium sp.and Pseudomonas viridiflava.

The aim of this work is to probe the influence of nanoclay and turmeric spends content on microcrystalline of vinyl ester hybrid nanocomposites. A series of vinyl ester hybrid nanocomposites have been fabricated with varying amounts of TS viz., 0, 2.5, 5, 7.5 and 10 % w/w along with 2% nanoclay. The microcrystalline parameters such as crystallite size and lattice strain of vinyl ester hybrid nanocomposites have been measured by using wide-angle X-ray scattering (WAXS). These values were correlated with physico-mechanical properties of the vinyl ester hybrid nanocomposites with and without turmeric spent to understand the holistic behaviour of the nanocomposites. Two prominent Bragg reflections at major peak in the 2θ region 17.35 – 17.79º and a small shoulder in the 2θ region around 40.00 - 42.44º were observed in the wide-angle X-ray diffraction patterns of the vinyl ester hybrid nanocomposites films of various ratios.

In this article electrochemical determination of captopril at the surface of the platinum coated nanoporous gold film (PtNPGF) electrode is reported using the cyclic voltammetry and amperometry. For the preparation of PtNPGF, the surface of NPGF electrode was covered with Cu layer using underpotential electrochemical deposition (UPD).Afterward, the copper layer is replaced with platinum ions via a spontaneous redox reaction to have a uniform Ptoverlayer. Under the optimized conditions, the amperometry peak current of captopril increased linearly with captopril concentration in the ranges of 4.70×10-8 to 4.57×10-5mol L−1. The detection limit of captopril was 1.2×10-8mol L−1. The results show a very good precision (R.S.D < 2.4%), suitable selectivity and very stable response for captopril. The proposed sensor was successfully applied for the determination of captopril in the urine samples of patient human.

This paper presents a new gel combustion method to synthesize palladium nanoparticles, palladium oxide (PdO) nanoparticles and palladium-palladium oxide nanocomposites. In the proposed method, there are some effective parameters including palladium chloride concentration, polyvinyl alcohol (PVA) concentration, acid concentration, solvent composition and combustion temperature that their values are investigated and optimized by the "one at a time" method. The experimental data shows that the combustion temperature is the main factor that controls the sample composition to obtain palladium, palladium oxide or palladium-palladium nanocomposites. Characterization of the synthesized samples is performed by SEM, TEM, XRD and BET specific surface area measurements. The optimized sample consisted of clusters; each cluster is composed of smaller nanoparticles with an average diameter of 25 mm and 10 m2. g-1 specific surface areas. The optimized Pd-PdO nanocomposite is successfully used as nanocatalyst for the hydrogen revolution.

The quantitative structure–property relationship (QSPR) method is used to develop the correlation between structures of crude oil hydrocarbons (80 compounds) and their boiling point and water solubility. Sub-structural molecular fragments (SMF) calculated from structure alone were used to represent molecular structures. A subset of the calculated fragments selected using stepwise regression (forward and backward steps) (SR) was used in the QSPR model development. Multiple linear regressions (MLR) are utilized to construct the linear prediction model. The prediction results agrees well with the experimental values of these properties. The comparison results indicate the superiority of the presented models and reveal that it can be effectively used to predict the boiling point temperatures and water solubility values of crude oil hydrocarbons from the molecular structures alone. The stability and predictivity of the proposed models were validated using internal validation (leave one out and leave many out) and external validation. Application of the developed models to test set of 16 compounds demonstrates that the new models are reliable with good predictive accuracy and simple formulation.

Fe3O4 magnetic nanoparticles were synthesized by co-precipitation of Fe2+ and Fe3+ in aqueous NaOH. Then silica was coated on the obtained nanoparticles and the whole composite was functionalized with chlorosulfonic acid in CH2Cl2. The obtained nanocomposite (Fe3O4@SiO2-SO3H) was characterized by FT-IR, VSM and XRD techniques and was used as an efficient catalyst in condensation reaction of indoles and aldehydes, and excellent yields of the desired products were obtained. The catalyst was recycled and used for successive runs with no considerable loss of activity. The indole products in their conjugated form were capable of selective sensing of CN- anion in solution.

In this study, undoped ZnO and doped with Fe and Mn nanostructures were synthesized by hydrothermal method. The morphology of nanostructures was characterized by Scanning Electron Microscope. The electrochemical response of the carbon paste electrode modified with nanoparticles of ZnO and also ZnO doped with Fe and Mn toward levodopa (L-Dopa) was studied. Studies of cyclic voltammetry using provided modified electrode showed electro catalytic properties for electro-oxidation of L-Dopa and a significant reduction in anodic over voltage compared to bare electrode was observed. Best response was obtained in terms of the current enhancement, overvoltage reduction, and reversibility improvement of the L-Dopa oxidation reaction under experimental conditions by modified electrode with zinc oxide nanoparticles doped with iron.
