There is a growing interest in food industry to replace the synthetic chemicals by the natural products with bioactive properties from plant origin. The aim of this study was to determine the chemical composition of Mentha pulegium essential oil and to characterize the antimicrobial activities of the essential oil. The essential oil of Mentha pulegium was analyzed by GC-MS. The evaluation of th...

the preparation of nanostructure type manganese oxide and cobalt oxide materials with the smallest particle size is reported here. the nanorod manganese oxide and cobalt oxide nanotube were prepared via a sol-gel reaction in reverse micelles from kmno4 and cocl2 with respectively source at room-temperature. the structure and surface morphology of the obtained manganese oxide were studied by mea...

the improvement of the physical properties of indium tin oxide (ito) layers is quite advantageous in photovoltaic applications. in this study the ito film is deposited by rf sputtering onto p-type crystalline silicon (c-si) with (100) orientation, multicrystalline silicon (mc-si), and glass substrates coated with zno and annealed in vacuum furnace at 400°c. electrical, optical, structural and m...

The chemical constituents of the essential oil of Ruta graveolens L. from aerial parts collected from Iran were analyzed by GC and GC/MS. The oil yield of the dried plant obtained by hydrodistillation was 0.4% (v/w). Nineteen compounds, representing for 95.2% of the oil, were identified. The main classes of compounds were found to be ketons(46.6%) and sesquiterpenoids (13.3%) and monoterpenoids...

in order to compare the effects of different spraying of nano zinc oxide and zinc oxide, the arable irrigated wheat was conducted in two separate trials in 2011-2014 lands of abadeh city.experiments were conducted in a randomized complete block design, with five treatments and five replications.in the first experiment, treatments included the application of nano zinc oxide to five levels ( 0 , ...

Background & Aim: Ziziphora L. genus belongs to the Lamiaceae family, which has important medicinal and aromatic plant species. In current study, essential oil chemical compositions of two Ziziphora L. species (Z. tenuior L. and Z. clinopodioides Lam.) were investigated. Experimental: The flowering branches of Z. tenuior and Z. clinopodioides</e...

although the solubility of oxygen in molten aluminum alloys is said to be negligible, the fresh surface of the melt oxidizes quickly in the air and an oxide film is formed on the melt surface. oxide-metal-oxide sandwich technique is a method for the study of short-time surface oxide films. in this research, air was blown at 0.5 atmosphere into the melts of al-1mg and al-6mg alloys by means of a...
