In the present work we report for first time carbonization of biomass waste, such as stale bread and spent coffee, in piranha solution (H2SO4-H2O2) at ambient conditions. Carbonization is fast exothermic, resulting formation carbon nanosheets decent yields 25–35%, depending on starting material. The structure morphology were verified by X-ray diffraction, Raman, photoelectron microscopy techniq...

In order to compare rectal and intravenous(IV) administration of diazepam for management of convulsions,a prospective cross-sectional case-control study was conducted on 94 convulsive infants and children referring to the Emergency department of the university hospital No.1 in Kerman.all children were randomly divided into two groups.the patients were matched with regard to the cause,type,durat...

Nowadays NMR spectroscopy becomes a powerful tool in chemistry because of the NMR chemical shifts. Hartree–Fock theory and the Gauge-including atomic orbital (GIAO) methods are used in the calculation of 29Si NMR chemical shifts of various silicate species in the silicate solution as initial components for zeolite synthesis both in gas and solution phase. Calculations have been performed at geo...

UNLABELLED BACKGROUND The aim of this study is to investigate the functions of polymers and size of nanoparticles on the antibacterial activity of silver bionanocomposites (Ag BNCs). In this research, silver nanoparticles (Ag NPs) were incorporated into biodegradable polymers that are chitosan, gelatin and both polymers via chemical reduction method in solvent in order to produce Ag BNCs. Si...

Tin anode slime is a by-product of the tin electrolytic refining process. This study investigated route to separate Sn, Sb, Bi, and Cu from after leaching with hydrochloric acid. In solvent extraction process tributyl phosphate, Sb Sn were extracted into organic phase. Bi unextracted remained in liquid stripping experiment, stripped separated HCl HNO3. aqueous phase also chemical precipitation ...

We report the synthesis of ?-SiAlON:Eu2+ phosphors from novel single source precursors in which strictly controlled chemical composition is established at molecular scale. The two-step occurs by modification perhydropolysilazane (PHPS) with Al(OCH(CH3)2)3 and AlCl3 xylene room temperature to 140 °C introduce Al PHPS network while controlling oxygen content followed reaction EuCl2 Al-modified up...

In this article, we present a web server based solution for implementing a system for intelligent navigation. In this solution we use real time collected data and traffic history to establish the best route for navigation. This is a low cost solution that is easily to implement and extend. There is no need any infrastructure at road network level except only a device that collect data about tra...

In order to shorten the development time, it is important that resources in development be focused on doing things “Right the First Time”. The cost of making a chemical compound that potentially has very attractive properties might be prohibitively high and finding a feasible alternative route quickly is imperative. History shows that even very promising drugs don’t make to market because of th...

Laser-induced fluorescence studies on mass-selected biomolecules are a promising route to understand their properties in the gas phase and probe intrinsic solvent-free environment. Fluorescence has been used investigate conformation dynamics of gaseous biomolecular ions. With Förster Resonance Energy Transfer (FRET), it is now possible obtain sensitive intramolecular distance information from l...

In this paper, a supply chain network design problem is explained which contains environmental concerns in arcs and nodes of network. It is assumed that there are some routes such as road, rail and etc. in each pair of nodes. In this model decision variables are choosing facilities to open, environmental investment level in each facility and flow of products between nodes in each route. A multi...
