at the present study, different properties of sarin with the formula [(ch3)2cho]ch3pof was studiedin gas phase. geometrical optimizations of sarin, single point calculation, nmr and electricalparameters were carried out in gas phase with the hartee -fock method coupled to 6-31g* basis setsfor all atoms. the results obtained from a comparison between tables and charts came up fordiscussion and a...

in this study, the effects of moisture content and corn variety on the physicochemical properties of popcorn were investigated and modeled using response surface methodology. each of the two corn varieties (hybrid corn ksc 600 pc and american) was prepared with a range of moisture (six moisture levels ranging from 10 to 20%) and popped by a hot air popper. variety and moisture content affected ...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
in the first part of this thesis we explored wetting and its dynamics for small droplets. first, we showed how a simple feature of water droplets on a surface, i.e. laplace pressure, can be exploited to build a micropump. we investigated capillary pumping in microchannels both experimentally and numerically. putting two droplets of different sizes at the in/outlet of a microchannel, will ge...
