Precise structural studies of nano-crystalline minerals using diffraction techniques have been hindered by the broad diffraction peaks found in their diffraction patterns. In this thesis, I have applied molecular scale techniques such as High-Energy X-ray Diffraction and Molecular Dynamics simulations to study the structure and reactivity of two nano-minerals of important environmental signific...
substitution of two or four carbon atoms by nitrogen in the corannulene molecule as a carbon nanostructure was done and the obtained structures were optimized at mp2/6-31g(d) level of theory. calculations of the nucleus-independent chemical shift (nics) were performed to analyze the aromaticity of the corannulene rings and its derivatives upon doping with n at b3lyp/6-31g(d) level of theory. re...
mirage effect is contactless and non destructive method which has been used a lot to determine thermal properties of different kind of samples , transverse photothermal deflection ptd in skimming configuration with ccd camera and special programs is used to determine thermal conductivity of porous silicon ps film. ps samples were prepared by electrochemical etching. thermal conductivity wit...
Tubular structures built from amphiphilic molecules are of interest for nano-sensing, drug delivery, and structuring of oils. In this study, we characterized the tubules built in aqueous suspensions of a cholesteryl nucleoside conjugate, cholesterylaminouridine (CholAU) and phosphatidylcholines (PCs). In mixtures with unsaturated PCs having chain lengths comparable to the length of CholAU, two ...
crystalline antimony sulfide (sb2s3) with nanorods morphology was successfully prepared via hydrothermal method by the reaction of elemental sulfur, antimony and iodine as starting materials with high yield at 180°c for 24h.using oxidation reagents like iodine as an initiator of redox reaction to prepare sb2s3 is reported for first time. crystal growth of sb2s3 was done by increasing reaction t...
