Molecular dynamics solutions of 1,2-dimethoxyethane in aqueous solution: influence of the water potential

Article Abstract:

The conformational, structural and dynamic properties of 1,2-dimethoxyethane (DME)/water solutions are analyzed using TIP4P, MCY, SPC and SPC/E potentials for water. Results show that solution composition affects the dependence of the properties of DME/water solutions on water models. Water models had little impact on the structural and conformational properties of dilute solutions. In more concentrated solutions, water molecules interacted with DME molecules while water/water and water/DME interactions between water models varied.

Fluorescence and EPR characteristics of Mn2+-doped ZnS nanocrystals prepared by aqueous colloidal method

Article Abstract:

Research was conducted to examine the fluorescence characteristics of Mn:ZnS crystallites using electron paramagnetic resonance spectroscopy. The samples had an average diameter of 4 mn and were prepared using an aqueous colloidal technique under 266 nm light excitation. Results revealed that Mn:Zns nanocrystals prepared by the aqueous colloidal technique did not demonstrate lifetime shortening effect in the Mn2+ emission arising from quantum confinement.

Water-soluble CdS quantum dots prepared from a refluxing single precursor in aqueous solution

Article Abstract:

The first aqueous preparation of luminescent CdS QDs from a single precursor is reported. These water-soluble CdS quantum dots with tunable sizes between 25 and 40 angstorm were prepared from a readily prepared [(2,2'-bipyridine)Cd(SC{O}Ph)2] complex by simply refluxing in an aqueous solution.
