some researchers believe that because of the severe earthquake and tsunami in the fourth century h., a large part of siraf submerged by the persian gulf water fluctuations. based on the available evidence and also by the archaeological survey of the siraf coastal surrounding areas, the author argues that despite the devastating earthquake occurred to destroy much of the coastal architectural st...

Structures and binding in small water-benzene complexes (1-8 water molecules and 1-2 benzene molecules) are studied using the general effective fragment potential (EFP) method. The lowest energy conformers of the clusters were found using a Monte Carlo technique. The binding energies in the smallest clusters (dimers, trimers, and tetramers) were also evaluated with second order perturbation the...

To determine the relative importance of the confining geometry and nanoscopic length scale versus water/interface interactions, the dynamic interactions between water and interfaces are studied with ultrafast infrared spectroscopy. Aerosol OT (AOT) is a surfactant that can form two-dimensional lamellar structures with known water layer thickness as well as well-defined monodispersed spherical r...

Historically, access to water resources had always been a key issue in the formation and perpetuation of ancient cities, more importantly in the arid and semi-arid regions like the central plateau of Iran. Based on the environmental situations, Persian civilization considered ecological realities and social interaction of conservation and proper distribution of the water to sustain its availabi...

Selective filtration of gas, water, and liquid or gaseous oil is essential to prevent possible environmental pollution and machine/facility malfunction in oil-based industries. Novel materials and structures able to selectively and efficiently filter liquid and vapor in various types of solutions are therefore in continuous demand. Here, we investigate selective gas-water-oil filtration using t...
