The adsorption of nucleotides on the surface nanocrystalline cerium dioxide (pHpzc = 6.3) in NaCl solutions was investigated using multi-batch experiments over a wide range pH. obtained results were interpreted as formation outer and inner sphere complexes with participation phosphate moieties. Basic Stern complexation model applied to obtain quantitative equilibrium reaction constants.

The study of groundwater–surface water interaction has attracted growing interest among researchers in recent years due to its wide range implications from the perspectives management, ecology and contamination. Many studies shed light on conditions a local scale only, without exploring regional angle. To provide broad historical overview interaction, review research carried out Denmark was und...

the construction of underground tunnel plays a more and more important role in the development of big cities. one of the most important problems caused by the construction of the tunnel is that underground excavation will cause large settlement of the ground and buildings. previous studied showed the difference between numerical and experimental results. in this study the case study of niyayesh...
