our main objective in the present study was to assess the spatial variation of chemical and physical water properties. prior to the design of groundwater quality monitoring networks, it is essential to investigate the spatial structure of the groundwater quality variables. a case study is presented which used ground water quality observations from groundwater domestic wells in the dameghan, ira...

The structure of water on metal electrodes is addressed based on first-principles calculations. Special emphasis is paid on the competition between water-metal and water-water interaction as the structure determining factors. Thus the question will be discussed whether water at metal surfaces is iceor rather liquid-like. The proper description of liquid phases requires to perform thermal averag...

1. Dietary fibre has a water holding capacity (WHC) and this is a function of the fibre source and method of measurement. Water can be associated with fibre either as trapped water or bound water. This makes it difficult to predict the ability of fibre to influence stool weight in humans. 2. Examination of various fibre concentrates for chemical composition, as neutral detergent fibre (NDF), ac...

Determining water structure in nanopores and its influence on water transport behaviour is of great importance for understanding and regulating the transport across nanopores. Here we report an ultrafast-slow flow transition phenomenon for water transport across nanopores of carbon nanotubes owing to the change in water structure in nanopores induced by temperature. By performing extensive mole...

Aquporins are intrinsic membrane proteins that function as water channel to transport water and/or mineral nutrients across biological membranes. In this study, we aimed to clarify whether water structure can be changed by the presence of ceramics and whether such a change can be determined by aquaporin. First, we confirmed that ceramics could transform tap water into active tap water by increa...

We observe potential dependent alignment and hydrogen bonding of interfacial water molecules at a charged air/water and CCl4/water interface. The interfacial potential is a result of the presence of charged soluble surfactant adsorbed to the interface. We vary the interface potential by changing the surface charge density, the ionic strength, and the temperature while monitoring OH stretching m...
