One-dimensional creep tests and model studies on saturated saline soil
Yantu gongcheng xuebao, 2020 The physical and chemical interaction between soil particles and pore salt solutions in saturated saline soils has a strong influence on the mechanical behavior of soils, which makes the saline soils exhibit different deformation characteristics.

Fractional-Fractal Modeling of Filtration-Consolidation Processes in Saline Saturated Soils
Fractal and Fractional, 2020 To study the peculiarities of anomalous consolidation processes in saturated porous (soil) media in the conditions of salt transfer, we present a new mathematical model developed on the base of the fractional-fractal approach that allows considering ...

Instability of the salinity profile during the evaporation of saline groundwater [PDF]
, 2008 We investigate salt transport during the evaporation and upflow of saline groundwater. We describe a model in which a sharp evaporation-precipitation front separates regions of soil saturated with an air-vapour mixture and with saline water.

Novel Superdielectric Materials: Aqueous Salt Solution Saturated Fabric [PDF]
Materials, 2016 The dielectric constants of nylon fabrics saturated with aqueous NaCl solutions, Fabric-Superdielectric Materials (F-SDM), were measured to be >105 even at the shortest discharge times (>0.001 s) for which reliable data could be obtained using the constant current method, thus demonstrating the existence of a third class of SDM.

Multi-field coupling analysis of water-heat-salt in composite unsaturated soils
Yantu gongcheng xuebao, 2022 The multi-field coupling problem of water, heat and salt in the composite unsaturated soils composed of unsaturated clay and unsaturated sand is studied. Based on the mass and energy conservation equations for porous media, the temperature, pore pressure,

Paradoxical drying due to salt crystallization [PDF]
, 2014 We investigated how salt crystallization inside a porous building material influences the formation of a receding drying front. Nuclear Magnetic Resonance (NMR) is used to measure non-destructively both hydrogen and dissolved sodium ions simultaneously ...

Damage in porous media due to salt crystallization [PDF]
, 2010 We investigate the origins of salt damage in sandstones for the two most common salts: sodium chloride and sulfate. The results show that the observed difference in damage between the two salts is directly related to the kinetics of crystallization and ...

Charge-induced phase separation in lipid membranes [PDF]
, 2014 The phase separation in lipid bilayers that include negatively charged lipids is examined experimentally. We observed phase-separated structures and determined the membrane miscibility temperatures in several binary and ternary lipid mixtures of ...
