The title compound, C(3)H(10)NO(3)P, crystallizes in its zwitterionic form, H(3)N(+)CH(C(2)H(5))PO(O(-))(OH), with the asymmetric unit being composed by two of such entities (Z' = 2). The crystal packing leads to a sequence of hydro-phobic and hydro-philic layers. While the hydro-phobic layer comprises the aliphatic substituent groups, the hydro-philic one is held together by a series of strong...

Liquid metal loops are used for heat removal and for the study of certain magnetofluidic phenomenon like MHD (Magneto-Hydro Dynamic) effects. These loops operate at high temperatures and carry fluids that are invariably toxic in nature. To ensure the purity of fluid in a closed loop application, non-intrusive electromagnetic pumps are used. We have designed and analyzed a prototype electromagne...

Confined aquifers are formations surrounded by impermeable layers called cap rocks and bed rocks. These aquifers are suitable for the seasonal storage of thermal energy. A confined aquifer was designed to meet the cooling and heating energy needs of a residential building complex located in Tehran, Iran. The annual cooling and heating energy needs of the buildings were estimated to be 8.7...

Pump-jets have a relatively high propulsion efficiency at medium speed and in heavy-load conditions for wheeled amphibious vehicles. However, the geometry of vehicles is very special due to installation requirements pump-jet, which results an obvious resistance on wheels. In order reduce vehicle, characteristics wheels are studied. Regarding pump-jet-propelled its wheel wide range firstly analy...

Small-scale hybrid energy systems are often composed by different power production technologies and adopted in mini-grids. In this work, a Mixed Integer Linear Programming optimization algorithm has been developed to compute the optimal scheduling of micro-grid constituted Internal Combustion Generators (ICGs) Storage System that can be either conventional battery storage system or Pumping Hydr...

To achieve the carbon free electricity generation target for 2050, the penetration of renewable energy sources should further increase. To address the impacts of their unpredictable and intermittent characteristics on the future electricity grid, Pumped Hydro Energy Storage (PHES) plants should enhance their regulation capability by extending their continuous operating range far beyond the opti...
