In a molten-salt solar power tower, liquid salt at 290oC (554oF) is pumped from a ‘cold’ storage tank through the receiver where it is heated to 565oC (1,049oF) and then on to a ‘hot’ tank for storage. When power is needed from the plant, hot salt is pumped to a steam generating system that produces superheated steam for a conventional Rankinecycle turbine/generator system. From the steam gener...

Due to the necessity of using highly efficient power generation systems to reduce fuel consumption and air pollution, the integration of different energy systems is promising modification to achieve higher efficiency. In this paper, the integration of an Internal Reforming Solid Oxide Fuel Cell (IRSOFC)-Gas Turbine (GT)-Organic Rankine Cycle (ORC) system has been proposed. In this regard, therm...

the removal of organic precursors of disinfection by-products (dbps), i.e. natural organic matter (nom), prior to disinfection is considered as the most effective approach to minimise the formation of dbps. trihalomethanes (thms) as the main group of dbps are categorized and considered to have the potentiality of increasing the rate of liver, kidney and cns adverse effects. this study which pre...

photocatalytic degradation of toxic organic compound in water, soil and air by semiconductor catalysts such as tio2 and zno have received much attention over the last two decades. however, the low quantum yield, easy agglomeration and difficult post-separation of these inorganic catalysts limit their application for large-scale applications. metal-organic frameworks (mofs) are the latest class ...

polyvinylpyrrolidone  /  nickel  oxide  (pvp/nio)  dielectrics  were fabricated  with  sol-gel  method  using  0.2  g  of  pvp  at  different working  temperatures  of  80,  150  and  200  ºc.  structural  properties and surface morphology of the hybrid films were investigated by x-ray  diffraction  (xrd)  and  scanning  electron microscope  (sem) respectively. energy dispersive x-ray spectrosc...

immidiate managementinfants and children with acute metabolic crisis require immediate treatment to prevent further acute deterioration and long-term sequelae.early and appropriate treatment before confirmation of the diagnosis is life-saving.eliminate intake of the precursors of possibly toxic metabolites.this applies most often to suspected inborn errors of amino acid or organic acid metaboli...
