DESALINATION SYSTEM WITH FLASH EVAPORATION AT LOW TEMPERATURE AND ATMOSPHERIC PRESSURE

Study and Enhancement of Flash Evaporation Desalination Utilizing the Ocean Thermocline and Discharged heat

This paper reports on the results of experimental investigations of flash evaporation from superheated jet issues vertically upward from a round straight nozzle of 81.3 mm diameter. For the investigated range of jet superheat degree and velocity, it was shown that flash evaporation enhances with initial temperature increase. Due to the increase of jet inertia and subsequently the delay of jet s...

Synthesis and Characterization of ZnO Nanostructures Grown via a Novel Atmospheric Pressure Solution Evaporation Method

In this study, a novel method called “atmospheric pressure solution evaporation (APSE)” wasdeveloped for growing of Zinc Oxide (ZnO) nanostructures on Al2O3 surface. Zinc acetate dihydrate,Polyvinyl Pyrrolidone, and deionized water were used as precursor, capping, and solvent, respectively.The growth of ZnO nanostructures from evaporated solution was performed at three temperatures of300, 400, ...

Plasma-enhanced chemical vapor deposition of zinc oxide at atmospheric pressure and low temperature

The plasma-enhanced chemical vapor deposition of aluminum-doped zinc oxide has been demonstrated for the first time at 800Torr and under 250 1C. A film resistivity of 3 10 2 O cm and a transparency of 95% from 375 to 2500 nm was obtained for deposition at 20mTorr diethylzinc, 1.0 Torr CO2, 799Torr He, a TMAl/DEZn ratio of 1:100, 41W=cm RF power, and 225 1C. The average aluminum concentration in...

Plasma-Assisted Reduction of Graphene Oxide at Low Temperature and Atmospheric Pressure for Flexible Conductor Applications.

Reduction of graphene oxide (GO) at low temperature and atmospheric pressure via plasma-assisted chemistry is demonstrated. Hydrogen gas is continuously dissociated in a microplasma to generate atomic hydrogen, which flows from the remote plasma to thin films of GO deposited on a substrate. Direct interaction with ions and other energetic species is avoided to mitigate ion-induced sputter remov...
