In this paper solar assisted heating and absorption cooling system and domestic hot water needs for a hotel having fifty rooms in Antalya have been investigated. First of all, solar radiation and meteorological data for Antalya and heating and cooling loads of the hotel building are given. For the heating cycle, active systems using liquid as the working fluid; and for the cooling cycle, solar-...

In this work, an environmentally friendly sample pre-treatment method, Ultrasound Assisted Surfactant Enhanced Emulsification Microextraction (UASEME) followed with spectrofluorimetry was performed for determination of oxadiazon residues in water samples. After the determination of the most suitable extraction solvent and its volume, other parameters such as type and concentration of surfac...

The analytical use of ultrasound-generated emulsations has recently found a growing interest to improve efficiency in liquid-liquid microextraction since they increase the mass transfer between the two immiscible phases implied and leads to emulsification. Thus, dispersed droplets can act as efficient liquid-liquid microextraction in continuous phase, and later they can be readily separated by ...

In the present research, salting out and vortex assisted dispersive liquid–liquid microextraction based on solidification of floating organic drop microextraction (SO-VADLLME-SFODME)  for the extraction and determination of phenol and chlorophenols in water samples followed by HPLC have been studied through a novel, simple, low-cost, selectable and environment friendly (so called green) method....

A lightsail can be accelerated to ultra-high speed by the radiation pressure of a laser having an intensity order GW/m$^2$, which though presents critical challenge in thermal management lightsails. In this letter, we explore applicable regimes solid-state cooling dissipating heat additional previously explored radiative approach. We begin examining capacity cooling, and show that rate from mic...

A method based on the ultrasound-assisted solidification of floating drop microextraction technique was developed for the spectrophotometric and spectrofluorimetric determination of curcumin in turmeric powder. In this work a small volume of an organic solvent was floated on the surface of an aqueous solution. After sonication the organic solvent is solidified and separated. The effect of extra...
