In the process of crude oil desalination, the aim is to separate dispersed phase of brine from oil phase. The project aim is the use of carbon nano-adsorbent for remov-al of salt from crude oil that, unlike other methods of salt separation from crude oil currently used, is a simple, inexpensive method with good ability to remove salt from crude oil. In this study, first, four types of carbon ad...

In this study, carbon nano-micro spheres with tightly controllable size, regularand perfect shape, high yields and narrow size distribution were prepared simply fromglucose and DI water as precursors using a hydrothermal method. By setting the initialconcentration of glucose solution and changing the hydrothermal process time at aconstant temperature of 160 °C, carbon spheres with various sizes...

Ultraviolet waves, because of their short wavelength, have a high energy and considerable damaging effects on surfaces. Protection against ultraviolet radiations is one of the finishing treatments done on surfaces exposed to sunlight. The importance of this issue in relation to human health, due to complications such as skin burns and cancer, is doubled. Up t...

OBJECTIVES This study was conducted to determine whether nano-sized carbon black exposure results in greater damage in high fat diet-induced overweight rats than normal weight ones and to identify the possible causes of any differences. METHODS Two groups of Sprague-Dawley rats allocated by body weight (normal and overweight) were exposed to aerosolized nano-sized carbon black for 6 hours a d...

aim : the aim of this study is to design multi-walled carbon nanotubes (mwcnts) loaded with paclitaxel (ptx) anti-cancer drug and investigate its anti-cancerous efficacy of human gastric cancer. the sidewall surfaces of pristine mwcnts are highly hydrophobic. a major goal in carbon nanotube chemistry has been functionalization for aqueous solubility, and exploiting nano-tubes as macromolecules ...

Using DC-Plasma Enhanced Chemical Vapour Deposition (PECVD) system, the impact of pure Co onthe growth of diamond-like carbon (DLC) nano-structures were investigated. In this study, Acetylene(C2H2) was diluted in H2 and used as the reaction gas and Cobalt (Co) nano-particles were used asthe catalyst. The effect of preparing Co catalyst at temperatures of 240°C and 350°C and growthconditions was...

The historical notion regarding the inability of gold to catalyze reactions has been discarded in view of recent studies, which have clearly demonstrated the high catalytic efficiency of supported nano-gold catalysts. Although nano-Au catalysts are known to catalyze a variety of reactions, the major focus has been on CO oxidation catalysis. In this work we focus on the important aspects related...

A sensing device is modeled and discussed in this paper. The modeling is done by using carbon nanotubes. This carbon nanotube based sensing device makes it possible produce huge amount of nano chips as a disposable cartridge for diagnostic purposes. Modeling of nano-electrode, characterization and electrochemical detection of DNA hybridization is discussed here. The results shows that the impor...
