Abstract We have developed a simple method to prepare nano-(ZrC 0.93 , ZrO 2- polymorphs)@carbon composites with graphite/amorphous carbon content and adjustable Zr/C ratio based on using multistep tube furnace plasma-assisted heat treatment of zirconium-loaded sulfonated styrene–divinylbenzene (STY-DVB) copolymers. Pre-pyrolysis STY-DVB ion exchangers 2 8 mass % DVB at temperatures between 100...

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 ...
