RISA study on curing and thermal behavior of Cyanoacrylate/SiO2 Nanocomposite
The results of Isothermal DSC show that an increase in nano-size SiO2 content causes to decrease the initiation time, duration and energy release of polymerization. It is also obtained that the presence of nano-size SiO2 particles postpone...
A Study on Fracture Mechanism of SiO2/Cyanoacrylate Nanocomposites
In the current research role of SiO2 nanoparticle on fracture behavior of Cyanoacrylate nanocomposite has been investigated. For this purpose Cyanoacrylate matrix reinforced with different content of SiO2 nanoparticles were produced. Three...
Investigation of nano-SiO2 impact on mechanical and biocompatibility properties of cyanoacryalate based nanocomposites for dental application
Although cyanoacrylate glues are widelyused inmedicine,cyanoacrylate-based nanocomposites have
been recently suggested for dental restorative/filling applications.In the present research,SiO2
nanoparticles were usedas filler...
Mild and Efficient Iodination of Aromatic Compoundswith Trichloroisocyanuric Acid/I2/Wet SiO2 System
Iodoarenes can be obtained using trichloroisocyanuric acid/I 2 /wet SiO2 system at room temperature
with high yield in CH2 Cl2 ....
Multiwalled carbon nanotubes/polypyrrole/SiO2 composite prepared by electrodeposition technique as a new solid phase microextraction sorbent for preconcentrationon of BTEX
BTEX is the collective name of benzene, toluene, ethylbenzene, and the xylene isomers (p, m,
and o-xylenes), all being harmful volatile organic compounds (VOCs). Human exposure to these
compounds can have ...
A Mild and Simple Iodination of Phenos with Trichloroisocyanuric Acid/ I2 /Wet SiO2 Systems
