in this research, mesoporous silica was applied as the host of corrosion inhibitor (molybdate). the loaded mesoporous silica was dispersed in an epoxy matrix. the composite was then coated on the mild steel plate. results showed that the corrosion resistance of the scratched epoxy/mesoporous silica loaded by molybdate was better than the one without molybdate or neat epoxy. on the other hand, e...

   In this research, mesoporous silica was served as the host of molybdate (corrosion inhibitor). The loaded mesoporous silica was dispersed in a paint matrix. The composite was then coated on the carbon steel surface. Polarization and electrochemical impedance spectroscopy (EIS) tests showed that the corrosion resistance of the scratched paint containing molybdate loaded mesoporous silica ...

By controlling the interaction between cationic surfactant micelles and ammonium metatungstate during the formation of mesoporous silica structure, highly dispersed tungsten carbide (WC) nanoparticles of 2.0 nm in diameter on mesoporous silica nanospheres were synthesized at lower concentration of ammonium metatungstate. With additional ammonium metatungstate, a novel mesoporous silica nanobamb...

spherical mesoporous silica mcm-41 was synthesized for adsorptive removal of sulfur compounds from fossil fuels using 1mm solution of dibenzothiophene (dbt) in dodecane as model oil. the prepared silica adsorbent has been characterized by nitrogen adsorption-desorption analysis as well as small angle x-ray scattering (saxs), and transmission and scanning electron microscopy (sem) methods. resul...

Eu ions-doped cubic mesoporous silica thin films with a thickness of about 205 nm were prepared on silicon and glass substrates using triblock copolymer as a structure-directing agent using sol–gel spin-coating and calcination processes. X-ray diffraction and transmission electron microscopy analysis show that the mesoporous silica thin films have a highly ordered body-centered cubic mesoporous...

Hollow mesoporous silica spheres have recently attracted increasing attention. However, effective synthesis of uniform hollow mesoporous spheres with controllable well-defined pore structures for fundamental research and practical applications has remained a significant challenge. In this work, a straightforward and effective "cationic surfactant assisted selective etching" synthetic strategy w...

Eu3+ ions-doped cubic mesoporous silica thin films with a thickness of about 205 nm were prepared on silicon and glass substrates using triblock copolymer as a structure-directing agent using sol-gel spin-coating and calcination processes. X-ray diffraction and transmission electron microscopy analysis show that the mesoporous silica thin films have a highly ordered body-centered cubic mesoporo...

BACKGROUND This study aimed the use of mesoporous silica under the naturally transformable Neisseria meningitidis, an important pathogen implicated in the genetic horizontal transfer of DNA causing a escape of the principal vaccination measures worldwide by the capsular switching process. This study verified the effects of mesoporous silica under N. meningitidis transformation specifically unde...
