Metal oxide nanocrystals/mesoporous carbon composite materials are promising in the energy storage field. However, construction of stoichiometric ternary nanocrystals-functionalized mesoporous remains a great challenge. Herein, synthesis ultradispersed and ultrasmall LiTiO2 nanocrystals/ordered composites via chelation-mediated multicomponent coassembly strategy is reported. In this case, self-...

fe3o4-containing cotton-like mesoporous silica system (fe3o4@ncsm) was studied with regard to its performance towards the photodecolorization of bromothymol blue (btb) aqueous solution. the surface properties of the functionalized catalyst were analyzed by a series of characterization techniques like ftir, xrd, bet, sem and tem. the n2 adsorption–desorption analysis shows that the mesostructure...

Antibiotic resistance is a global problem and bacterial biofilms contribute to its development. In this context, study aimed perform the synthesis characterization of seven materials based on silica mesoporous nanoparticles functionalized with three types fluoroquinolones, along Cu2+ or Ag+ species evaluate antibacterial properties against Staphylococcus aureus, Enterococcus faecalis, Escherich...

Evaluating toxicological responses of engineered nanomaterials such as silica nanoparticles is critical in assessing health risks and exposure limits. Biological assays can be used to evaluate cytotoxicity of individual materials, but specific nano-bio interactions-which govern its physiological response-cannot currently be predicted from materials characterization and physicochemical propertie...

Mesoporous silica functionalized with a 2-hydroxy-naphthyl moiety has been synthesized and characterized by standard techniques like powder X-ray diffraction, N2 adsorption/desorption studies, transmission electron microscopy and spectral studies like FT-IR, UV-visible, fluorescence and 13C and 29Si solid state NMR. The functionalized silica material showed significant enhancement in its emissi...

The mesoporous carbon (CMK-3) functionalized with ethylenediamine (EDA) has been synthesized (CMK-3-EDA) and applied as a new mesoporous adsorbent for removal of Cu(II) and Pb(II) cations from aqueous solutions. Nitrogen adsorption–desorption measurements (BET) show that surface area, pore size and pore volume of CMK-3 were significantly changed after amine modification. The BET surface area an...

Mesoporous titania nanoparticles (MTNs) with excellent biocompatibility (LC(50)≈ 400 μg mL(-1)) and a large surface area (ca. 237.3 m(2) g(-1)) were synthesized and further functionalized with a phosphate-containing fluorescent molecule (i.e. flavin mononucleotide; FMN) and loaded with an anticancer drug (i.e. Doxorubicin) for successful intracellular bioimaging and drug delivery, respectively,...

We report on a chemical-sensing method based on the silica-micelle mesophase wherein both a fluoroionophore and a masking agent are embedded. Using this method, a highly selective detection of metal ions in an aqueous solution has been successfully demonstrated. Furthermore, simultaneous analyses of multisamples using a sensor array composed of functionalized mesoporous thin films were demonstr...
