Cyclodextrin-functionalized mesostructured silica nanoparticles for removal of polycyclic aromatic hydrocarbons
(Academic Press Inc., 2017)Polycyclic aromatic hydrocarbons (PAHs) are the byproducts of the incomplete combustion of carbon-based fuels, and have high affinity towards DNA strands, ultimately exerting their carcinogenic effects. They are ... -
Density profile of a Bose-Einstein condensate inside a pancake-shaped trap: Observational consequences of the dimensional cross-over in the scattering properties
(Elsevier Science B.V., 2002)It is theoretically well known that two-dimensionality of the scattering events in a Bose-Einstein condensate introduces a logarithmic dependence on density in the coupling constant entering a mean-field theory of the ... -
The effect of anions of transition metal salts on the structure of modified mesostructured silica films and monoliths
(Elsevier, 2007)The structure of the preformed LC mesophase of water:transition metal salt ([M(H2O)6]X2):acid (HX):oligo(ethylene oxide) (or Pluronics):tetramethylorthosilicate (TMOS) mixture during hydrolysis and partial polymerization ... -
Electroinitiated polymerization of 2-chloroethylvinyl ether
(1998)The electroinitiated polymerization of 2-chloroethylvinyl ether via controlled potential conditions has been achieved. The kinetics of the polymerization were determined by cyclic voltammetry at different temperatures in ... -
Fabrication of polymer micro needles for transdermal drug delivery system using DLP based projection stereo-lithography
(Elsevier, 2016)Fabrication of micro needles, which reduce pain during insertion and lessen tissue injury, has recently attracted great interest. Different manufacturing systems have been utilized for the advancement of micro needles such ... -
Immobilization of invertase in conducting polymer matrices
(Elsevier, 1997-10)This paper reports a novel approach in the electrode immobilization of an enzyme, invertase, by electrochemical polymerization of pyrrole in the presence of enzyme. The polypyrrolelinvertase and polyamide/polypyrrole/invertase ... -
A near IR di-styryl BODIPY-based ratiometric fluorescent chemosensor for Hg(II)
(Elsevier, 2010)A novel BODIPY-based near-IR emitting probe as a selective and sensitive fluorophore for Hg(II) is synthesized. This versatile BODIPY fluorophore is functionalized for long wavelength emission at the 3 and 5 positions via ... -
Novel molecular building blocks based on the boradiazaindacene chromophore: applications in fluorescent metallosupramolecular coordination polymers
(2009)We designed and synthesized novel boradiazaindacene (Bodipy) derivatives that are appropriately functionalized for metal-ion-mediated supramolecular polymerization. Thus, ligands for 2-terpyridyl-, 2,6-terpyridyl-, and ... -
Oligomerization of ethylene in a slurry reactor using a nickel/sulfated alumina catalyst
(American Chemical Society, 1997)During the oligomerization of ethylene over heterogeneous catalysts, the production of α-olefins may be lowered because of an accompanying deactivation of catalyst resulting from strong adsorption of products, by isomerization ... -
Organization of bridging organics in periodic mesoporous organosilicas (PMOs)-polarization micro-raman spectroscopy
(Wiley, 2001)The organization of bridging organics in oriented periodic mesoporous organosilica film (OPMOF) was demonstrated using the polarization micro-Raman spectroscopy (PMRS) in conjunction with powder x-ray diffraction (PXRD) ... -
Pd nanocube decoration onto flexible nanofibrous mats of core-shell polymer-ZnO nanofibers for visible light photocatalysis
(Royal Society of Chemistry, 2017)Plasmonic enhancement for electron-hole separation efficiency and visible light photocatalysis was achieved by Pd nanocube decoration on a ZnO nanolayer coated onto electrospun polymeric (polyacrylonitrile (PAN)) nanofibers. ... -
