An easy and convenient microwave-assisted synthesis of a library of s-triazinyl piperazines and piperidines, which, in addition to 4-aminobenzonitrile contain 8-hydroxyquinoline is described. The newly synthesized analogues were then subjected to determine their efficacy against some human pathogenic bacterial and fungal strains as 3 Gram negative bacteria (K. pneumoniae, S. typhi, P. vulgaris)...

Abstract: In the course of the development of modem synthetic methods in the field of asymmetric synthesis the SAMP-/RAMP-hydrazone method opens a highly diastereoand enantioselective route to a great variety of carbonyl compounds, alcohols, amines and heterocycles. In this paper recent advances in the development of biomimetic C-C bond formations, such as the synthesis of C2-symmetric ketodiol...

Block copolymer micelles and shell cross-linked nanoparticles (SCKs) presenting Click-reactive functional groups on their surfaces were prepared using two separate synthetic strategies, each employing functionalized initiators for the controlled radical polymerization of acrylate and styrenic monomers to afford amphiphilic block copolymers bearing an alkynyl or azido group at the a-terminus. Th...

The imide-functionalized polynorbornene films exhibited excellent optical transparency in the visible range as well as high thermal stability over 200 degrees C. The indium tin oxide (ITO) thin films were coated on the imide-functionalized polynorbornene films at various deposition temperatures by employing radio-frequency (r.f.) planar magnetron sputtering system. The resulting ITO-coated imid...

Electrospun poly (vinyl alcohol) [PVA] nanowebs functionalized with a commercially available microbiocidal solution ReputexTM 20 were prepared. The active ingredient of ReputexTM 20 is polyhexamethylene biguanides, a safe antiseptic. Fourier Transform Infrared spectroscopy confirmed the functionalization of PVA nanowebs. Functionalized nanowebs were characterized by evaluating their antimicrobi...

Mesopore walls of hierarchically meso-/microporous zeolites (MFI, BEA and LTA) are covered with silanol groups, so that the zeolites can be functionalized with various organic groups via silylation; the organic-functionalized hierarchical zeolites exhibit hydrothermal stability and reusability in catalytic applications, as compared with organic-functionalized mesoporous silica.
