Synthesis of heterogeneous phosphine-free palladium-based catalyst assemblies via solid phase extraction and their characterization

Sobhi Daniel; Prabhakara Rao, P; Nandakumar, M; Prasada Rao, T (Elsevier Science, 2005)

The synthesis of heterogeneous phosphine-free palladium-based catalyst materials was accomplished in a straightforward, two-step reaction using solid phase extraction. This involves functionalization of solid inorganic ...

Preconcentrative separation of palladium(II) using palladium(II) ion-imprinted polymer particles formed with different quinoline derivatives and evaluation of binding parameters based on adsorption isotherm models

Sobhi Daniel; Prem E J Babu; Prasada Rao, T (Elsevier Science, 2005)

Palladium(II) ion-imprinted polymer (IIP) materials were synthesized by thermally polymerizing the ternary complexes of palladium(II) with amino (AQ) or hydroxy (HQ) or mercapto (MQ) derivatives of quinoline and 4-vinyl-pyridine. ...

Synthesis, characterization, and hyperpolarizability measurements of main-chain azobenzene molecules

Smitha, P; Asha, S K; Pillai, C K S (Wiley-Blackwell, 2005)

A series of new AB type azobenzene monomers based on various substituted phenols and higher order fused/extended aromatic rings were synthesized and their hyper-polarizability tensor beta determined by hyper-Rayleigh ...

Montmorillonite K10 clay-catalyzed synthesis of substituted 1-aryl indenes from Baylis-Hillman adducts

Shanmugam, P; Rajasingh, P (The Chemical Society of Japan, 2005)

An eco-friend method for the synthesis of 1-aryl indenes from Baylis-Hillman adducts using Mont. K10 and microwave combination as catalyst system and a procedure for the synthesis of beta- phenyl-substituted-protected ...

Stereoselective synthesis of tri- and tetrasubstituted oxepanes via n-Bu3SnH mediated 7-endo-trig vinyl radical cyclisation

Shanmugam, P; Rajasingh, P (Pergamon-Elsevier Science, 2005)

A stereoselective 7-endo-trig cyclisation of homopropargyl and phenyl homopropargyl] derivatives of Baylis-Hillman adducts using n-Bu3SnH/AlBN mediated vinyl radical cyclisation affords tri- and tetrasubstituted oxepanes, ...

Comparative evaluation of neutral protease production by Aspergillus oryzae in submerged and solid-state fermentation

Sandhya, C; Sumantha, A; Szakacs, G; Pandey, A (Elsevier Science, 2005)

A comparative study was carried out on the production of neutral protease using agro-industrial residues as substrate in solid-state fermentation (SSF) and submerged fermentation (SmF). Seven fungal cultures, viz. three ...

Dye sensitization of nanocrystalline TiO2: enhanced efficiency of unsymmetrical versus symmetrical squaraine dyes

Saji Alex; Santhosh, U; Suresh Das (Elsevier Science, 2005)

A series of novel symmetrical and unsymmetrical squaraine dyes have been synthesized and their comparative efficiencies as photosensitizers in dye sensitized solar cells (DSSCs) containing nanocrystalline TiO2 photoelectrodes ...
