Research paper thumbnail of Solid State CARBON13 NMR Studies of the Morphology and Orientational Order of Polymer Fibers

A fundamental understanding of the mechanism of fiber formation requires a detailed knowledge of ... more A fundamental understanding of the mechanism of fiber formation requires a detailed knowledge of fiber morphology. However due to the limitation of current techniques, the crystallization behavior is still not fully understood. Modern solid state NMR techniques enable one to approach this subject from different aspects. In this work we conducted detailed studies of the morphology of as-spun PET (poly

Research paper thumbnail of EXAFS investigation of the morphology of immobilized Rh(PPh 3) 3Cl on phosphinated MCM-41

Journal of Molecular Catalysis A-chemical, 2010

Rh(PPh3)3Cl was immobilized on a (OEt)3Si(CH2)3PPh2 modified MCM-41 to form a stable hydrogenatio... more Rh(PPh3)3Cl was immobilized on a (OEt)3Si(CH2)3PPh2 modified MCM-41 to form a stable hydrogenation catalyst. The morphology of the catalyst was characterized by X-ray absorption spectroscopy. The EXAFS results indicates that the immobilized Rh catalyst has an average Rh–Os (Os is a surface oxygen) and Rh–Si bond distances of 2.01Å and 3.15Å, respectively, suggesting that monomeric Rh complex bonds to the

Research paper thumbnail of Versatile approach for the synthesis of novel seven-membered iminocyclitols via ring-closing metathesis dihydroxylation reaction

Bioorganic & Medicinal Chemistry, 2004

Seven-membered iminocyclitols with diverse diastereomers were prepared starting with d- and l-ser... more Seven-membered iminocyclitols with diverse diastereomers were prepared starting with d- and l-serines and employing ring-closing olefin metathesis and dihydroxylation reaction sequence. The iminocyclitols were assayed for glycosidase inhibition and compound 20 was found to be a competitive inhibitor for β-glucosidase with Ki 26.3μM.
