Investigation of infrared absorption spectra of copper phosphate glasses containing some rare earth oxides
(1990)
The spectra of copper-lutetium-phosphate and copper-erbium-phosphate glasses have been studied within the spectral range 4000 to 400 cm- by Fourier transform infrared spectroscopy. Incorporation of a small amount of lutetium ...
Infrared spectroscopic study of vacuum evaporated amorphous thin films of MoO3-SiO
(1990)
A series of amorphous MoO3-SiO thin films of varying compositions were investigated by infrared spectroscopy. In some cases, a shift in band frequency was observed. Some new peaks appeared when SiO was mixed in MoO3. These ...
Temperature programmed reduction of silica supported nickel catalysts
(1993)
Nickel oxide promoted catalysts are prepared by simple precipitation, precipitation from homogeneous solution and impregnation methods and their reduction behavior is monitored with temperature programmed reduction (TPR) ...
Polymers and oligomers with transverse aromatic groups and tightly controlled chain conformations
(1998)
Anionic ring-opening polymerisation of spiro[cyclopropane-1,9′-fluorene] with fluorenyl anion as initiator yields polymers 1 with chains which are essentially all-anti and have transversely-oriented fluorenyl groups, as ...
Ene Reaction of Arylallyl Alkenes with C60. A Mechanistic Approach
(1999)
(Matrix Presented) The ene reaction of arylallyl alkenes with C60 occurs either by a concerted mechanism or by the reversible formation of a charged or a dipolar intermediate, followed by the C-H(D) breakage in a rate-limiting ...
Vanadium chemistry and biochemistry of relevance for use of vanadium compounds as antidiabetic agents
(1995)
The stability of 11 vanadium compounds is tested under physiological conditions and in administration fluids. Several compounds including those currently used as insulin-mimetic agents in animal and human studies are stable ...
Factors Affecting Solution Properties of Vanadium(V) Compounds: X-ray Structure of β-cis-NH4[VO2(EDDA)]1
(1996)
The solution properties of two isomeric forms of the V-EDDA complex (the symmetric α-cis and asymmetric β-cis) have been studied using multinuclear NMR spectroscopy. The isomerization constant of the aqueous equilibrium ...
Near-monodisperse α-hydroxy and α,ω-dihydroxy amine-based polymers: Synthesis and characterization
(1999)
α-Hydroxy and α,ω-dihydroxy polymers of 2-(dimethylamino)ethyl methacrylate (DMAEMA) of various molecular weights were synthesized by group transfer polymerization (GTP) in tetrahydrofuran (THF), using 1-methoxy-1-(trime ...
A Slow Exchanging Vanadium(V) Peptide Complex: Vanadium(V)-Glycine-Tyrosine
(1995)
The solution structure and rate of formation for a vanadium(V)-peptide complex, vanadium(V)-glycine-tyrosine (V-Gly-Tyr), is examined. Multinuclear NMR spectroscopic studies suggest the amide nitrogen is deprotonated and ...
