Porous poly( L -lactic acid)/apatite composites created by biomimetic process
(John Wiley & Sons, Inc., 1999-06-15)
Highly porous poly( L -lactic acid)/apatite composites were prepared through in situ formation of carbonated apatite onto poly( L -lactic acid) foams in a simulated body fluid. The highly porous polymer foams (up to 95% ...
Poly(Α-hydroxyl acids)/hydroxyapatite porous composites for bone-tissue engineering. I. Preparation and morphology
(John Wiley & Sons, Inc., 1999-03-15)
Tissue engineering has shown great promise for creating biological alternatives for implants. In this approach, scaffolding plays a pivotal role. Hydroxyapatite mimics the natural bone mineral and has shown good bone-bonding ...
Sulfided heterogeneous, bimetallic Ru/Mo catalysts derived from mixtures of Ru 3 (CO) 12 (or RuCl 3 ) and a molybdenum heteropolyanion: The reactions of ethanol with tetrahydroquinoline
(John Wiley & Sons Ltd., 1992-09)
Efforts have been made to develop Ru/Mo bimetallic catalyst systems for hydrodenitrogenation (HDN) of tetrahydroquinoline (THQ). In the course of these studies, it was discovered that in ethanol, under hydrogen and in the ...
Synthesis and characterization of precursors for group II metal aluminates
(John Wiley & Sons, Ltd., 1997-10)
Precursors to Group II metal aluminates (MAI 2 O 4 , M=Mg, Ca, Ba, Sr) are synthesized from inexpensive starting materials including Group II metal oxides/hydroxides, Al(OH) 3 , triethanolamine (TEA) and ethylene glycol, ...
Synthetic nano-scale fibrous extracellular matrix
(John Wiley & Sons, Inc., 1999-07)
Biodegradable polymers have been widely used as scaffolding materials to regenerate new tissues. To mimic natural extracellular matrix architecture, a novel highly porous structure, which is a three-dimensional interconnected ...
Polyfunctional cubic silsesquioxanes as building blocks for organic/inorganic hybrids
(John Wiley & Sons, Ltd., 1998-10)
Cubic silsesquioxanes, [RSiO 1.5 ] x , potentially offer access to organic/inorganic hybrids wherein the exact shape, size and mechanical properties of the inorganic component are perfectly defined. Furthermore, by ...
Epitaxial growth and characterization of GaAs/Al/GaAs heterostructures
(Elsevier, 1990-04-01)
We report on transmission electron microscopy, secondary ion mass spectroscopy, X-ray and Raman scattering studies of GaAs/Al/GaAs heterostructures grown by migration enhanced epitaxy.
Octa(3-chloroammoniumpropyl) octasilsesquioxane
(John Wiley & Sons, Ltd., 1999-04)
The octahydrochloride salt of octa(3-aminopropyl)octasilsesquioxane can be isolated in 30% yields by controlled hydrolytic condensation of 3-aminopropyltriethoxysilane in strongly acidic methanol. The analytically pure ...
