Poly(organophosphazene)s and the sol–gel technique
(John Wiley & Sons, Ltd., 1999-05)
We report a survey of the utilization of phosphazene materials in combination with metal alkoxide precursors to form ceramics through the sol–gel technique. Silicon, titanium, zirconium and aluminum three-dimensional oxide ...
Triple Junction Mobility: A Molecular Dynamics Study
(Kluwer Academic Publishers; Springer Science+Business Media, 1999-11)
We present a molecular dynamics simulation study of the migration of individual grain boundary triple junctions. The simulation cell was designed to achieve steady state migration. Observations of the triple junction angle ...
Polyhedral liquid crystal silsesquioxanes
(John Wiley & Sons, Ltd., 1999-04)
Synthetic routes towards monodisperse polyhedral liquid-crystalline silsesquioxanes are described. The liquid-crystalline phase behaviour of these structurally uniform materials, with various silsesquioxane core and mesogenic ...
Cyclic siloxanes and silsesquioxanes as cores and frameworks for the construction of ferrocenyl dendrimers and polymers
(John Wiley & Sons, Ltd., 1999-04)
Starting from 1,3,5,7-tetramethylcyclotetrasiloxane as core, novel ferrocenyl silicon-containing dendrimers have been constructed up to the third generation, which contains 16 peripheral ferrocene moieties. As precursors ...
A pH- and ionic strength-responsive polypeptide hydrogel: Synthesis, characterization, and preliminary protein release studies
(John Wiley & Sons, Inc., 1999-12-15)
A novel polypeptide hydrogel has been synthesized by crosslinking poly(L-glutamic acid) (PLG) with poly(ethylene glycol) (PEG). The PLG-PEG hydrogel was shown to be highly hydrophilic, and the extent of swelling varied ...
The effect of spacer length on the polymerization of diacetylenes in sams on gold surfaces
(WILEY‐VCH Verlag GmbH & Co. KGaA, 1999-08)
The influence of the molecular architecture of diacetylene disulfides on the structure and polymerizability of self assembled monolayers on gold was investigated. The position of the diacetylene group was varied systematically ...
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 ...
Synthesis and characterization of cage and bicyclic silsesquioxanes via dehydration of silanols
(John Wiley & Sons, Ltd., 1999-04)
Synthesis of cage and ladder silsesquioxanes by the dehydration of silanols using dicyclohexylcarbodiimide (DCC) is described. The reaction of 1,3-dicyclohexyldisiloxane-1,1,3,3-tetraol with DCC gave octa(cyclohexylsilsesquioxane) ...
