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% ...
The effect of phenotype variation on detection of linkage in the COGA data
(Wiley Subscription Services, Inc., A Wiley Company, 1999)
Error in phenotypic measurement can significantly compromise ability to detect linkage. We assessed the impact of introducing phenotypic measurement error on our ability to detect a quantitative trait locus in the Collaborative ...
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) ...
Formation of Silver and Gold Dendrimer Nanocomposites
(Kluwer Academic Publishers; Springer Science+Business Media, 1999-09)
Structural types of dendrimer nanocomposites have been studied and the respective formation mechanisms have been described, with illustration of nanocomposites formed from poly(amidoamine) PAMAM dendrimers and zerovalent ...
Quadazocine decreases responding reinforced by ethanol, sucrose, and phencyclidine fluid deliveries in rhesus monkeys: comparison to naltrexone’s effects
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1999-06)
Rationale: The endogenous opioid system may mediate the reinforcing effects of ethanol as well as sweet-tasting solutions. For example, opioid antagonists, such as naltrexone, reduce ethanol- and sucrose-reinforced ...
Application of an ordered subset analysis approach to the genetics of alcoholism
(Wiley Subscription Services, Inc., A Wiley Company, 1999)
For complex diseases, underlying etiologic heterogeneity may reduce power to detect linkage. Thus, methods to identify more homogeneous subgroups within a given sample in a linkage study may improve detection of putative ...
Chemical extraction of indigo from Indigofera tinctoria while attaining biological integrity
(Kluwer Academic Publishers; Springer Science+Business Media, 1999-08)
Indigofera tinctoria was permeabilized with 20% methanol (v/v) at 25 °C and released 8±2 μg indigo g −1 dry plant material (excluding roots). This is equivalent to 42±11% of the total indican within the cells. The plants ...
Functionalized polyhedral oligosilsesquioxane (POSS) macromers: new graftable POSS hydride, POSS α-olefin, POSS epoxy, and POSS chlorosilane macromers and POSS–siloxane triblocks
(John Wiley & Sons, Ltd., 1999-04)
A series of polyhedral oligomeric silsesquioxanes (POSS) monomers bearing silane or α-olefin substituents have been prepared and their chemistry explored. Both the POSS silanes and α-olefin monomers readily participate in ...
