Ion beam modification of metals: Compositional and microstructural changes
(Elsevier, 1989)
Ion implantation has become a highly developed tool for modifying the structure and properties of metals and alloys. In addition to direct implantation, a variety of other ion beam techniques such as ion beam mixing, ion ...
Curing reaction and product properties of polysulfones terminated with active functional groups
(Wiley Subscription Services, Inc., A Wiley Company, 1991-11-20)
The curing processes of maleimide-terminated polyether sulfone oligomers ( M n from 1100 to 3000) and ethynyl-terminated polysulfone prepolymers ( M n from 2600 to 12000) were investigated by means of DSC. The ...
Vapor-based polymer coatings for potential biomedical applications
(John Wiley & Sons, Ltd., 2006-12)
Over the last decade, biology and biotechnology have witnessed an extraordinary development spanning genomics, proteomics, and metabolics. This progress was so rapid and definite that it not only changed the face of modern ...
Soluble InP and GaP Nanowires: Self-Seeded, Solution–Liquid–Solid Synthesis and Electrical Properties
(WILEY-VCH Verlag, 2009-04-27)
A facile, self-seeded , solution–liquid–solid growth of soluble InP and GaP nanowires with a very low amount of native point defects with respect to the carrier concentrations have been synthesized (see scheme) and ...
Morphology and primary crystal structure of a silk-like protein polymer synthesized by genetically engineered Escherichia coli bacteria
(Wiley Subscription Services, Inc., A Wiley Company, 1994-08)
The morphology and primary crystal structure of SLPF, a protein polymer produced by genetically engineered Escherichia coli bacteria, were characterized. SLPF is a segmented copolymer consisting of amino acid sequence ...
Ring-opening polymerization of epoxy end-terminated poly(ethylene oxide) as a route to highly crosslinked materials with exceptional swelling behavior (II)
(John Wiley & Sons, Ltd., 2007-08)
Highly swellable poly(ethylene oxide) (PEO) gels were prepared by anionic ring-opening polymerization of diepoxy end-capped PEO (3400 g mol −1 ) and PEO (8000 g mol −1 ) using dianionic glycerol and glycolic acid initiators ...
Flow equations for graphite
(Elsevier, 1976)
In analyzing erosion of graphite at high strain rate (~107 sec-1) and temperature (~4000[deg]C), it is necessary to have some approximation for the constitutive equation. Data for graphite from static and low strain rate ...
Crosslinking chemistry for high-performance polymer networks
(Elsevier, 1994-11)
A new thermally reactive monomer has been designed and synthesized that brings novel crosslinking chemistry to high-performance polymers. This monomer (XTA) is a derivative of terephthalic acid and was based on the thermal ...
Multicompartmental Microcylinders
(WILEY-VCH Verlag, 2009-06-08)
FarbenprÄchtige SÄulen : Eine einfache und dabei skalierbare Methode zur Herstellung multikompartimentalisierter Mikrozylinder, bei denen innerer Aufbau, SeitenverhÄltnis und OberflÄche gezielt eingestellt werden kÖnnen, ...
Synthesis and Erosion Properties of PEG-Containing Polyanhydrides
(WILEY-VCH Verlag, 2007-05-10)
To tailor the erosion rate of polyanhydrides while retaining their surface erosion characteristics, new three-component polyanhydrides of sebacic acid, 1,3-bis( p -carboxyphenoxy)propane and poly(ethylene glycol) were ...
