Inside Cover: Multicompartmental Microcylinders (Angew. Chem. Int. Ed. 25/2009)
(WILEY-VCH Verlag, 2009-06-08)
Multicompartmental microcylinders can be produced by a combination of electrohydrodynamic co-spinning and microsectioning, as described by J. Lahann et 14al. in their Communication on page 144589 14ff. The number of ...
Rate and temperature effects on the fracture toughness of a rubber-modified epoxy
(Elsevier, 1993-04)
A series of three-point bend fracture toughness tests was performed at various loading rates and temperatures on both rubber-modified and unmodified epoxy specimens. The fracture toughness of the modified samples was ...
The stability of SiO-based ceramics containing ZRO2 and other oxides
(Elsevier, 1983)
Calculations of thermochemical equilibria, using the program SOLGASMIX, have defined the conditions and compositions of SiO-based ceramics in which stable ZrO2 particles can be obtained. The results are compared with ...
Radiation-induced segregation in multicomponent alloys: Effect of particle type
(Elsevier, 1994-06)
The problem of irradiation-assisted stress-corrosion cracking (IASCC) in reactor cores is currently being addressed using different types of particle irradiation (electrons, protons, and heavy ions) to study the effect of ...
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 ...
Structural and mechanical behavior of layered zirconium phosphonate as a distributed phase in polycaprolactone
(Wiley Subscription Services, Inc., A Wiley Company, 2009-10-15)
Mixed-surface octyl/methoxyundecyl Α-zirconium phosphonates (ZrPs) were investigated as distributed nanoscale fillers, in concentrations up to 50% w/w, for the purpose of increasing the elastic modulus and yield strength ...
Ultrasonic measurements of the elastic moduli of liquid crystalline polymers
(Elsevier, 1992)
The five independent elastic moduli of extruded rods of two thermotropic liquid crystalline polymers, Vectra B900 and Vectra A950, and the nine independent moduli of an injection-moulded bar of Vectra A950 have been measured ...
Solution-Based Evolution and Enhanced Methanol Oxidation Activity of Monodisperse Platinum–Copper Nanocubes This work was partially supported by the NSF (DMR-0731382 & CHM-0616436), DOE (DE-FG02-07ER86296), and the Research Foundation of SUNY. We thank Dr. Jibao He and Dr. Amar Kumbhar for their assistance with the TEM studies.
(WILEY-VCH Verlag, 2009-05-25)
Shape-controlled catalysis : High-quality Pt–Cu nanocubes with an average size of about 8 14nm (see picture, scale bar=20 14nm) were synthesized from a high-temperature organic solution system in the presence of various ...
X-Ray Microanalysis in the Environmental SEM: A Challenge or a Contradiction?
(Springer-Verlag; Springer-Verlag Wien, 2000-04)
In this paper, the application of X-ray energy dispersive spectroscopy in the environmental scanning electron microscope is reviewed. Various techniques that have been used to remove the effects of the beam spreading in ...
Ba[Si(OCH 2 CH 2 O) 3 ], a Hexaalkoxysilicate Synthesized from SiO 2 This work was supported by the Air Force Office of Scientific Research. We would like to thank Prof. Linda Nazar, Waterloo, and Prof. Florence Babonneau, Paris, for continuing collaborations, especially for running solid-state NMR studies; and Prof. R. J. P. Corriu for numerous helpful discussions that have made this publication possible.
