Effect of AlN and Al2O3 additions on the phase relationships and morphology of SiC Part I Compositions and properties
(Kluwer Academic Publishers; Springer Science+Business Media, 1999-11)
X-ray diffraction was utilized to follow the transformation from β-SiC (3C) to the various α-SiC polytypes in the presence of AlN and Al 2 O 3 additives after hot pressing from 1700 to 2100°C. The 2H- and 6H-polytypes of ...
Biaxial Yield for Nonlinearly Viscoelastic Materials with a Strain Clock
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-03)
A constitutive equation with a dilatation dependent reduced time is used to model the mechanical response of solid amorphous polymers such as polycarbonate. Such constitutive equations have the property that stress relaxation ...
Fabrication of in situ TiC reinforced aluminum matrix composites Part I: Microstructural characterization
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-11)
In the present work traditional ingot metallurgy plus rapid solidification techniques were used to in situ produce Al-TiC composites with refined microstructures and enhanced dispersion hardening of the reinforcing phases. ...
Rehydration of Polymeric, Aqueous, Biphasic System Facilitates High Throughput Cell Exclusion Patterning for Cell Migration Studies
(WILEY‐VCH Verlag, 2011-08-09)
This paper describes a cell‐exclusion patterning method facilitated by a polymeric aqueous two‐phase system. The immersion aqueous phase (polyethylene glycol) containing cells rehydrates a dried disk of the denser phase ...
Acoustic emission during fatigue of Ti-6Al-4V: Incipient fatigue crack detection limits and generalized data analysis methodology
(Kluwer Academic Publishers; Chapman & Hall ; Springer Science+Business Media, 1992-06)
The fundamentals associated with acoustic emission monitoring of fatigue crack initiation and propagation of Ti-6Al-4V were studied. Acoustic emission can detect and locate incipient fatigue crack extensions of approximately ...
Asymmetric 3D Elasticâ Plastic Strainâ Modulated Electron Energy Structure in Monolayer Graphene by Laser Shocking
(Wiley Periodicals, Inc., 2019-05)
Graphene has a great potential to replace silicon in prospective semiconductor industries due to its outstanding electronic and transport properties; nonetheless, its lack of energy bandgap is a substantial limitation for ...

Preparation and characterization of polymer/inorganic nanoparticle composites through electron irradiation
(Kluwer Academic Publishers; Springer Science + Business Media, Inc., 2006-04)
In this paper, we report a new method to prepare the polymer/inorganic nanoparticle composites using electron irradiation-induced polymerization. The mixture of nanoparticles and MMA solution were co-irradiated by 1.6 MeV ...
Exploiting In Situ Redox and Diffusion of Molybdenum to Enable Thin‐Film Circuitry for Low‐Cost Wireless Energy Harvesting
(SpringerWiley Periodicals, Inc., 2019-02)
Direct additive fabrication of thin‐film electronics using a high‐mobility, wide‐bandgap amorphous oxide semiconductor (AOS) can pave the way for integration of efficient power circuits with digital electronics. For power ...
Role of preheating and specific energy input on the evolution of microstructure and wear properties of laser clad Fe-Cr-C-W alloys
(Kluwer Academic Publishers; Springer Science+Business Media, 2000-07)
Synthesis of Fe-Cr-C-W alloy (10 : 4 : 1 : 1, wt(%)) was carried out on AISI 1016 steel substrate using laser cladding technique which lead to the development of a suitable alternate for cobalt bearing wear resistant alloys. ...
