Phonon transport in an initially twisted polyvinyl acetate nanofiber
(AIP Publishing, 2013-05-01)
A reduction in phonon thermal conductivity enhances thermoelectric performance. One method to accomplish this is by applying mechanical stress to a nanostructure. We consider an initially twisted 20 nm polyvinyl acetate ...
Ultralow equivalent magnetic noise in a magnetoelectric Metglas/Mn-doped Pb(Mg1/3Nb2/3)O-3-PbTiO3 heterostructure
(AIP Publishing, 2012-07-01)
An ultralow equivalent magnetic noise of 6.2 pT/root Hz at 1 Hz was obtained in a bimorph heterostructure sensor unit consisting of longitudinal-magnetized Metglas layers and a transverse-poled 1 mol. % Mn-doped ...
Nonlinear magnetoelectric response of a Metglas/piezofiber laminate to a high-frequency bipolar AC magnetic field
(AIP Publishing, 2013-03-01)
A nonlinear magnetoelectric (ME) response has been investigated in a Metglas/piezofiber laminate by applying a bipolar AC magnetic field (H-ac) without a DC magnetic bias. The ME voltage (V-ME) was measured for various ...
Giant magnetoelectric effect in Metglas/polyvinylidene-fluoride laminates
(AIP Publishing, 2006-08-01)
Here, the authors report thin (< 100 mu m) and flexible magnetoelectric (ME) composites consisting of Metglas (high-mu magnetostriction) and polyvinylidene-fluoride (piezopolymer) layers laminated together. Both unimorph ...
Implication of conservative and gyroscopic forces on vibration and stability of an elastically tailored rotating shaft modeled as a composite thin-walled beam
(Acoustical Society of America, 2001-03-01)
Problems related with the implications of conservative and gyroscopic forces on vibration and the stability of a circular cylindrical shaft modeled as a thin-walled composite beam and spinning with constant angular speed ...
Using transient shear rheology to determine material parameters in fiber suspension theory
(AIP Publishing, 2009-05-01)
Fiber suspension theory model parameters for use in the simulation of fiber orientation in complex flows are, in general, either calculated from theory or fit to experimentally determined fiber orientation generated in ...
Obtaining reliable transient rheological data on concentrated short fiber suspensions using a rotational rheometer
(AIP Publishing, 2009-09-01)
The conventional method for obtaining transient rheological data on short glass fiber-filled polymeric fluids is to use the parallel disk (PP) geometry in a rotational rheometer. Using the PP geometry large transient stress ...
Modeling and the signal-to-noise ratio research of magnetoelectric sensors at low frequency
(AIP Publishing, 2007-10-01)
The authors have modeled magnetoelectric (ME) laminate sensor units by considering both the ME laminate and detection circuitry. Theory predicts and experiments confirm that the signal-to-noise ratio increases with increasing ...
Modeling of shape memory alloy hybrid composites for structural acoustic control
(Acoustical Society of America, 1991-01-01)
Experimental demonstration of active vibration and structural acoustic control using shape memory alloy (SMA) hybrid composites [C. A. Rogers, in Proceedings of the International Congress on Recent Developments in Air and ...
Direct measurement of magnetoelectric exchange in self-assembled epitaxial BiFeO3-CoFe2O4 nanocomposite thin films
(AIP Publishing, 2009-05-01)
We report the direct measurement of a magnetoelectric (ME) exchange between magnetostrictive CoFe2O4 nanopillars in a piezoelectric BiFeO3 matrix for single-layer nanocomposite epitaxial thin films grown on (001) SrTiO3 ...
