Thermal conductivity of self-assembled nano-structured ZnO bulk ceramics
(American Institute of Physics, 2012-08-01)
In this study, we describe the changes in thermal conductivity behavior of ZnO-Al micro- and nano-two-phase self-assembled composites with varying grain sizes. The reduction in thermal conductivity values of micro-composites ...
A new method for achieving enhanced dielectric response over a wide temperature range
(Springer Nature, 2015-10-19)
We report a novel approach for achieving high dielectric response over a wide temperature range. In this approach, multilayer ceramic heterostructures with constituent compositions having strategically tuned Curie points ...
A generalized rule for large piezoelectric response in perovskite oxide ceramics and its application for design of lead-free compositions
(American Institute of Physics, 2009-06-01)
We present a general rule for the perovskite oxide ceramics: "A large piezoelectric constant in ABO(3) perovskite ceramics can be obtained by tuning the weight ratio of A and B sites, WA/WB or WB/WA, to 3. Piezoelectric ...
Enhanced piezoelectric performance from carbon fluoropolymer nanocomposites
(American Institute of Physics, 2012-12-15)
The piezoelectric performance of polyvinylidene fluoride (PVDF) is shown to double through the controlled incorporation of carbon nanomaterial. Specifically, PVDF composites containing carbon fullerenes (C-60) and single-walled ...
Origin of high piezoelectric response in A-site disordered morphotropic phase boundary composition of lead-free piezoelectric 0.93(Na0.5Bi0.5)TiO3-0.07BaTiO(3)
(American Institute of Physics, 2013-03-21)
Perovskite piezoelectric compositions near the morphotropic phase boundary (MPB) are known to exhibit high piezoelectric response. In lead-based ABO(3) compound with B-site disorder, the origin of this enhancement has been ...
Near-flat self-biased magnetoelectric response in geometry gradient composite
(American Institute of Physics, 2014-03-14)
We demonstrate a near-flat self-biased magnetoelectric (ME) effect in geometry gradient magnetostrictive-piezoelectric laminates. The near-flat behavior was characterized by a stable ME response over a wide range of magnetic ...
Structure-performance relationships for cantilever-type piezoelectric energy harvesters
(American Institute of Physics, 2014-05-28)
This study provides comprehensive analysis of the structure-performance relationships in cantilever-type piezoelectric energy harvesters. It provides full understanding of the effect of all the practical global control ...
Room-temperature magnetoelectric coupling in single-phase BaTiO3-BiFeO3 system
(American Institute of Physics, 2013-04-14)
In this paper, single-phase multiferroic ceramics of (1 - x) BaTiO3 - x BiFeO3 (BT - x BFO) were synthesized by solid-solution method in the wide range of material composition (x = 0.025 - 1.0). The changes in crystal ...
Giant piezoelectric voltage coefficient in grain-oriented modified PbTiO3 material
(Springer Nature, 2016-10-11)
A rapid surge in the research on piezoelectric sensors is occurring with the arrival of the Internet of Things. Single-phase oxide piezoelectric materials with giant piezoelectric voltage coefficient (g, induced voltage ...
Harvesting Energy from the Counterbalancing (Weaving) Movement in Bicycle Riding
(MDPI, 2012-07-30)
Bicycles are known to be rich source of kinetic energy, some of which is available for harvesting during speedy and balanced maneuvers by the user. A conventional dynamo attached to the rim can generate a large amount of ...
