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 ...
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 ...
High thermal stability of piezoelectric properties in (Na0.5Bi0.5TiO3)(x)-(BaTiO3)(y)-(Na0.5K0.5NbO3)(1-x-y) ceramics
(AIP Publishing, 2013-01-01)
We report the piezoelectric and ferroelectric properties of (Na0.5Bi0.5TiO3)(x)-(BaTiO3)(y)-(Na0.5K0.5NbO3)(1-x-y) ceramics for Na0.5K0.5NbO3 rich end of composition (x, y <= 0.04 mol. %). These compositions were found to ...
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 ...
Low-frequency nanotesla sensitivity in Metglas/piezoelectric/carbon fiber/piezoelectric composites with active tip mass
(AIP Publishing, 2011-02-01)
We report nanotesla sensitivity in Metglas/piezoelectric/carbon fiber/piezoelectric laminates with active tip mass operating in the vicinity of second bending mode. The peak magnetoelectric response for the laminate with ...
A Review on Low-Grade Thermal Energy Harvesting: Materials, Methods and Devices
(MDPI, 2018-08-14)
Combined rejected and naturally available heat constitute an enormous energy resource that remains mostly untapped. Thermal energy harvesting can provide a cost-effective and reliable way to convert available heat into ...
Discovery and ramifications of incidental Magnéli phase generation and release from industrial coal-burning
(Nature Publishing Group, 2017-01-12)
Coal, as one of the most economic and abundant energy sources, remains the leading fuel for producing electricity worldwide. Yet, burning coal produces more global warming CO2 relative to all other fossil fuels, and it is ...
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 ...
Synthesis and Behavior of Cetyltrimethyl Ammonium Bromide Stabilized Zn1+xSnO3, (0 <= x <= 1) Nano-Crystallites
(PLOS, 2016-05-26)
We report synthesis of cetyltrimethyl ammonium bromide (CTAB) stabilized Zn1+xSnO3+x (0 ≤ x ≤1) nano-crystallites by facile cost-effective wet chemistry route. The X-ray diffraction patterns of as-synthesized powders at ...
High-Efficiency Skutterudite Modules at a Low Temperature Gradient
(MDPI, 2019-11-11)
Thermoelectric skutterudite materials have been widely investigated for their potential application in mid-temperature waste heat recovery that has not been efficiently utilized A large amount of research has focused on ...
