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 ...
Synthesis and Optical Characterization of Mg1-xNixO Nanostructures
An attempt has been made here to synthesize nano-powders via sol-gel process. These powders are shown to possess an f.c.c. (NaCl-type) structure with a typical lattice parameter of Å for when decomposition of dried ...
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
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 ...
Lead-free epitaxial ferroelectric material integration on semiconducting (100) Nb-doped SrTiO3 for low-power non-volatile memory and efficient ultraviolet ray detection
(Springer Nature, 2015-07-23)
We report lead-free ferroelectric based resistive switching non-volatile memory (NVM) devices with epitaxial (1-x)BaTiO3-xBiFeO(3) (x = 0.725) (BT-BFO) film integrated on semiconducting (100) Nb (0.7%) doped SrTiO3 (Nb: ...
High efficiency planar-type perovskite solar cells with negligible hysteresis using EDTA-complexed SnO2
(Springer Nature, 2018-08-13)
Even though the mesoporous-type perovskite solar cell (PSC) is known for high efficiency, its planar-type counterpart exhibits lower efficiency and hysteretic response. Herein, we report success in suppressing hysteresis ...
Giant strain with ultra-low hysteresis and high temperature stability in grain oriented lead-free K0.5Bi0.5TiO3-BaTiO3-Na0.5Bi0.5TiO3 piezoelectric materials
(Springer Nature, 2015-02-26)
We synthesized grain-oriented lead-free piezoelectric materials in (K0.5Bi0.5TiO3-BaTiO3-xNa(0.5)Bi(0.5)TiO(3) (KBT-BT-NBT) system with high degree of texturing along the c (c-cubic) crystallographic orientation. We ...
Recent Progress on PZT Based Piezoelectric Energy Harvesting Technologies
Energy harvesting is the most effective way to respond to the energy shortage and to produce sustainable power sources from the surrounding environment. The energy harvesting technology enables scavenging electrical energy ...
Enhanced torsional actuation and stress coupling in Mn-modified 0.93(Na0.5Bi0.5TiO3)-0.07BaTiO(3) lead-free piezoceramic system

Room temperature ferromagnetic resonance in hetero-epitaxial BTO-BFO/LSMO magnetoelectric composite
(American Institute of Physics, 2018-10-30)
We synthesized epitaxial BTO-BFO heterostructure with decreased leakage and simultaneously improved the multiferroic properties. This study provides new direction for ferromagnetic resonance studies, in high quality BTO-BFO ...
