Giant self-biased magnetoelectric coupling in co-fired textured layered composites
(AIP Publishing, 2013-02-01)
Co-fired magnetostrictive/piezoelectric/magnetostrictive laminate structure with silver inner electrode was synthesized and characterized. We demonstrate integration of textured piezoelectric microstructure with the ...
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 ...
Materials for the Spine: Anatomy, Problems, and Solutions
(MDPI, 2019-01-14)
Disc degeneration affects 12% to 35% of a given population, based on genetics, age, gender, and other environmental factors, and usually occurs in the lumbar spine due to heavier loads and more strenuous motions. Degeneration ...
Compositionally Graded Multilayer Ceramic Capacitors
(Springer Nature, 2017-09-27)
Multilayer ceramic capacitors (MLCC) are widely used in consumer electronics. Here, we provide a transformative method for achieving high dielectric response and tunability over a wide temperature range through design of ...
Structural Resemblance Between Droop Controllers and Phase-Locked Loops
(IEEE, 2016)
It is well known that droop control is fundamental to the operation of power systems and now the parallel operation of inverters, while phase-locked loops (PLLs) are widely adopted in modern electrical engineering. In this ...
Computing Functional Gains for Designing More Energy-Efficient Buildings Using a Model Reduction Framework
(MDPI, 2018-11-23)
We discuss developing efficient reduced-order models (ROM) for designing energy-efficient buildings using computational fluid dynamics (CFD) simulations. This is often the first step in the reduce-then-control technique ...
The Influence of the Specimen Shape and Loading Conditions on the Parameter Identification of a Viscoelastic Brain Model
(Hindawi Publishing Corporation, 2013)
The mechanical properties of brain under various loadings have been reported in the literature over the past 50 years. Step-and-hold tests have often been employed to characterize viscoelastic and nonlinear behavior of ...
Ear Deformations Give Bats a Physical Mechanism for Fast Adaptation of Ultrasonic Beam Patterns
(American Physical Society, 2011-11-14)
A large number of mammals, including humans, have intricate outer ear shapes that diffract incoming sound in a direction-and frequency-specific manner. Through this physical process, the outer ear shapes encode sound-source ...
Flexible Margin Kinematics and Vortex Formation of Aurelia aurita and Robojelly
(PLOS, 2014-06-06)
The development of a rowing jellyfish biomimetic robot termed as “Robojelly”, has led to the discovery of a passive flexible flap located between the flexion point and bell margin on the Aurelia aurita. A comparative ...
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 ...
