Nanoscale Bacteria‐Enabled Autonomous Drug Delivery System (NanoBEADS) Enhances Intratumoral Transport of Nanomedicine
(Wiley, 2018-12-05)
Cancer drug delivery remains a formidable challenge due to systemic toxicity and inadequate extravascular transport of nanotherapeutics to cells distal from blood vessels. It is hypothesized that, in absence of an external ...
On the Lawrence-Doniach and Anisotropic Ginzburg-Landau models for layered superconductors
(Siam Publications, 1995-02)
The authors consider two models, the Lawrence-Doniach and the anisotropic Ginzburg-Landau models for layered superconductors such as the recently discovered high-temperature superconductors. A mathematical description of ...
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 ...
Piecewise-Constant-Model-Based Interior Tomography Applied to Dentin Tubules
(Hindawi Publishing Corporation, 2013)
Dentin is a hierarchically structured biomineralized composite material, and dentin's tubules are difficult to study in situ. Nano-CT provides the requisite resolution, but the field of view typically contains only a few ...
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 ...
Tunable self-biased magnetoelectric response in homogenous laminates
(AIP Publishing, 2012-12-01)
In this study, we demonstrate self-biased magnetoelectric effect in homogenous two-phase magnetostrictive-piezoelectric laminates. Our results illustrate the method for tuning the magnitude of self-bias effect and provide ...
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 ...
Defect and adsorbate induced ferromagnetic spin-order in magnesium oxide nanocrystallites
(AIP Publishing, 2012-05-01)
We report the correlation between d(0) ferromagnetism, photoluminescence (PL), and adsorbed hydrogen (H-) species in magnesium oxide (MgO) nanocrystallites. Our study suggests that the oxygen vacancies, namely singly ionized ...
