Nanoscale Bacteria‐Enabled Autonomous Drug Delivery System (NanoBEADS) Enhances Intratumoral Transport of Nanomedicine
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 ...
Fear of Falling and Older Adults: Finding Balance
(Virginia Tech. Center for Gerontology, 2013-10)
Falls are a major public health concern for older adults. Annually, 1 out of every 3 Americans aged 65+ experiences a fall. According to the Centers for Disease Control and Prevention, falls are the leading cause of ...

Evaluation of Eye Injury Risk from Consumer Fireworks
(Brain Injuries and Biomechanics Symposium, 2013-09-19)
Eye injuries affect approximately two million people annually. Various experimental studies have been performed to evaluate potentially injurious conditions from blunt objects using animal and human cadaver eyes. Experimental ...
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 ...
Family Process - Autism Spectrum Disorders
Slides for a talk about family process and the importance of parenting dimensions in adolescent development. The slides list findings to date, and propose research into the influence of family on outcomes for those diagnosed ...
Back to the Future: Lösch, Isard, and the Role of Money and Credit in the Space-Economy
(Virginia Tech, 2016-08)
The recent financial crisis has been a powerful reminder that the intersectoral flow of funds is also—always and everywhere—a local phenomenon with real effects. Yet, the contemporary canon of regional economic theory has ...
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 ...
