N-(3-oxododecanoyl)-L-homoserine lactone interactions in the breast tumor microenvironment: Implications for breast cancer viability and proliferation in vitro
(PLOS, 2017-07-10)It is well documented that the tumor microenvironment profoundly impacts the etiology and progression of breast cancer, yet the contribution of the resident microbiome within breast tissue remains poorly understood. Tumor ... -
Nano-Enriched and Autonomous Sensing Framework for Dissolved Oxygen
(MDPI, 2015-08-14)This paper investigates a nano-enhanced wireless sensing framework for dissolved oxygen (DO). The system integrates a nanosensor that employs cerium oxide (ceria) nanoparticles to monitor the concentration of DO in aqueous ... -
NanoARG: a web service for detecting and contextualizing antimicrobial resistance genes from nanopore-derived metagenomes
(2019-06-07)Background Direct and indirect selection pressures imposed by antibiotics and co-selective agents and horizontal gene transfer are fundamental drivers of the evolution and spread of antibiotic resistance. ... -
Nanodispersed DO(3)-phase nanostructures observed in magnetostrictive Fe-19% Ga Galfenol alloys
(American Physical Society, 2008-03-10)Few nanometer large (<2 nm) inclusions of DO(3)-phase structure have been identified in the A2 matrix of highly magnetostrictive Fe-19% Ga alloys by high-resolution transmission electron microscopy (HRTEM). In addition, ... -
Nanodroplet-Mediated Histotripsy for Image-guided Targeted Ultrasound Cell Ablation
(Ivyspring Int Publ, 2013-01-01)This paper is an initial work towards developing an image-guided, targeted ultrasound ablation technique by combining histotripsy with nanodroplets that can be selectively delivered to tumor cells. Using extremely short, ... -
Nanogrowth twins and abnormal magnetic behavior in CoFe2O4 epitaxial thin films
(American Institute of Physics, 2008-12-15)Nanogrowth twins (GTs) have been observed in CoFe2O4 (CFO) epitaxial thin films deposited on (111) oriented SrTiO3 substrates by pulsed laser deposition. The GTs form during nucleation and growth and consist of CFO growth ... -
Nanoindentation of thin films: Simulations and experiments
(Cambridge University Press, 2009-03-01)Atomistic Simulations of nanoindentation of a 20-nm-thick Ni thin film oriented in the [111] direction were carried out to study the effects of indenter velocity and radii, interatomic potentials, and the boundary conditions ... -
Nanomaterial Disposal by Incineration
(The Royal Society of Chemistry, 2013-07-11)As nanotechnology-based products enter into widespread use, nanomaterials will end up in disposal waste streams that are ultimately discharged to the environment. One possible end-of-life scenario is incineration. This ... -
Nanomaterial enabled sensors for environmental contaminants
(2018-11-22)Abstract The need and desire to understand the environment, especially the quality of one’s local water and air, has continued to expand with the emergence of the digital age. The bottleneck in understanding ... -
Nanonet force microscopy for measuring forces in single smooth muscle cells of the human aorta
(2017-07-07)A number of innovative methods exist to measure cell-matrix adhesive forces, but they have yet to accurately describe and quantify the intricate interplay of a cell and its fibrous extracellular matrix (ECM). In cardiovascular ... -

Nanopillars with E-field accessible multi-state (N ≥ 4) magnetization having giant magnetization changes in self-assembled BiFeO3-CoFe2O4/Pb(Mg1/3Nb2/3)-38at%PbTiO3 heterostructures
(Springer Nature, 2018-01-26)We have deposited self-assembled BiFeO3-CoFe2O4 (BFO-CFO) thin films on (100)-oriented SrRuO3-buffered Pb(Mg1/3Nb2/3)0.62Ti0.38O3 (PMN-38PT) single crystal substrates. These heterostructures were used for the study of ... -
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 ... -
Nanotwinned fcc metals: Strengthening versus softening mechanisms
(American Physical Society, 2010-12-01)The strengthening effect of twins in nanocrystalline metals has been reported both in experiment and simulation. While twins are mostly considered as effective barriers to dislocation slip transfer, they can also provide ... -
Native Backfill Materials for Mechanically Stabilized Earth Walls
(Virginia Center for Transportation Innovation and Research, 2005-04-01)Mechanically stabilized earth walls are an attractive alternative to conventional reinforced concrete retaining walls. The economy of these walls for non-critical applications might be improved by using alternative backfills ... -
Natural Categories for More Natural Generation
(Department of Computer Science, Virginia Polytechnic Institute & State University, 1990), TR-90-22Psychological research has shown that natural taxonomies contain a distinguished or basic level. Adult speakers use the names of these categories most frequently and can list a large number of attributes for them. They ... -
Natural frequencies of curved elastic arcs
(Acoustical Society of America, 1978-12-01)A perturbation analysis is presented for calculating the inextensional natural frequencies of curved elastic arcs. Variation of the radius of curvature along the arc length is accounted for by considering the curvature to ... -
Natural Language Toolkit (NLTK)
(2010-10-25)This module is a teaching and studying platform for prototyping and building research systems on natural language processing (NLP), related to linguistics, cognitive science, artificial intelligence, information retrieval, ... -
Natural, incidental, and engineered nanomaterials and their impacts on the Earth system
(2019-03-29)Nanomaterials are critical components in the Earth system's past, present, and future characteristics and behavior. They have been present since Earth's origin in great abundance. Life, from the earliest cells to modern ... -
Nature-Inspired Hierarchical Steels
