(n,m)-Specific Absorption Cross Sections of Single-Walled Carbon Nanotubes Measured by Variance Spectroscopy
(2016)A new method based on variance spectroscopy has enabled the determination of absolute absorption cross sections for the first electronic transition of 12 (n,m) structural species of semiconducting single-walled carbon nanotubes (SWCNTs). Spectrally resolved measurements of fluorescence variance in dilute bulk samples provided particle number ... -
NAF-1 and mitoNEET are central to human breast cancer proliferation by maintaining mitochondrial homeostasis and promoting tumor growth
(2013)Mitochondria are emerging as important players in the transformation process of cells, maintaining the biosynthetic and energetic capacities of cancer cells and serving as one of the primary sites of apoptosis and autophagy regulation. Although several avenues of cancer therapy have focused on mitochondria, progress in developing mitochondria-targeting ... -
NaFe0.56Cu0.44As: A Pnictide Insulating Phase Induced by On-Site Coulomb Interaction
(2016)In the studies of iron pnictides, a key question is whether their bad-metal state from which the superconductivity emerges lies in close proximity with a magnetically ordered insulating phase. Recently, it was found that at low temperatures, the heavily Cu-doped NaFe1−xCuxAs (x>0.3) iron pnictide is an insulator with long-range antiferromagnetic ... -
namebrandcorporation [venture based information/technology and new media startup incubator infrastructure]
(2001)Attempts during the late twentieth century to create an office/work space containing an appropriate amount of flexibility, combined with generic specificity (to make speculative developments economically viable) have failed. High-rise workplaces no longer work [there's no room for fun and just being there is a drag]. The nature of work is changing ... -
Nano-encapsulated triggered-release viscosity breaker
(2015-06-30)A method for the encapsulation and triggered-release of water-soluble or water-dispersible materials. The method comprises a) providing an amount of electrolyte having a charge, b) providing an amount of counterion having a valence of at least 2, c) combining the polyelectrolyte and the counterion in a solution such that the polyelectrolyte self-assembles ... -
Nanoantenna-Enhanced Light-Matter Interaction in Atomically Thin WS2
(2015)Atomically thin transition metal dichalcogenides (TMDCs) are an emerging class of two-dimensional semiconductors. Recently, the first optoelectronic devices featuring photodetection as well as electroluminescence have been demonstrated using monolayer TMDCs as active material. However, the lightヨmatter coupling for atomically thin TMDCs is limited ... -
Nanocomposite oil sensors for downhole hydrocarbon detection
(2016-06-28)Various embodiments of the present disclosure pertain to nanocomposites for detecting hydrocarbons in a geological structure. In some embodiments, the nanocomposites include: a core particle; a polymer associated with the core particle; a sulfur-based moiety associated with the polymer; and a releasable probe molecule associated with the core particle, ... -
Nanocrystalline materials: recent advances in crystallographic characterization techniques
(2014)Most properties of nanocrystalline materials are shape-dependent, providing their exquisite tunability in optical, mechanical, electronic and catalytic properties. An example of the former is localized surface plasmon resonance (LSPR), the coherent oscillation of conduction electrons in metals that can be excited by the electric field of light; this ... -
Nanofibrous peptide hydrogel elicits angiogenesis and neurogenesis without drugs, proteins, or cells
(2018)The design of materials for regenerative medicine has focused on delivery of small molecule drugs, proteins, and cells to help accelerate healing. Additionally, biomaterials have been designed with covalently attached mimics of growth factors, cytokines, or key extracellular matrix components allowing the biomaterial itself to drive biological response. ... -
Nanofibrous Snake Venom Hemostat
(2015)Controlling perioperative bleeding is of critical importance to minimize hemorrhaging and fatality. Patients on anticoagulant therapy such as heparin have diminished clotting potential and are at risk for hemorrhaging. Here we describe a self-assembling nanofibrous peptide hydrogel (termed SLac) that on its own can act as a physical barrier to blood ... -
NanoJapan International Research Experience for Undergraduates: Preparing Globally Engaged Science and Engineers
(2013)The NanoJapan: International Research Experience for Undergraduates Program, established by a National Science Foundation Partnerships for International Research and Education (NSF-PIRE) grant in 2006, is a twelve-week summer program through which twelve freshman and sophomore physics and engineering students from U.S. universities complete research ... -
NanoJapan-International research experience for undergraduates program: Fostering U.S.-Japan research collaborations in terahertz science and technology of nanostructures
(2014-09-15)The international nature of science and engineering research demands that students have the skillsets necessary to collaborate internationally. However, limited options exist for science and engineering undergraduates who want to pursue research abroad. The NanoJapan International Research Experience for Undergraduates Program is an innovative response ... -
Nanoparticle comprising nanoshell of thickness less than the bulk electron mean free path of the shell material
(2008-05-13)The present invention is for particulate compositions and methods for producing them that can absorb or scatter electromagnetic radiation. The particles are homogeneous in size and are comprised of a nonconducting inner layer that is surrounded by an electrically conducting material. The ratio of the thickness of the nonconducting layer to the thickness ...
