Nanoscale NMR spectroscopy and imaging of multiple nuclear species
(Nature Publishing Group, 2015)Nuclear magnetic resonance (NMR) spectroscopy and magnetic resonance imaging (MRI) provide non-invasive information about multiple nuclear species in bulk matter, with wide-ranging applications from basic physics and ... -
Nanoscale Surface Element Identification and Dopant Homogeneity in the High-\(T_c\) Superconductor \(Pr_xC_{1-x}Fe_2As_2\)
(American Physical Society, 2013)We use scanning tunneling microscopy to determine the surface structure and dopant distribution in \(Pr_xCa_{1-x}Fe_2As_2\), the highest-\(T_c\) member of the 122 family of iron-based superconductors. We identify the cleaved ... -

(American Physical Society (APS), 2013)We use scanning tunneling microscopy to determine the surface structure and dopant distribution in PrxCa1−xFe2As2, the highest-Tc member of the 122 family of iron-based superconductors. We identify the cleaved surface ... -
Nanoscale Volcanoes: Accretion of Matter at Ion-Sculpted Nanopores
(American Physical Society (APS), 2006)We demonstrate the formation of nanoscale volcanolike structures induced by ion-beam irradiation of nanoscale pores in freestanding silicon nitride membranes. Accreted matter is delivered to the volcanoes from micrometer ... -
Nanoscience and the nano-bioelectronics frontier
(Springer Science + Business Media, 2015)This review describes work presented in the 2014 inaugural Tsinghua University Press-Springer Nano Research Award lecture, as well as current and future opportunities for nanoscience research at the interface with brain ... -
Nanoshells as a high-pressure gauge analyzed to 200 GPa
(AIP Publishing, 2011)In this article, we present calculations that indicate that nanoshells can be used as a high-pressure gauge in diamond anvil cells (DACs). Nanoparticles have important advantages in comparison with the currently used ruby ... -
Nanoskiving Core–Shell Nanowires: A New Fabrication Method for Nano-optics
(American Chemical Society (ACS), 2014)This paper describes the fabrication of functional optical devices by sectioning quantum-dotin-nanowires systems with predefined lengths and orientations. This fabrication process requires only two steps: embedding the ... -

Nanowire Biosensors for Label-Free, Real-Time, Ultrasensitive Protein Detection
(Humana Press, 2011)Sensitive and quantitative analysis of proteins is central to disease diagnosis, drug screening, and proteomic studies. Among recent research advances exploiting new nanomaterials for biomolecule analysis, silicon nanowires ... -
Nanowire electrodes for high-density stimulation and measurement of neural circuits
(Frontiers Media S.A., 2013)Brain-machine interfaces (BMIs) that can precisely monitor and control neural activity will likely require new hardware with improved resolution and specificity. New nanofabricated electrodes with feature sizes and densities ... -
Nanowire nanocomputer as a finite-state machine
(Proceedings of the National Academy of Sciences, 2014)Implementation of complex computer circuits assembled from the bottom up and integrated on the nanometer scale has long been a goal of electronics research. It requires a design and fabrication strategy that can address ... -
Nanowire nanoelectronics: Building interfaces with tissue and cells at the natural scale of biology
(Walter de Gruyter GmbH, 2013)The interface between nanoscale electronic devices and biological systems enables interactions at length scales natural to biology, and thus should maximize communication between these two diverse yet complementary systems. ... -
Nanowire transistor arrays for mapping neural circuits in acute brain slices
(Proceedings of the National Academy of Sciences, 2010)Revealing the functional connectivity in natural neuronal networks is central to understanding circuits in the brain. Here, we show that silicon nanowire field-effect transistor (Si NWFET) arrays fabricated on transparent ... -
