Study on the bio-functionalization of memristive nanowires for optimum memristive biosensors

Giovanni De Micheli, Sandro Carrara, Irene Taurino, Ioulia Tzouvadaki

Semiconductor nanowires are emerging as promising building blocks for biosensors enabling direct electrical detection of various biomolecules. In this framework, two-terminal Schottky-barrier silicon (Si) nanowire arrays that exhibit memristive electrical ...

Basal body structure in Trichonympha

Pierre Gönczy, Paul Guichard

Trichonympha is a symbiotic flagellate of many species of termites and of the wood-feeding cockroach. Remarkably, this unicellular organism harbors up to over ten thousand flagella on its surface, which serve to propel it through the viscous environment of ...

Polarity of translation boundaries in antiferroelectric PbZrO3

Nava Setter, Xiankui Wei

The polarity of translation boundaries (TBs) in antiferroelectric PbZrO3 is investigated. We show that previous experimentally reported polar property of RIII-1 type TB can be well approximated by a strain-free rigid model. Based on this, the modeling inve ...

Direct Evidence of Surface Reduction in Monoclinic BiVO4

Cécile Hébert, Daniele Passerone, Rolf Erni, Piyush Agrawal

Local measurements of the oxidation state of vanadium in monoclinic BiVO4 particles by means of electron energy-loss spectroscopy in scanning transmission electron microscopy reveal a pronounced surface reduction: within a 5-nm-thick shell, the oxidation s ...

Electron-Phonon Interactions and the Intrinsic Electrical Resistivity of Graphene

Nicola Marzari, Boris Kozinsky, Thibault Daniel Pierre Sohier

We present a first-principles study of the temperature- and density-dependent intrinsic electrical resistivity of graphene. We use density-functional theory and density-functional perturbation theory together with very accurate Wannier interpolations to co ...

Atomic force and electron microscopic-based study of sarcolemmal surface of living cardiomyocytes unveils unexpected mitochondrial shift in heart failure

Sandor Kasas

Loss of T-tubules (TT), sarcolemmal invaginations of cardiomyocytes (CMs), was recently identified as a general heart failure (HF) hallmark. However, whether IT per se or the overall sarcolemma is altered during HF process is still unknown. In this study, ...

Oxidation mechanism of nickel particles studied in an environmental transmission electron microscope

Jan Van Herle, Cécile Hébert, Aïcha Hessler-Wyser, Quentin Thomas Jeangros

The oxidation of nickel particles was studied in situ in an environmental transmission electron microscope in 3.2 mbar of O-2 between ambient temperature and 600 degrees C. Several different transmission electron microscopy imaging techniques, electron dif ...
