Nell'ambito di uno studio realizzato in collaborazione tra due diversi istituti del CNR, ricercatori hanno sviluppato nuovi nanomateriali in oro con straordinarie capacità di trasmissione. La ricerca è stata pubblicata in ACS Nano (Impact Factor 13.942), una delle riviste più importanti e prestigiose al mondo nel settore delle nanotecnologie. La ricerca è stata condotta dal team CNR-Nanotec coordinato da Antonio De Luca in collaborazione con il team dell'ISASI-CNR coordinato da Lucia Petti ...

The Institute of Cybernetics" E Caianiello" has developed a digital holographic microscope for quantitative imaging of biostructures. A digital holographic microscope relies on the classical principle of holography except that the hologram is not recorded by a traditional film, but by means of a CCD array sensor camera, typically a sensor of 1024 x 1024 pixel of 5-10 micron size. Each pixel records the intensity of the resulting interference pattern. The hologram is recorded and digitized ...

L'Istituto di Cibernetica "E. Caianiello" nell'ambito del centro di competenza della Regione Campania sulla valorizzazione e conservazione dei Beni Culturali e Ambientali (INNOVA), ha acquisito e sviluppato un sistema prototipale di microscopia magnetica a scansione, Esso impiega un singolo sensore SQUID (Superconducting Quantum Interference Devices) operante in azoto liquido, caratterizzato da una sensibilità di circa 20 pT/Hz1/2 e una risoluzione spaziale di circa 50 ?m. Il sistema opera in ...

High-speed single-photon counting detectors have many applications, including optical communications, quantum information, spectroscopy of ultrafast quantum phenomena in biology and solid-state physics, semiconductor processing. Of particular interest would be a detector that exhibits both ultrafast count rates ≥ GHz and high single-photon detection efficiency at near-infrared wavelengths (1550 nm); however, this combination is not available with current technologies. InGaAs avalanche ...

L'Istituto di Cibernetica ha progettato e realizzato gradiometri SQUID (Superconducting Quantum Interference Device) per microscopia magnetica a scansione. Tali dispositivi [1], basati sulla tecnologia del niobio, sono del tipo a gradiometro asimmetrico; hanno una micro bobina di pick-up integrata, con diametro interno di 5 micron, alla distanza di circa 50 mm dallo SQUID. Nel micro pick-up è anche possibile inviare una corrente in modo da poter applicare un campo magnetico al campione in ...

For the modern information systems there an increased interest to explicitly represent the underlying conceptual layer. In this contest a reach bag of software tools have been developed to aggregate and manage the information in conceptual packaging structures (Octapy Framework), structure to render in a graphic mode. The graphic visualization is chosen in a such a way that it is possible to associate the action corresponding to the user interaction (Visual Interaction Module -IGM). The ...

The SQUID (acronym of Superconducting Quantum Inteference Device) is one of the most important devices in the framework of the "small scale" applications of Superconductivity. It is based on the magnetic flux quantisation in a superconducting ring and on the Josephson Effect. In magnetometer configuration, a SQUID is the most sensitive detector of magnetic field; it is able to measure a magnetic field of the order of some billions times smaller than the earth magnetic field. SQUID magnetometers ...

There is a prevailing hypothesis that multiple sclerosis (MS) is a polygenic immune-mediated disease. So far only one genetic factor has been identified located in human leukocyte antigen (HLA) class II, specifically DR15, DQ6. However, there is no convincing evidence of a common susceptibility locus. We have identified a pedigree of Pennsylvania Dutch extraction, in which MS segregates with an autosomal dominant inheritance pattern. We have collected blood samples from 18 family members, seven ...

An important goal has been reached regarding shape representation with reduced dimensionality for three-dimensional objects (refer to "Curve skeletonization of surface-like objects in 3D images guided by voxel classification", S. Svensson, I. Nyström, G. Sanniti di Baja, Pattern Recognition Letters, 23/12 1419-1426, 2002). It is well-known that skeletonization is a process to extract from a two-dimensional object a set of arcs and curves, called skeleton, that is a sketched and faithful ...
