Optical Properties of III-V Nanowires and Their Application for Charge Transport and Single-Photon Emission

2012

This work covers the optical characterization of III-V semiconductor nanowires and their application for charge transport and for single-photon emission. InAs nanowires have been investigated by Raman scattering and PL spectroscopy. The possibility to grow nanowires with a crystal structure different from its bulk counterpart has aroused a lot of interest in their optical and electronic properties. Here, the optical phonon modes of wurtzite InAs nanowires have been studied by polarized Raman scattering. For the first time, Raman measurements on a single InAs nanowire have revealed the A1(TO) and E2h optical phonon modes of the wurtzite structure. Additional resonant Raman scattering experim…

Nuclear structure and neutrino-nucleus reactions at supernova energies

2015

Supernova-(anti-)neutrino–nucleus scattering is discussed with reference to neutral-current (NC) and charged-current (CC) processes in heavy stable nuclei. The Donnelly-Walecka method with the associated multipole expansion of the nucleonic current has been adopted as the basic framework in deriving the neutrino-nucleus scattering cross sections. The needed nuclear wave functions are computed by using the quasiparticle random-phase approximation (QRPA) for the even-even target nuclei in the NC processes and the proton-neutron QRPA (pnQRPA) has been used to compute the CC processes for the mentioned nuclei. The wave functions of the stable odd-mass target nuclei have been obtained by the use…

Shape staggering of midshell mercury isotopes from in-source laser spectroscopy compared with density-functional-theory and Monte Carlo shell-model c…

2019

Neutron-deficient Hg177-185 isotopes were studied using in-source laser resonance-ionization spectroscopy at the CERN-ISOLDE radioactive ion-beam facility in an experiment combining different detection methods tailored to the studied isotopes. These include either α-decay tagging or multireflection time-of-flight gating for isotope identification. The endpoint of the odd-even nuclear shape staggering in mercury was observed directly by measuring for the first time the isotope shifts and hyperfine structures of Hg177-180. Changes in the mean-square charge radii for all mentioned isotopes, magnetic dipole, and electric quadrupole moments of the odd-A isotopes and arguments in favor of I=7/2 s…

Nuclear moments and charge radii of neutron-deficient francium isotopes and isomers

2015

Collinear laser fluorescence spectroscopy has been performed on the ground and isomeric states of 204,206Fr in order to determine their spins, nuclear moments, and changes in mean-squared charge radii. A new experimental technique has been developed as part of this work which much enhances the data collection rate while maintaining the high resolution. This has permitted the extension of this study to the two isomeric states in each nucleus. The investigation of nuclear g factors and mean-squared charge radii indicates that the neutron-deficient Fr isotopes lie in a transitional region from spherical towards more collective structures. peerReviewed

Il responsabile del procedimento rivisitato

2021

Thirty years after the enactment of law no. 241/1990 the person in charge of the procedure remains the most innovative and characterizing part of the Italian experience and, at the same time, the one that has received little, if not very little, attention from the doctrine. The essay intends to provide an examination of the problematic elements deriving from the interrelation between the organizational aspects of the figure and the tasks reserved to the management. In particular, it analyzes the decision-making and personal responsibility space that falls on the official responsible for the procedure. The argument given is that the person in charge of the procedure configures a hypothesis o…

Aineisto artikkeliin 'Monitoring organizational Article Processing Charges (APCs) using external sources: case Turku University Library'

2022

Aineisto koostuu Turun yliopiston ja Turun yliopistollisen sairaalan vertaisarvioitujen julkaisujen kirjoittajamaksutiedoista eli APC-maksutiedoista vuosilta 2017-2108 sekä vertailuaineistosta, joka haettiin ulkoisista lähteistä (Web of Science, Scopus, Unpaywall). Aineiston tarkoitus on mahdollistaa vertailu organisaation sisäisen kirjoittajamaksukirjanpidon ja ulkoisista lähteistä saatavilla olevan kirjoittajamaksuja koskevan informaation välillä. Aineiston analyysin tavoitteena oli selvittää, miten iso osa organisaation maksamista kirjoittajamaksuista sisältyy sisäiseen kirjanpitoon, ja mikä osa jää kirjanpidon ulkopuolelle. The dataset contains analysis of organizational APC monitoring …

Safety of hospital discharge before return of bowel function after elective colorectal surgery

2020

Ileus is common after colorectal surgery and is associated with an increased risk of postoperative complications. Identifying features of normal bowel recovery and the appropriateness for hospital discharge is challenging. This study explored the safety of hospital discharge before the return of bowel function.A prospective, multicentre cohort study was undertaken across an international collaborative network. Adult patients undergoing elective colorectal resection between January and April 2018 were included. The main outcome of interest was readmission to hospital within 30 days of surgery. The impact of discharge timing according to the return of bowel function was explored using multiva…

New charge transfer salts of two organic π-donors of the tetrathiafulvalene type with the paramagnetic [Cr(NCS)6]3- anion

2003

cited By 9; International audience; The electrochemical combination of the paramagnetic anion [Cr(NCS)6]3- with the organic π-donors bis(ethylenedithio)tetrathiafulvalene (ET) and 4,5-bis(2-hydroxyethylthio) -4′,5′-ethylenedithiotetrathiafulvalene (DHET-EDTTTF) leads to two new radical cation salts, namely (ET)4 [Cr(NCS 6]·PhCN 1 and (DHET-EDTTTF)2 (NEt4)[Cr(NCS)6] 2. Both have been characterized by X-ray crystallography, magnetic and resistivity measurements. The structure of 1 consists of alternating inorganic layers generated by the anions and organic layers in which the PhCN molecules are inserted; the organic sub-lattice is built up from four different ET units, three of them with a ch…
