On-surface Synthesis of a Chiral Graphene Nanoribbon with Mixed Edge Structure.
2020
Abstract Chiral graphene nanoribbons represent an important class of graphene nanomaterials with varying combinations of armchair and zigzag edges conferring them unique structure‐dependent electronic properties. Here, we describe the on‐surface synthesis of an unprecedented cove‐edge chiral GNR with a benzo‐fused backbone on a Au(111) surface using 2,6‐dibromo‐1,5‐diphenylnaphthalene as precursor. The initial precursor self‐assembly and the formation of the chiral GNRs upon annealing are revealed, along with a relatively small electronic bandgap of approximately 1.6 eV, by scanning tunnelling microscopy and spectroscopy.
Chemical Vapor Deposition Synthesis and Terahertz Photoconductivity of Low-Band-Gap N = 9 Armchair Graphene Nanoribbons.
2017
Recent advances in bottom-up synthesis of atomically defined graphene nanoribbons (GNRs) with various microstructures and properties have demonstrated their promise in electronic and optoelectronic devices. Here we synthesized N = 9 armchair graphene nanoribbons (9-AGNRs) with a low optical band gap of ∼1.0 eV and extended absorption into the infrared range by an efficient chemical vapor deposition process. Time-resolved terahertz spectroscopy was employed to characterize the photoconductivity in 9-AGNRs and revealed their high intrinsic charge-carrier mobility of approximately 350 cm2·V-1·s-1.

Migration, Identity, and Threatened Mental Health: Examples from Contemporary Fiction.
2018
In 2015, the world saw 244 million international migrants. Migration has been shown to be both a protective and a risk factor for mental health, depending on circumstances. Furthermore, culture has an impact on perceptions and constructions of mental illness and identity, both of which can be challenged through migration. Using a qualitative research approach, we analysed five internationally acclaimed and influential novels and one theatre play that focus on aspects of identity, migration, and threatened mental health. As a mirror of society, fiction can help to understand perceptions of identity and mental suffering on an intrapsychic and societal level, while at the same time society its…
An Analysis of the Presence and Composition of OutLists at United States, Canadian, and European Medical Institutions
2019
Sexual and gender minority (SGM) medical students and physicians are exposed to bias in professional contexts. One strategy for promoting SGM visibility and inclusion within medicine is the development of institutional OutLists, which are online, opt-in lists of SGM-identified individuals affiliated with an academic institution. We present the first quantitative evaluation of publicly accessible OutLists at medical institutions in the United States, Canada, and Europe. Nineteen OutLists were identified in the United States; no OutLists were identified in other countries. All OutLists in the United States were identified at allopathic institutions with no institutional religious affiliation.…
Biopiracy and the right to self-determination of indigenous peoples.
2018
Abstract Background: Since over thirty years, I work on the unclear legal situation of in which indigenous peoples find themselves today in the beginning mainly in the USA and later also in Canada, Australia and New Zealand. The status of indigenous people and native nations is characterized as a mixture of national and international law. Hypothesis/Purpose: To clarify the status of indigenous people it is necessary to analyze and interpret carefully hundreds of old treaties, international declarations and covenants, national statutes and jurisprudence, especially the old leading decisions of the US-Supreme Court. Such an analysis and interpretation should prove that indigenous people have …
Il cappero: analisi desk sui flussi di commercializzazione in Italia e nei principali Paesi competitors
2009
In questi ultimi anni, il commercio di cappero, a livello internazionale, ha fatto registrare un trend positivo rappresentato da uno scambio di prodotto pari, secondo dati forniti dal COMTRADE, a circa 3 mila tonnellate. A fronte di tali incrementi, in Italia, la superficie investita a cappero è scesa drasticamente, passando da circa 1000 ha nel ’83 a circa 170 ha nel 2006. Ciò, presumibilmente, è dovuto alla carente attuazione di sapienti strategie di marketing sul prodotto cappero da parte degli imprenditori agricoli. In quest’ottica, nell’ambito del progetto “IL CAPPERO DELLE ISOLE MINORI”, è stata avviata una ricerca con lo scopo di elaborare un piano strategico di rilancio del comparto…
Late Carnian-Early Norian ammonoids from the GSSP candidate section Pizzo Mondello (Sicani mountain, Sicily).
2012
A small collection of ammonoids from the Upper Triassic Scillato Formation at Pizzo Mondello (Agrigento, Sicily) is studied. The specimens were collected in a framework of a project aimed at providing an integrated high-resolution bio-chronostratigraphic support to the Upper Carnian-Norian magnetostratigraphic scale defined at this site, that is located in an historical area from which G.G. Gemmellaro collected the Upper Triassic of ammonoids monographed at the beginning of the XX century. The specimens from Pizzo Mondello were bed-by-bed sampled and represent the first collection of Upper Triassic ammonoids described from Sicily since Gemmellaro time. Quite several levels of the Pizzo Mond…
Il margine del parco agricolo del torrente San Vincenzo su corso Italia, Carini
2014
Sui rilievi a ovest di Palermo, ai piedi di Monte Saraceno e Monte Ceresia, circondato dai monti Pecoraro, Montagna Longa, Tre Pizzi, Colombrina, si sviluppa, su unʼaltura a 181 metri dal livello del mare, il nucleo di Carini. Il territorio, inciso in direzione sud-nord da alcuni collegamenti, tra cui quello di corso Italia, si estende, attraversato dalla linea ferrata e dalla statale 113, sino al golfo omonimo. Lungo la fascia a ovest dellʼabitato (di circa 100 ha) tra agrumeti, frutteti, uliveti, aree semi-coltivate o abbandonate, si può individuare una zona (di circa 240 ha), attraversata dal torrente San Vincenzo. La ferrovia (a nord), corso Italia (a est), la Rocca del Castello con le …
