Abstract

In this paper, we discuss the surface doping in sexithiophene (T6) organic field-effect transistors by PDI-8CN2. We show that an accumulation heterojunction is formed at the interface between the organic semiconductors and that the consequent band bending in T6 caused by PDI-8CN2 deposition can be addressed as the cause of the surface doping in T6 transistors. Several evidences of this phenomenon have been furnished both by electrical transport and photoemission measurements, namely the increase in the conductivity, the shift of the threshold voltage and the shift of the T6 HOMO peak towards higher binding energies., Comment: 5 pages, 5 figures

Abstract

In this paper, the dynamics of bias stress phenomenon in Sexithiophene (T6) Field Effect Transistors (FETs) has been investigated. T6 FETs have been fabricated by vacuum depositing films with thickness from 10 nm to 130 nm on Si/SiO2 substrates. After the T6 film structural analysis by X-Ray diffraction and the FET electrical investigation focused on carrier mobility evaluation, bias stress instability parameters have been estimated and discussed in the context of existing models. By increasing the film thickness, a clear correlation between the stress parameters and the structural properties of the organic layer has been highlighted. Conversely, the mobility values result almost thickness independent.

Abstract

“Composizione-Superficie Lunare” (1965) is an artwork of the Italian artist Giulio Turcato (Mantua, 1912- Rome, 1995). This painting, inspired by moon travels, was created on a polyurethane foam support, material experimentalized by some other contemporary artists in the late 1960′s. In the present paper the organic and inorganic materials used as binders, fillers and pigments, as well as the support itself, have been investigated by means of a multi-analytical approach based on the application of Environmental Scanning Electron Microscopy Energy-Dispersive X-ray spectroscopy (ESEM–EDX), Micro-Attenuated Total Reflection Fourier Transform Infrared spectroscopy (µ-ATR–FTIR), High Performance Liquid Chromatography coupled with Diode Array Dectector and tandem Mass Spectrometry (HPLC–DAD, LC–MS/MS), Pyrolysis-Gas Chromatography and Evolved Gas Analysis coupled with Mass Spectrometry (Py-GC/MS, multi-shot Py-GC/MS and EGA–MS). The plethora of analytical techniques available allowed to provide for the first time a full characterization of the different materials used in “Composizione-Superficie Lunare” and of a Turcato's painting. The polyurethane foam artwork was painted using synthetic inorganic and organic pigments, such as methyl violet and manganese violet, dispersed in polyvinyl acetate as medium. The study was fundamental for establishing the original materials and aesthetics of the artwork as well as assessing the degradation state of the painting materials and of the polyurethane foam support. The results collected, crucial for planning an effective restoration campaign, highlight the importance of the contribution of analytical chemistry to cultural heritage.

Abstract

The Fundamental Review of the Trading Book (FRTB) introduces changes in capital requirements as a consequence of changes in the calculation of risk weighted assets (RWAs), as agreed in the Basel Committee on Banking Supervision. This report performs an ex-ante assessment of the benefits of this new legislative proposal and is included as an annex to the Impact Assessment of the Capital Requirement Regulation II (CRR II).The analysis is conducted by estimating the required variation in banks’ capital following the implementation of the legislative changes by using econometric and statistical techniques. The estimated capital requirements are then used to feed a simulation model of losses originating from the banking sector in the event of a banking crisis. Results of the crisis simulation before and after the introduction of the legislative changes are compared to arrive at an estimation of the impacts. Benefits are measured as reduction in banks’ losses that need to be absorbed by different stakeholders, starting from shareholders and including the whole loss absorption cascade and financial safety net (i.e. bail-in and resolution funds). The main conclusions are:1. If one ignores the leverage ratio (LR) requirement and only focusses on the impact of the FRTB, results are the following:a. When assuming banks’ capital equal to the minimum capital requirement (MCR), the implementation of the FRTB implies higher capitalization levels/needs due to higher RWAs. The estimated reduction in potential public finance contingent liabilities from the banking sector in case of a crisis similar to the last one is of 15%. b. However, when considering the excess capital buffers which the vast majority of banks have set aside over the last few years, the implementation of the FRTB does not imply additional capital needs to meet the increased requirements and does not reduce potential contingent liabilities from the banking sector compared to the status quo. In fact, if buffers are n

Abstract

The setting up of the ARGO detector at the YangBaJing Cosmic Ray Laboratory (4300 m a.s.l., Tibet, P.R. China) has been completed during the last spring (2007). It consists of a central carpet made of 130 identical sub-units of 12 RPCs each (a "cluster"), covering a surface of about 5800 m2 with 93% active area, and a guard ring of 24 further clusters of the same type surrounding the central carpet with a lower sampling density. Signals are picked up by external electrodes of small size, thus allowing the sampling of EAS with high space-time granularity. Shower events are detected at a trigger rate of about 4 kHz. Events with a few particles detected by a single cluster are counted in scaler mode on a time base of 500 ms. The intrinsic modularity of the ARGO detector allowed us to collect data even during the setting-up period, using only the central carpet (or even part of it). Some preliminary results from the analysis of events collected in a few months of data taking are presented. © 2008 Elsevier B.V. All rights reserved.

Abstract

Following the completion of the 5700m 2 RPC carpet-like AS array at YangBaJing this year, a further plan based on the ARGO Carpet is raised. It characterizes with its high altitude site, its full-coverage detector array and the multi-parameter measurements. Apart from studies on TeV and sub-TeV energy range, UHE Gamma-ray sources and the Knee Physics will become its characteristic subjects. In the first phase of the plan, the Yangbajing Super Complex Array (YSCA) will include a 10 4 m 2 RPC Carpet, five indoor μ -detectors (∼170 m 2 each), four big outdoor μ -detectors (∼432 m 2 each) and a traditional field scintillation detector array surrounding the Carpet. Monte-Carlo study shows that, with such an array in YBJ (4300m a.s.l.), γ -ray induced air showers can be separated from proton induced air showers clearly using only the observed electron and μ data event by event. To assist the classification of UHE air showers induced by different primary nuclei groups without severe interference by Composition/Model Entanglement, a second phase plan having a Central Burst Detector Array (CBDA) and some pulse shape detectors is schemed.

Abstract

The possibility of the fabrication of organic devices suitable to be applied in bio-sensing fields depends largely on the availability of organic compounds displaying robust electrical properties even in aqueous solutions and effective biocompatibility features. In this paper, we report about the good cellular biocompatibility and the electrical response stability in an ionic medium of n-type organic transistors based on the recently developed PDI-8CN2 oligomer. The biocompatibility has been tested by analyzing the adhesion and viability of two different cell lines, human epithelial HeLa cells and murine neuronal F11 cells, on PDI-8CN2 films grown by organic molecular beam deposition (OMBD) on SiO2 substrates. The effect of film thickness on cell attachment was also tested. Uncoated SiO2 substrates were used as control surfaces and sexithiophene (T6) as device testing control. Moreover, the possible toxicity of -CN groups of PDI-8CN2 was tested on HeLa cell cultures, using PDI-8 and T6 molecules as controls. Results showed that, although at high concentration these organic compounds are toxic in solution, if they are presented in form of film, cell lines can attach and grow on them. The electrical response stability of PDI-8CN2 transistors in a cellular culture medium characterized by high concentrations of ionic species has been also investigated. For this purpose, low-voltage operation devices with VGS ranging from -5 V to 5 V, able to strongly reduce the influence of Faradaic currents coming from the electrical operation in an highly ionic environment, have been fabricated on 35 nm thick SiO2 layers and electrically characterized. These results are useful to experimentally define the main critical issues to be further addressed for the fabrication of reliable bio-sensors based on organic transistors. [ABSTRACT FROM AUTHOR]

Abstract

In this paper, the bias stress effect (BSE) in organic field-effect transistors has been analyzed by an alternative experimental approach based on ac admittance (Y=G+jωC) measurements. conductance (C) and capacitance (G) curves have been recorded as a function of frequency at different times of the bias stress experiments and simultaneously fitted through a transmission line circuit, able to separately model the conducting properties of the channel and contact regions. The determination of the time behavior of the model fitting parameters is assumed as the starting point for a quantitative analysis of the BSE occurrence. This experimental procedure clarifies that both channel resistance (Rch) and contact resistance (Rc) are largely affected by the BSE, while the channel capacitance (Cch), related to the charge accumulation sheet, and the contact capacitance (Cc) result almost unchanged.

Abstract

Kerion Celsi is a parasitic fungal skin infection that tends to occur mainly on the back of the neck, scalp or beard. It is caused by animal fungi. Sometimes the condition resolves itself in a matter of weeks but hair loss in the affected area may be permanent. We report a case of a young woman with Kerion Celsi favored by the use of a tretinoin+minoxidil+betametasone valerate lotion.

Abstract

This paper reports the preliminary results obtained from the data acquired during the diagnostic survey, begun in September 2011, to evaluate the state of conservation of the mural Tuttomondo (1989) by Keith Haring (1958-1990). Multispectral imaging technique, ultra-high resolution photography, ultraviolet (UV), visible (Vis), and near infrared (NIR) Fiber Optic Reflectance Spectroscopy (FORS), colorimetry, and Pyrolysis-Gas Chromatography/Mass Spectrometry (Py-GC/MS) analysis were performed directly on the mural or on samples taken from the mural to support the conservation intervention, which was focused on cleaning and the subsequent consolidation of the painting. These analyses were carried out as part of the research project "Preventive Conservation of Contemporary Art" (COPAC). The COPAC Project is a 2-year research project (2011-2013) financially supported by the Regione Toscana (Tuscany, Italy) in the PAR-FAS program, Disciplinary Framework Science and Technology for the Safeguard and Valorisation of Cultural Heritage. The COPAC 2 Project is a joint effort of research institutions, conservators, city councils, museums, and art collections in Tuscany. COPAC activities are focused mainly on the study of the materials used by contemporary artists to produce their artworks with a twofold goal: defining artworks materials and monitoring their conservation and/or their degradation processes over time. In order to achieve this goal the research team adopted a plan based on the use of several diagnostic methodologies for the study of selected contemporary artworks belonging to museums, galleries, and collections in Tuscany. The purpose of this approach was to acquire as much data as possible about artists' materials and techniques and, also, to monitor both the state-of-conservation of the artworks and the surrounding environmental conditions (Learner, T. 2005; Chiantore, O., Rava, A. 2013). All of the collected data will be used to evaluate the conservation-state of the artworks selected for investigation and to identify their risk factors in order to select the most appropriate preservation practices. The ultimate goal of the COPAC Project is to set up an interactive archive to manage and disseminate the acquired information for the benefit of all of the curatorial and technical participants.

Abstract

The ARGO-YBJ array for EAS detection at high altitude (4300 m a.s.l.) is the largest RPC-based detector in operation at present (active area of 6700 m 2 out of a total instrumented surface of about 10 4 m 2 ). The constant monitoring of the main operational and environmental parameters is essential for both keeping the detector status under control and understanding the detector behaviour more deeply. Exploiting the information provided by the ARGO-YBJ Detector Control System, the present status of the detector is described and some correlations between the environmental and the operational parameters of the ARGO-YBJ RPCs are shown. This study was performed using the monitored data from the complete ARGO-YBJ array which has been in operation since October 2007. Preliminary results on the observations of the Moon shadow and of γ -ray point sources are also presented.

Abstract

ARGO-YBJ is the first EAS detector combining a very high mountain altitude (4300 m a.s.l.) to a "full coverage" detection surface. These features allow ARGO-YBJ to work with an energy threshold as low as a few hundreds GeV. The high duty cycle and the large field of view (~2 sr) make ARGO-YBJ suitable to monitor the gamma ray sky searching for unknown sources and unexpected events, like Active Galactic Nuclei flaring episodes or high energy Gamma Ray Bursts. In this paper we present the first observations of ARGO-YBJ concerning gamma ray astronomy, in particular the detection of the Crab Nebula and the blazar Markarian 421 during the 2006 and 2008 outbursts, and the results of a search for Gamma Ray Bursts emission in the GeV energy range using the scaler mode technique.

Abstract

We report on the search for Gamma Ray Bursts (GRBs) in the energy range 1-100 GeV in coincidence with the prompt emission detected by satellites using the Astrophysical Radiation with Ground-based Observatory at YangBaJing (ARGO-YBJ) air shower detector. Thanks to its mountain location (Yangbajing, Tibet, P.R. China, 4300 m a.s.l.), active surface (about 6700 m**2 of Resistive Plate Chambers), and large field of view (about 2 sr, limited only by the atmospheric absorption), the ARGO-YBJ air shower detector is particularly suitable for the detection of unpredictable and short duration events such as GRBs. The search is carried out using the "single particle technique", i.e. counting all the particles hitting the detector without measurement of the energy and arrival direction of the primary gamma rays. Between 2004 December 17 and 2009 April 7, 81 GRBs detected by satellites occurred within the field of view of ARGO-YBJ (zenith angle < 45 deg). It was possible to examine 62 of these for >1 GeV counterpart in the ARGO-YBJ data finding no statistically significant emission. With a lack of detected spectra in this energy range fluence upper limits are profitable, especially when the redshift is known and the correction for the extragalactic absorption can be considered. The obtained fluence upper limits reach values as low as 10**{-5} erg cm**{-2} in the 1-100 GeV energy region. Besides this individual search for a higher energy counterpart, a statistical study of the stack of all the GRBs both in time and in phase was made, looking for a common feature in the GRB high energy emission. No significant signal has been detected., Comment: accepted for publication in ApJ

Abstract

We report a case of a female patient aged 22 years affected with vulgaris ichthyosis and ectropion of the four eyelids with incomplete lid closure in both eyes and punctuate corneal staining indicating exposure in left eye. The surgical methods, consisting in skin or mucosa graft in order to reduce skin retraction, allowed the healing of the exposure keratopathy.

Abstract

In this paper, the photoexcitation response of high mobility n-type organic field-effect transistors is analyzed. White light exposure of N,N′-dioctyl-3,4,9,10-perylene tetracarboxylic diimide (PTCDI-C8H) transistors is demonstrated to promote the occurrence of metastable conductance states with very long retention times, similar to what has been previously reported for p-type compounds. Even in the absence of a gate-source voltage VGS, the complete recovery of the initial electrical condition can take up to 20 days. However, the initial state restoring is electrically controllable by the application of a positive VGS. These effects suggest that PTCDI-C8H is an interesting n-type material for the development of light-sensitive organic circuitry. [ABSTRACT FROM AUTHOR]
