On dissonance and fascist heritage in Italy. An analysis on the reuse of ex-Case del Fascio in three provinces
In Italy the current debate over the reuse of fascist heritage is, on
the one side, incapable of answering to contemporary needs and
criticalities raised by international movements and on the other
side, it is raising a growing academic interest. This research aims
to introduce critical heritage studies in the Italian context and
update the current debate over difficult heritage. Moreover, this
research enriches the interdisciplinary approach of critical
heritage studies by integrating a new perspective taken from
organisation studies.
The research focuses on the concept of dissonance linked to
difficult heritage by testing the dissonant heritage theory and
proposing a new and productive concept of dissonance. Are the
preservation of fascist heritage and the use of fascist architecture
generating dissonance? The objective is to understand how fascist
heritage is preserved and reused in Italy, how this approach has
changed over time and how it should be approached now. The
object of the research are the reuses of case del fascio (for their
capillary diffusion, representativeness of the regime, and ordinary
characteristic) in three Italian provinces (Latina, Livorno, Treviso).
The issue of the reuse, demolition or neglect of fascist-built
architectures is carried out on a twofold level: a material one,
studying the construction, modifications and reuse of case del fascio
through archival sources and on-site inspections; and a public
discourse one, applying the economies of worth by Boltanski and
Thevenot to debates over the preservation and reuse of fascist
heritage in Italy.
The innovations of the research can be found in (1) testing the
dissonant heritage theory to the Italian case, finding that the
relationship between the remains and reuse of fascist-built
architectures is not linear, is more complex and dependent on
inertia and local dynamics. It outlines also (2) a new perspective
for the critical reuse of fascist-built architectures based on a
positive concept of dissonance. An (3) analysis of how dissonance
works and how can be activated and silenced is paralleled with
suggestions on how organising dissonance as a new way of taking
decisions over the reuse of ex-fascist public buildings
Carbon-paste nanocomposites as unconventional gate electrodes for electrolyte-gated organic field-effect transistors: electrical modulation and bio-sensing
Nanocomposite carbon-paste electrodes (NC-CPEs) have been investigated for the first time in electrolytegated organic field-e¿ect transistors (EGOFETs) as a replacement of conventional metal gate electrodes, using carbon nanotubes (CNTs) as a model carbon filler. Interestingly, the electrical properties of the resulting devices have been modulated by changing the loading percentage of CNTs within the insulating polymeric matrix. The potential of using such non-conventional gate electrodes for sensing purposes has also been evaluated by investigating, as a proof of concept, the formation of a supramolecular complex between a functionalized CNT-based NC-CPE containing ß-cyclodextrin (ß-CD) as a bio-recognition element and tryptophan (TRP). This approach, in synergism with the amplification function of an EGOFET, a¿ords a shift in the threshold voltage (VTH) of the transistor, giving promising analytical results with detection limits at picomolar levels (1.0 ± 0.1 pM) as well as a linear response from 10-12 to 10-9 M. Accordingly, NC-CPEs have been demonstrated to be a potential alternative to metal gate electrodes for the development of a new generation of highly sensitive carbon-based EGOFET bio-sensorsPostprint (published version
Self-Assembled Monolayers (SAMs) in Organic Field-Effect Transistors
Organic printed electronics is attracting an ever-growing interest in the last decades because of its impressive breakthroughs concerning the chemical design of π-conjugated materials and their processing. This has an impact on novel applications, such as flexible-large-area displays, low- cost printable circuits, plastic solar cells and lab-on-a-chip devices.
The organic field-effect transistor (OFET) relies on a thin film of organic semiconductor that bridges source and drain electrodes. Since its first discovery in the 80s, intensive research activities were deployed in order to control the chemico-physical properties of these electronic devices and consequently their charge. Self-assembled monolayers (SAMs) are a versatile tool for tuning the properties of metallic, semi-conducting, and insulating surfaces. Within this context, OFETs represent reliable instruments for measuring the electrical properties of the SAMs in a Metal/SAM/OS junction.
Our experimental approach, named Charge Injection Organic-Gauge (CIOG), uses OTFT in a charge-injection controlled regime. The CIOG sensitivity has been extensively demonstrated on different homologous self-assembling molecules that differ in either chain length or in anchor/terminal group.
One of the latest applications of organic electronics is the so-called “bio-electronics” that makes use of electronic devices to encompass interests of the medical science, such as biosensors, biotransducers etc…
As a result, thee second part of this thesis deals with the realization of an electronic transducer based on an Organic Field-Effect Transistor operating in aqueous media. Here, the conventional bottom gate/bottom contact configuration is replaced by top gate architecture with the electrolyte that ensures electrical contact between the top gold electrode and the semiconductor layer. This configuration is named Electrolyte-Gated Field-Effect Transistor (EGOFET).
The functionalization of the top electrode is the sensing core of the device allowing the detection of dopamine as well as of protein biomarkers with ultra-low sensitivity
Colloque international « Le Film Français 1945-1958 : penser les évolutions d’une revue corporative »

Source incontournable pour tout chercheur qui se penche sur le cinéma en France, ce périodique, qui fête cette année ses soixante-dix ans, n’a cependant pas donné lieu jusqu’ici, à notre connaissance, à de..
Isolation of carotenoid-producing yeasts from an alpine glacier
Cold-adapted yeasts are increasingly being isolated from glacial environments, including Artic, Antarctic, and mountain glaciers. Psychrophilic yeast isolates mostly belong to Basidiomycota phylum, such as Cryptococcus, Mrakia, and Rhodotorula, and represent an understudied source of biodiversity for potential biotechnological applications. Since some basidiomycetous yeast genera (e.g. Rhodotorula, Phaffia, etc.) were demonstrated to produce commercially important carotenoids (e.g. β-carotene, torulene, torularhodin and astaxanthin), the present study aimed to obtain psychrophilic yeast isolates from the surface ice of two Italian glaciers to identify new pigment-producers. 23 yeast isolates were obtained. Among them, three isolates giving pigmented colonies was subjected to ITS1/ITS2 sequencing and were attributed to the Basidiomycetous yeasts Dioszegia sp., hodotorula mucilaginosa, and Rhodotorula laryngis. The strains were cultured batchwise in a carbon-rich medium at 15°C until the stationary phase was reached, then the pigments were extracted from freeze-dried biomass using DMSO:acetone mixture. Visible spectrum and HPLC-DAD analysis revealed the presence of carotenoid pigments. In batch cultures of Dioszegia sp., carotenoid production was growth-associated and yielded up to 3.4 mg/L of a molecule exhibiting an m/z ratio (568) consistent with the molecular weight of xanthophylls bearing 2 OH groups
Electrical release of dopamine and levodopa mediated by amphiphilic \u3b2-cyclodextrins immobilized on polycrystalline gold
Vesicles of cationic amphiphilic \u3b2-cyclodextrins have been immobilized on polycrystalline gold by exploiting the chemical affinity between their amino groups and Au atoms. The presence of cyclodextrins has been widely investigated by means of AFM, XPS, kelvin probe and electrochemical measurements. This multi-functional coating confers distinct electrochemical features such as pH-dependent behavior and partial/total blocking properties towards electro-active species. The host-guest properties of \u3b2-cyclodextrins have been successfully exploited in order to trap drugs, like dopamine and levodopa. The further release of these drugs was successfully achieved by providing specific electrical stimuli. This proof-of-concept led us to fabricate an electronic device (i.e. an organic transistor) capable of dispensing both dopamine and levodopa in aqueous solution
