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

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

Impacts of air pollution on human and ecosystem health, and implications for the National Emission Ceilings Directive. Insights from Italy

Across the 28 EU member states there were nearly half a million premature deaths in 2015 as a result of exposure to PM2.5, O3 and NO2. To set the target for air quality levels and avoid negative impacts for human and ecosystems health, the National Emission Ceilings Directive (NECD, 2016/2284/EU) sets objectives for emission reduction for SO2, NOx, NMVOCs, NH3 and PM2.5 for each Member State as percentages of reduction to be reached in 2020 and 2030 compared to the emission levels into 2005. One of the innovations of NECD is Article 9, that mentions the issue of “monitoring air pollution impacts” on ecosystems. We provide a clear picture of what is available in term of monitoring network for air pollution impacts on Italian ecosystems, summarizing what has been done to control air pollution and its effects on different ecosystems in Italy. We provide an overview of the impacts of air pollution on health of the Italian population and evaluate opportunities and implementation of Article 9 in the Italian context, as a case study beneficial for all Member States. The results showed that SO42− deposition strongly decreased in all monitoring sites in Italy over the period 1999–2017, while NO3− and NH4+ decreased more slightly. As a consequence, most of the acid-sensitive sites which underwent acidification in the 1980s partially recovered. The O3 concentration at forest sites showed a decreasing trend. Consequently, AOT40 (the metric identified to protect vegetation from ozone pollution) showed a decrease, even if values were still above the limit for forest protection (5000 ppb h−1), while PODy (flux-based metric under discussion as new European legislative standard for forest protection) showed an increase. National scale studies pointed out that PM10 and NO2 induced about 58,000 premature deaths (year 2005), due to cardiovascular and respiratory diseases. The network identified for Italy contains a good number of monitoring sites (6 for terrestrial ecosystem monitoring, 4 for water bodies monitoring and 11 for ozone impact monitoring) distributed over the territory and will produce a high number of monitored parameters for the implementation of the NECD
