Self-Assembled Monolayers (SAMs) in Organic Field-Effect Transistors

Leonardi, Francesca <1986> 09 April 2014 (has links)
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.

Design and fabrication of biocompatible scaffolds for the regeneration of tissues

Barbalinardo, Marianna <1981> 09 April 2014 (has links)
Regenerative medicine and tissue engineering attempt to repair or improve the biological functions of tissues that have been damaged or have ceased to perform their role through three main components: a biocompatible scaffold, cellular component and bioactive molecules. Nanotechnology provide a toolbox of innovative scaffold fabrication procedures in regenerative medicine. In fact, nanotechnology, using manufacturing techniques such as conventional and unconventional lithography, allows fabricating supports with different geometries and sizes as well as displaying physical chemical properties tunable over different length scales. Soft lithography techniques allow to functionalize the support by specific molecules that promote adhesion and control the growth of cells. Understanding cell response to scaffold, and viceversa, is a key issue; here we show our investigation of the essential features required for improving the cell-surface interaction over different scale lengths. The main goal of this thesis has been to devise a nanotechnology-based strategy for the fabrication of scaffolds for tissue regeneration. We made four types of scaffolds, which are able to accurately control cell adhesion and proliferation. For each scaffold, we chose properly designed materials, fabrication and characterization techniques.

Nano-fabrication of complex functional structures using non- conventional lithography

Hemmatian, Zahra <1980> 09 April 2014 (has links)
In Chapter 1 I will present a brief introduction on the state of art of nanotechnologies, nanofabrication techniques and unconventional lithography as a technique to fabricate the novel electronic device as resistive switch so-called memristor is shown. In Chapter 2 a detailed description of the main fabrication and characterization techniques employed in this work is reported. Chapter 3 parallel local oxidation lithography (pLOx) describes as a main technique to obtain accurate patterning process. All the effective parameters has been studied and the optimized condition observed to highly reproducible with excellent patterned nanostructures. The effect of negative bias, calls local reduction (LR) studied. Moreover, the use of AC bias shows faster patterning process respect to DC bias. In Chapter 4 (metal/ e-SiO2/ Si nanojunction) it is shown how the electrochemical oxide nanostructures by using pLOx can be used in the fabrication of novel devices call memristor. We demonstrate a new concept, based on conventional materials, where the lifetime problem is resolved by introducing a “regeneration” step, which restores the nano-memristor to its pristine condition by applying an appropriate voltage cycle. In Chapter 5 (Graphene/ e-SiO2/ Si), Graphene as a building block material is used as an electrode to selectively oxidize the silicon substrate by pLOx set up for the fabrication of novel resistive switch device. In Chapter 6 (surface architecture) I will show another application of pLOx in biotechnology is shown. So the surface functionalization combine with nano-patterning by pLOx used to design a new surface to accurately bind biomolecules with the possibility of studying those properties and more application in nano-bio device fabrication. So, in order to obtain biochips, electronic and optical/photonics devices Nano patterning of DNA used as scaffolds to fabricate small functional nano-components.

"Il carceriere di sé medesimo" di Lodovico Adimari e Alessandro Melani, Firenze 1681. Dalla «comedia» di Pedro Calderón de la Barca al «drama per musica» italiano di fine Seicento / "Il carceriere di sé medesimo" by Lodovico Adimari and Alessandro Melani, Florence 1681. From the «comedia» of Pedro Calderón de la Barca to the «drama per musica» in Late Seventeenth Century Italy

Usula, Nicola <1983> 23 June 2014 (has links)
Questo lavoro è imperniato sullo studio di uno dei melodrammi più interessanti della fine del XVII secolo: “Il carceriere di sé medesimo” di Lodovico Adimari (1644-1708) e Alessandro Melani (1639-1703), allestito per la prima volta a Firenze nel 1681, e ripreso nel giro di una ventina d’anni a Reggio (1684), a Bologna (1697) e a Vienna (1702). L’opera vanta un’origine drammatica di spicco: risale infatti alla commedia “Guardarse a sí mismo” di Pedro Calderón de la Barca (1600-1681) mediata dal “Geôlier de soi-mesme” di Thomas Corneille (1625-1709), e presenta qualità poetiche e musicali evidenti, assicurate dai nomi del poeta Lodovico Adimari e del compositore Alessandro Melani. A ciò si aggiungano una tradizione articolata in quattro allestimenti, nonché un elevato numero di testimoni superstiti: cinque edizioni del libretto (testimoniate da numerosi esemplari) e il numero fortunatissimo di tre partiture manoscritte, conservate a Parigi, Bologna e Modena. La tesi contiene l’edizione critica del “Carceriere di sé medesimo” di Adimari con tutte le varianti accumulatesi nella riedizione del libretto e nella copiatura della partitura, l’analisi del dramma, a partire dal confronto tra i testi di Calderón, Corneille e Adimari, e lo studio delle sue componenti drammatiche, formali e contenutistiche. Si aggiunge uno studio sul contesto storico-musicale degli allestimenti di Firenze, Reggio, Bologna e Vienna, nonché l’edizione dei restanti tre drammi di Adimari: la commedia “Le gare dell’amore e dell’amicizia” (1679), e il dramma per musica “L’amante di sua figlia” (1684). / This study concerns one of the most interesting Italian operas of the late seventeenth century: “Il carceriere di sé medesimo” by Lodovico Adimari (1644-1708) and Alessandro Melani (1639-1703), staged for the first time in Florence in 1681, and renewed some years later in Reggio (1684), Bologna (1697) and Vienna (1702). This opera has noble dramatic roots since it descends from the «comedia» “El guardarse a sí mismo” by Pedro Calderón de la Barca (1600-1681), translated in French as “Le geôlier de soi-mesme” by Thomas Corneille (1625-1709), and it presents high poetic and musical qualities, as the names of Adimari and Melani can guarantee. A number of sources of this opera survives: 4 editions of the libretto and three manuscript scores (held in Paris, Bologna and Modena). In addition to the study of the historical context in which the opera has been performed in 1681, 1684, 1697 and 1702, this dissertation contains a critical edition of the libretto of “Il carceriere di sé medesimo” and two other plays written by Adimari: “Le gare dell’amore e dell’amicizia” (1679), and “L’amante di sua figlia” (1684).
