Testo completoElectrochromic glass is a type of smart glass, a new technology that has potential to reduce the amount of sunlight entering a building by changing its physical properties. The purpose of this study is to understand the properties of electrochromic glass and determine if it is a viable alternative to conventional single pane and double pane glass in the Tucson area. Using research and statistics from smart glass production companies, a comparative analysis will be done using the building simulation software Energy-10. It was found that when compared to single pane glass, double pane glass had a decrease of 7.21% in energy cost and electrochromic glass had a decrease of 9.81%. For the used building model, this meant a return investment in 30 and a half years. While electrochromic glass is a new clean method of energy usage reduction, it currently cannot return the consumers initial investment within a desirable time span.

"Advancing approaches in glass conservation: characterisation of altered archaeological glass and artificially aged glass replicas to shed light into the mechanisms of glass corrosion". Doctoral thesis, Università degli Studi di Trieste, 2023. https://hdl.handle.net/11368/3041639.
Testo completoGlass finds application in multiple domains, from the technological to the artistic and archaeological one, and the study of its durability is crucial to determine its potential to replace several dangerous and polluting materials such as plastics, particularly now in the era of the circular economy. Because of the thermodynamic properties of glass and its high variety of compositions, the evaluation of glass durability and alteration mechanisms remains a challenge. For this reason, the study of glass corrosion is considered a complex research topic that requires the ability to take into consideration a big number of factors, some of which are hardly represented in laboratory experiments. The most influential of these is with no doubt the time given to the transformation, which is directly responsible of both the kinetics and the dynamics of the processes involved. The present PhD project aims to study the complex phenomenon of glass corrosion from the perspective of ancient glass samples, which represent unique evidence of the effect of long-lasting environmental ageing on such material. The goal is to highlight how the study of ancient and archaeological glass offers an outstanding opportunity to fill the gaps in the various theories about glass corrosion, which, in fact, have been formulated on the basis of research carried out under laboratory conditions and only partially reproducing the circumstances of environmental degradation. The ultimate purpose is twofold. On one hand, this work wants to highlight how far research on glass corrosion has come by studying model systems created in laboratory to simulate different alteration conditions and glass compositions. On the other, it wants to point out what the critical aspects that still need to be investigated are and how the study of archaeological glass may complement the results obtained over the years in research carried out on laboratory models. Archaeological glass gives indeed the unique opportunity to observe the effect of long-term natural ageing on a real material, and the results obtained from its study are key to fill the gaps that are still present in the theory of glass corrosion. This PhD thesis starts with the gathering of the results obtained about glass corrosion and its interaction with the environment, considering studies performed both on experimental and archaeological samples. The aim is to understand where the scientific today, what are the critical points that still need to be investigated and what may be the future perspective for glass preservation and applications (for instance for the development of sustainable protective treatments), to help the scientific community in the design of future, more complete, research. An innovative strategy to approach the problem of glass corrosion and its stabilisation is proposed in this work: the development of an ideal conservation treatment able to slow down the alteration process of ancient glass requires the in-depth investigation of ancient glass and of the artificially aged glass mock-ups in order to obtain a comprehensive evaluation of the modification of glass structure, its kinetic over time, and its final visible results. The information obtained from this course of the research of glass corrosion represent the basis and inspiration for a modern way of thinking about glass conservation that overcomes the limits imposed by traditional principles, such as reversibility, by exploiting the properties of cutting-edge technology such as nanotechnology.

Testo completoVidros e vitrocerâmicas fluorofosfatos dopados com íons terras raras (TR3+) estão entre os candidatos mais promissores para a geração de laser de alta eficiência na região espectral do infravermelho próximo. As vitrocerâmicas são materiais policristalinos com microestrutura bem definida obtida a partir da cristalização controlada do vidro base. Desenvolvendo vidros base de fluorofosfato com composições apropriadas e controlando a nucleação e crescimento de cristais, vitrocerâmicas com propriedades especiais podem ser fabricadas combinando as vantagens dos fluoretos (baixa energia de fônons, baixos índices de refração, janela ótica extensa, baixa higroscopicidade) e óxidos (alta estabilidade química e mecânica e alta solubilidade dopante), resultando no aumento das propriedades emissoras dos íons TR3+. Neste estudo, apresentamos a síntese por fusão/resfriamento e investigação estrutural/espectroscópica de novos vidros e vitrocerâmicas com composição 25BaF225SrF2(30-x)Al(PO3)3xAlF3(20-z)YF3: zREF3, onde x = 15, 20 ou 25, RE = Er3+ an / ou Yb3+ e Nd3+. Uma investigação estrutural detalhada de uma série destes vidros foi conduzida utilizando espectroscopias Raman, de ressonância magnética nuclear de estado sólido (RMN) e de ressonância paramagnética eletrônica (EPR).

Testo completoDuring syringe hot forming, tungsten-glass interactions lead to oxidation and wear of the tungsten tool and contamination of the syringe by tungsten. Direct consequences are unwanted reactions with sensitive medicines I contained in the syringes. Oxidation and wear of the tungsten tool was studied in air and in glass at high temperature, during dedicated experiments and during the syringe forming process. Thanks to the understanding of these phenomena, solutions to avoid contamination of the syringe by tungsten were proposed

Testo completoThe planar design of solid oxide fuel cell (SOFC) is the most promising one due to its easier fabrication, improved performance and relatively high power density. In planar SOFCs and other solid-electrolyte devices, gas-tight seals must be formed along the edges of each cell and between the stack and gas manifolds. Glass and glass-ceramic (GC), in particular alkaline-earth alumino silicate based glasses and GCs, are becoming the most promising materials for gas-tight sealing applications in SOFCs. Besides the development of new glass-based materials, new additional concepts are required to overcome the challenges being faced by the currently existing sealant technology. The present work deals with the development of glasses- and GCs-based materials to be used as a sealants for SOFCs and other electrochemical functional applications. In this pursuit, various glasses and GCs in the field of diopside crystalline materials have been synthesized and characterized by a wide array of techniques. All the glasses were prepared by melt-quenching technique while GCs were produced by sintering of glass powder compacts at the temperature ranges from 800−900 ºC for 1−1000 h. Furthermore, the influence of various ionic substitutions, especially SrO for CaO, and Ln2O3 (Ln=La, Nd, Gd, and Yb), for MgO + SiO2 in Al-containing diopside on the structure, sintering and crystallization behaviour of glasses and properties of resultant GCs has been investigated, in relevance with final application as sealants in SOFC. From the results obtained in the study of diopside-based glasses, a bilayered concept of GC sealant is proposed to overcome the challenges being faced by (SOFCs). The systems designated as Gd−0.3 (in mol%: 20.62MgO−18.05CaO−7.74SrO−46.40SiO2−1.29Al2O3 − 2.04 B2O3−3.87Gd2O3) and Sr−0.3 (in mol%: 24.54 MgO−14.73 CaO−7.36 SrO−0.55 BaO−47.73 SiO2−1.23 Al2O3−1.23 La2O3−1.79 B2O3−0.84 NiO) have been utilized to realize the bi-layer concept. Both GCs exhibit similar thermal properties, while differing in their amorphous fractions, revealed excellent thermal stability along a period of 1,000 h. They also bonded well to the metallic interconnect (Crofer22APU) and 8 mol% yttrium stabilized zirconium (8YSZ) ceramic electrolyte without forming undesirable interfacial layers at the joints of SOFC components and GC. Two separated layers composed of glasses (Gd−0.3 and Sr−0.3) were prepared and deposited onto interconnect materials using a tape casting approach. The bi-layered GC showed good wetting and bonding ability to Crofer22APU plate, suitable thermal expansion coefficient (9.7–11.1 × 10–6 K−1), mechanical reliability, high electrical resistivity, and strong adhesion to the SOFC componets. All these features confirm the good suitability of the investigated bi-layered sealant system for SOFC applications.
A concepção planar de células de combustível de óxido sólido (SOFC) é a mais promissora devido a sua fabricação mais fácil, um melhor desempenho e uma densidade de potência relativamente elevada. Nas SOFCs planares e outros dispositivos de electrólitos sólidos são necessárias vedações estanques ao gás ao longo das arestas de cada uma das células e entre os tubos de distribuição de gás e de pilha. Materiais vítreos e vitrocerâmicos (GC), em particular com composições baseadas em aluminosilicatos alcalino-terrosos, estão entre os materiais mais promissores para aplicações de vedação à prova de gás em SOFCs. Além do desenvolvimento de novos materiais à base de vidros e vitrocerâmicos, são também necessários novos conceitos para superar os desafios enfrentados pela tecnologia selante atualmente existente. O presente trabalho visa dar um contributo nesse sentido, propondo soluções de vedação para SOFCs e outras aplicações electroquímicas. Para o efeito, foram sintetizados vários vidros e GCs à base de diópsido, os quais foram caracterizados por recurso a uma grande variedade de técnicas. Todos os vidros foram preparados por fusão, enquanto os GCs foram produzidos por sinterização (tratamento térmico) de compactos de pó de vidro nas faixas de temperatura de 800 − 900 ºC por 1 − 1000 h. Além disso, foram estudados os efeitos de diversas substituições iónicas, especialmente de CaO por SrO, e de MgO + SiO2 por Ln2O3 (Ln = La, Nd, Gd, e Yb), em composições de aluminosilicatos à base de diópsido na estrutura, sinterização e cristalização dos vidros e nas propriedades dos GCs resultantes com particular relevância para as propriedades de vedação em SOFCs. Com base nos resultados obtidos neste estudo, foi possível propor um novo conceito de selante vritrocerâmico em bi-camadas que visa ultrapassar os desafios enfrentados pelos vedantes actualmente usados em SOFCs. Os sistemas designados por Gd−0,3 (em % molar: 20,62 MgO−18,05 CaO−7,74 SrO−46,40 SiO2−1,29 Al2O3−2,04 B2O3−3,87 Gd2O3) e Sr−0,3 (em % molar: 24,54 MgO−14,73 CaO−7,36 SrO−0,55 BaO−47,73 SiO2−1,23 Al2O3−1,23 La2O3−1,79 B2O3−0,84 NiO) foram seleccionados para realizar o conceito de bi-camada. Ambos os GCs exibem propriedades térmicas semelhantes, e excelente estabilidade térmica ao longo de um período de 1.000 horas, mas diferem nas suas fracções vítreas/cristalinas. Eles revelaram também elevada aptidão para se ligarem à interconexão metálica (Crofer22APU) e ao electrólito sólido (zircónia estabilizada com 8 mol% de ítria (8YSZ) sem a formação de camadas interfaciais indesejáveis entre os diferentes componentes das SOFCs. Duas camadas separadas compostas pelos vidros (Gd−0,3 e Sr−0.3) foram preparadas e depositadas sobre as interconexões metálicas através de uma abordagem tape casting. As bi-camadas vitrocerâmicas mostram boa capacidade de molhamento e ligação à placa Crofer22APU, coeficientes de expansão térmica adequados (9,7−11,1 × 10−6 K−1), confiabilidade mecânica, elevada resistividade eléctrica, e uma forte adesão aos componentes da SOFC. Todas estas características confirmam a boa adequação do sistema selante bi-camadas investigado para aplicações em SOFCs.

Testo completoThe use of glass has increased in the last decade. But glass is still not well known by designers because it has an unusual behavior when loaded, it is brittle. Glass acquires many of its characteristics during it manufacturing process, which is described. Then different structural improvements can be obtained, by treatments and assemblies and its latest developments. Mechanical behavior of glass is studied, and this completes the description of glass as a structural material. A second step is to study how glass is used in civil engineering, in a building's structural system. The tendency to "make the most of glass" has motivated designers to seek to improve the support system, often a weak aspect of glass in building. They are thus described as an important development that permits high performance glass structures. Finally, the latest improvements in the structural design and model of glass that have led to elaborated structures using glass are described.

In this thesis, I explore relationships between form generation, material properties, and design constraints in search of a new framework for designing with unpredictable or unstable material systems using glass 3D printing as a case study. Molten glass forming has always been difficult to accurately predict or model, but also offers a high degree of geometric complexity or hierarchy through organic formations. Top-down design approaches to material tunability and control are enabled by new digital fabrication tools and technologies that offer some of most successful attempts to design at scales approaching that of nature [38] [20]. Bottom-up, material-driven systems design functionality, itself, around organically formed structures to challenge our perspective of designing for utility, and how to define that utility [18]. The glass 3D printer, developed by The Mediated Matter Group in collaboration with the MIT Glass Lab, has been an important case study long in the making. A novel type of glass forming quickly gave way to a dialogue with highly unstable material behaviors, structures too complex to model in real time and visually compelling, frozen in time with cooling temperatures. The process generates new types of glass structures and visual output, enabling new design typologies for the product and architectural scale. Here I present an array of over a hundred unique design experiments that offer insight into this brand new design space created by complex glass behavior under control of a digital machine and harnessing structural instability. Close study not only of the objects generated but also their behavior during fabrication is key to understanding how the glass responds to the motion of the machine. Analysis of the project workflow itself provides the foundation for a framework capable of handling an active and complex material system, identifying how and when machine control can be used directly, how and when organic material formation can take place, and how the two interface from design tool to fabrication tool to design product. Finally, I look ahead to the potential for new product and architectural functionalities enabled by this platform, and I establish concepts for using the highly complex forms with the mapped "design space" as a guide for what we understand to be possible. The goal is to form new knowledge about material-informed digital fabrication through the generation of new glass forms and designs.
