Determinación de parámetros de diseño del vidrio laminado, para garantizar su comportamiento estructural, Trujillo 2018
'Dipartimento di Economia Universita di Perugia (IT)', 2018Co-Authors: Obando Garcia, Maria Del Carmen, Quiliche Paredes DanielAbstract:Laminated Glass is a very attractive material for architectural solutions for its transparency, relatively light weight, thermal and acoustic insulation, etc. Nevertheless, it is not used as a structural element, although it is a material with a tremendously effective behavior to resist compression stress, but inefficient to tensile stress. This work has focused on determining the parameters of laminated Glass design (Glass - polyvinyl butyral Sheet – Glass) in order that it can be used as a structural element. the calculation of these sandwich shape elements is a problem addressed in the mechanics of deformable bodies, so the creation of a new mathematical model is not necessary. The results obtained by laboratory experiments (bending tests), helped us determine that the strength of this tensile material is close to 20Mpa, that the limit compression stress of the Glass is approximately 100Mpa, we also obtained a modulus of elasticity of 75000Mpa. What they show that this serves as structural material under certain restrictions.TesisEl vidrio laminado es un material muy atractivo para soluciones de arquitectura por su transparencia, peso relativamente ligero, aislamiento térmico y acústico, etc.; sin embargo, no es usado como elemento estructural, pese a que es un material con un comportamiento tremendamente eficaz para resistir esfuerzos de compresión, pero ineficaz a tracción. Este trabajo se ha centrado en determinar los parámetros de diseño del vidrio laminado (vidrio- lamina de polivinil butiral- vidrio) para que pueda ser usado como elemento estructural, el cálculo de estos elementos tipo sándwich es un problema abordado en la mecánica de cuerpos deformables, por lo que la creación de un nuevo modelo matemático no es necesario. Los resultados obtenidos mediante experimentos de laboratorio (pruebas a flexión), nos ayudó a determinar que la resistencia de este material a la tracción es cercana a 20Mpa, que el esfuerzo a compresión límite del vidrio es aproximadamente 100Mpa, además obtuvimos un módulo de elasticidad de 75000 Mpa.

study of sol gel derived high tin content indium tin oxide ito films on silica coated soda lime silica Glass
Materials Letters, 2004Co-Authors: Prasanta Kumar Biswas, K Ortner, S KorderAbstract:Sol–gel indium tin oxide films (ITO) of different thickness (120±25−40 to 560±25−40 nm) and of various compositions (In:Sn=90:10, 70:30 and 50:50) prepared from In metal and Sn salt were deposited on silica-coated (∼200 nm thickness) Sheet Glass substrate by the spinning technique. The films were cured in reducing atmosphere (N2+H2O vapour) at 500±5 °C, and these were of bixbyite-type structure with cubic In2O3 phase. Directional hemispherical reflectance (Rh) and transmittance (Th) of the films were measured in the wavelength range 0.25–18 μm. The Rh in the IR region was found to be maximum (∼0.62 at 10 μm) for In:Sn=70:30 resulting in minimum thermal emissivity (ed=0.36). The thermal emissivity (ed) was evaluated from the relation, ed=1−Rh−Th (Th≈0 for Sheet Glass in the wavelength range 5–18 μm), and it was in the range 0.36–0.85. The achieved Sheet resistance of the films was in the range 55–1700 Ω/□. Resistivity of the films of relatively low Sheet resistance measured by van der Pauw method at ambient temperature was in the range (1.4±0.2)×10−3 to (3.5±0.6)×10−3 Ω cm, and it was minimum for In:Sn=70:30 which resulted in maximum carrier concentration. Free electron carrier concentration (N) and Hall mobility (μ) of the films were in the range (1.4±0.4)×1020 to (4.8±1.3)×1020 cm−3 and (9.5±2.4) to (13±3) cm2/V s, respectively. The Hall mobility of the films passes through minima with an increase in tin content.

effects of tin on ir reflectivity thermal emissivity hall mobility and plasma wavelength of sol gel indium tin oxide films on Glass
Materials Letters, 2003Co-Authors: Prasanta Kumar Biswas, K Ortner, Nimai Chand Pramanik, P K Chakraborty, V Hock, S KorderAbstract:Sol–gel indium tin oxide films (ITO) of various composition (In:Sn atomic ratio=90:10 to 30:70) prepared from salt-based precursors were deposited on bare and SiO2 coated (∼200 nm thickness) Sheet Glass substrates. The films were cured in air and then annealed under N2/H2O at ∼500 °C to obtain ITO films of thickness 250–320 nm. Directional hemispherical reflectance (Rh) and trasmittance (Th) of the films were measured in the wavelength range 0.25–18 μm. The reflectance of the films at 10 μm (near the peak wavelength of black body radiation) was in the range 0.18–0.55. The thermal emissivity (ed) was evaluated from the relation: ed=1−Rh−Th (Th≈0, for Sheet Glass in the wavelength range 5–18 μm) and it was in the range 0.47–0.90. Reflectance (Rh) was also evaluated from measured Sheet resistance values (R□), from the relation Rh=(1+2e0c0R□)−2, where e0 and c0 are the permittivity of electron in vacuum and velocity of light, respectively. Specific resistivity of the films, measured by van-der Pauw method at ambient temperature was in the range 1.7±0.3×10−3 to 6.6±1.2×10−3 Ω cm. The Sheet resistance (R□) of the films was in the range 68–212 Ω/□. Free electron carrier concentration (N) and Hall mobility (μ) of the films were in the ranges (0.66±0.18)×1020 to (3.7±1.0)×1020 cm−3 and (4.4±1.5) to (20±5) cm2/V s, respectively. These values were utilized to evaluate plasma wavelength (λP) of the conducting films which were in the range 1.72±0.24–4.07±0.58 μm. Considerable variations of the above properties were observed with increasing Sn content but minimum thermal emissivity and maximum IR reflectivity were observed in the case of In:Sn=70:30.

giuseppe zecchin imprenditore vetrario importante ma poco conosciuto a murano e venezia nell ottocento
Rivista della Stazione sperimentale del vetro, 2009Co-Authors: Paolo ZecchinAbstract:Giuseppe Zecchin was one of the most important Venetian Glass Glassmaker of the nineteenth 9 century. At the turn of the century, his father Lorenzo, acted as the director of a Sheet Glass factory in Murano, owned by Stefano Motta; Lorenzo later became a partner in the firm. Only a few years prior, said partnership would have been deemed impossible. Lorenzo Zecchin was from Friuli and -according to the laws of the Serenissima Republic -only citizens born in Murano had the right to become Glass masters or to own Glass factories. By 1822, Lorenzo managed his own factory and when he died in 1827, his son, Giuseppe, inherited it. The factory started producing mirrors, working with smoothing techniques and the application of reflective paper on 'quari'. However, business suffered due to competition from other European countries where various phases of t heprocess were done mechanically.
