Free-Form, High Energy Performance, Transparent Envelope

This article examines, from the energy viewpoint, a new lightweight, slim, high energy efficient, light-transmitting envelope system, providing for seamless, free-form designs for use in architectural projects. The research was based on envelope components already existing on the market, especially components implemented with granular silica gel insulation, as this is the most effective translucent thermal insulation there is today. The tests run on these materials revealed that there is not one that has all the features required of the new envelope model, although some do have properties that could be exploited to generate this envelope, namely, the vacuum chamber of vacuum insulated panels (VIP), the monolithic aerogel used as insulation in some prototypes, reinforced polyester barriers. By combining these three design components — the high-performance thermal insulation of the vacuum chamber combined with monolithic silica gel insulation, the free-form design potential provided by materials like reinforced polyester and epoxy resins—, we have been able to define and test a new, variable geometry, energy-saving envelope system

A New Envelope with Highly Energy-Efficient Insulation

This article examines, from the insulation viewpoint, a new lightweight, slim, highly energy-efficient, light-transmitting envelope system, providing seamless, free form designs for use in architectural projects. The research was based on envelope components that are already on the market, especially components implemented with granular silica gel insulation, because this is the most effective translucent thermal insulation available today. The tests run on these materials revealed that there is no single component that has all the features required of the new envelope model. However, some do have properties that could be exploited to generate this envelope, namely the vacuum chamber of VIP panels, monolithic aero gel used as insulation in some prototypes and reinforced polyester barriers. By combining these three design components, the high-performance thermal insulation of the vacuum chamber, combined with monolithic silica gel insulation and the free-form design potential provided by materials like reinforced polyester and epoxy resins, we have been able to define and test a new, variable geometry, envelope insulation system with excellent energy-saving level

Síntesis de monómeros m-terfenildicarboxílicos para la preparación de membranas de naturaleza poliamídica

Mediante la reacción de Suzuki-Miyaura se han obtenido una serie de ácidos m-terfenilo3,3”-dicarboxílico con diferentes sustituyentes en la posición 5’. El acoplamiento se ha realizado a partir del ácido 3-carboxi-fenilborónico y los correspondientes derivados de 1,3dibromobenceno sustituidos en C-5, utilizando catalizadores de (PPh3)4Pd0. Se pretende preparar estos compuestos con un rendimiento y coste razonables, así como proporcionar una descripción experimental detallada y reproducible. En última instancia, en investigaciones posteriores a este TFG, los derivados terfenílicos se emplearan como comonómeros, junto a diaminas, en la formación de las membranas poliamídicas.Grado en Químic

Aprovechamiento del caucho proveniente de neumáticos fuera de uso en elastómeros autorreparables

El objetivo general de este trabajo de investigación ha sido evaluar el potencial de aprovechamiento del caucho procedente de neumáticos fuera de uso (NFU), para mejorar el rendimiento de cauchos autorreparables. Para ello, se han correlacionado la macro y microestructura del polvo de caucho de NFU (GTR) y del producto desvulcanizado derivado (dGTR), con las propiedades y el comportamiento de un caucho estireno-butadieno (SBR) autorreparable.Departamento de Física de la Materia Condensada, Cristalografía y MineralogíaDoctorado en Ingeniería Industria

F²TE³: A Transparent semi-monocoque VIP Envelope

This article examines a new lightweight, slim, high energy efficient, light-transmitting, self-supporting envelope system, providing for seamless, free-form designs for use in architectural projects. The system exploits vacuum insulation panel technology. The research was based on envelope components already existing on the market and patents and prototypes built by independent laboratories, especially components implemented with silica gel insulation, as this is the most effective transparent thermal insulation there is today. The tests run on these materials revealed that there is not one that has all the features required of the new envelope model, although some do have properties that could be exploited to generate this envelope, namely, the vacuum chamber of vacuum insulation panels, the use of monolithic aerogel as insulation in some prototypes, and reinforced polyester barriers. These three design components have been combined and tested to design a new, variable geometry, energy-saving envelope system that also solves many of the problems that other studies ascribe to the use of vacuum insulation panels

Simulation study on the fleet performance of shared autonomous bicycles

Rethinking cities is now more imperative than ever, as society faces global challenges such as population growth and climate change. The design of cities can not be abstracted from the design of its mobility system, and, therefore, efficient solutions must be found to transport people and goods throughout the city in an ecological way. An autonomous bicycle-sharing system would combine the most relevant benefits of vehicle sharing, electrification, autonomy, and micro-mobility, increasing the efficiency and convenience of bicycle-sharing systems and incentivizing more people to bike and enjoy their cities in an environmentally friendly way. Due to the uniqueness and radical novelty of introducing autonomous driving technology into bicycle-sharing systems and the inherent complexity of these systems, there is a need to quantify the potential impact of autonomy on fleet performance and user experience. This paper presents an ad-hoc agent-based simulator that provides an in-depth understanding of the fleet behavior of autonomous bicycle-sharing systems in realistic scenarios, including a rebalancing system based on demand prediction. In addition, this work describes the impact of different parameters on system efficiency and service quality and quantifies the extent to which an autonomous system would outperform current bicycle-sharing schemes. The obtained results show that with a fleet size three and a half times smaller than a station-based system and eight times smaller than a dockless system, an autonomous system can provide overall improved performance and user experience even with no rebalancing. These findings indicate that the remarkable efficiency of an autonomous bicycle-sharing system could compensate for the additional cost of autonomous bicycles
