Sergio Aguillón-Mata
No full textComo parte de nuestro curso de la gramática avanzada, leímos la obra “Dafeng” escrito por un ensayista de México que se llama Sergio Aguillón-Mata. La meta era poder familiarizarnos con un género literario en español—y en particular con los ensayos—prestando la atención a la gramática que se utiliza. Por medio de la lectura, pudimos aprender un nuevo estilo lingüística y la gramática asociada con este género. El propósito de nuestra investigación del ensayo era hacer conexiones importantes y un análisis de la gramática contenida en el texto. A parte de esto, tuvimos la oportunidad de interactuar con el ensayista Sergio Aguillón-Mata acerca de su obra “Dafeng” en una entrevista virtual. Aquí presentamos nuestros descubrimientos y nuestro análisis de la gramática en los ensayos

Creación de una marca de moda y diseño y producción de una colecciónSergio Casanova y Carmen
No full textEl presente Trabajo Final de Grado consta de dos partes:
Por un lado, se ha creado la marca de moda Sergio Casanova y se ha definido
su imagen corporativa y su identidad visual. Para la construcción de esta
firma han sido realizados análisis de competencia y del público objetivo, se
han establecido los valores, la filosofía de la misma y se ha desarrollado una
propuesta de merchandising. Sergio Casanova ambiciona ocupar un lugar entre
los diseñadores emergentes, por su espíritu transgresor, su unicidad, su
elegancia y su aspiración a una moda más ética y razonable.
Por otro lado, se ha diseñado parte de la primera colección de la marca, a
la que se le ha dado un nombre evocador de sueños, de música, de color, de
carácter, que posee una personalidad propia: Carmen. Esta colección tiene
dos objetivos claros: reflejar la esencia del Mediterráneo con lenguajes nuevos
y modernos e impulsar una industria textil valenciana que se encuentra
en decadencia. Estos propósitos se pretenden cumplir combinando tejidos
como la manta morellana, el terciopelo martelé, el raso y el viniloThe present Final Degree Project consists of two parts:
On one hand, the fashion brand Sergio Casanova has been created and
its corporate image and visual identity have been defined. For the construction
of this firm, competitive and target audience analyzes have been carried
out, the values have been established, the philosophy and a merchandising
proposal has been developed. Sergio Casanova wants to take a place among
emerging designers, for his transgressive spirit, his uniqueness, his elegance
and his aspiration to a more ethical and reasonable fashion.
On the other hand, part of the first collection of the brand has been designed,
which has been given an evocative name of dreams, music, color, character,
which has its own personality: Carmen. This collection has two clear
objectives: to reflect the essence of the Mediterranean with new and modern
languages and to promote a Valencian textile industry that is in decline.
These purposes are intended to be achieved by combining fabrics such as the
manta blanket, the hammered velvet, the satin and the vinyl.Martínez Sahagún, S. (2018). Creación de una marca de moda y diseño y producción de una colecciónSergio Casanova y Carmen. https://riunet.upv.es/handle/10251/108393TFG

Ligand-Free Suzuki–Miyaura Cross-Coupling Reactions in Deep Eutectic Solvents: A Novel Sustainable Approach Towards Bi- And Tri(Hetero)Aryl Compounds
No full textThe environmental impact associated with chemical synthesis has recently posed severe and compelling
demands for sustainable chemistry. The development of cost-effective and environmentally benign
reaction systems in place of volatile and harsh organic molecules represents an active field of research.
In the last decade, Deep Eutectic Solvents (DESs) have emerged as new and promising alternative green
reaction media. They are generally composed of two or three safe and inexpensive components, which
are able to engage in hydrogen-bond interactions with each other to form an eutectic mixture with a
melting point much lower than that of either of the individual components1.
Building on our recently investigations on the use of organometallics in unconventional reaction media
(e.g., DESs, water)2, in this Communication the effectiveness of bio-based DESs in forging new bi- and
tri(hetero)aryl adducts (yields up to > 98%) by exploiting a ligand-free Suzuki-Miyaura cross-coupling
reaction with either arylboronic acids or aryl potassium trifluoroborates, under mild reaction conditions
(T = 60 °C) and under air, will be discussed.

Hybrid membranes for wastewater treatment based on polymer-coated barium titanate nanoparticles
No full textIn this work we present a series of hybrid membranes with piezocatalytic properties for wastewater treatment. For this, four types of barium titanate nanoparticles (BTO NPs) with different coatings were synthesized. These NPs were embedded in a polystyrene (PS) matrix to fabricate hybrid, porous membranes using the breath figures (BF) technique. In-depth electron microscopy analysis showed that the NPs with an amphiphilic coating composed of PS (hydrophobic, compatibilizing them with the PS matrix) and hydrocaffeic acid (HCA) (hydrophilic, favoring the formation of ordered pores) led to the formation of honeycomb-patterned films where these NPs are selectively placed inside of the pores for a wide range of concentrations, from 5 to 100 wt%. We demonstrated the potential of these membranes in piezocatalysis applications, through proof-of-concept studies of methylene blue (MB) degradation in aqueous solutions
