Reforma i canvi d’ús de l’Antic Ajuntament de Sant Feliu de Codines, situat al carrer Vic nº 1, a Escola Municipal de Música

El projecte consisteix en realitzar l’aixecament gràfic de l’antic Ajuntament de Sant Feliu de Codines , construït l’any 1.886, i realitzar un canvi d’ús projectant-ne una escola de música municipal. Aquest projecte consta d’una memòria descriptiva de l’estat actual, on es descriu una breu introducció de l’edifici i el seu entorn sense voler incidir gaire en aquests aspectes. La intenció principal és la de voler remarcar la situació en la que es troba l’edificació existent, deixant constància de la necessitat de rehabilitació, no només per la seva falta de prestacions vers la seguretat i la qualitat, sinó pel desaprofitament de totes les parts de l’edifici, sobretot tenint en compte que es pot aprofitar i promocionar un ús més adequat. Un cop definit l’objecte de rehabilitar i aportar un nou ús a l’edifici, primerament es fa una breu introducció de l’estructura actual de l’edifici i es proposa una hipòtesi de la nova estructura resultant, de la qual cal destacar que es procedirà a la realització d’un estintolament per tal de suprimir diverses parts de la paret de càrrega que tancaven l’espai de l’escala. Pel que fa a la memòria constructiva, es redacten totes les parts de l’edificació objecte d’aquest projecte: fusteria, paviments, acabats, materials, ... escollint aquelles opcions que siguin millor pel desenvolupament de l’activitat musical. Finalment es realitzarà un predisseny de la instal·lació de fontaneria, electricitat, sanejament i climatització. Per acabar trobarem la documentació gràfica i una sèrie d’annexos que complementen la informació abans descrita. Clarament l’objectiu principal del projecte és adaptar un edifici existent a les necessitats d’una escola de música municipal complint amb els requisits mínims marcats als documents bàsics del Codi Tècnic de l’Edificació. Per tant, el tema de l’acústica serà on més s’incidirà, ja que caldrà escollir les millors opcions per obtenir un bon aïllament acústic en tot l’edifici

Programmable self-assembling 3D architectures generated by patterning of swellable MOF-based composite films

The integration of swellable metal-organic frameworks (MOFs) into polymeric composite films is a straightforward strategy to develop soft materials that undergo reversible shape transformations derived from the intrinsic flexibility of MOF crystals. However, a crucial step toward their practical application relies on the ability to attain specific and programmable actuation, which enables the design of self-shaping objects on demand. Herein, a chemical etching method is demonstrated for the fabrication of patterned composite films showing tunable self-folding response, predictable and reversible 2D-to-3D shape transformations triggered by water adsorption/desorption. These films are fabricated by selective removal of swellable MOF crystals allowing control over their spatial distribution within the polymeric film. Upon exposure to moisture, various programmable 3D architectures, which include a mechanical gripper, a lift, and a unidirectional walking device, are generated. Remarkably, these 2D-to-3D shape transformations can be reversed by light-induced desorption. The reported strategy offers a platform for fabricating flexible MOF-based autonomous soft mechanical devices with functionalities for micromanipulation, automation, and robotics

Surface chemistry of metal-organic polyhedra

This work was funded by the CERCA Programme/Gen-eralitat de Catalunya and through a fellowship (LCF/BQ/PR20/ 11770011) from the "La Caixa" Foundation (ID 100010434).Metal-organic polyhedra (MOPs) are discrete, intrinsically-porous architectures that operate at the molecular regime and, owing to peripheral reactive sites, exhibit rich surface chemistry. Researchers have recently exploited this reactivity through post-synthetic modification (PSM) to generate specialised molecular platforms that may overcome certain limitations of extended porous materials. Indeed, the combination of modular solubility, orthogonal reactive sites, and accessible cavities yields a highly versatile molecular platform for solution to solid-state applications. In this feature article, we discuss representative examples of the PSM chemistry of MOPs, from proof-of-concept studies to practical applications, and highlight future directions for the MOP field

Metal-organic frameworks : from molecules/metal ions to crystals to superstructures

Altres ajuts: I.I. thanks MINECO for a Ramón y Cajal grant.Metal-organic frameworks (MOFs) are among the most attractive porous materials known today, exhibiting very high surface areas, tuneable pore sizes and shapes, adjustable surface functionality, and flexible structures. Advances in the formation of MOF crystals, and in their subsequent assembly into more complex and/or composite superstructures, should expand the scope of these materials in many applications (e.g., drug delivery, chemical sensors, selective reactors and removal devices, etc.) and facilitate their integration onto surfaces and into devices. This Concept article aims to showcase recently developed synthetic strategies to control the one-, two- and three-dimensional (1-, 2- and 3D) organisation of MOF crystals. Superstructures: Recent developments are described for the construction of the first-ever MOF superstructures, all of which entail control over MOF crystallisation and/or the subsequent spatial layout of the resulting crystals. These methods are characterised as 1) spontaneous higher-order assembly, 2) self-assembly using hard templates, 3) self-assembly using soft templates and 4) self-templated synthesis. © 2014 WILEY-VCH Verlag GmbH & Co.

Optimised room temperature, water-based synthesis of CPO-27-M metal-organic frameworks with high space-time yields

PMCID: PMC4902134The exceptional porosity of Metal-Organic Frameworks (MOFs) could be harnessed for countless practical applications. However, one of the challenges currently precluding the industrial exploitation of these materials is a lack of green methods for their synthesis. Since green synthetic methods obviate the use of organic solvents, they are expected to reduce the production costs, safety hazards and environmental impact typically associated with MOF fabrication. Herein we describe the stepwise optimisation of reaction parameters (pH, reagent concentrations and reaction time) for the room temperature, water-based synthesis of several members of the CPO-27/MOF-74-M series of MOFs, including ones made from Mg(ii), Ni(ii), Co(ii) and Zn(ii) ions. Using this method, we built MOFs with excellent BET surface areas and unprecedented Space-Time Yields (STYs). Employing this approach, we have synthesised CPO-27-M MOFs with record BET surface areas, including 1279 m2 g-1 (CPO-27-Zn), 1351 m2 g-1 (CPO-27-Ni), 1572 m2 g-1 (CPO-27-Co), and 1603 m2 g-1 (CPO-27-Mg). We anticipate that our method could be applied to produce CPO-27-Ni, -Mg, -Co and -Zn with STYs of 44 kg m-3 per day, 191 kg m-3 per day, 1462 kg m-3 per day and a record 18720 kg m-3 per day, respectively.This work was supported by the Spanish MINECO (project PN MAT2012-30994) and the EC (project FP7 ERC-Co 61594).

Colloidal metal-organic framework particles : the pioneering case of ZIF-8

The production of metal-organic frameworks (MOFs) in the form of colloids has brought a paradigm shift in the design of new functional porous materials. Along with their intrinsic interest as porous solids, and contrary to their bulk powder counterparts, colloidal MOF particles can additionally be dispersed, shaped, functionalized, transformed and assembled in a controlled manner, conferring them further properties and applications. In this regard, zeolitic imidazolate framework-8 (ZIF-8) has become a pioneering MOF constituent of colloidal science. Today, the understanding of the role of synthetic parameters, learned after one decade of research, enables the production of monodisperse colloidal ZIF-8 particles with tunable dimensions and morphologies, offering the opportunity to develop new functional materials and composites with novel and promising functionalities. This tutorial review provides a useful guide to prepare ZIF-8 in its colloidal form, covering the published studies on the synthesis of homogeneous ZIF-8 particles with controlled size and shape. In addition, we present the most relevant advances in the development of colloidal ZIF-8 hybrid single-particles, reflecting the great potential and rapid development of this interdisciplinary research field. Finally, we highlight how formulation of ZIF-8 as colloids has led to the emergence of novel physicochemical phenomena that are useful for practical applications. This review aims at promoting the development of MOFs as colloids, taking ZIF-8 as a pioneering and successful case that clearly shows the benefits of bridging MOF chemistry and colloidal science

Protection strategies for directionally-controlled synthesis of previously inaccessible metal-organic polyhedra (MOPs) : The cases of carboxylate: The amino-functionalised Rh(ii)-MOPs

Herein we report that strategic use of protecting groups in coordination reactions enables directional inhibition that leads to synthesis of highly functionalised metal-organic polyhedra (MOPs), rather than of the extended coordination networks. Using this approach, we functionalised two new porous cuboctahedral Rh(ii)-based MOPs with 24 peripheral carboxylic acid groups or 24 peripheral amino groups

Protecting metal-organic framework crystals from hydrolytic degradation by spray-dry encapsulating them into polystyrene microspheres

PMCID: PMC4876919Many metal-organic frameworks are water labile, including the iconic Hong-Kong University of Science and Technology-1 (HKUST-1). Spray-dry encapsulation of HKUST-1 crystals into polystyrene microspheres is reported here to yield composites that are resistant to water but retain most of the excellent gas sorption capacity of HKUST-1. These composites are demonstrated to exhibit superior water adsorption/desorption cycling, maintaining the level of water uptake even after three cycles.We thank the MINECO (Spain) for financial support through projects MAT2012-30994, CTQ2011-16009-E and EC FP7 ERC-Co 615954.

Copper(II)–Thymine Coordination Polymer Nanoribbons as Potential Oligonucleotide Nanocarriers

This is the peer reviewed version of the following article: Vegas, V. G., Lorca, R., Latorre, A., Hassanein, K., Gómez‐García, C. J., Castillo, O., ... & Amo‐Ochoa, P. (2017). Copper (II)–Thymine Coordination Polymer Nanoribbons as Potential Oligonucleotide Nanocarriers.

This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Use of Self-Archived VersionsThe direct reaction between copper nitrate, thymine-1-acetic acid, and 4,4′-bipyridine in water leads to the formation of a blue colloid comprising uniform crystalline nanoribbons (length >1 μm; width ca. 150–185 nm; diameter ca. 15–60 nm) of a coordination polymer. The polymer displays a thymine-based structure freely available for supramolecular interactions. These nanostructures show significant selective interaction with single-stranded oligonucleotides based on adenine. Remarkably, they present low cell toxicity in three cell lines–despite the copper(II) content–and can be used as nanocarriers of oligonucleotides. These results suggest the potential of these types of nanostructures in several biological applicationsFinancial support from the Spanish Ministerio de Economía y Competitividad (MAT2016‐75883‐C2‐2‐P, MAT2016‐77608‐C3‐1‐P, MAT2013‐46502‐C2‐1P/2P, MAT2013‐46753‐C2‐1‐P, MAT2010‐20843‐C02‐01, SAF2014‐56763‐R), Asociación Española Contra el Cáncer, Generalitat Valenciana (PrometeoII/2014/076 and ISIC) and EU (FP6‐029192).
