    EL ALARMANTE INCREMENTO DE LA CONTAMINACION MEDIOAMBIENTAL HA ACELERADO EL DETERIORO DE LOS EDIFICIOS HISTORICOS Y CONTEMPORANEOS DE NUESTRAS CIUDADES, CONVIRTIENDOSE SU CONSERVACION EN UN IMPORTANTE DESAFIO PARA LA SOCIEDAD ACTUAL. OTRO RETO FUNDAMENTAL ES LA OPTIMIZACION DE LOS PROCESOS INDUSTRIALES, REDUCIENDO EL VOLUMEN DE EMISIONES A LA ATMOSFERA Y PROMOVIENDO LA UTILIZACION DE RECURSOS Y MATERIAS PRIMAS SOSTENIBLES. A AMBOS DESAFIOS SE DA RESPUESTA EN ESTE PROYECTO CUYO OBJETIVO GENERAL ES DESARROLLAR MATERIALES DE CONSTRUCCION EN LOS QUE SE MINIMICEN LOS EFECTOS DE LA CONTAMINACION AMBIENTAL A TRES NIVELES: (1) DESARROLLO DE MATERIALES DE CONSTRUCCION QUE INCREMENTEN SU DURABILIDAD FRENTE A LA ACCION DE LOS AGENTES CONTAMINANTES; (2) DESARROLLO DE MATERIALES DE CONSTRUCCION QUE ATRAPEN CONTAMINANTES; (3) DISEÑO DE SINTESIS ECOSOSTENIBLES, MEDIANTE EL USO DE REACTIVOS RECICLADOS Y/O DE ORIGEN NATURAL. ADEMAS, SE EVITARA LA ADICCION DE DISOLVENTES ORGANICOS VOLATILES._x000D_ EL EQUIPO DE INVESTIGACION SOLICITANTE DE ESTA PROPUESTA ES PIONERO EN LA SINTESIS DE PRODUCTOS CON APLICACION EN LA PROTECCION Y CONSERVACION DE MATERIALES DE CONSTRUCCION. EN CONCRETO, ESTOS PRODUCTOS INNOVADORES Y DE BAJO COSTE SON OBTENIDOS MEDIANTE UNA RUTA SOL-GEL, EMPLEANDO UN TENSIOACTIVO PARA FORMAR UN GEL NANOESTRUCTURADO Y LIBRE FRACTURAS. ESTOS MATERIALES REPRESENTAN EL PUNTO DE PARTIDA DE LA INVESTIGACION DEL PRESENTE PROYECTO, EN EL QUE, PARA CUMPLIR EL OBJETIVO GENERAL PROPUESTO, SE FIJAN LOS TRES OBJETIVOS ESPECIFICOS QUE SE DESCRIBEN EN LOS SIGUIENTES PARRAFOS: _x000D_ 1. DESARROLLO DE MATERIALES SUPERHIDROFUGANTES Y AUTOLIMPIANTES POR SU ACCION REPELENTE AL AGUA. SE PRETENDE MODIFICAR LA RUGOSIDAD SUPERFICIAL DE LOS MATERIALES DE CONSTRUCCION, MEDIANTE MECANIZACION CON LASER, COMO PASO PREVIO A LA APLICACION DE PRODUCTOS HIDROFUGANTES, DESARROLLADOS POR NUESTRO GRUPO INVESTIGADOR, CAPACES DE REDUCIR LA ENERGIA SUPERFICIAL. ESTOS MATERIALES CONSTRUCCION OPTIMIZADOS DARAN ORIGEN A SUPERFICIES SUPERHIDROFUGANTES (HIDROFOBICAS Y REPELENTES) EN LOS QUE NO SERA POSIBLE LA ENTRADA DE AGENTES CONTAMINANTES DISUELTOS. ADEMAS, EL EFECTO REPELENTE DOTARA A ESTAS SUPERFICIES DE PROPIEDADES AUTOLIMPIANTES._x000D_ 2. DESARROLLO DE MATERIALES AUTOLIMPIANTES, DESCONTAMINANTES Y BIOCIDAS POR SU ACCION FOTOCATALITICA. SE PRETENDE SINTETIZAR NANOPARTICULAS METALICAS CON PROPIEDADES PLASMONICAS A PARTIR DE RUTAS SIMPLES ECOLOGICAS Y DE BAJO COSTE. UNA APROXIMACION INTERESANTE SERA EL EMPLEO, COMO AGENTE REDUCTOR, DE EXTRACTOS ACUOSOS PROCEDENTES DE PRODUCTOS NATURALES, COMO LA HOJA DE GERANIO. ESTAS PARTICULAS SERAN INTEGRADAS EN FORMULACIONES FOTOACTIVAS SILICE-TITANIO DESARROLLADAS POR NUESTRO GRUPO INVESTIGADOR. EL FIN ULTIMO DE ESTE OBJETIVO ES CONSEGUIR UN EFECTO SINERGICO DEL TITANIO CON LAS PARTICULAS METALICAS, QUE DE ORIGEN A UN MATERIAL DE CONSTRUCCION CON SIGNIFICATIVA ACTIVIDAD FOTOCATALITICA, CAPAZ DE PROPORCIONARLE PROPIEDADES DESCONTAMINANTES Y AUTOLIMPIANTES, Y ADEMAS, ACTIVIDAD BIOCIDA._x000D_ 3. DESARROLLO DE MATERIALES DESCONTAMINANTES POR SU ACTIVIDAD SECUESTRANTE DE CO2. CON ESTE OBJETIVO, SE DESARROLLARAN DOS ESTRATEGIAS DIFERENTES. LA PRIMERA APROXIMACION CONSISTIRA EN LA REUTILIZACION DE RESIDUOS INDUSTRIALES RICOS EN FOSFOYESOS PARA EL SECUESTRO MINERAL DE CO2. LA SEGUNDA APROXIMACION CONSISTE EN LA UTILIZACION DE MONTMORILLONITAS Y OTRAS ARCILLAS DE ORIGEN NATURAL, PROCESADAS COMO MONOLITOS CON FORMA DE PANAL DE ABEJA, PARA ADSORBER ESTE CONTAMINANTE.

    THE ALARMING INCREASE IN ENVIRONMENTAL POLLUTION HAS ACCELERATED THE DETERIORATION OF HISTORIC AND CONTEMPORARY BUILDINGS IN OUR CITIES, MAKING THEIR CONSERVATION A MAJOR CHALLENGE FOR TODAY’S SOCIETY. ANOTHER KEY CHALLENGE IS THE OPTIMISATION OF INDUSTRIAL PROCESSES, REDUCING THE VOLUME OF EMISSIONS TO THE ATMOSPHERE AND PROMOTING THE USE OF SUSTAINABLE RESOURCES AND RAW MATERIALS. BOTH CHALLENGES ARE ANSWERED IN THIS PROJECT WHOSE GENERAL OBJECTIVE IS TO DEVELOP CONSTRUCTION MATERIALS THAT MINIMISE THE EFFECTS OF ENVIRONMENTAL POLLUTION AT THREE LEVELS: (1) DEVELOPMENT OF BUILDING MATERIALS THAT INCREASE THEIR DURABILITY AGAINST THE ACTION OF POLLUTANTS; (2) DEVELOPMENT OF CONSTRUCTION MATERIALS THAT TRAP CONTAMINANTS; (3) ECO-SUSTAINABLE SYNTHESIS DESIGN, BY USING RECYCLED REAGENTS AND/OR OF NATURAL ORIGIN. In addition, the adaptation of VOLATILE ORGANIC DISOLVENTS will be avoided._x000D_ THE REQUESTING RESEARCH EQUIPMENT OF THIS PROPOSAL IS PIONERY IN THE SINTESIS OF PRODUCTS WITH APPLICATION IN THE PROTECTION AND CONSERVATION OF CONSTRUCTION MATERIALS. IN PARTICULAR, THESE INNOVATIVE AND LOW-COST PRODUCTS ARE OBTAINED THROUGH A SUN-GEL ROUTE, USING A SURFACTANT TO FORM A NANOSTRUCTURED GEL AND FREE FRACTURES. THESE MATERIALS REPRESENT THE STARTING POINT OF THE RESEARCH OF THIS PROJECT, WHERE, IN ORDER TO ACHIEVE THE PROPOSED GENERAL OBJECTIVE, THE THREE SPECIFIC OBJECTIVES DESCRIBED IN THE FOLLOWING PARAGRAPHS ARE SET OUT: _x000D_ 1. DEVELOPMENT OF SUPERHIDROFUGANT MATERIALS AND SELF-CLEANING FOR THEIR WATER REPELLENT ACTION. IT IS INTENDED TO MODIFY THE SURFACE ROUGHNESS OF CONSTRUCTION MATERIALS, BY MECHANISATION WITH LASER, AS A STEP PRIOR TO THE APPLICATION OF HYDROFUGANT PRODUCTS, DEVELOPED BY OUR RESEARCH GROUP, ABLE TO REDUCE SUPERFICIAL ENERGY. THESE OPTIMISED CONSTRUCTION MATERIALS WILL GIVE RISE TO SUPERHIDROFUGANT SURFACES (HYDROPHOBICS AND REPELLENTS) IN WHICH THE ENTRY OF DISSOLVED CONTAMINANTS WILL NOT BE POSSIBLE. In addition, THE REPELLENT EFFECT will equip these SUPERFICIES OF AUTOMIMPIANT PROPERTYS._x000D_ 2. DEVELOPMENT OF SELF-CLEANING, DECONTAMINANT AND BIOCIDAL MATERIALS DUE TO ITS PHOTOCATALITICA ACTION. THE AIM IS TO SYNTHESISE METAL NANOPARTICULATES WITH PLASMONICAS PROPERTIES FROM SIMPLE ECOLOGICAL AND LOW-COST ROUTES. AN INTERESTING APPROACH WILL BE THE USE, AS A REDUCING AGENT, OF AQUEOUS EXTRACTS FROM NATURAL PRODUCTS, SUCH AS GERANIUM LEAF. THESE PARTICLES WILL BE INTEGRATED INTO PHOTOACTIVE FORMULATIONS SILICE-TITANIUM DEVELOPED BY OUR RESEARCH GROUP. The ULTIME FIN OF THIS OBJECTIVE IS TO A Synergical EFFECT OF THE TITANY WITH THE METALICAL PARTICULES, THAT OF ORIGINING TO A CONSTRUCTION MATERIAL WITH SIGNIFICATIVE ACTIVITY Photocatalitica, CHANGE TO provide you with decontaminating AND AUTOLIMPIANT PROPERTYS, AND ADEMAS, BIOCID ACTIVITY._x000D_ 3. DEVELOPMENT OF DECONTAMINATING MATERIALS DUE TO THEIR CO2 SEQUESTRATION ACTIVITY. TO THIS END, TWO DIFFERENT STRATEGIES WILL BE DEVELOPED. THE FIRST APPROACH WILL CONSIST OF THE REUSE OF INDUSTRIAL WASTE RICH IN PHOSPHORUS FOR THE MINERAL SEQUESTRATION OF CO2. THE SECOND APPROACH CONSISTS OF THE USE OF MONTMORILLONITES AND OTHER CLAYS OF NATURAL ORIGIN, PROCESSED AS MONOLYTES SHAPED AS HONEYCOMB, TO ADSORB THIS CONTAMINANT. (English)
