Nowadays, every company seeks to optimize its Supply Chain (SC) in response to competitive pressures or to acquire advantage of new flexibility in the restrictions on world trade. The process systems engineering research ...
The photocatalytic production of hydrogen from water and biomass derivatives such as ethanol, glycerol and sugars is a highly attractive strategy to generate environmentally benign hydrogen. Ethanol is more easily oxidized ...
This work facuses on the study of these processes on Ti02 and Ce02, respectively. Although the development of photocatalytic research with the use of semiconductor photocatalysts does not last longer than about 40 years, ...
Las tendencias del mercado han hecho que las empresas cambien su forma de hacer negocios. La Globalización ha permitido a las empresas tener la posibilidad de acceder a distintos proveedores y mercados globalmente dispersos. ...
Current Supply chain (Se) decision support tools are devoted to the optimization of one objective function from a bias centralized perspective, without considering the coexistence with other participants and their uncertain ...
The rare earth elements (REEs) are essential ingredients for the development of modern industry and the transition to a more sustainable economy model. The unique physicochemical features of these elements, such as their ...
Most of the urban wastewater treatment plants (WWTP), based on conventional activated sludge (CAS) systems, cannot be considered sustainable since the concept of resources (energy and nutrients) recovery is not taken into ...
Los tejidos de algodón se someten a procesos de preparación (desencolado, descrudado y blanqueo) basados en la eliminación de impurezas presentes en la superficie de la fibra. Actualmente se blanquean con peróxido de ...
Current market trend is moving to miniaturized specimens, especially in the biomedical field seeking high effective and less invasive treatrnent. Ultrasound (US) micromolding is a new technique developed to the aim of ...
Els ports de mar constitueixen una infraestructura molt important en els països costaners, tant des del punt de vista econòmic com social. Però a la vegada són sistemes molt complexes des del punt de vista ambiental, ja ...
La presente tesis va encaminada al estudio de la gravedad de los accidentes industriales con sustancias peligrosas mediante la utilización del análisis histórico de accidentes. Su objetivo final es utilizar el tratamiento ...
En el campo de la cinética de la pirólisis de biomasa se han desarrollado numerosos trabajos de investigación que no acaban de resolver aspectos básicos del proceso. El análisis de resultados termogravimétricos aún requiere ...
Cementitious materials are used to condition or stabilise waste and to build infrastructure in disposal sites. Moreover, they are envisaged to form part of engineered barrier systems as container, backfill or liner materials ...
This thesis consists of a compendium of five works that illustrate the utilization of selected mathematical methods to solve specific chemical engineering problems. Hence, the thesis is intended to cover both, a review of ...
Los materiales compuestos nanoestructurados son considerados una opción prometedora para la concepción de materiales multifuncionales. Sin embargo, la falta habitual de interacción entre los componentes orgánicos e ...
Accidental releases of flammable hydrocarbons in chemical process industries can trigger severe hazards: explosions, fires, and dispersion of toxic vapour clouds. Explosions and toxic releases may injure people within large ...
Materials derired from chicken feathers could be used advantageously in composite building material apptications. Such applications could potentially consume the five billion pounds of feathers produced annually as a ...
Phosphorus in wastewater is mainly present as inorganic phosphate forms and is commonly removed through chemical co-precipitation using Al(III) and Fe(III) salts. However, precipitation is expensive and generates a waste ...
Many historical objects have coatings or varnish layers on the surface. In order to determine their conservation and historical contextualization is necessary to know its origin, why they were applied, the application ...
