In the last decade, conductive polymers have received great interest in both scientific and technological levels due to the electroactive properties exhibited by these materials. For this reason, the main aim of this ...
The human M3 muscarinic acetylcholine receptor (M3R) regulates many important physiological roles in the central and peripheral nervous systems, and it is involved in the pathophysiology of several neurodegenerative and ...
(English) Heterogeneous catalysis is one of the most important chemical technologies available today to produce most chemicals at the basis of industrial production. The transition to a greener energy production demands ...
Dinamisme, capacitat de resposta i flexibilitat són característiques essencials en el desenvolupament de la societat actual. Les noves tendències de globalització i els avenços en tecnologies de la informació i comunicació ...
CATALA <br/> <br/>La contaminació de les aigües superficials i subterrànies representa el problema mediambiental més greu a què s'ha d'enfrontar la indústria minera, a causa de les denominades aigües àcides de mina (AAM), ...
L'urani es troba present en el medi a baixes concentracions en roques, sòls i aigua, però l'activitat industrial i el desenvolupament de la tecnologia nuclear ha suposat la generació de grans quantitats de residus i zones ...
Due to the problems associated with the generation and storage of hydrogen in portable applications, the use of ammonia fer the on-site production of hydrogen through its catalytic decomposition has been proposed. This ...
El modelo actual del consumo energético basado en la utilización de combustibles fósiles requiere un replanteamiento debido al agotamiento de éstos y a las emisiones de gases contaminantes que generan. La obtención de ...
With the industrial and technological development of the present-day society, the presence of flammable and toxic substances has increased in a growing number of activities. Dispersion of hazardous gas releases occurring ...
Nowadays, rare earth elements (REEs) have gained importance due to their indispensable and critical use in many high-tech industries like hybrid cars, fluorescent lamps, flat screen televisions, mobile phones, disc drives ...
En general, el control de procesos es muy eficiente cuando el punto de operación deseado ha sido determinado a priori y el sistema tiene capacidad suficiente para responder a las perturbaciones. Mientras el control de ...
The residues resulting from orange and spinach processing, composed mainly by peels and seeds; and leaves, respectively, contain relevant amounts of polyphenols, so they can be used as raw material for recovery natural ...
The growing concern over environmental pollution in recent decades has placed increasing focus on research into the development of sustainable processes associated with the removal of contaminants in waters. Water is scarcer ...
The leather manufacturing process consists of a sequence of complex chemical reactions and mechanical processes that allow turning skin, a putrefiable by-product of alimentary industry, into leather, a stable high-value-added ...
The aluminum alloy AA2024-T3, u sed extensively in the aerospace industry, dueto the heterogeneous microstructures intentionally designed to optím ize the m echanical properties, is very susceptible to localízed corros ...
(English) The historical analysis performed has shown that jet fires have been the origin of a high number of domino effect accidents, both in the process industry and in the transportation of flammable fluids by pipelines ...
The most widely accepted option for the long-term management of radioactive waste materials considers their disposal in deep underground facilities (examples are Finland, Belgium, France, Sweden, etc.). Such installations ...
Chemical plants and other industrial installations process and store hazardous materials, which represent a certain risk to people, equipment and the environment. Overpressure is one of the most common upsets in process ...
Since the pioneering work of Reches and Gazit in 2003, in which the formation of diphenylalanine (FF) nanotubes in aqueous solution was discovered, significant efforts have been made to develop a new generation of biomaterials ...
A more sustainable and secure energy supply is required for the forthcoming generations; where the actual dependence on the fossil fuel reserves should be replaced by self-sufficiency and use of renewable energy resources. ...
