El sector de pasta i paper és considerat un dels set sectors industrials més intensius en consum energètic. La producció i consum d'electricitat i de vapor esdevenen les fonts majoritàries d'emissions de gasos d'efecte ...
Coming from renewable and sustainable raw materials, nanocelluloses are rapidly emerging as one of the most promising future materials. Recently, the use of nanocellulose nanocomposites in flexible electrodes, biosensors ...
In the recent years, significant interest on the production, characterization and application of cellulose nanofibers has brought out among scientific and technic authorities. This special attention mainly comes from their ...
Every year, the textile industry generates large amounts of cellulosic waste during the production and fabrication stages. This waste is made up of fibers, with lengths are less than 10 mm that prevent its reintroduction ...
Aquesta tesi doctoral i tot el treball experimental s’ha realitzat dintre les línies de treball del grup de recerca, Laboratori d’Enginyeria Paperera i Materials Polímers (LEPAMAP) de l’Escola Politècnica Superior de la ...
Nowadays the problem of climate change on planet Earth has aggravated, it has become extremely important to find solutions that considerably reduce or even eliminate its causes. Among the set of solutions that have been ...
The main goal of this thesis is the production and characterization of composites materials from a bio-based polyamide and natural fibres which could be more sustainable alternative to glass fibre reinforced polypropylene. ...
As a renewable alternative to petroleum-based materials, wood or plant-based materials offer a greater prospect in the transition towards sustainable replacements. Native to wood, cellulose nanofibers (CNF) form the major ...
Bio and nano technologies are absent or incipient in papermaking industry and, concretely, in recycling and high-yield pulps sectors. In this sense, the present Thesis uses cellulose nanofibers (CNF), both in bulk and on ...
To achieve a sand filter design that reduce its pressure loss, computational fluid dynamics (CFD) tecnique was used combined with laboratory tests in a scaled filter using different filter media. The CFD models allowed to ...
Nanocellulose is a sustainable nanomaterial with outstanding physico-mechanical properties, a fact that confers the nanomaterial a huge potential in sectors such as the papermaking, nanocomposites, aerogels for selective ...
Carbon dioxide (CO2) is largely emitted in the ignition of fossil fuels for transport, electricity generation or other industrial processes. CO2 is an inorganic compound that exists naturally on Earth, but its concentration ...
