Aerogeles de celulosa de la paja de arroz combinada con almidón

Alonso Collado, Paula (Universitat Politècnica de València, 2024-07-17)

[ES] La paja de arroz es un residuo agroalimentario que contiene compuestos de gran interés como la celulosa, y cuya revalorización es fundamental en el marco de la economía circular. En el presente trabajo se ha obtenido ...
Assessment of properties of recycled concrete by means of a highly fractioned factorial design of experiment

López-Gayarre, F.; Lopez-Colina, C.; Serrano-Lopez, M.A.; García Taengua, Emilio José; Lopez Martinez, A. (Elsevier, 2011-10)

The study presented in this paper has been carried out using a highly fractional factorial experimental design. This design allows the analysis of a greater number of factors and levels with a reduced number of mixes. In ...
Determining the influence of N-acetylation on water sorption in chitosan films

Gámiz González, Mª Amparo; Piskin, Ayse Esra; Pandis, C.; Chatzimanolis-Moustakas, C.; Kyritsis, A.; Marí Soucase, Bernabé; Gómez Ribelles, José Luís; Vidaurre Garayo, Ana Jesús (Elsevier, 2015-11-20)

Water absorption in chitosan rapidly increases when the deacetylation degree decreases between 85 and 45%. This seems to contradict the fact that water absorption in chitin is much lower than that of chitosan. The aim ...
Effects of simple and double grafting melon plants on mineral absorption, photosynthesis, biomass and yield

San Bautista Primo, Alberto; Calatayud Chover, Ángeles; González Nebauer, Sergio; Pascual España, Bernardo; Maroto Borrego, José Vicente; López Galarza, Salvador Vicente (Elsevier, 2011-09)

[EN] The Spanish type cultivar 'Piel de Sapo' (Cucumis melo L var. saccharinus), has a limited compatibility with the Cucurbita maxima x Cucurbita moschata hybrids currently used as rootstocks. Double grafting can be used ...
Estudio comparativo de las propiedades hídricas de los diferentes pétreos naturales

Ouahabi, Youssera (Universitat Politècnica de València, 2022-11-15)

[ES] En las sociedades actuales es indiscutible la atracción hacia todo lo presentado como nuevo. Evidentemente esta actitud se manifiesta también en el mercado de la construcción con la constante aparición de nuevos ...
Features of microwave fired utilitarian stoneware

Santos, Tiago; Santos, Nuno; Gomes, Celso; Hennetier, Luc; Costa, Vítor; Costa, Luís (Editorial Universitat Politècnica de València, 2019-10-15)

[EN] Both high temperature phases and microstructure transformations of stoneware products microwave and conventionally (gas and electric) fired are investigated aiming at a better understanding of factors affecting their ...
Flexural behavior and water absorption of asymmetrical sandwich composites from natural fibers and cork agglomerate core

Hoto, Rene; Furundarena Doval, Gurutze; Torres, J.P.; Muñoz Dominguez, Eva; Andrés de la Esperanza, Francisco Javier; García Manrique, Juan Antonio (Elsevier, 2014-07-15)

This work addresses an experimental investigation concerning flexural and water absorption behavior of a novel low-cost green composite asymmetric sandwich. For specimen manufacturing, an agglomerate cork panel and natural ...
Hybrid lime-pozzolan-geopolymer systems: microstructural, mechanical and durability studies

Villca, Ariel Rey; Soriano Martinez, Lourdes; Borrachero Rosado, María Victoria; Paya Bernabeu, Jorge Juan; Monzó Balbuena, José Mª; Mitsuuchi Tashima, Mauro (MDPI AG, 2022-04-08)

[EN] This work studies the possibility of using geopolymer materials to enhance the mechanical and durability properties of hydrated lime¿pozzolan mixtures, which gave rise to the so-called ¿hybrid systems¿. Two different ...
Hydrothermal ageing of polylactide/sisal biocomposites. Studies of water absorption behaviour and Physico-Chemical performance

Gil Castell, Óscar; Badía Valiente, José David; Kittikorn, T.; Stromberg, E.; Martinez-Felipe, Alfonso; Ek, M.; Karlsson, S.; Ribes Greus, María Desamparados (Elsevier, 2014-10)

An accelerated hydrothermal degrading test was designed in order to analyse the synergic effect of water and temperature on PLA/sisal biocomposites with and without coupling agent. As well, the physicochemical properties ...
