Chemical Changes in Pictorial Models: Characterization by FT-IR Spectroscopy
(2009)
Text en actes de congrés
Accés restringit per política de l'editorialIn order to understand the interaction between copper containing pigments and the organic binders in paintings, as well as reaction/alteration products, a series of pictorial models have been prepared and ... -
Detección de siliconas en tejidos defectuosos mediante espectrofotometría de FTIR
(Institut d'Investigació Tèxtil i Cooperació Industrial de Terrassa. Universitat Politècnica de Catalunya (UPC), 2010)
Article
Accés obertEl análisis de siliconas tiene una especial dificultad, debido a la elevada estabilidad de estos compuestos, a su viscosidad y a su baja solubilidad en disolventes convencionales. En este trabajo se emplea la espectrofotometría ... -
Determination of the recovered-fiber content in paperboard samples by applying mid-infrared spectroscopy
(2015-04-01)
Article
Accés obertPaperboard is widely used in different applications, such as packaging and graphic printing, among others. Consumption of recycled paper is growing, which has led the paper-mill packaging industry to apply strict quality ... -

(Universitat Politècnica de Catalunya, 2012-06)
Projecte Final de Màster Oficial
Accés restringit per decisió de l'autorEl present treball és un estudi sobre la possibilitat de l’anàlisi de vernissos antics aplicats en retaules i pintures mitjançant FTIR de transmissió i ATR. S’entén per vernissos antics tant aquells que van ser aplicats ... -
Micro infrared spectroscopy discrimination capability of compounds in complex matrices of thin layers in real sample coatings from artworks
(2015-01)
Article
Accés obertThe presence of coating on manufactures either to protect them from the environment, or to give them specific properties—as well as simply to change their aspect—has been shown to be a constant practise throughout history. ... -
Microanalytical study of luster glazed gilding and silvering from Baroque altarpieces
(2018-03-01)
Article
Accés obertLustering, a technique which involved the application of coloured translucent glazes over gilding and silvering was widely used to enrich and decorate altarpieces in the Baroque period. The decorations consist of a micrometric ... -

(2014-05-06)
Article
Accés obertThe blue pigments used on altarpieces in 15th Century in Catalonia and Crown of Aragon are principally the azurite mineral. To a lesser extent lapis lazuli, also of mineral origin and occasionally, in the background areas, ... -
Optimisation procedure for additive manufacturing processes based on mask image projection to improve Z accuracy and resolution
(Elsevier Ltd, 2018-01-04)
Article
Accés obertMask image projection is an additive manufacturing (AM) technique used in photocurable materials which allows the simultaneous energy delivery in a whole area instead of a single spot. A common problem for this AM process ...
