    • Ageing of resin from Pinus species assessed by infrared spectroscopy 

      Beltran Sanchidrian, Victòria; Salvadó Cabré, Nativitat; Buti Papiol, Salvador; Pradell Cara, Trinitat (2016-04-06)
      Article
      Open Access
      Resins obtained from Pinus genus species have been widely used in very different fields throughout history. As soon as the resins are secreted, molecular changes start altering their chemical, mechanical and optical ...
    • Identificació de vernissos històrics mitjançant FTIR 

      Beltran Sanchidrian, Victòria (Universitat Politècnica de Catalunya, 2012-06)
      Master thesis
      Restricted access - author's decision
      El 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 ...
    • Low molecular weight organic acid salts, markers of old fungi activity in wall paintings 

      Salvadó Cabré, Nativitat; Buti Papiol, Salvador; Pradell Cara, Trinitat; Beltran Sanchidrian, Victòria; Cinque, Gianfelice; Juanhuix, Jordi; Font, Lídia; Senserrich, Rosa (2016-02-21)
      Article
      Open Access
      Micro-Infrared Spectroscopy (mSR-FTIR) and X-ray diffraction (mSR-XRD) with synchrotron light, Gas Chromatography/Mass Spectrometry (CG/MS), Optical Microscopy (OM) and Scanning Electron Microscopy (SEM/EDS) were used ...
    • Markers, reactions, and interactions during the aging of pinus resin assessed by Raman spectroscopy 

      Beltran Sanchidrian, Victòria; Salvadó Cabré, Nativitat; Buti Papiol, Salvador; Cinque, Gianfelice; Pradell Cara, Trinitat (2017-04-28)
      Article
      Restricted access - publisher's policy
      The resin extracted from the species of the Pinus genus (Pinaceae family) is a widely used material. Primarily, resins are made up of two types of diterpenoids: abietanes and pimaranes. Their composition changes with aging, ...
    • Micro infrared spectroscopy discrimination capability of compounds in complex matrices of thin layers in real sample coatings from artworks 

      Beltran Sanchidrian, Victòria; Salvadó Cabré, Nativitat; Buti Papiol, Salvador; Cinque, Gianfelice (2015-01)
      Article
      Open Access
      The 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 

      Salvadó Cabré, Nativitat; Buti Papiol, Salvador; Clemente Martínez, Carme; Beltran Sanchidrian, Victòria; Cinque, Gianfelice; Juanhuix, Jordi; Pradell Cara, Trinitat (2018-03-01)
      Article
      Open Access
      Lustering, 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 ...
    • Optimal Sample Preparation for the Analysis of Micrometric Heterogeneous Samples

      Article
      Open Access
      Precise microanalytical techniques are essential in many fields such as cultural heritage materials, showing complex layered microstructures containing a wide range of materials of diverse nature and hardness. Noninvasive ...
    • Vibrational spectroscopies study of Pinus resin in materials from cultural heritage objects 

      Beltran Sanchidrian, Victòria (Universitat Politècnica de Catalunya, 2016-11-21)
      Doctoral thesis
      Open Access
      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 ...
