    • Assessment of synthetic polymeric coatings for the protection and preservation of stone monuments 

      Tsakalof, A.; Manoudis, P.; Karapanagiotis, I.; Chryssoulakis, I.; Panayiotou, C. (2007)
      The performance of five synthetic coatings for the protection of stone monuments of Hellenistic and Byzantine period has been evaluated. The selected coatings included four commercially available siloxane-, siloxane/acrylic- ...

    • Fabrication of super-hydrophobic surfaces for enhanced stone protection 

      Manoudis, P. N.; Tsakalof, A.; Karapanagiotis, I.; Zuburtikudis, I.; Panayiotou, C. (2009)
      In the current study, we demonstrate that the modification of a commercial siloxane protective composition by the addition of silica nanoparticles substantially enhances its protective efficiency and renders the treated ...

    • Identification of red natural dyes in post-byzantine icons by HPLC 

      Karapanagiotis, I.; Daniffia; Tsakalof, A.; Chryssoulakis, Y. (2005)
      A high performance liquid chromatography (HPLC) methodology, combined with UV-Vis Diode Array Detection, is developed for the separation and identification of five reddish natural dyestuffs: cochineal, madder, lac dye, ...

    • Polymer-Silica nanoparticles composite films as protective coatings for stone-based monuments 

      Manoudis, P.; Papadopoulou, S.; Karapanagiotis, I.; Tsakalof, A.; Zuburtikudis, I.; Panayiotou, C. (2007)
      The decrease of surface energy of mineral substrates similar to those used in many stone monuments of cultural heritage by the application of protective polymer coatings along with the simultaneous increase of their surface ...

    • A simple methodology for producing super-hydrophobic composite films on various substrates 

      Manoudis, P. N.; Karapanagiotis, I.; Tsakalof, A.; Zuburtikudis, I.; Panayiotou, C. (2008)
      Various nanoparticles (silicon oxide, tin oxide and aluminium oxide) were mixed with poly (methyl siloxane) (Rhodorsil 224). The mixtures were sprayed on silicon substrates resulting in the formation of a rough, two-length-scaled ...

    • Superhydrophobic composite films produced on various substrates 

      Manoudis, P. N.; Karapanagiotis, I.; Tsakalof, A.; Zuburtikudis, I.; Panayiotou, C. (2008)
      Hydrophilic silica NOD nanoparticles were dispersed in solutions of poly(methyl methacrylate) (PMMA) and in solutions of a commercial poly(alkyl siloxane) (Rhodorsil 224), and the suspensions were sprayed on glass surfaces. ...

    • Superhydrophobic films for the protection of outdoor cultural heritage assets 

      Manoudis, P. N.; Karapanagiotis, I.; Tsakalof, A.; Zuburtikudis, I.; Kolinkeova, B.; Panayiotou, C. (2009)
      A very simple method that can be used to impart superhydrophobicity to stone surfaces of monuments using common and low-cost materials that are already employed or are easy to be found by conservators is presented. A ...

    • Surface Properties of Superhydrophobic Coatings for Stone Protection 

      Manoudis, P. N.; Karapanagiotis, I.; Tsakalof, A.; Zuburtikudis, I.; Kolinkeova, B.; Panayiotou, C. (2009)
      Superhydrophobic films are produced by a simple and low cost method. Silica (SiO(2)) nanoparticles are dispersed in solutions of Rhodorsil 224, a commercial poly(alkyl siloxane) which is used for the protection of outdoor ...
