Spectral damage model for lighted museum paintings: Oil, acrylic and gouache
SM Pinilla, D Vázquez, AÁ Fernández-Balbuena… – Journal of Cultural Heritage, 2016 A spectral aging test was developed to estimate the photochemical damage of oil, acrylic and gouache paints exposed to permanent lighting. The paints were irradiated at seven...Investigation of upconversion luminescence in Yb3+/Tm3+/Ho3+ triply doped antimony-germanate glass and double-clad optical fiber
J Zmojda, M Kochanowicz, P Miluski, GC Righini… – Optical Materials, 2016 The optical properties of novel antimony-germanate glass and optical fiber co-doped with Yb3+/Tm3+/Ho3+ ions were presented. White light luminescence in glass was observed as a result of...Inactivation of Asterionellopsis glacialis in seawater using combinations of deep ultraviolet light emitting diodes
M Rantalankila, H Koivistoinen, L Sarvasidze… – Separation and Purification …, 2016 Deep ultraviolet light emitting diodes (LED) were studied in water disinfection using Asterionellopsis glacialis as a model microorganism. Ultraviolet treatment reactors were...MEASUREMENT OF NITRATE-NITROGEN CONCENTRATION IN SOIL BASED ON ABSORPTION SPECTROSCOPY
MJ Preiner, NC Koshnick, JS White, JP Strachan – US Patent 20,160,146,728, 2016 The nitrate-nitrogen concentration in soil is estimated based on the nitrate-nitrogen 200 nm absorption peak. In one embodiment, a device measures the attenuation spectrum of a...Optical fiber sensor for low dose gamma irradiation monitoring
AI de Andrés, Ó Esteban, M Embid – Sixth European Workshop on Optical Fibre …, 2016 An optical fiber gamma ray detector is presented in this work. It is based on a Terbium doped Gadolinium Oxysulfide (Gd2O2S:Tb) scintillating powder which cover a chemically...Introducing our new Applied Spectroscopy Division
