Micro Infrared Spectroscopy (µSR-FTIR) and X-Ray diffraction (µSR-XRD) with synchrotron light, Gas Chromatography/Mass Spectrometry (CG/MS), Optical Microscopy (OM) and Scanning Electron Microscopy (SEM/EDS) were used to identify and obtain the distribution of complex mixtures of calcium salts of low molecular weight organic acids (LMWOA) in micro-layered micro-samples. Filamentous fungi produce LMWOA that can react with metal cations producing stable salts. These substances were found in the dark spots covering the surfaces of Saint Michael's Chapel wall paintings of the Royal Monastery of Pedralbes in Barcelona linking them to old fungi activity. The presence of glycerol likewise related to the fungi activity is also identified in the layers.

“…Optical quality single crystals of appreciable size can be grown by the controlled diffusion of the appropriate ionic species in a neutral gel matrix. Using this method, we have succeeded in growing good crystals of a few malates [9][10][11], malonates [12][13] and maleates [14][15][16]. In this paper, we report for the first time, the growth of crystals of appreciable size by the coordination of malic acid with barium.…”

“…The crystals formed by the coordination of various metals with certain dicarboxylate ligands like oxalates, malonates and maleates are found to possess immense potentials in the realms of magnetism and non linear optics. Due to the outstanding properties exhibited by the above class of materials, recently we have grown certain metal malates of fairly good size using limited diffusion media [1]. This paper is a report on the structural, thermal and dielectric properties of cadmium malate crystals grown in hydrosilica gel.…”

Abstract. Single crystals of cadmium malate trihydrate have been grown by the controlled diffusion of ionic species in hydrosilica gel. Single crystal X-ray diffraction studies show that the crystal belongs to the monoclinic system with space group P2 1 /n. The functional groups elucidated from the FTIR spectrum are in conformity with the information derived from the Xray diffraction studies. The thermal behaviour of the material has been investigated using TG-DTA techniques. The optical band gap of the material has been estimated using diffuse reflectance spectroscopy. The dielectric constant, dielectric loss and a.c. conductivity of the crystal are studied over wide temperature and frequency ranges.
