To fine-tune the zero-point energy difference between the high-spin (HS) and the low-spin (LS) state, external pressure can be used as a tool. The phenomenon of the spin transition, cooperative effects vs. external pressure and the HS -LS relaxation are subjects to be reviewed in this publication with emphasis on the interplay between the internal and the external pressure.</li></ul>http://www.seipub.org/sepacs/PaperInfo.aspx?ID=7163Advances in Chemical Sciencehttp://www.seipub.org/sepacs/PaperInfo.aspx?ID=71632014-03<p class="abstract">A Fiber Optic Reflection-UV/Vis/NIR-System for Non-Destructive Analysis of Art Objects</p><ul><li>Pages 7-14</li><li>Author Wilfried VetterManfred Schreine</li><li>Abstract A fiber optic measuring system for non-destructive pigment analysis using reflection-Ultraviolet/Visible/Near-infrared (UV/Vis/NIR) spectroscopy and its applicability to 19th century watercolor paintings by Moritz M. Daffinger (1790-1849) were presented. The spectra obtained by that system enabled the identification of both organic and inorganic pigments without the risk of damage or contamination of the objects analyzed. Evaluation of the measured spectra was carried out using self-built libraries consisting of reference spectra derived from original 19th century watercolor materials as well as materials of the technical collection of our institute (ISTA). Complementary investigations were carried out with reflection-Fourier transform infrared (FTIR) spectroscopy and X-ray fluorescence (XRF). These spectroscopic measurements facilitated the evaluation of UV/Vis/NIR spectra and strongly improved the reliability of the results. The results obtained allowed not only the identification of materials but also statements regarding the specific paint technique of the artist.</li></ul>http://www.seipub.org/sepacs/PaperInfo.aspx?ID=11143Advances in Chemical Sciencehttp://www.seipub.org/sepacs/PaperInfo.aspx?ID=111432014-03<p class="abstract">Nano and Microspheres of Poly(aniline-formaldehyde): A Simple Synthesis</p><ul><li>Pages 15-18</li><li>Author Palaniappan SrinivasanSaravanan ChandrasekaranVenkateshwar Myakal</li><li>Abstract Nano and microspheres of novel poly (aniline-formaldehyde) [PANiFd] were synthesized through a simple mixing procedure using metal chlorides (FeCl3+AlCl3) under static condition.</li></ul>http://www.seipub.org/sepacs/PaperInfo.aspx?ID=9766Advances in Chemical Sciencehttp://www.seipub.org/sepacs/PaperInfo.aspx?ID=9766
