Infra-red and Raman Spectroscopic Studies of Infected and Affected Dentine
Diagnosis of infected and affected dentine is an important factor in clininal restorative treatment of dentine. In this study, the IR and Raman spectra of the sound dentine, infected dentine and affected dentine are reported. The structure of infected dentine and affected dentine has been compared with the sound dentine and hydroxyapatite. It is shown while the infected dentine has lost its...
متن کاملRaman Spectroscopic Studies of Bioactive Materials
Bioactive materials including glass and glass-ceramics are nowadays used as medical implants for orthopedic applications. In this study several samples of glass-ceramics have been prepared using both heat treatment and sol-gel processes. The structure and bioactivity of these samples based on their interaction with simulated body fluid (SBF) have been determined. In-vitor, using the Raman s...
متن کاملTwo-dimensional Manganese(II) Coordination Polymer Complex Containing Aqua, Diethyl Phosphate and Chloride Ligands: Synthesis, Spectroscopic Characterization, Thermal Analyses, and Crystal Structure
A new two-dimensional manganese(II) coordination polymer, [Mn(μ-DEP)(μ-Cl)(H2O)2]n (1) (DEP is diethyl phosphate), was prepared from the reaction of MnCl2.4H2O and TEP (TEP is triethyl phosphate) ligand in mixture of H2O/CH3OH (1:10) at 40 °C. Suitable crystals of this complex for crystal structure determination were obtained by slow evaporation of the produced colorless solution at room temper...
متن کاملSynthesis, Characterization, and Crystal Structure Determination of Iron(III) Hetero-ligand Complex Containing Chloride, Dimethyl sulfoxide, pyridine-2, 6-dicarboxylate and Water, [Fe(Pydc)(DMSO)(H2O)Cl]
A new metal-organic compound, [Fe(Pydc)(DMSO)(H2O)Cl], (where Pydc is pyridine-2, 6-dicarboxylate and DMSO is dimethyl sulfoxide), has been synthesized and characterized by singlecrystal X-ray diffraction, TGA/DTA, IR and Raman spectroscopy. Green-yellow crystals,crystallized in the monoclinic system, space group P21/n, a = 7.2461(4) Å, b = 10.3018(4) Å, c =17.7667(10) Å, α = 90°, β = 90.014°(5...
متن کاملNoninvasive assessment of the hydration gradient across the cornea using confocal Raman spectroscopy.
PURPOSE The feasibility of Raman spectroscopy for the noninvasive assessment of axial corneal hydration was investigated. METHODS A scanning confocal Raman spectroscopy system, with an axial resolution of 50 microns, was used to assess noninvasively the water (OH-bond) to protein (CH-bond) ratio as a measure of the hydration in collagen-based phantom media and rabbit corneas. RESULTS Raman ...
