Observation of Molecular Changes of a Necrotic Tissue from a Murine Carcinoma by Fourier-Transform Infrared Microspectroscopy
2002 / Clinical Cancer ResearchPurpose: Our purpose is to develop infrared (IR) microspectroscopy as a new optical diagnostic tool to support conventional lightscopic techniques in investigating the viability of carcinoma tissues and to develop its use in the evaluation of the early effects of anticancer therapy by monitoring the IR spectra in the necrotic area. Experimental Design: We evalu...

Infrared spectroscopic study on the properties of the anhydrous form II of trehalose. Implications for the functional mechanism of trehalose as a biostabilizer
2001 / Carbohydrate ResearchFTIR spectra were obtained for several different states of trehalose including dihydrate crystal, anhydrous form II (designated by Gil, A. M.; Belton, P. S.; Felix V. Spectrochim. Acta 1996, A52, 1649–1659), anhydrate crystal, dried melt, amorphous solid and aqueous solution. From the observation of the symmetric and antisymmetric stretch vibrations of the gl...

Ambient-dried silica aerogel doped with TiO2 powder for thermal insulation
2000 / Journal of Materials ScienceTwo step-derived SiO2 sol doped with TiO2 powder dissolved in ethanol was prepared. After aging and washing of wet gel, surface modification with TMCS (trimethylchlorosilane) was followed to prevent additional condensation reaction during drying. Ambient-dried SiO2-TiO2gel was heat-treated at various temperatures. The effects of the heat-treated temperature on the ...

Thermal micro ATR/FT-IR spectroscopic system for quantitative study of the molecular structure of poly(N-isopropylacrylamide) in water
1999 / PolymerThe molecular interactions in poly (N-isopropylacrylamide) (PNIPAAM) aqueous solution have been quantitatively investigated by using a newly developed thermal micro attenuated total reflection/Fourier transform infrared (ATR/FT-IR) spectroscopic system. PNIPAAM was prepared by the w/o emulsion method and its lower critical solution temperature (LCST) was examined b...
