An FTIR study of the complex melting behavior of alpha-lactalbumin
Article Abstract:
A study was conducted to analyze the thermal denaturation of holo alpha-lactalbumin (alpha-LA) using Fourier transform infrared spectroscopy. The absorbance of protein bands in the secondary structure sensitive amide I region was examined. Results indicated that the beta-hairpin of alpha-LA is not directly stabilized by the bound calcium ion present in the holo protein. Findings also showed that it melts independently from the rest of the protein.

FTIR spectroscopy of alcohol and formate interactions with mesoporous Ti[O.sub.2] surfaces
Article Abstract:
The effects of pH and ultraviolet (UV) light with ligated formic acid on mesoporous Ti[O.sub.2] are characterized by transmission fourier transform infrared (FTIR) spectroscopy and compared with adsorbed formate complexes. Results show a major difference between the type of complexes of formic acid formed directly on an anatase surface due to photocatalytic oxidation and that formed by the adsorption of formic acid from aqueous solution.

Conformational behavior of poly(L-lactide) studied by infrared spectroscopy
Article Abstract:
The conformational changes observed in both crystalline and amorphous poly(L-lactide) (PLLA) samples are investigated by FTIR spectroscopy. The bands corresponding to gt, gg and tt conformers in amorphous PLLA can be resolved by second derivative techniques and curve-fitting results provide information about the conformational population at different temperatures.
