Trans-dehydrocrotonin has antiulcerogenic and antitumor activities. A complex of beta-cyclodextrin with dehydrocrotonin was developed to improve the delivery of dehydrocrotonin. Complex in solid state was evaluated using X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermal gravimetric analysis (TGA) and scanning electron microscopy (SEM). X-ray diffraction and scanning elec...

A new ligand containing long alkyl (octadecyl) chains was used to obtain the mesogenic complex [L2Cu4(mu4-O)(OAc)4].EtOH (1). This complex was thoroughly characterized and had its molecular structure solved by X-ray diffraction (XRD). Mesomorphic properties were demonstrated by means of polarized microscopy, differential scanning calorimetry, and XRD.

Proper characterization is an important aspect of any dosage form design. The objective of this work was to characterize tannate salt and hydrochloride salt of diphenhydramine. As a part of characterization studies, Differential scanning calorimetry was used to investigate thermal effects and nature of salts, supported by X-ray powder diffraction. Scanning electron microphotographs was used to ...
