3.5.3 X-Ray Diffractometery (XRD). The crystallinities of pure Zolmitriptan‚ excipients and liquisolid system were evaluated by XRD measurement. It has been seen that polymorphic changes of the drug are important factors‚ which may affect the drug dissolution rate and bioavailability(135). The X- ray diffractogram of pure Zolmitriptan Figure (25) exhibited several sharp peaks at different angle (2Ɵ)‚the three strongest angles were 19.2 Ɵ‚ 21.9 Ɵ and 23.8 Ɵ ‚other angles were 12.2 Ɵ‚13.7 Ɵ‚ 14.2

TERMPAPER TOPIC:- imperfection in solid’s NAME:-MILAN RAJAWAT Regd. No.:-11004886 Section:-M2R16 Roll No.:-B16 Subjet:-MEC208 INTRODUCTION For a crystalline solid we have tacitly assumed that perfect order exists throughout the material on an atomic scale. However‚ such an idealized solid does not exist; all contain large numbers of various defects or imperfections. As a matter of fact‚ many of the properties of materials are profoundly sensitive to

Preparation and Ferroelectric Characterization of Calcium doped Barium Titanate ceramics ABSTRACT Barium Titanate (BT) is widely used in electro-optical and electroceramic industry because of its ferroelectric‚ thermoelectric and piezoelectric properties when it assumes the tetragonal structure. In addition to its Lead free composition‚ its perovskite structure allows variation of ionic size and small displacement of atoms that lead to the distortion of the structure which has a profound

Hey I just met you‚ and this is crazy‚ but heres my number‚ so call me maybe. Pointless scores all the possible Laue groups consistent with the crystal class‚ which is based on cell dimension restraints. It does this by matching potential symmetry equivalent reflections. For chiral systems‚ the Laue group uniquely implies the point group. It then checks sets of reflections which may be systematically absent to suggest a possible spacegroup. There is also a check for lattice centering‚ ie a check

A mineral is any naturally occurring‚ inorganic substance‚ often additionally characterized by an exact crystal structure. Its chemical structure can be exact‚ or can vary within limits. Minerals possess a number of properties that are used as an aid in their identification just like color‚ luster‚ streak‚ cleavage‚ hardness‚ specific gravity‚ and even by their chemical properties‚ composition‚ Hardness‚ Crystal Form‚ Electrical Properties and Melting Points. Here I got a mineral as shown in the

SOLID STATE MARKS = 04 SOLID STATE A solid is that form of matter that possesses a definite shape and a definite volume. There are two types of solids: Crystalline solids: Solids with a definite geometric pattern and are anisotropic in nature. Examples: Iron‚ copper‚ silver‚ sulphur etc. are some elements which form crystalline solids. Potassium chloride‚ sodium nitrate etc are some of the compounds‚ which are crystalline
