1e). These indicate the presence of several polymorphs of Si. The dark-field image taken by using three bright reflections of such newly identified tetragonal polymorphs (indicated in the ...

Solids tend to be ordered and different spatial three-dimensional arrangements of the same molecules can give us different crystal structures, so different polymorphs. Polymorphism is a tendency ...

Raman technology has excellent spectral specificity and serves as a useful tool in identifying different forms of polymorphs. In addition, it can be utilized for studying the solvate forms including ...

In the journal Angewandte Chemie ("Using Magnetic Levitation to Separate Mixtures of Crystal Polymorphs"), they have now demonstrated the extraordinary efficiency of separation through “magnetic ...

Both Synthon and SmithKline Beecham sought patents for the production of polymorphs known as paroxetine mesylate. However, a similar problem cropped up shortly after. Any attempt to create the ...

Small molecule drugs have formed most pharmaceutical discoveries for over a century, however, approximately 40% of current active pharmaceutical ingredients (APIs) are poorly soluble, along with ...

Detecting the Presence of Trace Polymorphs and Impurities One of the key uses of PXRD in the pharmaceutical industry is detecting the presence of polymorphs. The increasing requirement for more ...

Sulfathiazole, a valuable antimicrobical sulfa drug used in veterinary medicine (see Figure 1), was chosen for this study mainly because of its commercial value and its five polymorphs, which are well ...

Identifying polymorphs is a crucial part of the drug-development process as researchers forward select methods to improve detection. Screening and detecting polymorphism when developing and ...
