Organic molecules, such as pharmaceuticals, agro-chemicals and pigments, frequently form several crystal polymorphs with different physicochemical properties. Finding polymorphs has long been a ...

Similar to polymorphs, we find that amorphous materials can take on several modifications; this is called polyamorphism. Why is the solid form of a drug so important to the pharmaceutical industry?

Materials can have varying polymorphic forms, meaning that the crystal structure can differ, even though the chemical composition is the same. Polymorphs occur in both organic and inorganic materials, ...

When high-velocity asteroids land on Earth, they can form a meteor impact crater. Such collisions have occurred throughout ...

This image by Shaista Hassan Lone, a scientist at the University of Kashmir, shows two polymorphs—different crystal structures—of 4-(dimethylamino)benzaldehyde. When Lone initially set out to ...

Yet "finding new polymorphs is currently rather hit-and- miss," says assistant professor of chemistry Adam J. Matzger of the University of Michigan, Ann Arbor. Three years ago, Matzger and ...

Polymorphs, or different crystalline forms of the same drug, can be selected for distinct properties and patented. A recent court ruling, however, adds new complexity, write experts at Finnegan.
