Plastic crystals are currently attracting interest because their solid-state caloric functionality
could be used to tackle climate change in two critical areas:(i) more environmentally friendly …

Disorder–disorder phase transitions are rare in nature. Here, we present a comprehensive
low-temperature experimental and theoretical study of the heat capacity and vibrational …

Phase transitions in crystalline molecular solids have important implications in the
fundamental understanding of materials properties and in the development of materials …

In this review, the analysis of solid-solid phase transitions between crystalline polymorphs of
organic molecules is discussed. Although active pharmaceutical ingredients (APIs) are the …

We report a crystal structure of Boc-l-methionyl glycine methyl ester (MGP) with eight
molecules in the asymmetric unit (Z′= 8), which is the highest number in dipeptide …

We present an ultrasonic study of the elastic properties of 1-X adamantane (X= F, Cl, Br)
during order–disorder and order–quasi-order transitions at various temperatures (77–305 K) …

The polymorphic behavior at normal pressure as a function of temperature of 2-adamantanol
(C10H16O) and 2-methyl-2-adamantanol (C11H18O) has been investigated by single …

Optical fibers provide a favorable medium for nonlinear optical processes owing to the small
mode field size and concurrently high optical intensity combined with the extended …

Two polytypes of the new oxyvanadate matrix La7O6 (VO4) 3 were identified and deeply
characterized. The crystal structure of the α-polytype was solved using a combination of …

It is shown that the presence of hundreds of ppm of water in 1, 3-dimethylurea (DMU)
powder led to the large depression of the transition temperature between the two …
