`The investigation of solid forms of organic compounds and its structural characterization is an area of active research. It is particularly relevant in what concerns active pharmaceutical ingredients [1, 2], but also in all other domains where differences in the solid-state form may impact the material properties [3, 4]. Polymorphs of the pure compound, solvates, salts, co-crystals and their...

`Glassy matrices for the encapsulation and stabilization of bioactive compounds often consist of molecularly miscible blends of a carbohydrate of higher molecular weight and a low molecular weight carbohydrate or polyol. Typical examples of such blends are maltodextrin/sucrose and trehalose/glycerol. The optimization of the barrier properties of such matrices depends in a subtle way on the...

`Investigations on the development of strategies for a more rational synthesis of new materials with desired physical properties is still a major field in modern chemistry. This approach, called “crystal engineering”, includes systematic investigations on the structure property relationships of compounds as well as ideas how a given structure can specifically be prepared. In this context,...

Soft matter and glass formers
oral presentation
`Positron annihilation lifetime spectroscopy (PALS) has been employed for characterization of the local structure in molecular substances such as polymers or liquid crystals. When a positron enters an insulator solid it can form a bound state with an electron called positronium (Ps). Ps is located in low electron density regions like local free volume holes. Ps can be formed in two spin...

Soft matter and glass formers
oral presentation
`Liquid crystalline compounds belonging to 3FmHPhF homologous series (m = 2, 4, 5, 6, 7) have been studied by complementary methods such as differential scanning calorimetry (DSC), polarizing optical microscopy (POM), electrooptic methods, frequency domain dielectric spectroscopy (FDDS) and X-ray diffraction (XRD). All studied compounds exhibit ferroelectric smectic C$^\ast$ and...
