`In the last years, MgO-based cementitious materials have attracted great interest as eco-sustainable alternatives to traditional Portland (CaO-based) cement, the dominant form of cement used worldwide. In particular, MgO-based formulations have been proposed with the aim of both reducing the environmental footprint associated with the production of Portland cement and developing cements to be...

`A family of 4-alkyl-4’-cyanobiphenyl ($n$CB, $n$ is the number of carbon atoms in the alkyl chain) is one of the most famous mesogenic series of calamitic molecules. The $n$CBs exhibit liquid crystalline phases, nematic (N) and smectic A$_\mathrm{d}$ (SmA$_\mathrm{d}$, d means dimer) phases, below the isotropic liquid (IL) depending on the length $n$ of the alkyl chain. Although a huge number...

`Chiral liquid crystals form macroscopic helicoidal structure. It is characterized by two parameters: the value of helical pitch and the helical twist sense (handedness). Spectroscopy methods let measure both of these parameters. The helical pitch can be measured actually by different methods, but the most popular method uses UV-Vis-IRspectrophotometers. The idea of measurement is based on the...

`Spectrum of a dielectric permittivity for supercooled disordered phases most often is composed of two relaxation processes [1]: a main relaxation process (called $\alpha$ process) followed by resolved, unresolved (also called ‘excess wing phenomena’), or both secondary processes ($\beta$ processes). Although there are many models describing dielectric relaxation [2-6] none of them describes...

`Presented research concerns the investigations of vitrification and crystallization processes in 4CFPB (4-cyano-3-fluorophenyl 4-butylbenzoate) liquid crystalline substance. Glass transition is important issue in new-day condensed matter physics. Additionally, cold crystallization phenomenon is also interesting case, especially in connection to glass formation tendency. Descriptions of both...
