Differential scanning calorimetry (DSC) is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. [1]
A highly viscous cubic phase gel made of polysorbate 80, water, and liquid paraffin. Lyotropic liquid crystals result when amphiphiles, which are both hydrophobic and hydrophilic, dissolve into a solution that behaves both like a liquid and a solid crystal. This liquid crystalline mesophase includes everyday mixtures like soap and water. [1] [2]
Petrov was awarded the Freedericksz Medal for outstanding contributions in the field of liquid crystal physics by the Russian Liquid Crystal Society (2004), the Outstanding Contribution to Science Annual Award of the Ministry of Education and Science of Bulgaria (Scientist of the year 2007) and the Marin Drinov Sign of Honour of Bulgarian Academy of Sciences on a ribbon (2008).
Liquid crystals used in dyes and inks often come microencapsulated, in the form of suspension. Liquid crystals are used in applications where the color change has to be accurately defined. They find applications in thermometers for room, refrigerator, aquarium, and medical use, and in indicators of level of propane in tanks.
Superabsorbent polymer: Polymer that can absorb and retain extremely large amounts of a liquid relative to its own mass. [5] Notes: The liquid absorbed can be water or an organic liquid. The swelling ratio of a superabsorbent polymer can reach the order of 1000:1. Superabsorbent polymers for water are frequently polyelectrolytes.
Discotic liquid crystals are mesophases formed from disc-shaped molecules known as "discotic mesogens". These phases are often also referred to as columnar phases . Discotic mesogens are typically composed of an aromatic core surrounded by flexible alkyl chains.
