Nanopore and nanoparticle formation with lipids, undergoing polymorphic phase transitions
Diana Cholakova, Desislava Glushkova, Slavka Tcholakova +1
We describe several unexpected phenomena, caused by a solid-solid phase transition (gel-to-crystal) typical for all main classes of lipid substances - phospholipids, triglycerides,…
Origin of the extremely high elasticity of bulk emulsions, stabilized by Yucca Schidigera saponins
Sonya Tsibranska, Slavka Tcholakova, Konstantin Golemanov +4
We found experimentally that the elasticity of sunflower oil-in-water emulsions (SFO-in-W) stabilized by Yucca Schidigera Roezl saponin extract, is by more than 50 times higher as…
Role of interfacial elasticity for the rheological properties of saponin-stabilized emulsions
Sonya Tsibranska, Slavka Tcholakova, Konstantin Golemanov +3
Hypothesis Saponins are natural surfactants which can provide highly viscoelastic interfaces. This property can be used to quantify precisely the effect of interfacial dilatational…
Foamability of aqueous solutions: Role of surfactant type and concentration
B. Petkova, S. Tcholakova, M. Chenkova +4
In this paper we study the main surface characteristics which control the foamability of solutions of various surfactants. Experiments with anionic, cationic and nonionic surfactan…
Food grade nanoemulsions preparation by rotor-stator homogenization
Dilek Gazolu-Rusanova, Ivan Lesov, Slavka Tcholakova +2
High-pressure homogenizers, typically used for producing nanoemulsions at the industrial scale, are energy and maintenance intensive, and limited to produce only dilute, low viscos…
Spontaneous particle desorption and "Gorgon" drop formation from particle-armored oil drops upon cooling
Diana Cholakova, Zhulieta Valkova, Slavka Tcholakova +2
Drop "self-shaping" is a phenomenon in which cooled oily emulsion drops undergo a spectacular series of shape transformations (Denkov et al., Nature 528, 2015, 392). Solid particle…
