Resolution of 9,10-Diketo[7]helicene and Its Use in One-Step Preparation of Helicene-Based D−A−D Push-Pull Systems

Research of chiral push-pull systems based on helicenes continues successfully in the Group of Advanced Materials and Organic Synthesis (GAMOS). This type of molecules, containing one or more electron-rich (donor, D) and electron-deficient (acceptor, A) groups directly connected to the π-system of helicene, is suitable for the preparation of lumin…

Synthesis and Unexpected Binding of Monofluorinated N,Nʹ-Diacetylchitobiose and LacdiNAc to Wheat Germ Agglutinin

Wheat germ agglutinin (WGA) is a carbohydrate-binding protein (lectin) abundant in the seeds of common wheat. WGA is used as a model lectin to elucidate the principles governing carbohydrate-lectin interactions. Moreover, WGA acts as a fungistatic, cytotoxic, or antiviral agent with potential in various biomedical applications. For example, WGA dis…

Capillary condensation between nonparallel walls

Capillary condensation is a well-known example of finite-size effects referring to a shift in the condition for condensation of fluids confined by solid walls. The phenomenon is ubiquitous in nature and plays an important role in many technological applications. Although well-described for simple models (e.g., planar or cylindrical geometry), the p…

Bulk fluidity and apparent wall slip of deflocculated kaolin suspensions

Apparent wall slip (AWS) is an interphase phenomenon which describes a specific boundary conditions when a dispersion flows along a wall. AWS is caused by dispersion-wall interaction (spatial reasons, electrostatic interactions) and can be either positive (formation of depleted layer apparently amplifies flow intensity) or negative (formation of st…

Kelvin equation for bridging transitions

If two solid surfaces immersed in a fluid get sufficiently close together, a local condensation between them may occur. These so-called bridging transitions, referring to the formation of a liquid film connecting the surfaces, depend sensitively on their shape. The theoretical study led by Prof. Alexandr Malijevský and published in Physical Review…

Modular synthesis of dendritic ionic triphiles and their behavior in three-phase liquid–liquid–liquid system

Triphiles are a narrow group of substances exhibiting unique properties due to the presence of three incompatible parts of the molecule (domains) – oleophilic, hydrophilic, and fluorophilic. For example, triphilic ionic liquids form fascinating crystalline lattices, and triphilic copolymers form micelles with a compartmentalized lipophilic co…
