It has been shown that structured lipids, formed in the process of enzymatic modification natural hard fat with walnut oil, are capable stabilizing emulsion systems without need to add additional emulsifiers. This is especially true for emulsions containing during when amount added water reaction catalyst was range 12–16 wt%. Physicochemical evaluations, i.e., average particle size, its growth,...

The thixotropy of cellulose nanocrystal (CNC) water suspensions is intrinsically dependent on the hierarchical structure suspension. diverse hierarchies that comprise individual CNC nanoparticles and mesophase liquid crystalline domains, chiral nematic structures, contribute selectively to rheological material response. Here, we combine rheology with polarized light imaging (PLI) elucidate thix...

Mucoadhesive gelling systems with tannic acid modified silver nanoparticles were developed for effective treatment of herpes virus infections. To increase nanoparticle residence time after local application, semi solid formulations designed from generally regarded as safe (GRAS) excipients were investigated for their rheological and mechanical properties followed with ex vivo mucoadhesive behav...

In contrast with simple liquids such as water, milk, honey, which easily flow as a continuous jet when poured from a vessel, pasty materials such as mayonnaise, mustard, ketchup, puree, etc., fall by fits and starts in a wide range of flow rates. This may, for example, be observed when ketchup or mayonnaise is pushed from a tube at a sufficient height over a plate: although surface tension effe...

For more than 20 years it has been debated if yield stress fluids are solid below the yield stress or actually flow; whether true yield stress fluids exist or not. Advocates of the true yield stress picture have demonstrated that the effective viscosity increases very rapidly as the stress is decreased towards the yield stress. Opponents have shown that this viscosity increase levels off, and t...

An asphalt mastic has thixotropic characteristics that significantly influence its fatigue and healing performance. Therefore, understanding the thixotropy of an is clearly great importance. However, research in this area still early stages. This study focuses on self-heating as one biasing performances material by analyzing viscosity, stress, hysteresis loops mastics under cyclic shear loading...
