In this study, tretinoin microemulsion has been formulated based on phase diagram studies by changing the amounts and proportions of inactive ingredients, such as surfactants, co-surfactants and oils. The effects of these variables have been determined on microemulsion formation, particle size of the dispersed phase and release profile of tretinoin from microemulsion through dialysis membrane. ...

Direct ink writing (DIW) requires careful selection of composition with specific rheological properties, and it has limitations, such as the inability to create overhanging parts or branched geometries. This study presents an investigation into enhancing 3D printing process through use a heterophase system, aiming overcome these limitations. A modification was carried out in printer constructio...

Nanofluids are used as coolants in heat transport devices like exchangers, radiators, and electronic cooling systems (like a flat plate) because of their improved thermal properties. The preeminent perspective this study is to highlight the influence combined convection on transfer pseudoplastic non-Newtonian nanofluid flow towards an extendable Riga surface. Buongiorno model incorporated prese...

In this paper, we study the influence of heat sink (or source) on the peristaltic motion of pseudoplastic fluid in the presence of Hall current, where channel walls are non-conducting in nature. Flow analysis has been carried out under the approximations of a low Reynolds number and long wavelength. Coupled equations are solved using shooting method for numerical solution for the axial velocity...

The effective modeling of fresh cementitious materials during setting is an active and challenging research topic. material behavior as well the parameters properties are not fully understood yet. Therefore, flow casting subject ongoing research. Previous works attempted to model cement paste a solid subjected yielding, or fluid modeled by Brinkman law power law, both in 2D 3D. Of existing mode...

In the present study, static characteristics of hydrodynamic circular journal bearings finite length are highlighted, using combined influences textured surface and non-Newtonian lubricants behavior, obeying to Rabinowitsch fluid model. The associated nonlinear Rabinowitsch-Reynolds equation has been discretized differences scheme solved by mean Elrod’s algorithm taking into account presence cy...
