Hierarchically structured surfaces including sensitive materials presents the advantage to exalt wettability variation due to the combination of micro structure effect directed by Cassie Baxter and/or Wenzel behaviour which is tuned by the surface energy variation of sensitive polymer films. Herein is reported the synthesis and the hierarchical str...

Chitosan has been modified in order to produce nanoparticles with promising characteristics in diverse food applications, e.g. Pickering emulsions. Chitosan deprotonation and ionic crosslinking with tripolyphosphate were assessed in this work. Chitosan nanoparticles produced by these two methods were characterized according to surface charge, parti...

Pickering emulsions, which are emulsions stabilized by solid particles, have gained increased research interest owing to their eco-friendliness and high stability. Among a wide range of solid particles, chitosan particles and chitosan-based particles have become attractive candidates as Pickering stabilizers due to their biodegradable, biocompatibl...

This study examined the physical and chemical properties of engine oil with a submicron-sized carbon particle lubricant mixture. Spherical carbon particles were added to engine oil to lower the friction and wear losses. In the current study, morphological and chemical analyses of these carbon particles were performed using field emission scanning e...

AbstractIn the present study, the different weight ratios of 7-hydroxy-4-methyl coumarin (7H4MC) mixed polyvinyl alcohol (PVA)/oxidized maize starch (OMS) blend films were achieved by the solvent casting method and coded as PSC. The prepared film samples were characterized by employing techniques such as FTIR, UTM, and SEM. The film samples were al...

Wettability is usually measured in special core analyses of limited plug samples according to typically costly and time-consuming procedures. For comparative purposes, wettability is considered an index. The two most frequently used wettability indices are the Amott–Harvey wettability index and the U.S. Bureau of Mines (USBM) index. The Amott–Harve...

Static shape of liquid droplets on textured surface draws significant attention from the standpoint of several engineering applications, ranging from heat transfer to bio-printing. This paper discusses the equilibrium behavior of a nanoliter size droplet dispensed on a micropatterned surface. For a given combination of intrinsic wettability of the ...

Most probiotic-based products are available in powder particles under different solid-state forms. Such diversity can affect the probiotic stability, viability, and performance at different stages of processing, storage, and use. Here, we apply complementary physical chemistry techniques to characterize the bulk and surface properties of probiotic ...
