Background Several reports have focused on the value and biological transformation of industrial wastes as an alternative substrate for the production of high value-added components. In this context, it can cite the crude residual glycerin obtained as the primary byproduct of biodiesel production, which has increased exponentially during the last years. As an abundant residue, its disposal into...

In the current literature, information can mainly be found about free and hindered settling of isometric particles in Newtonian non-Newtonian fluids. These conclusions cannot used to describe sedimentation non-isometric particle For this reason, we have carried out systematic experiments calculated correlation velocity a cloud high-viscosity pseudoplastic liquid. The were performed transparent ...

ABSTRACT Fruit pulps undergo temperature variations during processing, leading to viscosity changes. This study aimed analyse the rheological behaviour of macaíba pulp at different temperatures (10 50 ºC, with 5 ºC increments) and speeds (2.5 200 rpm, totalling 17 speeds). Experimental measurements were performed in a Brookfield viscometer, fitting Ostwald-de-Waele, Mizrahi-Berk, Herschel-Bulkl...

Nanocapsule suspensions containing coenzyme Q10 were prepared by interfacial deposition. The nanocapsules showed characteristics compatible with dermal application: slightly acid pH, drug content close to 100%, particle size between 213 and 248 nm with low polydispersity and negative zeta potential. Three cosmetic formulations for skin application were developed, one with the free-coenzyme Q10,...

Drilling fluid plays the same role in oil and gas well drilling as blood human body. A new type of oil-in-water (o/w) emulsion has been developed using diesel dispersed phase, brine water continuous xanthan gum viscosity modifier clay stabilizer filtration controlling agent. Initially, standard recommended techniques were opted to detect rheological properties emulsions. The fluids have also sh...

Lentinan (LNT) is extracted from the fruiting body of Lentinus edodes. Its active ingredient β−1,3-dextran and has many biological activities, but its rheological characteristics antibacterial mechanism when mixed with saliva are rarely reported. In this study, LNT artificial (AS) mixture was used to investigate analysis against Streptococcus mutans (S. mutans). The results showed that apparent...

The purpose of this study was to develop a pH-triggered in situ gelling vehicle for ophthalmic delivery of puerarin. The effect of hydroxypropyl-beta-cyclodextrin (HP-beta-CD) on the aqueous solubility and in vitro corneal permeation of puerarin was also investigated. The puerarin solubility increased linearly and proportionally to the HP-beta-CD concentrations and 5% (w/v) HP-beta-CD enhanced ...
