Surfactant proteins (SP)-A and SP-D are collagen-like glycoproteins belonging to the "collectin" class of C-type lectins, which are primarily synthesized in type II cells. Recent studies reported the possibility of local production of SP-A and SP-D in the airways, but the amounts of surfactant proteins in patients with bronchial asthma have not been studied. The composition of surfactant protei...

Aim and objective: The purpose of this study was to develop microemulsion formulations for topical delivery bifonazole with an objective increase the solubility drug. Methods: Total 5 were developed using water titration method. Capmul Pg-12 (oil), Tween-80: (surfactant) Propylene glycol (co-surfactant) used in different ratio based on emulsification efficiency. Prepared evaluated parameters li...

A dispersed nano-system with droplet sizes as small submicrons is called a nanoemulsion. Nanoemulsions are thermodynamically stable, transparent, isotropic liquid mixtures of oil, water, surfactant, and co-surfactant. Nanoemulsion typically has between 20 200 nanometer. The size composition the scattered particles in continuous phase primary distinctions an emulsion This approach intended to al...

Polymer-clay nanocomposites (PCNCs) containing either a rubber or an acrylate polymer were prepared by drying or co-precipitating polymer latex and nanolayered clay (synthetic and natural) suspensions. The interface between the polymer and the clay nanoparticles was studied by electron paramagnetic resonance (EPR) techniques by selectively addressing spin probes either to the surfactant layer (...

The aim of the study was to develop and evaluate a self--emulsifying drug delivery system (SEDDS) formulation to improve solubility and dissolution and to enhance systemic exposure of a BCS class II anthelmetic drug, albendazole (ABZ). In the present study, solubility of ABZ was determined in various oils, surfactants and co-surfactants to identify the microemulsion components. Pseudoternary ph...

Abstract Studies performed by Burns et al. in 2021 and 2022 demonstrated that a three‐stage batch‐wise adsorptive bubble separation process, surface active foam fractionation (SAFF), is effective at removing most per‐ polyfluoroalkyl substances (PFASs) from contaminated groundwaters landfill leachates. However, PFAS species with very low adsorption coefficients to surfaces are difficult remove,...

The aim of the current study was to design an self-nanoemulsified drug delivery system (SNEDDS) of docetaxel by optimizing the particle size using response surface methodology. SNEDDS were prepared using surfactant, co-surfactant and oils/co-solvents. A IV optimal design for 3 factors at 3-level each was employed systematically optimize particle size. The particle size was taken as dependent va...

The influence of particle size in the carbon monoxide hydrogenation reaction has been studied using cobalt nanoparticles (NPs) with narrow size distribution prepared from colloidal chemistry. The surfactant covering the NPs after synthesis could be removed by heating to 200-270 degrees C in H(2). Soft X-ray absorption spectroscopy was performed using a gas flow cell under reaction conditions of...

We report the presence of a correlation between the bulk and interfacial properties of electrostatic coacervate complexes. Complexes were obtained by co-assembly between cationic-neutral diblocks and oppositely charged surfactant micelles or 7 nm cerium oxide nanoparticles. Light scattering and reflectometry measurements revealed that the hybrid nanoparticle aggregates were more stable through ...
