Nucleation and crystal growth in supersaturated solutions of a model drug.
The crystallization process in aqueous solutions of the drug bicalutamide and the effect of the polymer polyvinylpyrrolidone (PVP) have been studied. Results showed that PVP decreased theExpand
Analysis of gun phenotype in barley magnesium chelatase and Mg-protoporphyrin IX monomethyl ester cyclase mutants.
The ability of barley (Hordeum vulgare L.) chlorophyll biosynthetic mutants to regulate the expression of Lhc genes was analyzed by a microarray approach. The Lhc genes are located in the nucleus andExpand
A record nine different phases (four cubic, two hexagonal, and one lamellar lyotropic liquid crystalline and two micellar solutions) in a ternary isothermal system of an amphiphilic block copolymer
We report on a ternary isothermal system consisting of a poly(ethylene oxide)/poly(propylene oxide) (PEO/PPO) amphiphilic block copolymer, “water”, and “oil” (where "water" and "oil" are selective solvents for the different blocks), which exhibits the richest structural polymorphism ever observed in mixtures containing amphiphiles.

Dilute lamellar and L3 phases in the binary water–C12E5 system
The binary phase diagram of water–C12E5 has been studied with emphasis on the L3 and dilute lamellar phases, which were found to swell to approximately 99.5 and 98.8 wt % of water, respectively, muchExpand
Change of the structure of microemulsions with the hydrophile-lipophile balance of nonionic surfactant as revealed by NMR self-diffusion studies
Etudes illustrees par l'exemple de la microemulsion formee par l'eau, le tetradecane et l'agent de surface non ionique C 12 H 25 (OCH 2 CH 2 ) 5 OH
Self-assembly of amphiphilic block copolymers: The (EO)13(PO)30(EO)13-water-p-xylene system
The self-assembly of a poly(ethylene oxide)-block-poly(propylene oxide)-block-poly(ethylene oxide) copolymer (Pluronic L64, (EO) 13 (PO) 30 (EO) 13 ) in the presence of water and p-xylene wasExpand
Amorphous drug nanosuspensions. 2. Experimental determination of bulk monomer concentrations.
A simple turbidimetric method was developed to measure the bulk concentration of drug in nanosuspensions. The bulk concentrations measured were in the range from 1 microM to 1 mM. The accuracy of theExpand
We investigated the effect of water-soluble alcohols (glycerol, propylene glycol, and 1-propanol) on the surfactant aggregation and its structure by phase study, surface tension measurement,Expand
Phase Diagram and Phase Properties of the System Lecithin−Water−Cyclohexane
The isothermal quasi-ternary-phase diagram of the lecithin−cyclohexane−water system was determined at 25 °C using a combination of polarizing microscopy, small-angle X-ray diffraction, and NMRExpand
Preparation of calcium alginate nanoparticles using water-in-oil (W/O) nanoemulsions.
A procedure for the preparation of calcium alginate nanoparticles in the aqueous phase of water-in-oil (W/O) nanoemulsions was developed. The emulsions were produced from mixtures of the nonionicExpand
