Fe3O4 encapsulated PEG form iron sand at wari ino beach has been successfully synthesized by co-precipitation method. The average particle size  of the nanoparticle 11,3 nm was determined by scherrer formula. Fe3O4 modification PEG 4000 was successfu... see more

Telah dilakukan penelitian dengan judul "Karakterisasi Fisikokimia Sistem Biner Siprofloksasin HCl – PEG 4000". Penelitian ini bertujuan untuk mengkarakterisasi siprofloksasin HCl yang dikembangkan menjadi 9 formula, dengan perbandingan antara siprofloksa... see more

In the present work investigations were performed concerned with the determination of the optimal ratio of vinpocetine and polyethylene glycol within a solid dispersion (1:2 or 1:5) according to the simulation results in the framework of molecular dynamic... see more

Liquid-liquid extraction using aqueous two-phase systems (ATPSs) is a promising technique for the purification of biomolecules of industrial and laboratory interest. This work presents a study of the phase diagrams for different poly(ethylene glycol) (PEG... see more

Metformin is a hydrophilic hypoglycemic agent with permeability and short half-life problems which leads to its low bioavailability. Solid dispersion is one of the unique approaches, to improve bioavailability profiles of drugs. The aim of this study was ... see more

Several technical factors related to penicillin G intramuscular injection can affect its bioavailability and hence reduce the efficacy of rheumatic fever prevention program. When small amount of diluent is used, the powder is not completely dissolved and ... see more

Magnesium Ferrite Magnesium (MgFe2O4) magnetic nanoparticles have been successfully carried out by varying the concentrations of PEG-4000 and silica as encapsulation materials using coprecipitation methods. The X-ray Diffraction (XRD) analysis showed that... see more

A sol-gel method was used to synthesise Sm2Ti2O7 photocatalysts. It was found that crystalline formation of pyrochlore phase Sm2Ti2O7 is promoted by addition of the PEG4000 template. Reduced particles aggregation was observed in the porous Sm2Ti2O7. The a... see more

Aqueous two-phase system (ATPS) is an efficient, cost effective, fast, simple and ecofriendly method for the recovery of biomolecules. In the present study, an ATPS composed of polyethylene glycol and ammonium sulphate (NH4)2SO4 was used for the partial p... see more
