In the present study, the bark ethanol extract of Maytenus guyanensis Klotzch (Celastraceae) was investigated for total phenol content, free radical scavenging (DPPH,ABTS, superoxide anion radical and singlet oxygen), an...

Densities of aqueous solutions of sodium naproxen have been measured as functions of concentration (from 0.0250 to 0.5000 mol kg-1) and temperature (from 278.15 to 313.15 K). The apparent molar volumes, partial molar vol...

Ethylhexyl triazone (EHT) is a sunscreen agent widely used in the formulation of skin care products, whose physicochemical properties have not been thoroughly studied. In this work the Extended Hildebrand Solubility Ap...

Images compression is a widely studied topic. Conventional situations offer variable compression ratios depending on the image in question and, in general, do not yield good results for images that are rich in tones. Thi...

Osmotic and activity coefficients were measured for aqueous solutions of Lidocaine-HCl and Procaine-HCl using the isopiestic method at 298.15 K. The results were fitted to the Pitzer equation and the parameters were calc...

The binary solvent system ethanol + ethyl acetate is widely used in the pharmaceutical sciences as a versatile model for studying the solubility of drugs. In this context, the excess molar volumes and the partial molar v...
