A graphical representation of the equilibrium relationships between phases (such as vapor-liquid, liquid-solid) of a chemical compound, mixture of compounds, or solution. (thermodynamics) A graph showing the pressures at which phase transitions between different states of a pure compound occur, as ...
pH-sensitive polymeric physical-mixture for possible site-specific delivery of ibuprofen. Delivery of drugs to the large bowel has been extensively investigated during the last decade. The aim of this work was to study polymethacrylic acid-co-me... B Luppi,T Cerchiara,F Bigucci,... - 《E...
Upon entry of food, they relax briefly, then begin to contract. Periodic contractions churn and knead food into a semifluid mixture called chyme; rhythmical pumping (peristaltic) waves move food toward the pylorus and small intestine. Peristaltic contractions persist after the stomach empties and, ...
Phase diagram is a graphic representation of the equilibrium relationships between phases (such as vapour-liquid, liquid-solid) of a chemical compound, mixture of compounds, or solution. The figure shows a typical phase diagram of an element or a simple compound. The stability of solid, liquid ...

70 mg of each of the Ln1−xSrxCoO3−δ samples was carried out using a SETARAM TAG24 Simultaneous Thermogravimetric and Differential Thermal Analyser. The samples were reduced under a mixture of 3.5% hydrogen in nitrogen over a temperature range of 25–950°C at a heating rate of 5°C...

The samples were prepared by the coprecipitation of FeII and FeIII species in different kinds of aqueous solutions. This simple method, which consists to add a basic solution to a mixture that contains FeII and FeIII dissolved species, is well known for the synthesis of the other members of...
X-ray powder diffraction studies confirm that the eutectics are not simple mechanical mixture of the components under investigation. The spectroscopic investigations (IR and NMR) suggest the occurrence of hydrogen bonding between the components forming the molecular complex. The dielectric measurements, ...
