Optimization of the operative conditions for heteropolyacids synthesis through ion exchange

In the “big picture” perspective of the recent years that we have described in Brazil, Spain, Portugal and Puerto Rico there are some similarities and important differences,

In order to confirm that the aggregates formed in toluene are compatible with the size expected for a dimer model (about 5 nm in diameter), DOSY NMR experiments were carried out in

The following figures show the evolution along more than half a solar cycle of the AR faculae and network contrast dependence on both µ and the measured magnetic signal, B/µ,

Recent observations of the bulge display a gradient of the mean metallicity and of [Ƚ/Fe] with distance from galactic plane.. Bulge regions away from the plane are less

(hundreds of kHz). Resolution problems are directly related to the resulting accuracy of the computation, as it was seen in [18], so 32-bit floating point may not be appropriate

Even though the 1920s offered new employment opportunities in industries previously closed to women, often the women who took these jobs found themselves exploited.. No matter

Based on the required functionalities and evolving the Media Independent Layer proposed in IEEE 802.21, in section 3., we propose a new architecture for a Media Independent
