The chapter provides a treatment of the interaction between acidic or basic polyelctrolytes (PE) and ionizable organic molecules (selected model drugs) in aqueous environments, in terms of acid-base reactions. The ...

In the Argentina Puna region there are several metal sulfide mines that ceased their activity twenty years ago without a proper closure plan. The exposure of the waste rocks and tailing impoundments to weathering led to ...

The sources and dynamics of arsenic in fresh volcanic ashes collected during the eruptions of Hudson (1991) and Puyehue (2011) volcanos, have been studied. The chemical and mineralogical compositions of both volcanic ashes ...

Carbon-coated magnetite nanoparticles (NPs) were synthetized by the mechanochemical method with hematite as precursor and amorphous carbon as inorganic reductor. After 18 hours of milling in an inert atmosphere, a nanocomposite ...

Monomolecular films of surfactants at the air-water interface are easy to prepare and to handle, and enable a broad variety of techniques to be used. As in other model-systems mimicking membranes, two-phases are observed ...

The caudate-putamen (CPu) of the striatum is one of the main entrances to the basal ganglia. The CPu is fundamentally a dopaminergic area receiving dopamine innervation from the substantia nigra, ventral tegmental area, ...

Arsenic in natural water is a worldwide concern due to chronic health effects in people exposed through the drinking water. The aim was to evaluate the distribution of As(III) and As(V), through ASV, in an Argentine area ...

It has been described that development and persistent expression of addictive behaviors occur through the usurpation of natural learning and memory mechanisms within the limbic system. Hippocampus (HP) and medial prefrontal ...

Los laboratorios deben demostrar que los métodos analíticos que utilizan proveen resultados fiables y adecuados para la finalidad y el propósito perseguidos, ya que muchas de las decisiones que se toman están basadas en ...
