Molecular environmental scientists employ a combination of micro and macroscale techniques to elucidate the reaction processes taking place at surface and subsurface environments.

 

Themes generally addressed by molecular environmental scientists involve the role of microbes in mineral transformations, cycling of plant nutrients and heavy metals and the impacts of anthropogenic activites in the environment.

 

Advances in the use of synchrotron radiaton techniques have enabled researchers to elucidate environmental interfacial reactions that were once only glimpsed by theory, which now can otherwise be directly observed. 

 

This is because synchrotron radiation gives access to X-ray energies ranging from ~ 10 eV up to 100 keV, which is the typical energy range where wavelengths are short enough, comparable to interatomic lengths, thus enabling one to obtain detailed local atomic structural information of stuff.

 

Molecular Environmental Sciences (MES) research at the LNLS has rather relied on synchrotron-based X-rays absorption spectroscopy (XAS), X-rays diffraction (XRD), X-rays fluorescence (XRF) and X-rays microtomography to study interfacial reactions at their very fundamental level - the molecular/atomic level.

Brazilian Synchrotron Light Laboratory

The LNLS (Brazilian Synchrotron Light Laboratory, in Portuguese) is a second generation radiation source that was designed in 1983 and became operational 14 years later, in 1997. Located in Campinas, São Paulo state (Southeast of Brazil), it is home to more than twenty reserchers involved in several fields of research.

 

Whereas Brazil was one of the first developing countries to build a synchrotron light source, the LNLS was the first synchrotron facility in the southern hemisphere.

 

The LNLS receives annually approximately 1000 scientists representing more than 50 home and international institutions, to conduct research at LNLS beamlines in the fields of biology, chemistry, environmental sciences, geology, materials science, medicine, metallurgy and physics

 

Since the beginning of 2009, a new 4th generation synchrotron radiation source, Sirius, has been designed, and will deliver brilliance comparable to those in planning or construction phases around the world.
