Aluminium speciation was studied in aqueous extracts of forest soils in the vicinity of an aluminium smelter in Galicia, NW Spain. Two soil depths (0-10 and 10-20 cm) were sampled within a 3.5 km radius around the factory. Forest soils samples far away from the factory were used as a control. Aqueous extracts (1:10 soil:water ratio) were analyzed for pH,(More)
In the last years the Global Positioning System has become a worthwhile tool supporting wide range of elds in the Earth Sciences. One of its recent applications to study the sea is the using of GPS buoys for the calibration of satellite altimeters as well as for the validation of the geophysical data records (GDR) derived from the altimeter measurements. In(More)
Fluorine is a phytotoxic element that can reach the soil from various industrial activities. Fluorine sorption by soil is crucial to protect water and food chain from fluorine pollution. In Galicia (NW Spain), various activities emit fluorine into the atmosphere, mainly ceramic industries and an aluminium smelter. This study, aiming to investigate fluorine(More)

This paper deals with the possibility of forming short and relatively strong carbon-helium bonds in small typical organic molecules through substitution of one or several H atoms by He(+). A structural and energetics study (based on high-level calculations) of this unusual bonding, as well as a topological characterization of the resulting cations, is(More)
The synthesis of the commercially available aluminum fumarate sample A520 has been optimized and its structure analyzed through a combination of powder diffraction, solid-state NMR spectroscopy, molecular simulation, IR spectroscopy, and thermal analysis. A520 is an analogue of the MIL-53(Al)-BDC solid, but with a more rigid behavior. The differences(More)
