Aluminium in an ocean general circulation model compared with the West Atlantic Geotraces cruises [PDF]
J.Mar.Syst. 126 (2013) 3-23, 2012 A model of aluminium has been developed and implemented in an Ocean General Circulation Model (NEMO-PISCES). In the model, aluminium enters the ocean by means of dust deposition. The internal oceanic processes are described by advection, mixing and reversible scavenging.

Adsorption of benzene, phenol, propane and carbonic acid molecules on oxidized Al(111) and alpha-Al2O3(0001) surfaces: A first-principles study [PDF]
J. Phys.: Condens. Matter 21 (2009) 225001, 2009 We present the results of ab initio calculations describing the adsorption of certain small organic molecules on clean and oxidized Al(111) surfaces as well as on the alpha-Al2O3(0001) surface. Our results show that adsorption of benzene on the clean and oxidized Al(111) surfaces is generally weak, the adsorption energy being at most around -0.5 eV per
