• Olivine and feldspar exhibit similarities regarding their ash layer formation. Formation of layers is more pronounced on convex areas bed particles. A Mn Fe causes the particles to an oxygen carrying ability. Alkali alkaline earth metals are present surface alkali-feldspar were utilized in separate campaigns indirect dual fluidized gasification campaign with woody biomass as fuel. After three...

Alkaline earth elements and alkali metals (Mg, Ca, Na and K) play an important role in the geochemical evolution of saline lakes as the final brine type is defined by the abundance of these elements. The role of major ions in brine evolution has been studied in great detail, but little has been done to investigate the behaviour of minor alkali elements in these systems despite their similar che...

The ability of dead cells of endophytic Drechslera hawaiiensis of Morus alba L. grown in heavy metals habitats for bioremoval of cadmium (Cd2+), copper (Cu2+), and lead (Pb2+) in aqueous solution was evaluated under different conditions. Whereas the highest extent of Cd2+ and Cu2+ removal and uptake occurred at pH 8 as well as Pb2+ occurred at neutral pH (6-7) after equilibrium time 10 min. Ini...

Strategies to produce an ultracold sample of carbon atoms are explored and assessed with the help of quantum chemistry. After a brief discussion of the experimental difficulties using conventional methods, two strategies are investigated. The first attempts to exploit charge exchange reactions between ultracold metal atoms and sympathetically cooled C(+) ions. Ab initio calculations including e...

The catalytic pyrolysis of beech wood and corncob was experimentally investigated considering six additives containing alkali alkaline earth metals (Na2CO3, NaOH, NaCl, KCl, CaCl2 MgCl2). Thermogravimetric analyses (TGA) were carried out with raw feedstocks samples impregnated different concentrations catalysts. In a bid to better interpret observed trends, measured data analyzed using an integ...
