Directed precipitation of anhydrous magnesite for improved performance of mineral carbonation of CO2
Atashin, Sanam; Varin, Robert A.; Wen, John Z. (Elsevier, 2017-08-01)This paper studies the indirect aqueous carbon sequestration via Mg(OH)2 using directed precipitation technique. This technique produces anhydrous MgCO3 (magnesite), the most desirable carbonated phase for sequestration. ... -
The Effects of Additives on the Dehydrogenation of Amorphous Manganese Borohydride and Its Crystalline Form after Solvent Filtration/Extraction
Varin, Robert A.; Mattar, Deepak; Polanski, Marek; Bidabadi, Amirreza; Stobinski, Leszek (Multidisciplinary Digital Publishing Institute, 2017-10-30)A non-stoichiometric, amorphous a-Mn(BH4)(2x) hydride, accompanied by a NaCl-type salt, was mechanochemically synthesized from the additive-free mixture of (2NaBH4 + MnCl2), as well as from the mixtures containing the ... -

The effects of filamentary Ni, graphene and lithium amide (LiNH2) additives on the dehydrogenation behavior of mechano-chemically synthesized crystalline manganese borohydride (Mn(BH4)2) and its solvent filtration/extraction
Varin, Robert A.; Bidabadi, Amirreza Shirani; Polanski, Marek; Biglari, Mazda; Stobinski, Leszek (Elsevier, 2018-04-01)Dehydrogenation properties of mechano-chemically synthesized crystalline Mn(BH4)2 hydride without and with ultrafine filamentary carbonyl nickel (Ni), graphene and LiNH2 were investigated. It is reported for the first time ...
