It was found that sarcosine can maintain a higher pKₐ than the other amino acids studied at high temperatures. We also found that the CO₂ solubilities and overall mass-transfer coefficients of 5 m' sarcosinate (moles of sarcosine per kilogram of solution) at 333-353 K are higher than those of 30% MEA at 313-353 K. These results show that some possible benefits can be produced from the use of sarcosine as a fast solvent for CO₂ absorption at high temperatures. However, the pronotation reaction of sarcosine is the least exothermic among those of all amino acids studied. This could lead to a high regeneration energy consumption in the sarcosinate-based CO2 capture process.]]> Sat 24 Mar 2018 07:49:59 AEDT ]]> Thermodynamic analysis of a novel two-step high temperature thermo-electrochemical water splitting cycle https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52920 500 °C to conduct both reactions in STCH, could operate at lower temperatures and ΔT = 0 °C. Reaction conditions were evaluated showing that it may also be possible to increase the oxygen partial pressure while still achieving high fuel conversion, which would not be possible operating under the conventional SOE and STCH conditions.]]> Mon 29 Jan 2024 18:27:42 AEDT ]]> Boron nitride nanotube nucleation during Ni-catalyzed boron oxide chemical vapor deposition https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:36649 2O production being assumed to accompany the formation of BN during BOCVD, we do not observe Ni-catalyzed evolution of H2O, although significant amounts of H2 is evident. At low oxygen chemical potentials, defect-free BN ring networks are produced following the oligomerization of BN chain structures and the Ni-catalyzed cleavage of homoelemental B-B and N-N bonds. The BNNT tip structures align perpendicular to the surface via the direct fusion of adjacent BN ring networks via a mechanism that is a stark departure from that observed for carbon nanotube nucleation.]]> Mon 22 Jun 2020 14:38:29 AEST ]]>
