Aqueous Potassium Bicarbonate/Carbonate Ionic Equilibria at Elevated Pressures and Temperatures

, 2016
Aqueous bicarbonate/carbonate ionic equilibria play an important role in determining the practicality of various aqueous-alkaline fuel cells and the hot carbonate process for removing carbon dioxide from synthesis gas streams.

New insight into the stability of CaCO3 surfaces and nanoparticles via molecular simulation [PDF]

, 2014
Using updated and improved atomistic models for the polymorphs of calcium carbonate and their constituent ions in solution, we revisit the question of surface energetics and nanoparticle stability.

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Temperature oscillation modulated self-assembly of periodic concentric layered magnesium carbonate microparticles. [PDF]

PLoS ONE, 2014
Intriguing patterns of periodic, concentric, layered, mineral microstructure are present in nature and organisms, yet they have elusive geneses. We hypothesize temperature oscillation can be an independent factor that causes the self-assembly of such ...

Experimental investigation of calcium carbonate mineralogy in past and future oceans [PDF]

, 2011
Inorganic marine calcium carbonate formation and mineralogy varies significantly concurrent with the solution composition. During the Phanerozoic, due to oscillations in the seawater composition, this resulted in the formation of either dominantly ...

Electrolyte‐Induced Cu+ Preservation Results in a Selectivity Switch of Electrocatalytic CO2 Reduction at a Copper‐Organic Framework as Electrocatalyst

Advanced Functional Materials, EarlyView.
The active role of KCl as a neutral electrolyte enables switching the selectivity on a Cu organic framework from C1 to C2+ products during electrocatalytic CO2 reduction. ABSTRACT We introduce a copper‐nicotinate (Cu‐NA) framework as a halogenide‐stabilized Cu+/Cu0 pre‐catalyst for electrocatalytic CO2 reduction with high C2+ selectivity in a “neutral”

A bicarbonate-rich liquid condensed phase in non-saturated solutions in the absence of divalent cations

Frontiers in Bioengineering and Biotechnology
Bicarbonate (HCO3−) and sodium (Na+)-containing solutions contain droplets of a separate, bicarbonate-rich liquid condensed phase (LCP) that have higher concentrations of HCO3− relative to the bulk solution in which they reside.

Laboratory Models of Microbial Biosignatures in Carbonate Rocks [PDF]

, 2005
Enigmatically shaped laminated carbonate rocks called stromatolites dominated shallow marine environments for the first 80% of Earth’s history, and are potentially the oldest macrofossils.
