Synthesis of calcium carbonate in trace water environments
Giulia Magnabosco, Iryna Polishchuk, Boaz Pokroy +3
Calcium carbonate (CaCO3) was synthesized from diverse water-free alcohol solutions, resulting in the formation of vaterite and calcite precipitates, or stable particle supensions,…
Hybrid gold single crystals incorporating amino acids
Linfeng Chen, Iryna Polishchuk, Eva Weber +2
Here we report on the formation of hybrid organic-metal composites via the incorporation of selected amino acids into the crystal lattice of single crystals of gold. We used electr…
Additives Influence the Phase Behavior of Calcium Car-bonate Solution by a Cooperative Ion-association Process
Zhaoyong Zou, Iryna Polishchuk, Luca Bertinetti +4
Amorphous calcium carbonate (ACC) has been widely found in biomineralization, both as a transient precursor and a stable phase, but how organisms accurately control its formation a…
Insights on the interaction of calcein with calcium carbonate and its implications in biomineralization studies
Giulia Magnabosco, Iryna Polishchuk, Jonathan Erez +3
The effects of calcein, a marker commonly used to assess mineral growth in calcifying organism, on calcite and aragonite structure have been investigated. Calcein is entrapped with…
Strong Quantum Confinement Effects and Chiral Excitons in Bio-Inspired ZnO-Amino Acid Co-Crystals
Madathumpady Abubaker Habeeb Muhammed, Marlene Lamers, Verena Baumann +10
Elucidating the underlying principles behind band gap engineering is paramount for the successful implementation of semiconductors in photonic and optoelectronic devices. Recently…
Effect of surface chemistry on incorporation of nanoparticles within calcite single crystals
Giulia Magnabosco, Iryna Polishchuk, Francesco Palomba +5
Inclusion of additives into calcite crystals allows one to embed non-native proprieties into the inorganic matrix and obtain new functional materials. Up to now, few parameters hav…
Photocatalytic activity of exfoliated graphite-TiO nanocomposites
Gloria Guidetti, Eva A. A. Pogna, Lucia Lombardi +16
We investigate the photocatalytic performance of nanocomposites prepared in a one-step process by liquid-phase exfoliation of graphite in the presence of TiO nanoparticles (NPs…
Formation and Stability of Ordered and Disordered Ba-substituted Calcite Phases
E. Seknazi, D. Levy, I. Polishchuk +2
Calcite has the ability to host large amounts of intracrystalline inclusions, a phenomenon that is known to be the case in biominerals and has been demonstrated in bio-inspired syn…
