Tuning the Magnetization of Manganese (II) Carbonate by Intracrystalline Amino Acids
Arad Lang, Iryna Polishchuk, Giorgia Confalonieri +5
Incorporation of organic molecules into the lattice of inorganic crystalline hosts is a common phenomenon in biomineralization, and has been shown to alter various properties of th…
Pore and Ligament Size Control, Thermal Stability and Mechanical Properties of Nanoporous Single Crystals of Gold
Maria Koifman Khristosov, Shiri Dishon, Imrit Noi +2
Nanoporous gold is widely used in research and nanotechnology because of its diverse properties, including high surface area and catalytic activity. The ligament size is usually co…
Density of Nanometrically Thin Amorphous Films Varies by Thickness
Yael Etinger-Geller, Alex Katsman, Boaz Pokroy
Organisms in nature can alter the short-range order of an amorphous precursor phase, thereby controlling the resulting crystalline structure. This phenomenon inspired an investigat…
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…
A gold complex single crystal comprised of nanoporosity and curved surfaces
Maria Koifman Khristosov, Leonid Bloch, Manfred Burghammer +4
Complex hierarchical shapes are widely known in biogenic single crystals, but growing of intricate synthetic metal single crystals is still a challenge. Here we report on a simple…
Association Between Gold Grain Orientation And Its Periodic Steps Formed At The Gold/Substrate Interface
Linfeng Chen, Maria Koifman Khristosov, Cecile Saguy +2
Nanoscale step structures have attracted recent interest owing to their importance in both fundamental and applied research, for example in adsorption, in catalysis, and in directi…
Bio-inspired Band Gap Engineering of Zinc Oxide by Intracrystalline Incorporation of Amino Acids
Anastasia Brif, Guy Ankonina, Christina Drathen +1
During a bioInspired crystallization process, incorporation of amino acids into the crystal structure of ZnO induces lattice strain that leads to linear bandgap shifts.
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…
Residual strain and stress in biocrystals
E. Seknazi, B. Pokroy
The development of residual strains within a material is a valuable engineering technique for increasing the material's strength and toughness. Residual strains occur naturally in…
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…
Thickness Dependence of the Physical Properties of Atomic-Layer Deposited Al2O3
Yael Etinger-Geller, Ekaterina Zoubenko, Maria Baskin +2
Inspired by nature, we investigate the short-range order effect on the physical properties of amorphous materials. Amorphous Al2O3 thin films exhibit a higher proportion of their 4…
Intracrystalline inclusions within single crystalline hosts: from biomineralization to bio-inspired crystal growth
Eva Weber, Boaz Pokroy
Many crystals in nature exhibit fascinating mechanical, optical, magnetic and other characteristics. One of the reasons for this phenomenon has to do with the presence of specific…
