The Crystallization Process of Vaterite Microdisc Mesocrystals via Proto-Vaterite Amorphous Calcium Carbonate Characterized by Cryo-X-ray Absorption Spectroscopy

open access: yesCrystals, 2020
Investigation on the formation mechanism of crystals via amorphous precursors has attracted a lot of interests in the last years. The formation mechanism of thermodynamically meta-stable vaterite in pure alcohols in the absence of any additive is less ...

Optothermal Needle‐Free Injection of Vaterite Nanocapsules

open access: yesAdvanced Science, 2023
AbstractThe propulsion and acceleration of nanoparticles with light have both fundamental and applied significance across many disciplines. Needle‐free injection of biomedical nano cargoes into living tissues is among the examples. Here a new physical mechanism of laser‐induced particle acceleration is explored, based on abnormal optothermal expansion ...

Structure and phase analysis of calcium carbonate powder prepared by a simple solution method

open access: yesHeliyon, 2021
This paper focused on the analysis of the crystal structure and phase transformation of CaCO3 synthesized by simple solution method from 0.5 M Ca(NO3)2 precursor and 0.5 M Na2CO3 precipitant at ambient temperature (300 K).

Golden Vaterite as a Mesoscopic Metamaterial for Biophotonic Applications [PDF]

open access: yesAdvanced Materials, 2021
AbstractMesoscopic photonic systems with tailored optical responses have great potential to open new frontiers in implantable biomedical devices. However, biocompatibility is typically a problem, as engineering of optical properties often calls for using toxic compounds and chemicals, unsuitable for in vivo applications.

Rearing in strontium-enriched water induces vaterite otoliths in the Japanese rice fish, Oryzias latipes

open access: yesRoyal Society Open Science, 2023
Sagittal otoliths, typically composed of aragonite, are frequently laid down rather as vaterite during growth in hatchery-reared fish populations. Sagittal vateritization is believed to impair individual hearing/balancing abilities, but the causal ...

Monodisperse and Nanometric-Sized Calcium Carbonate Particles Synthesis Optimization

open access: yesNanomaterials, 2022
Calcium carbonate (CaCO3) particles represent an appealing choice as a drug delivery system due to their biocompatibility, biodegradability, simplicity and cost-effectiveness of manufacturing, and stimulus-responsiveness.

Vaterite in Lake Water [PDF]

open access: yesNature Physical Science, 1971
IN a recent communication, Rowlands and Webster1 pointed out that the occurrence of vaterite in nature is extremely rare compared with other forms of calcium carbonate, for example, calcite and aragonite. I wish to report some additional relevant information.

Vaterite Stability in the Presence of Chromate [PDF]

open access: yesSpectroscopy Letters, 2011
Vaterite aggregates grown in Cr(VI)-bearing silica gel were studied by combining scanning electron microscopy and Raman spectroscopy. All the vaterite samples were spherical aggregates consisting of lens-shaped individuals, and their morphology was distinctive for vaterite.
