From Waste to Value: Conversion of Calcium Sulfate to Vaterite via Carbon Capture and Storage

Advanced Functional Materials, Volume 36, Issue 34, 27 April 2026.
This study introduces a new concept for carbon management that relies on the carbonation of industrial gypsum waste and yields phase‐pure vaterite at ambient conditions without any additives. The obtained vaterite is further shown to be a reactive material that develops compressive strength in aqueous suspensions like conventional cements.

Insights Into the Mechanisms Controlling the Residual Strength of Bio‐cemented Sands

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 6, Page 2711-2726, 25 April 2026.
ABSTRACT Microbially induced carbonate precipitation (MICP) is an emerging technique for enhancing the mechanical properties of granular soils. Although several experimental studies have reported increased shear strength in MICP‐treated soils at both peak and residual states, other findings have shown reductions in residual strength compared to ...

Dark cytotoxicity of submicrometer vaterite particles loaded with photosensitizer Fotoditazin and the vaterite-based core – shells structures

Reviews on Clinical Pharmacology and Drug Therapy, 2021
Photodynamic therapy (PDT) is based on the use of photosensitizers together with a light at the wavelength corresponding to its absorption maximum. Photosensitizers are able to generate reactive oxygen species under the visible or infrared light irradiation.

Harvesting the Spin–Orbit Interaction of Light to Generate Helicity‐Dependent Complex Rotational Motion in Optically Trapped Mesoscopic Matter

Nanophotonics, Volume 15, Issue 5, 16 March 2026.
Spin–orbit interaction (SOI) of light is exploited to generate helicity‐dependent complex rotational and revolution dynamics in optical tweezers. At the trap center, particle rotation is governed by the direct helicity that follows the input polarization.

Bio‐Inspired Nanoarchitected LiFePO4 Cathodes

Advanced Functional Materials, Volume 36, Issue 23, 19 March 2026.
Lithium iron phosphate (LFP) is synthesized using a bio‐inspired method, using acidic macromolecules similar to those found in many calcareous mineralized organisms to modulate the morphology and crystal growth of LFP‐carbon composite particles. The observations from this process indicate a non‐classical crystallization process, which subsequently ...

Nanostructure and crystallography of aberrant columnar vaterite in Corbicula fluminea (Mollusca)

Both the crystallographic and nanostructural organisation of aberrant columnar vaterite occurring in C. fluminea were characterised in detail for the first time using electron microscopic and x-ray powder diffraction techniques.

Effects of temperature, pH and calcium-to-carbonate ratio on the calcium carbonate polymorphs

Discover Civil Engineering
The precipitation of calcium carbonate (CaCO3) polymorphs (calcite, vaterite, and aragonite) plays a crucial role in tailoring the physicochemical properties of construction materials during mineral carbonation.

A Review of the Structures of Vaterite: The Impossible, the Possible, and the Likely [PDF]

Crystal Growth & Design, 2017
The importance of the metastable vaterite form of CaCO is increasingly appreciated as an intermediate between amorphous calcium carbonate and more stable crystalline polymorphs in biogenic calcification pathways. Thus, there is a need to be able to identify nanocrystals of vaterite unambiguously, despite uncertainties about its exact crystal structure.

Integrating Direct Air Capture Technology and Plasma Based Calcination for Sustainable Syngas and Concrete – An Experimental Investigation

Advanced Materials Interfaces, Volume 13, Issue 6, 16 March 2026.
This study presents an experimental Proof‐of‐Concept of an electrified CO2${\rm CO}_2$ loop that combines DAC and GA‐plasma conversion. Atmospheric CO2${\rm CO}_2$ is captured and solidified as CaCO3${\rm CaCO}_3$, followed by plasma‐based calcination to regenerate CaO and with the possibility to split CO2${\rm CO}_2$ into CO for syngas synthesis.

Facile synthesis of vaterite fine powder CaCO3 from padalarang natural limestone with pH modifying via fine-bubble carbonation

Materials Research Express
Natural limestone, known for its high calcium carbonate (CaCO _3 ) content (∼95%) and safety in health applications, is widely used in science and industry. It exists in three forms: calcite, vaterite, and aragonite.
