Summary: This study investigates the biomimetic potential of using amorphous CaCO3 (ACC) to mimic crustacean exoskeletons and optimize their physical and chemical properties. The researchers prepared monodisperse ACC microspheres with high sphericity and hardness using the gas diffusion method in the presence of Mg2+. The stability of ACC was found to be affected by environmental conditions, but the microspheres showed high stability under ambient conditions. This research provides guidance for the preparation of ACC biomimetic composites and enhances the understanding of biomineralization mechanisms.

Summary: This study aimed to develop an approach to load silver nanoparticles (AgNPs) into mesoporous calcium carbonate vaterite crystals (CaCO3 vaterite) to improve their stability and controlled release. Different capping agents were used to enhance the colloidal stability of AgNPs, and the loading and release mechanisms of AgNPs in CaCO3 crystals were investigated. The results demonstrated that certain capping agents effectively maintained the colloidal stability of AgNPs during co-precipitation with CaCO3 crystals. The developed approach has potential applications in stabilizing, protecting, storing, and releasing AgNPs for antimicrobial use. Rating: 7/10

Summary: Selenium can become toxic due to its bioaccumulation potential, but can be immobilized by the mineral calcite. The incorporation of Se into calcite can be influenced by the presence of foreign ions in aqueous solution, affecting the precipitation of different phases such as vaterite and aragonite. The aging process of calcium carbonates precipitated from solutions highly supersaturated with respect to CaCO3 and slightly supersaturated with respect to CaSeO3 & BULL;H2O showed that vaterite hosting Se had low crystallinity and the transformation to calcite was inhibited.

Summary: The study investigates the impact of various chelating agents on the crystallization, polymorphism, and morphology of CaCO3 in the presence of barium at 100 degrees C. Different additives were found to stabilize different polymorphs of CaCO3, leading to enhanced scale inhibition efficiency. The mechanism of polymorph stabilization by the additives and the effect of blending different additives were discussed for better understanding of the scale inhibition process.

Summary: Vaterite with submicrometer particles was successfully synthesized by adding sucrose at certain amounts to the aqueous solutions of (NH4)2CO3 and CaCl2 precursors. The addition of sucrose resulted in a reduction in particle size and an increase in the percentage of vaterite phase. The round shape of the vaterite particles was observed using SEM and TEM techniques, and their stability in NR latex was attributed to the negative charges on the surface of NR particles.

Summary: This study aims to achieve the high-value application of calcium during seawater decalcification. Aragonite or vaterite with a high purity exceeding 99% was successfully synthesized using synthetic seawater as a calcium source and Na2CO3/NaHCO3 solution as the carbonate supplier. The effects of coexisting ions in synthetic seawater on crystal polymorph and crystallization kinetics were systematically investigated, and it was found that the presence of Mg2+, K+ or SO42- favored the precipitation of aragonite while Mg-free synthetic seawater favored the formation of vaterite. Additionally, hydrophobic spherical vaterite particles were prepared by in-situ surface modification using alka-nolamide 6502 as a surfactant, demonstrating a promising approach to enhance the utilization of calcium during the seawater decalcification process.

Summary: Three anhydrous calcium carbonate polymorphs (calcite, aragonite, and vaterite) were synthesized and characterized in this study. The effects of these polymorphs on cement pastes, including compressive strength, hydration kinetics, and phase compositions, were investigated. The results showed that aragonite and vaterite remained stable in the cement systems even after a prolonged age, which had implications for their use in cement systems depending on the intended applications.

Summary: In this research, all three forms of calcium carbonate (calcite, aragonite, and vaterite) were synthesized and their effects on cement rheology were studied. It was found that aragonite increased the yield stress and storage modulus of cement pastes, while calcite and vaterite did not. The mechanisms underlying these changes were discussed, including geometric features, hydration kinetics, and surface charge.

Summary: Calcium carbonate (CaCO3) particles are a promising choice for drug delivery systems due to their biocompatibility, biodegradability, simplicity, cost-effectiveness, and stimulus-responsiveness. This study investigated the synthesis parameters that affect the particle size, and found that salt concentration and temperature had a significant impact, allowing the preparation of well-dispersed spherical nanoparticles below 200 nm. The successful encapsulation of the anti-tumor agent resveratrol into CaCO3 nanoparticles, without affecting their overall size and morphology, was achieved under optimized synthesis conditions.

Summary: Tailor-made micro- and nanocarriers, combining cyclodextrin and calcium carbonate, were developed for loading hydrophobic drugs. The particle size of the resulting cyclodextrin-CaCO3 particles can be controlled by adjusting the concentration of PVSA or gly and the mixing time. These particles show high stability and biocompatibility, and exhibit selective release in acidic media.

Summary: Preceramic polymer resins are ideal for 3D printing ceramic components, and the outcomes of the process strongly depend on parameters like catalyst concentration and cross-linking duration, affecting ceramic density and yield. Thermal analysis and FTIR are used to quantify these relationships and determine the best parameters for 3D printing PDC components, providing guidelines for future additive manufacturing of PDCs.

Summary: This study demonstrates the use of sodium alginate to stabilize sodium sulfate decahydrate for thermal energy storage, resulting in high phase change enthalpy and extended cycling stability. The stabilization effect is attributed to the ionic and hydrogen bond interactions between alginate and sodium sulfate decahydrate. Variations in mechanical properties of PCM composites with polymer concentrations allow for the formulation of a composite that maintains stable performance after 3D printing.
