Abstract
Vital pulp therapy (VPT) is considered a conservative treatment for preserving pulp viability in caries-induced dental pulp infections. However, bacterial contamination negatively affects dentine-pulp complex repair. The common capping materials show limited antimicrobial effects against some microorganisms. To improve the VPT efficacy, capping materials with increased antibacterial properties and enhanced odontogenic and angiogenic activities are needed. Herein, a SrCuSi4 O10 /gelatin methacrylate(SC/Gel) composite hydrogel has been proposed for infected dental pulp treatment. SrCuSi4 O10 (SC) is a microscale bioceramic composed of assembled multilayered nanosheets that possesses good near-infrared photothermal conversion ability and multiple bioactivities due to sustained Sr2+ , Cu2+ , and SiO3 2- ion release. It is shown that the SC/Gel composite hydrogel efficiently eliminates Streptococcus mutans and Lactobacillus casei and inhibits biofilm formation under photothermal heating, while the ion extract from SC promotes odontogenesis of rat dental pulp stem cells and angiogenesis of human umbilical vein endothelial cells. The as-designed therapeutic effect of SC/Gel composite hydrogel-mediated VPT has been proven in a rat dental pulp infection model and yielded improved dentine-pulp complex repair compared with the commercially used iRoot® BP Plus. This study suggests that the SC/Gel composite hydrogel is a potential pulp-capping material with improved effects on dentine-pulp complex repair in infected pulp.

Abstract
The layered silicates Egyptian Blue (CaCuSi4O10, EB), Han Blue (BaCuSi4O10, HB) and Han Purple (BaCuSi2O6, HP) are known as historic pigments, but they also possess novel optoelectronic properties with great potential for fundamental research and technology. They fluoresce in the near-infrared (NIR) range and can be exfoliated into two-dimensional (2D) nanomaterials (i.e. nanosheets, NS) which retain the photophysical properties of the bulk materials. These and other characteristics fuel the growing excitement of the scientific community about these materials. EB-, HB- and HP-NS have been used in various applications ranging from smart inks, energy storage, bioimaging, to phototherapy and more. In this review article, we report the fundamental properties of these low-dimensional silicate nanomaterials, discuss applications and outline perspectives for the future.

Towards Efficient Luminescent Solar Energy Concentrator Using Cuprorivaite Infrared Phosphor (CaCuSi 4O 10)-Effect of Dispersing Method on Photoluminescence Intensity. MATERIALS 2021; 14:ma14143952. [PMID: 34300871 PMCID: PMC8307361 DOI: 10.3390/ma14143952] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/02/2021] [Revised: 07/08/2021] [Accepted: 07/12/2021] [Indexed: 11/16/2022]
Abstract
Cuprorivaite, also known as Egyptian blue (EB), CaCuSi4O10, has been utilized as an important blue pigment for thousands of years. It shows a 430–800 nm broad excitation band and an intense 910–920 nm near-infrared (NIR) emission peak at room temperature. The application that motivates the current research is for luminescent solar concentrator (LSC) usage. Current technology for this purpose relies on high near-infrared reflectance. This article addresses the investigation of the relationship between dispersing methods and photoluminescence (PL) intensity. Mechanical grinding methods investigated in the study were: horizontal bead mill, exfoliation and three-roll mill. The initial aim of the study was to verify if the proposed methods do not damage PL. To the surprise of the authors, three-roll mill treatment enhanced PL by nearly 50% without altering the morphology of the powder. An X-ray diffraction study suggested slight alterations in the crystal lattice.

Abstract
Motivated by the recent experimental advances in exfoliating Egyptian blue monolayers, we have carried out extensive calculations using density functional theory to understand their geometry, stability, mechanical properties, electronic structures, and magnetism. Upon exfoliation from the bulk, XCuSi4O10 (X = Ca, Sr, and Ba) monolayers are found to change symmetry from tetragonal to orthorhombic. They all satisfy Born criteria and are mechanically stable. Each Cu site carries a magnetic moment of 1.0 μB but with degenerate ferromagnetic and antiferromagnetic coupling states. From Ca to Sr and Ba, as the atomic number increases, the thickness, elastic constants, Young's moduli, and Poisson's ratios of the monolayers increase, while the band gaps decrease. Applying strain can tune the magnitude of energy band gaps, but the direct gap feature remains. Complementing the widely studied graphene, MXenes, black phosphorus, and dichalcogenide sheets, the Egyptian blue monolayers add additional features to the family of two-dimensional materials.

Abstract
We describe the first hydrothermal synthesis of CaCuSi4 O10 as micron-scale clusters of thin platelets, distinct from morphologies generated under salt-flux or solid-state conditions. The hydrothermal reaction conditions are surprisingly specific: too cold, and instead of CaCuSi4 O10 , a porous calcium copper silicate forms; too hot, and calcium silicate (CaSiO3 ) forms. The precursors also strongly impact the course of the reaction, with the most common side product being sodium copper silicate (Na2 CuSi4 O10 ). Optimized conditions for hydrothermal CaCuSi4 O10 formation from calcium chloride, copper(II) nitrate, sodium silicate, and ammonium hydroxide are 350 °C at 3000 psi for 72 h; at longer reaction times, competitive delamination and exfoliation causes crystal fragmentation. These results illustrate that CaCuSi4 O10 is an even more unique material than previously appreciated.
