From Waste to Value: Conversion of Calcium Sulfate to Vaterite via Carbon Capture and Storage
Advanced Functional Materials, EarlyView.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.

Effect of Additives on Mineral Trioxide Aggregate Setting Reaction Product Formation [PDF]
, 2015 Introduction Mineral trioxide aggregate (MTA) sets via hydration of calcium silicates to yield calcium silicate hydrates and calcium hydroxide (Ca[OH]2). However, a drawback of MTA is its long setting time.

Role of Histidine‐Containing Peptoids in Accelerating the Kinetics of Calcite Growth
Advanced Functional Materials, EarlyView.Amphiphilic histidine‐containing peptoids mimic carbonic anhydrase (CA) to accelerate calcite step growth. In the presence of Zn2+, they promote the deprotonation of HCO3−, the desolvation of Ca2+, and the reorganization of interfacial hydration layers, thereby reducing the activation barrier for calcite growth.

Calcium hydroxide curing for accelerated carbonation testing of high volume fly ash cementitious blends [PDF]
, 2016 During wet curing, the alkali concrete compounds, such as calcium hydroxide, can be leached out to the curing solution, due to the pH gradient between concrete and curing solution.

Supported ITZ modification efficiencies via surface coating nanoparticles on aggregate and its influence on properties [PDF]
, 2019 In order to modify the porous interfacial transition zone (ITZ) microstructure of concrete more efficiently, a method of coating aggregate surfaces by using several nanoparticles was evaluated in this study. The compressive strength, chloride penetration

Advanced Functional Materials, EarlyView.This study presents a new hole transporting material (HTM) mechanism for self‐assembled monolayers in near‐infrared organic photodetectors. The formation of zwitterions induces a strong electric field that significantly increases the work function of HTM‐coated indium tin oxide substrates. The devices exhibit low dark current and noise, along with high

Advanced Functional Materials, EarlyView.Fluoroalkyl‐functionalized tin–oxo nanoclusters (N‐TOC6) enable robust pattern formation through ligand crosslinking under EUV exposure without thermal processing. Sn–F coordination mitigates the Lewis acidity of Sn centers, suppressing reactions with airborne molecules and improving post‐exposure pattern stability.

Calcium hydroxide as low cost adsorbent for the effective removal of indigo carmine dye in water
, 2017 Adsorption of indigo carmine dye onto calcium hydroxide was investigated in this work. The variation in the pH, adsorbent dose, dye concentration, duration and the temperature was evaluated.

Aspects of Solvent Chemistry for Calcium Hydroxide Medicaments
Materials, 2017 Calcium hydroxide pastes have been used in endodontics since 1947. Most current calcium hydroxide endodontic pastes use water as the vehicle, which limits the dissolution of calcium hydroxide that can be achieved and, thereby, the maximum pH that can be ...
