Summary: In this study, the activation energy of kink incorporation and the vibrational frequency of particles on the growth interface of colloidal crystals with attractive interactions were successfully estimated using two different approaches. The results showed that the method of direct observation of particle movements was more accurate than the Arrhenius plot method. This study quantitatively estimated the activation energy of kink incorporation and the vibrational frequency of particles on the growth interface, which contributes significantly to the understanding of crystal growth mechanisms.

Summary: This study investigated the hydration of alite, a major clinker phase in Portland cement, in seawater with added common salt solutions. It was found that the addition of salts accelerated the hydration rate of alite, leading to an increase in the formation of C-S-H and portlandite at early ages. Different salts also influenced the morphology and polymerization degree of C-S-H, with gypsum and brucite formed as new hydration products in specific salt systems.

Summary: This study presents a method for the facet-controlled synthesis of nanocrystals with an ultrathin shell made of a nearly equimolar RuRhPdPt quaternary alloy, showing greatly enhanced activity toward ethanol oxidation. The core-shell nanocubes demonstrate good thermal and electrochemical stability in terms of both geometrical shape and elemental composition, making them a promising candidate for various thermal and electrochemical reactions. The synthetic approach can potentially be extended to fabricate multimetallic catalysts with enhanced activities.

Summary: A first principles-based multi-oxide inclusion (MOI) kinetic model is proposed to predict the transient evolution of oxide inclusion composition in secondary steelmaking processes. The model takes into account the thermodynamics and kinetics of different stoichiometric oxide inclusions, providing information about individual oxide particles rather than average inclusion composition. When coupled with a steel-slag model, the predictions of the MOI model show good agreement with experimental measurements, demonstrating the linkages between inclusion precipitation sequence and compositional variables.

Summary: The heat-up synthesis routes are widely used for large-scale production of nanoparticles with narrow size distribution and high crystallinity. An in situ SAXS/WAXS experiment was conducted to investigate the nucleation and growth kinetics of iron oxide nanoparticles during heat-up synthesis, revealing a three-phase characteristic sequence and a complex intermediate phase. A nonclassical nucleation and growth theory was developed to account for an amorphous transient state and particle aggregation, allowing for a quantitative understanding of nanoparticle nucleation and growth kinetics.

Summary: The synthesis of Alite-ye'elimite cement (ACSA) through the single firing process at lower temperature with the addition of phosphorous slag and copper slag has the potential to become a low-energy Portland cement. The coexistence of alite and ye'elimite can improve cement quality, and controlling the activation energy during their formation and decomposition processes is crucial for their better coexistence in cement production. Results showed that the diffusion model can determine their apparent activation energy, with temperature-dependent activation energy for alite and ye'elimite formation and decomposition.

Summary: This study investigates the influence of hydrothermal synthetic conditions on the properties of C-S-H seeds and reveals the correlations between C-S-H seeds properties, hydration kinetics, and paste performances. It is found that low reactant concentrations and calcium-to-silicon ratios facilitate the production of C-S-H seeds with small size and high purity. Using C-S-H seeds with high effective surface area accelerates the hydration process of cement, resulting in refined pore structure and enhanced strength.

Summary: This study developed a numerical framework to investigate the combined attack of sulfate and chloride ions on cementitious materials in marine and saline environments. The study quantified various chemical reactions and solved the electrostatic potential caused by multi-ion coupling. The results showed that neglecting the multi-ions coupling effect could result in an underestimated chemical coupling strength in competitive chloride-sulfate binding.

Summary: This study aimed to improve the carbonation efficiency and reduce processing time of recycled concrete aggregates (RCAs). Wet carbonation with seawater was found to be more efficient than dry carbonation, leading to significant reduction in water absorption and increase in density of RCAs. The compressive strength of recycled aggregate concrete (RAC) prepared with 1-hour seawater carbonated RCAs was also improved. The formation of ettringite and calcite under wet carbonation contributed to the increased density and strength, as well as improved bond strength in the interfacial transition zone of RAC. Seawater presents several advantages as a medium for wet carbonation, including its abundant availability, CO2 capture capacity, and accelerated hydration and carbonation.

Summary: Decalcification of calcium silicate hydrates (C-S-H) is an important issue for the long-term safety of cement-based infrastructures. Using molecular simulations, this study reveals an important mechanism of accelerated C-S-H decalcification in seawater, which involves ion exchange between surface Ca and electrical double layers, resulting in a decrease in Ca dissolution free energy. This finding enhances the understanding and prediction of cementitious materials' degradation.

Summary: Low-temperature low-field nuclear magnetic resonance was used to analyze icing in water saturated white cement paste specimens during the freeze-thaw process at different temperatures. The experimental results were compared with classical theory, showing agreement at certain temperatures but discrepancies at others. New equations were proposed based on the analysis of specimens saturated with different solutions to relate the volume of frozen water to temperature during freezing and thawing of cementitious materials.

Summary: This study analyzes the chemical structure and morphology of magnesium silicate hydrate (MSH) grown under different concentration ratios and temperatures. The results show that increasing the magnesium to silicon ratio reduces silicate polymerization in MSH, and at higher temperatures and longer reaction times, oriented attachment of nanoparticles and enhanced crystallinity are observed. These findings provide insights into the precise chemical synthesis of MSH and its widespread use as a binder in construction.
