A review on carbonation in cement composites and its impacts on durability and potential for CO₂ sequestration

Journal of Materials and Engineering Structures
Carbonation is a key process affecting the durability, strength, and environmental impact of concrete. While it refines pore structure and enhances strength, it also lowers alkalinity, leading to reinforcement corrosion risks.

Engineering a Fluorinated AlPO4 Interface: Toward High Initial Coulombic Efficiency and Stable Oxygen Redox in Li‐Rich Layered Oxide Cathodes

Advanced Functional Materials, EarlyView.
We report a chemically incorporated fluorinated AlPO4 (AlPO4‐F) architecture that functions as a multifunctional “interfacial fortress” for Li‐rich layered oxides (LLOs). By modulating the surface potential to –32.16 mV, this architecture enriches Li+ concentration and repels detrimental electrolyte anions.

Dynamic carbon footprint trade-off between carbonation curing, mineral carbonation and natural carbon uptake in concrete blocks

Environmental Research Letters
Concrete accounts for approximately 7% of global anthropogenic CO $ _2$ emissions, nearly two-thirds of which are hard-to-abate limestone calcination emissions that are partially offset through natural carbonation. This study presents a dynamic cradle-to-

Near‐Infrared Light‐Activated Polydopamine Nanoparticles Conjugated With Transferrin Peptides for Enhanced Brain Accumulation

Advanced Healthcare Materials, EarlyView.
This study demonstrates that Tf‐PDA NPs combine a receptor‐mediated targeting with mild photothermal activation to enhance nanoparticle accumulation in the brain. NIR‐activated Tf‐PDA NPs increase BBB permeability to NPs in vitro and in vivo without inducing cytotoxicity or adverse immune responses.

Novel accelerated carbonation methods based on deep breathing analogous and prediction model for pressurized carbonation of concrete

Scientific Reports
This research proposes a novel deep breathing analogy (DBA) accelerated carbonation process. Inspired by the breathing mechanism of human lungs, the DBA method involves injecting pure CO2 into a reaction chamber at a specific pressure (inspiration) and ...
