Minor and Trace Element Emissions from Post-Combustion CO2 Capture from Coal: Experimental and Equilibrium Calculations [PDF]

, 2014
Elemental partitioning, including gaseous elemental emissions from pilot scale (25 kWth), post combustion CO2 capture using a Ca-based sorbent, have been investigated for naturally occurring elemental impurities found in limestone, that have the ...

Instantaneous Capture and Mineralization of Flue Gas Carbon Dioxide: Pilot Scale Study

, 2010
Multiple CO2 capture and storage (CCS) processes are required to address anthropogenic CO2 problems. However, a method which can directly capture and mineralize CO2 at a point source, under actual field conditions, has advantages and could help offset ...

Inhibition Mechanism of Amino Acids Against Carbonation-Induced Corrosion in Reinforced Concrete

, 2023
Deterioration of reinforced concrete (RC) structures, due to exposure of steel reinforcing bar (rebar) to aggressive environment, is a major cause of concern in terms of durability and overall structural integrity.

Natural Bone‐Derived Ceramic Scaffolds Functionalized with Chitosan‐Gold, Chitosan‐Magnesium, and Chitosan‐Zinc for Enhanced Antibacterial Activity

Advanced Engineering Materials, EarlyView.
This study reports the development of antibacterial ceramic scaffolds derived from natural bovine bone. The bones were processed through sequential boiling and hydrogen peroxide treatment to remove organic matter, producing porous, mineral‐rich scaffolds.

Compatibility of Methacrylate Based Resins Controls Interfacial Failure and Toughness in 3D‐Printed Multimaterial Composites

Advanced Engineering Materials, EarlyView.
This work shows that the mechanical performance of multimaterial digital light processing (DLP) printed thermoset composites is governed by resin compatibility and interfacial design rather than spatial patterning alone. Brittle and ductile resin combinations produced premature interfacial failure, while graded interfaces and mechanically compatible ...

Effects of Different Carbonation Treatment Methods for Recycled Concrete Aggregate

Buildings
Compared to natural aggregates, recycled concrete aggregates (RCAs) which are derived from construction and demolition (C&D) waste exhibit inferior properties, such as lower density and higher water absorption.
