Observation of the depassivation effect of attrition on magnesium silicates' direct aqueous carbonation products

Frontiers in Climate, 2022
The main obstacle to the aqueous carbonation of non-serpentinised magnesium silicates is the formation of surface passivation layers, which severely limits the reaction rate and thus the overall efficiency of the process.

Carbonation and Corrosion Problems in Reinforced Concrete Structures

Buildings, 2022
Reinforced concrete (RC) has been commonly used as a construction material for decades due to its high compressive strength and moderate tensile strength. However, these two properties of RC are frequently hampered by degradation.

Design of Carbon–Carbon Ylides

Angewandte Chemie
Abstract Here, we have reported the computational design of a new class of ylides, elusive carbon–carbon ylides featuring zwitterionic σ‐bonds, derived from the norbornane‐2,6‐dione framework. Utilizing the state‐of‐the‐art computational methods, we have demonstrated that appropriate substitutions on this scaffold
