Synergetic Hybridization Strategy to Enhance the Dynamicity of Poorly Dynamic CO2‐derived Vitrimers achieved by a Simple Copolymerization Approach

Advanced Functional Materials, Volume 35, Issue 2, January 9, 2025.
A novel strategy is proposed to obtain performant catalyst‐free dynamic networks from a poor dynamic network and a non‐dynamic network. Such copolymerization strategy leads to straightforward, and industrially relevant dynamic networks. While such a mix is expected to lead to even worse dynamic behavior, an outstanding synergy resulting in a highly ...

High‐resolution cathodoluminescence of calcites from the Cold Bokkeveld chondrite: New insights on carbonatation processes in CM parent bodies

Meteoritics &Planetary Science, Volume 59, Issue 9, Page 2432-2452, September 2024.
Abstract Carbonates, as secondary minerals found in CM chondrites, have been widely employed for reconstructing the composition of the fluids from which they precipitated. They also offer valuable insights into the hydrothermal evolution of their parent bodies.

Low-temperature carbonatization of metal oxides

Energy Procedia, 2019
In the present work carbonatization of selected metal oxides was investigated at temps. below 100 °C and CO2 pressures of 1-55 bar (25 °C) and 110 bar (60 °C) by in-situ powder diffraction, as well as expts. in a pressure reactor. Moisture was confirmed to be a crucial requirement for any successful carbonatization, as under dry conditions always the ...

Combined carbonatation and sulphitation in cane sugar refining

, 2014
M.Tech. (Chemical Engineering)Laboratory and pilot plant trials were carried out on a modified carbonatation process to reduce overall refining costs. Sulphur dioxide dosages of less than 250ppm on brix were added to carbonatated liquors.

Carbonatation atmosphérique des systèmes cimentaires à faible teneur en portlandite [PDF]

, 2013
Reaction of gaseous atmospheric CO2 with calcium-bearing phases in concrete infrastructure components is known to cause a lowering of alkalinity, leading to depassivation and corrosion of rebars.
