Summary: The study compared the CO2 absorption capacity of three hybrid solvents based on [Bmim][OAc] and different cosolvents, with [Bmim][OAc]-DEPG250 showing the highest absorption capacity. The addition of DEPG250 significantly reduced the viscosity while maintaining comparable absorption capacity. Additionally, using [Bmim][OAc]-DEPG250 as a solvent resulted in a lower CO2 capture cost compared to aqueous amine solutions due to reduced utility costs.

Summary: The research focuses on the development of absorbing materials with high absorbing capacity and lightweight. MnFe2O4 nanoparticles were prepared using a hydrothermal method, and their size was found to have an impact on the electromagnetic microwave absorption performance. The introduction of diatomite and a three-dimensional polyaniline network further enhanced the absorption capability of the MnFe2O4/PANI/diatomite composite. The absorption mechanism is attributed to impedance matching, conduction losses, polarization losses, and magnetic losses.

Summary: This study presents an electrochemical direct air capture (DAC) method using air-stable redox couple of neutral red, which requires a minimum energy requirement of 65 kJ(e)/mol(CO2). Direct air capture of carbon dioxide is a viable option for mitigating CO2 emissions and their impact on global climate change.

Summary: Superbase-derived task-specific ionic liquids (STSILs) are an attractive and extensively studied system for carbon capture. In this work, carbanion-derived STSILs were developed for efficient CO2 chemisorption via a carboxylic acid formation pathway. The results demonstrate the importance of extended conjugation in the CO2-integrated product for achieving efficient CO2 chemisorption.

Summary: This study evaluated the combination of two aluminosilicates with Na-based alkaline liquid reagents and how they affected the physicomechanical properties of the prepared geopolymers after curing. The results showed that the synthesized geopolymers had an amorphous inorganic structure containing residual crystalline phases and exhibited cold crushing strength and Young's modulus up to 39.4 MPa and 13.4 GPa, respectively. The use of colloidal silica suspension favored the geopolymerization reactions, leading to the development of silicate-free geopolymers with enhanced performance at low temperature.

Summary: For the first time, amino acid groups were added to Fe3O4 nanoparticles to enhance CO2 absorption and desorption. The modified nanoparticles showed higher stability and presence of amino groups, resulting in increased CO2 absorption capacity. Moreover, Fe3O4@arginine, Fe3O4@histidine, and Fe3O4@glycine nanofluids significantly improved CO2 desorption enhancement.

Summary: This study statistically investigated the mass transfer of CO2 absorption in 2-amino-2-methyl-1-propanol (AMP) - piperazine (PZ) - monoethanolamine (MEA), and proposed the optimal condition based on the results. The impact of different parameters on the mass transfer coefficient and CO2 removal percentage was analyzed, and linear or second-order polynomial relationships were established.
