Most of the porous materials used for acetylene/carbon dioxide separation have problems poor stability and high energy requirements regeneration, which significantly hinder their practical application in industries. Here, we report a novel calcium-based metal–organic framework (NKM-123) with excellent chemical against water, acids, bases. Additionally, it has exceptional thermal stability, retaining its structural integrity at temperatures up to 300 °C. This material exhibits promising potential separating C2H2 CO2 gases. Furthermore, demonstrates an adsorption heat 29.3 kJ mol–1 C2H2, is lower than that observed majority MOFs C2H2/CO2 separations. The preferential over confirmed by dispersion-corrected density functional theory (DFT-D) calculations. In addition, industrial feasibility NKM-123 transient breakthrough tests. robust cycle performance during multiple tests show great light hydrocarbons.

Solubility plays a critical role in many aspects of research (drugs to materials). parameters are very useful for selecting appropriate solvents/non-solvents various applications. In the present study, Hansen solubility predicted using machine learning. More than 40 models tried search best model. Molecular descriptors and fingerprints used as inputs get comparative view. Machine learning trained molecular have shown higher prediction ability model fingerprints. their potential be easy fast compared density functional theory (DFT)/thermodynamic approach. creates "black box" connection properties. Therefore, minimal computational cost is required. With help best-trained model, green solvents selected small molecule donors that organic solar cells. Our introduced framework can select cells an way.

Non-fused ring-based OSCs are an excellent choice, which is attributed to their low cost and flexibility in applications. However, developing efficient stable non-fused still a big challenge. In this work, with the intent increase Voc for enhanced performance, seven new molecules derived from pre-existing A-D-A type A3T-5 molecule proposed. Different important optical, electronic efficiency-related attributes of studied using DFT approach. It discovered that newly devised possess optimum features required construct proficient OSCs. They small band gap ranging 2.22-2.29 eV planar geometries. Six proposed have less excitation energy, higher absorption coefficient dipole moment than both gaseous solvent phases. The A3T-7 exhibited maximum improvement optoelectronic properties showing highest λmax at 697 nm lowest Ex 1.77 eV. lower ionization potential values, reorganization energies electrons interaction coefficients molecule. six developed (Voc 1.46-1.72 eV) = 1.55 eV). Similarly, almost all except W6 fill factor compared reference. This remarkable efficiency-associated parameters FF) proves these can be successfully used as advanced version terthiophene-based future.
