Summary: Mixed matrix membrane materials (MMMs) are being studied for gas separation, and this research investigates the optimal combination of filler and matrix for maximum selectivity. Computational simulations show that adding a filler with similar permeability to the faster gas in the matrix can result in the highest selectivity change, and these results are compared to analytical solutions from various models. The role of interfacial defects in altering the transport properties of mixtures through the MMMs is also examined.

Summary: This study investigates the potential utility of 2D MXenes as nanofillers to enhance the gas separation performance of polydimethylsiloxane (PDMS) membrane. Mixed-matrix membranes were fabricated by incorporating multilayer MXene (ML-MXene) and single-layer MXene (D-MXene) into PDMS matrices, and the addition of MXene improved the separation capacity of the rubbery dense layers. The optimized D-MXene-loaded mixed-matrix membrane at 1 wt% loading demonstrated a 64.1% increase in CO2 permeability and a 21.3% increase in CO2/N2 selectivity compared to pure PDMS membrane.

Summary: Ionic liquids are attractive solvents for CO2 capture due to their low vapor pressure, thermal stability, wide chemical solubility window, and tunable physical and chemical properties. Ionic liquid membranes (ILMs), including various types such as supported ILMs, room temperature ILMs, functionalized ILMs, polyionic liquid membranes, composite membranes, IL-gel membranes, and mixed matrix membranes, have been studied extensively for CO2 separation. The permeability, selectivity, and stability of these membranes have been reported and discussed, with considerations such as the addition of ionic liquids, proper size of porous support, and selection of membrane support.

Summary: In this study, the first three (TiO, ZrO, and HfO) WC-type topological semimetal compounds in transition metal oxides were systematically investigated through first-principles calculation. The results showed that these compounds are structurally, thermodynamically, mechanically, and dynamically stable and can be easily synthesized. Among them, TiO exhibited unique properties with the co-existence of 3-fold fundamental particles in the electronic band structure and phonon dispersion, providing a platform to explore the multifunctional quantum-mechanical properties of these particles at the atomistic level. The spin-orbital coupling effect was ignored in TiO due to the light atomic masses of Ti and O elements, and their electronic and topological properties were extensively studied.

Summary: Sixteen fuberidazole derivatives were synthesized and characterized as potential new anticancer bioreductive prodrugs. In vitro tests on chosen hypoxic cancer cells showed that eight substances (Compound 5a, 5c, 5d, 5e, 5g, 5h, 5i, and 5m) exhibited promising cytotoxicity compared to the standard control. In silico studies were conducted to gain insights into the structure-activity relationship, pharmacochemical strength, and mode of interactions responsible for their action. DFT calculations revealed specific properties of the compounds, with 5b having the lowest Delta ET and 5i showing the highest beta tot, alpha ave, and dipole moment. This study presents a novel class of fuberidazole derivatives with selectivity toward hypoxic cancer cells.

Summary: Heavy metals, resulting from human activities, are widely present in water bodies and accumulate in the body over time, posing serious health problems. Therefore, improving the sensing performance of electrochemical sensors for the detection of heavy metal ions (HMIs) is crucial. In this study, a cobalt-derived metal-organic framework (ZIF-67) was synthesized and incorporated onto the surface of graphene oxide (GO) using a simple sonication method. The synthesized material (ZIF-67/GO) was characterized and used to create a sensing platform for the individual and simultaneous detection of heavy metal ion pollutants (Hg2+, Zn2+, Pb2+, and Cr3+), with detection limits below the permissible limit set by the World Health Organization. This is the first report of HMIs detection using a ZIF-67 incorporated GO sensor, which can successfully determine Hg+2, Zn+2, Pb+2, and Cr+3 ions simultaneously with lower detection limits.

Summary: In this research, the adsorption mechanisms of CO2 onto Malaysian coals were investigated, and it was found that the dry S1 coal showed the highest CO2 adsorption capacity. The results suggested that CO2 adsorption onto coal matrix is favorable, spontaneous, and the adsorbed CO2 molecules accumulate more onto coal matrix. These findings have significant implications for a more accurate measurement of CO2 injection into Malaysian coalbed seams.
