Summary: In this study, a high-throughput computational screening of around 12,000 experimentally realizable metal-organic framework (MOF) structures was conducted to identify the best candidates for separating methane from ethane and propane at ambient conditions. Two MOFs, AZIVAI and BEWCUD, were found to perform the best for this separation. The research also revealed a trade-off relation between selectivity and working capacity, with different behaviors of heat of adsorption on these two metrics.

Summary: This study demonstrates the potential of ultrasound emulsification to form whey protein-enriched double emulsions with minimum food-grade emulsifiers to fortify the protein content of cheese and other food products. The encapsulation loading rate of whey proteins within the double emulsion droplets was investigated in relation to ultrasound parameters and formulation loading rates. The results showed that high encapsulation loading rates can be achieved using ultrasound with comparable oil droplet diameters to native milk fat globules.

Summary: Engineering heterostructured membranes using different two-dimensional materials is an effective way to design membranes for selective gas molecule transport. In this study, a simple and versatile pyro-layering approach was developed to fabricate heterostructured membranes using boron nitride nanosheets as the scaffold and graphene nanosheets derived from a chitosan precursor as the filler. The rearrangement of graphene nanosheets during the pyro-layering treatment formed precise nanochannels and spacing, enabling selective hydrogen transport.

Summary: Metal-organic frameworks (MOFs) -based composites have been extensively studied for the removal of metal ion pollutants from water. MOFs are considered excellent metal ion adsorbents due to their large surface area, tunable pores, and abundance of active sites. MOF composites, combining MOFs with materials such as magnetic particles, polymers, and graphene oxide, have been developed to enhance the metal adsorption capacity. This article provides an overview of current MOF-based composites, discussing their synthesis techniques, applications, and performance compared to pure MOFs and other adsorbents.

Summary: Porous liquids have advantages over solid adsorbents and physical solvents in various fields. The inherent pores of a well-designed system can have molecular recognition capabilities, combining the advantages of both liquid and solid phases. While solid porous systems have selectivity towards different gas moieties, the ease of use and processing of liquids provide significant opportunities. Rapid mass transfer and fluidity in liquids contribute to their rapid gas solubility and diffusion. Improving existing technologies for gas capture is crucial for applications such as pollution removal, storage, or catalysis. Many of these technologies rely on the porosity of solids like zeolites or metal-organic frameworks (MOFs). In this study, 60 solvents were examined for their suitability in Type II/III porous liquids based on their molecular dimensions and shape. Six rapid screening modeling methodologies were used to assess the dimensions of the solvent molecules. Several assessments were performed to support the design and generation of novel porous liquids by comparing solvents, gases, and MOFs' properties.
