摘要:Membranes for hydrogen-carbon dioxide (H-2-CO2) gas separation have potential applications as energy-efficient components in carbon capture technology. Mixed-matrix membranes (MMMs), which are composed of polymers and filler materials such as metal-organic frameworks (MOFs), are used to achieve a good separation performance by leveraging the intrinsic benefits of each component. However, developing robust interfacial compatibility between polymers and filler materials is a critical challenge. ...

摘要:Jupiter's moon Europa has a subsurface ocean beneath an icy crust. Conditions within the ocean are unknown, and it is unclear whether it is connected to the surface. We observed Europa with the James Webb Space Telescope (JWST) to search for active release of material by probing its surface and atmosphere. A search for plumes yielded no detection of water, carbon monoxide, methanol, ethane, or methane fluorescence emissions. Four spectral features of carbon dioxide (CO2) ice were detected; the...

摘要:Immense violence and corruption in Mexico, and their connections to illegal drugs in the United States, are a great problem of our time. Mexico's homicide rate in 2022 was 25 per 100,000, similar to Colombia's and more than triple the US rate. Measuring corruption is notoriously difficult, but some Mexican criminal organizations have a history of intimidating and bribing government officials (1). On page 1312 of this issue, Prieto-Curiel et al. (2) take on two important tasks: estimating how m...
