In the ancient microbial Wood-Ljungdahl pathway, carbon dioxide (CO) is fixed in a multistep process that ends with acetyl-coenzyme A (acetyl-CoA) synthesis at the bifunctional carbon monoxide dehydrogenase/acetyl-CoA synthase complex (CODH/ACS). In this work, we present structural snapshots of the CODH/ACS from the gas-converting acetogen , characterizing the molecular choreography of the overall reaction, including electron transfer to the CODH for CO reduction, methyl transfer from the corrinoid iron-sulfur protein (CoFeSP) partner to the ACS active site, and acetyl-CoA production. Unlike CODH, the multidomain ACS undergoes large conformational changes to form an internal connection to the CODH active site, accommodate the CoFeSP for methyl transfer, and protect the reaction intermediates.

Sulfur dioxide (SO), a pervasive air pollutant, poses significant environmental and health risks, necessitating advanced materials for its efficient capture. Nanoporous organic polymers (NOPs) have emerged as promising candidates; however, their development is often hindered by high synthesis temperatures, complex precursors, and limited SO selectivity. Herein, we report a room-temperature, cost-effective synthesis of carbazole-based nanoporous organic polymers (CNOPs) using 1,3,5-trioxane and paraldehyde, offering a significant advancement over traditional Friedel-Crafts alkylation methods.

This study aimed to evaluate the concentrations of sulfur dioxide (SO2) and nitrogen oxides (NOX) around the Qom (a province in Iran) combined cycle power plant in relation to seasonal variations and fuel type from December 2014 to May 2015. Passive sampling was used in three monitoring sites around the power plant to assess noncarcinogenic health risks associated with exposure to SO2 and NOX. Results showed the higher concentrations of NOX and SO2 in winter than in spring.

Traditionally, α-olefins have been regarded as non-homopolymerizable substrates in textbook examples. However, they have the ability to copolymerize with sulfur dioxide, leading to the creation of alternating copolymers. These commodity poly(olefin sulfone)s exhibite a wide array of applications.

In the era of global warming, the conversion of carbon dioxide into high-value products has become a widely scrutinized emerging mitigation strategy. Metalation of bpy-containing MOF-253 led to the synthesis of MOF-253-0.5Ag, which acts as an efficient catalyst for the carbonylative cyclization of CO with alkyne molecules (such as propynyl alcohols and propynyl amines) at room temperature and ambient CO pressure, yielding the corresponding α-alkyl cyclic carbonates and oxazolidinones, thus endowing the catalytic system with bifunctional characteristics.
