The carbon dioxide (CO) capture and utilization strategy has emerged as an innovative and multifaceted approach to counteract carbon emissions. In this study, a highly porous muffin polyhedral barium (Ba) ̵ organic framework (BaTATB; HTATB = 4,4',4″--triazine-2,4,6-triyl-tribenzoic acid) was synthesized solvothermally. The three-dimensional honeycomb pore architectures were densely populated with Lewis acidic Ba(II) metal sites and basic nitrogen-rich triazines.

Primary and secondary atmospheric pollutants, including carbon monoxide (CO), carbon dioxide (CO), nitrogen oxides (NO), ozone (O), sulphur dioxide (SO) and particulate matter (PM/PM) with associated heavy metals (HMs) and micro- and nanoplastics (MPs/NPs), have the potential to influence and alter interspecific interactions involving insects that are responsible for providing essential ecosystem services (ESs). Given that insects rely on olfactory cues for vital processes such as locating mates, food sources and oviposition sites, volatile organic compounds (VOCs) are of paramount importance in interactions involving insects. While gaseous pollutants reduce the lifespan of individual compounds that act as olfactory cues, gaseous and particulate pollutants can alter their biosynthesis and emission and exert a direct effect on the olfactory system of insects.

Understanding the impact of surface copper valence states on the distribution of electrochemical carbon dioxide products is critical. Herein, CuO@Cu2O with a Cu2+/Cu+ interface was fabricated using wet chemical etching approach. The hollow shape offered a large region for gas adsorption, while the interfacial mixed chemical state of Cu2+/Cu+ with tunable control ratio raised the local density of CHO* and accelerated the carbon-carbon coupling reaction.

In coronary artery bypass grafting (CABG), the use of the left internal mammary artery (LIMA) is considered the gold standard. The conventional technique of using electrocautery for LIMA harvesting is associated with adverse events. In this study, we used a different technique that combined carbon dioxide with electrocautery to harvest LIMA and compared it with the conventional electrocautery method.
