Carbon capture and utilization (CCU) covers an array of technologies for valorizing carbon dioxide (CO). To date, most mature CCU technology conducted with capture agents operates against the CO gradient to desorb CO from capture agents, exhibiting high energy penalties and thermal degradation due to the requirement for thermal swings. This Perspective presents a concept of Bio-Integrated Carbon Capture and Utilization (BICCU), which utilizes methanogens for integrated release and conversion of CO captured with capture agents. BICCU hereby substitutes the energy-intensive desorption with microbial conversion of captured CO by the methanogenic CO-reduction pathway, utilizing green hydrogen to generate non-fossil methane.

The capture of carbon dioxide (CO) is crucial for reducing greenhouse emissions and achieving net-zero emission goals. Metal-organic frameworks (MOFs) present a promising solution for carbon capture due to their structural adaptability, tunability, porosity, and pore modification. In this research, we explored the use of a copper (Cu(II))-based MOF called .

There is an urgent need for inexpensive, functional materials that can capture and release CO under industrial conditions. In this context, MgO is a highly promising, earth-abundant CO sorbent. However, despite its favorable carbonation thermodynamics and potential for high gravimetric CO uptakes, MgO-based CO sorbents feature slow carbonation kinetics, limiting their CO uptake during typical industrial contact times.

Background: A grapevine crown gall tumor strain, sp. strain Rr2-17 was previously reported to accumulate copious amounts of diverse quorum sensing signals during growth. Genome sequencing identified a single luxI homolog in strain Rr2-17, suggesting that it may encode for a AHL synthase with broad substrate range, pending functional validation.

By conducting a bibliometric analysis of 1997 scholarly publications on carbon neutrality and zero carbon emissions from 2019 to 2022, it is found that reviews of quantitative socioeconomic modeling research remain limited. To address this issue, a comprehensive review of carbon neutrality research, specifically, a systematic and synergistic review of the literature from a socioeconomic modeling perspective, is needed. The 20 clustering labels in the four largest clusters are summarized as main research streams, that is, carbon emission reduction, carbon sink and carbon capture and storage according to the definition of carbon neutral.

Floodplain wetlands are biologically rich and productive ecosystems that can capture carbon (C) from the atmosphere through macrophytes and phytoplanktons and hold it in soil for a long time thus playing a critical role in mitigating climate change. The Assam state of India has about 1392 floodplain wetlands engulfing around 100,000 ha area in the Brahmaputra and Barak River basin. In the present study, five different wetlands in the middle Assam viz.
