Deng, Yanhao; et al. (2021): A comparative review of performance of nanomaterials for Direct Air Capture

Deng, Yanhao; Li, Jia; Miao, Yihe; Izikowitz, David (2021): A comparative review of performance of nanomaterials for Direct Air Capture. In Energy Reports 7, pp. 3506–3516. DOI: 10.1016/j.egyr.2021.06.002.

"This review found that while nanofibers offer effective CO2 uptake under low pressure, they offer poor structural stability – a shortcoming overcome by the diverse structural flexibility found in nanocomposite materials and their comparatively affordable fabrication costs."

Dong, Peixin; et al. (2021): Direct Air Capture via Natural Draft Dry Cooling Tower

Dong, Peixin; Li, Xiaoxiao; Yu, Yuanyuan; Zhang, Zekun; Feng, Junjie (2021): Direct Air Capture via Natural Draft Dry Cooling Tower. In International Journal of Greenhouse Gas Control 109, p. 103375. DOI: 10.1016/j.ijggc.2021.103375.

"In this study, a novel direct air capture (DAC) system, which integrates the conventional natural draft dry cooling towers (NDDCTs) and the current DAC technology, is proposed to lower the operating cost during the CO2 capture process and enhance the cooling effects of NDDCTs in a thermal power plant as well."

Custelcean, Radu; et al. (2021): Direct air capture of CO2 with aqueous peptides and crystalline guanidines

Custelcean, Radu; Garrabrant, Kathleen A.; Agullo, Pierrick; Williams, Neil J. (2021): Direct air capture of CO2 with aqueous peptides and crystalline guanidines. In Cell Reports Physical Science 2 (4), p. 100385. DOI: 10.1016/j.xcrp.2021.100385.

"Here, we demonstrate a promising approach to DAC that combines atmospheric CO2 absorption by an aqueous oligopeptide (e.g., glycylglycine) with bicarbonate crystallization by a simple guanidine compound (e.g., glyoxal-bis-iminoguanidine)."
