Energy Harvesting From CO2 Emissions: The Role of Gas Concentration, Flow, and Supporting Electrolyte

Advanced Sustainable Systems, Volume 10, Issue 8, August 2026.
Energy harvesting through Carbon dioxide capture has already been demonstrated to be feasible. However, a deeper understanding of the boundary conditions governing the process is still required. In this study, particular attention was devoted to the influence of external factors on harvesting performance.

Use of warm carbon dioxide insufflators does not affect intra-colonic gas temperature and has no effect on polyp detection rate during colonoscopy – a randomized controlled trial

Endoscopy International Open, 2017
Background and study aims Methods to improve polyp detection during colonoscopy have been investigated, with conflicting results for warm water irrigation. Carbon Dioxide (CO2) warmed to 37 °C may have similar or more pronounced effects on bowel motility.

3D Electrical Impedance Tomography of Regional Ventilation During Jet Ventilation: A Pilot Study

Laryngoscope Investigative Otolaryngology, Volume 11, Issue 4, August 2026.
ABSTRACT Objectives Low‐frequency jet ventilation (LFJV) is commonly used in laryngotracheal surgery when intubation is not feasible. However, limited understanding of regional ventilation and distal airway pressures raises safety concerns and restricts broader adoption.

Solid-liquid equilibria for the dimethyl ether plus carbon dioxide binary system [PDF]

, 2010
A recently built experimental setup was employed for the estimation of the solid-liquid equilibria of alternative refrigerants systems. The behavior of dimethyl ether (DME) + carbon dioxide was measured down to temperatures of 131.6 K.

CO2 vs. air insufflation in endoscopic ultrasonography: a prospective study

Endoscopy International Open, 2019
Background and study aims Carbon dioxide (CO2) is being increasingly used for insufflation during endoscopy for safety and better tolerance. The role of CO2 during endoscopic ultrasonography (EUS) has not been studied yet. Our main aim was to compare the
