Technological Pathways to Produce Compressed and Highly Pure Hydrogen from Solar Power.

Hydrogen (H ) produced from renewables will have a growing impact on the global energy dynamics towards sustainable and carbon-neutral standards. The share of green H is still too low to meet the net-zero target, while the demand for high-quality hydrogen continues to rise. These factors amplify the need for economically viable H generation technologies.

Is acute pulmonary embolism more severe in the presence of obstructive sleep apnea? Results from an observational cohort study.

Obstructive sleep apnea (OSA) might influence disease severity in acute pulmonary embolism (PE). 253 survivors of acute PE were evaluated for sleep-disordered breathing by portable monitoring and nocturnal polysomnography. PE patients with an apnea-hypopnoea index (AHI) ≥ 15/h were significantly older (p < 0.
