Weathering of some Antarctic meteorites: Infrared spectroscopy [PDF]

open access: yes, 1989
P(論文)We studied the degree of weathering of some Antarctic meteorites using the integrated intensity of absorption bands near 3μm to enlarge the data base of the degree of weathering. There is no clear correlation between the integrated intensity and the

The contribution of weathering of the main Alpine rivers on the global carbon cycle [PDF]

open access: yes, 2013
On geological time-scales the carbon fluxes from the solid Earth to the atmosphere mainly result from volcanism and metamorphic-decarbonation processes, whereas the carbon fluxes from atmosphere to solid Earth mainly depend on weathering of silicates and

Operando Visualization of Cathode Water Management in Proton Exchange Membrane Water Electrolyzers Using Synchrotron X‐Ray Radiography

open access: yesAdvanced Science, EarlyView.
The cathode of proton exchange membrane water electrolyzers remains a poorly understood region despite its importance for hydrogen purity and operational safety. Operando synchrotron X‐ray radiography directly visualizes liquid water behavior and uncovers a transition from continuous to pulsating transport, providing new insight into multiphase ...
