Methane Beneath Greenlands Ice Sheet Is Being Released [PDF]

open access: yes
Methane is a potent greenhouse gas, but a complete accounting of global methane sources and sinks is still ongoing. Sediments beneath glaciers and ice sheets harbour carbon reserves that, under certain conditions, can be converted to methane.

Carbazole‐Based Thin Microporous Polymer Films for Photocatalytic Hydrogen Evolution

open access: yesAdvanced Materials, EarlyView.
Photocatalytic hydrogen evolution with electropolymerized microporous films enable a direct and scalable process for the production of industrial relevant amounts of hydrogen gas. For developing cost‐ and material‐effective devices it is beneficial to increase the accessible outer surface area via microstructuring and stacking of polymeric films ...

Spatial Coordination Structure‐Driven Enzyme‐Like Selectivity in Single‐Atom Nanozymes

open access: yesAdvanced Materials, EarlyView.
Sun et al. reviews recent progress in enhancing the enzyme‐like catalytic selectivity of SAzymes through the rational design of their spatial coordination structures. They emphasize the structure‐activity relationships of various attributes of these coordination structures in promoting selective catalytic behavior, the strategic design of coordination ...
