Nucleophilic Gallyl Anions Enable Ga─Au Bimetallic Ammonia Activation
Angewandte Chemie, EarlyView.Unlocking gallyl nucleophiles: Counterion control enables formation of an unsupported gallyl─gold complex. Gold coordination induces a polarity switch at gallium, enabling cooperative activation of NH3 and related N─H/O─H substrates under mild conditions.

Angewandte Chemie, EarlyView.This work focuses on how to improve the selectivity and activity of electrocatalytic CO2 reduction to C3+ products, by the integration of electrocatalyst and electrolyte co‐design. We summarize key C3+ formation mechanisms and provide a comprehensive reaction network through thermodynamic analysis.

Rapidly Diversifying Hydrogen‐Bonded Organic Frameworks With Permanent Porosity
Angewandte Chemie, EarlyView.This article reviews diversifying hydrogen‐bonded organic frameworks (HOFs) with permanent porosity reported over the past 15 years, based on the molecular structures of their constituent tectons. Furthermore, several distinctive aspects and concepts are described, such as permanent porosity, isostructural (isoreticular) HOFs, and multicomponent mixed ...

Effects of the 1997-1998 El Niño and 1998-1999 La Niña events on breeding waterbirds and sea lions in the Upper Gulf of California, México [PDF]
Geofísica Internacional, 2003 During 1998 and 1999 I monitored waterbirds nesting on Isla San Jorge, at La Purinera and on Isla Montague, in the northern Gulf of California, as well as sea lions on Isla San Jorge. During El Niño the brown boobies on San Jorge ceased breeding and left
