Highly Porous NiFe Nanofoams Synthesized by Dynamic Hydrogen Bubble Template for Hydrogen Evolution in Alkaline Media

Small Structures, EarlyView.
Nickel is replaced by iron in the synthesis of nanostructured electrodes via dynamic hydrogen bubble template electrodeposition for alkaline electrolysis. The highly porous electrodes are studied by electrochemical analysis, characterized by scanning electron microscopy/energy‐dispersive spectroscopy, and a durability assessment that is applied to the ...

Systematics of Planchonella Pierre: The largest Sapotaceae genus in subfamily Chrysophylloideae

TAXON, EarlyView.
Abstract Planchonella is the largest genus in subfamily Chrysophylloideae (Sapotaceae), believed to circumscribe about 110 species, occurring throughout tropical Asia, Australia, and Oceania, as well as the Seychelles and Hawaii. Previous studies have confirmed the monophyly of Planchonella but also identified problems such as species limits of the ...

The Gold‐Maker of Animal Oil and Prussian Blue Fame — The Chemical and Medicinal Science Philosophy of Johann Conrad Dippel

The Chemical Record, EarlyView.
The radical Pietist Johann Conrad Dippel was a self‐proclaimed adept – a maker of gold and the philosophers’ stone. He was also a magister of theology, a doctor of medicine, and a self‐taught chemist, who coinvented the pigment Prussian Blue together with Johann von Diesbach, became known for his animal pyrolysis oil, his wonder‐wound balm, his ...
