Fertilisation of Flowers by Insects [PDF]

open access: yesNature, 1873
IN my last article on Alpine Gentiana species, I supposed that the chief, if not the only fertiliser of G. bavarica and verna might be Macroglossa stellatarum with its proboscis of 25-28 mm. length. Yesterday, near the Albula pass, I was happy enough to confirm this supposition by direct observation.

Pulsed Oxidative–Reductive Electrolysis Over Dual Cu and Co Single‐Atom Sites for Urea Electrosynthesis

open access: yesAdvanced Materials, EarlyView.
Alternating oxidative–reductive pulses synchronize CO2‐derived *CO and NH3‐derived *NHx intermediates over dual Cu and Co single‐atom sites, enabling urea and ethyl urea formation with a total C─N Faradaic efficiency of 42 ± 4%. In situ spectroscopy and theoretical calculations elucidate complementary Cu and Co functions, while oxidative controls ...
