Flight activity of the peach fruit moth, Carposina sasakii (Lepidoptera: Carposinidae), measured by a flight mill

open access: yesApplied Entomology and Zoology, 2004
The effects of temperature, age and mating status on the flight activity of Carposina sasakii were examined using a flight mill system. Flight measurements were carried out for 24 h under dark conditions. No significant difference was observed for the total flight duration of 2-day-old moths at temperatures between 14 and 26°C.

Superionic Amorphous Li2ZrCl6 and Li2HfCl6

open access: yesAdvanced Materials, EarlyView.
Amorphous Li2HfCl6 and L2ZrCl6 are shown to be promising solid‐state electrolytes with predicted ionic conductivities >20 mS·cm−1. Molecular dynamics simulations with machine‐learning force fields reveal that anion vibrations and flexible MCl6 octahedra soften the Li coordination cage and enhance mobility. Correlation between Li‐ion diffusivity and the

The Maribo CM2 meteorite fall - survival of weak material at high entry speed

open access: yes, 2019
High entry speed (> 25 km/s) and low density (< 2500 kg/m3) are two factors that lower the chance of a meteoroid to drop meteorites. The 26 g carbonaceous (CM2) meteorite Maribo recovered in Denmark in 2009 was delivered by a superbolide observed by ...
