In Situ Diffraction and Ex Situ Transmission X‐Ray Microscopy Studies of Solid‐State Upcycling for NMC Cathodes

open access: yesAdvanced Energy Materials, EarlyView.
Description of attached TOC figure: Phase evolution observed from in situ X‐ray diffraction experiments during upcycling of NMC622 is shown in a contour plot in the center. 3D nickel XANES maps generated using variable energy transmission X‐ray microscopy are presented on the left and right to capture the change in the distribution of nickel during ...

Latitudinal variation in morphology in two sympatric damselfly species with contrasting range dynamics (Odonata: Coenagrionidae)

open access: yesEuropean Journal of Entomology, 2008
Geographic range expansion is one of the best documented macroecological consequences of climate change. A concomitant change in morphology has been demonstrated in some species. The relationship between latitudinal variation in morphology (e.g. Bergmann'

Odonate species occupancy frequency distribution and abundance–occupancy relationship patterns in temporal and permanent water bodies in a subtropical area

open access: yesEcology and Evolution, 2020
This paper investigates species richness and species occupancy frequency distributions (SOFD) as well as patterns of abundance–occupancy relationship (SAOR) in Odonata (dragonflies and damselflies) in a subtropical area.

NOTES ON NOVA SCOTIAN DRAGONFLIES [PDF]

open access: yesThe Canadian Entomologist, 1894
(In 1889 and 1890, Mr. William Sheraton, of Wycliffe College, Toronto, collected some Odonata at Pictou, Nova Scotia, for me. At the end of the collecting season of 1889, he sent me a letter containing his field notes on the specimens captured. These observations are so interesting, in my opinion, that any publication in which they appear ought also to

Optical observations of PSR J2021+3651 in the Dragonfly Nebula with the GTC

open access: yes, 2015
PSR J2021+3651 is a 17 kyr old rotation powered pulsar detected in the radio, X-rays, and $\gamma$-rays. It powers a torus-like pulsar wind nebula with jets, dubbed the Dragonfly, which is very similar to that of the Vela pulsar.

Cathode Upcycling for Direct Recycling of Lithium‐Ion Batteries Using a Precipitation Approach

open access: yesAdvanced Energy Materials, EarlyView.
To improve the circularity of lithium‐ion batteries, researchers develop a low‐cost method to increase the energy density of directly recycled cathodes. Through a precipitation process, low‐nickel materials are converted to high‐nickel compositions. Using synchrotron 3D X‐ray imaging and diffraction, they track nickel diffusion during high‐temperature ...

\u3ci\u3eGomphus Spicatus\u3c/i\u3e (Odonata: Gomphidae) Rediscovered in Illinois and \u3ci\u3eLibellula Semifasciata\u3c/i\u3e (Odonata: Libellulidae) Recorded Near Wisconsin [PDF]

open access: yes, 2018
(excerpt) Gomphus spicatus Hagen (Odonata: Gomphidae), commonly called dusky clubtail, is a common and widely distributed dragonfly in a variety of ponds, lakes, and slow streams throughout its range in the north-eastern and northcentral United States ...
