This month, in honor of Black History Month, we wanted to highlight 17 Black chemists you might have missed in class:
Winifred Burks-Houck was an environmental organic chemist and the first woman president of @NOBCChE. During her work at @Livermore_Lab she minimized threats to worker safety and limited the lab’s environmental impact. Learn more about her at ow.ly/UEyh50DnQEo #BlackInSTEM
Charles Drew, better known as the father of the blood bank, found that blood could be preserved longer once the plasma and the red blood cells were separated. A well-timed finding, since WWII was breaking out in Europe. Read more about Drew at ow.ly/CB5e50DnQOL #BlackInSTEM

C'est toujours sympa d'avoir des molécules animés dans un cours ...😀 sous forme de gif animé par exemple

Et c'est en fait très rapide à faire ... à peine quelques minutes !

C'est parti pour un rapide tuto

#Teamphys #chemEd #chemAnim
Pour réaliser ces gif animés il suffit de 2 logiciels libres :
@AvogadroChem : avogadro.cc qui permet de dessiner les molécules (mais pas seulement d'ailleurs !)⚛️

@GetShareX : getsharex.com qui est un outil de capture d'écran très très complet 🖥️
@AvogadroChem @GetShareX Après installation de ces deux logiciels, il faut lancer shareX puis Avogadro.

Dans Avogadro vous pouvez créer la molécule...
... ou vous pouvez vous contenter de taper son nom
menu File - Import - Fetch by chemical name ... et dans la boite de dialogue taper le nom et voilà 😍
