Materials Data on TaSiAs by Materials Project

TaSiAs is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Ta5+ is bonded in a 9-coordinate geometry to four equivalent Si4- and five equivalent As1- atoms. All Ta–Si bond lengths are 2.67 Å. There are four shorter (2.70 Å) and one longer (2.85 Å) Ta–As bond lengths. Si4- is bonded in a 8-coordinate geometry to four equivalent Ta5+ and four equivalent Si4- atoms. All Si–Si bond lengths are 2.49 Å. As1- is bonded in a 5-coordinate geometry to five equivalent Ta5+ atoms.

Leveraging national laboratories to increase Black representation in STEM: recommendations within the Department of Energy

Increasing diversity in STEM disciplines has been a goal at scientific institutions for many decades. Black representation in STEM, however, has remained critically low at all levels (high school, undergraduate, graduate, and professional) for over 40 years, highlighting the need for innovative strategies that promote and retain Black students and professionals in STEM. We refocus efforts on increasing Black representation in STEM by promoting early exposure and continued engagement while leveraging national laboratories—an underutilized resource with immense potential to centralize diversity and inclusion efforts nationally.
