Tracing the history of an unusual compound presolar grain from progenitor star to asteroid parent body host
Sheryl A. Singerling, Larry R. Nittler, Jens Barosch +3
We conducted a TEM study of an unusual oxide-silicate composite presolar grain (F2-8) from the unequilibrated ordinary chondrite Semarkona. The presolar composite grain is relative…
Presolar stardust in asteroid Ryugu
Jens Barosch, Larry R. Nittler, Jianhua Wang +121
We have conducted a NanoSIMS-based search for presolar material in samples recently returned from C-type asteroid Ryugu as part of JAXA's Hayabusa2 mission. We report the detection…
TEM analyses of in situ presolar grains from unequilibrated ordinary chondrite LL3.0 Semarkona
Sheryl A. Singerling, Larry R. Nittler, Jens Barosch +3
We investigated six presolar grains from very primitive regions of the matrix in the unequilibrated ordinary chondrite Semarkona with TEM. These grains include one SiC, one oxide (…
Room-temperature oxygen transport in nano-thin BixOySez enables precision modulation of 2D materials
Zachariah Hennighausen, Bethany M. Hudak, Madeleine Phillips +8
Oxygen conductors and transporters are important to several consequential renewable energy technologies, including fuel cells and syngas production. Separately, monolayer transitio…
Laser-patterned submicron Bi2Se3-WS2 pixels with tunable circular polarization at room temperature
Zachariah Hennighausen, Darshana Wickramaratne, Kathleen M. McCreary +7
Characterizing and manipulating the circular polarization of light is central to numerous emerging technologies, including spintronics and quantum computing. Separately, monolayer…
TEM analyses of unusual presolar silicon carbide: Insights into the range of circumstellar dust condensation conditions
Sheryl A. Singerling, Nan Liu, Larry R. Nittler +2
Presolar silicon carbide (SiC) grains in meteoritic samples can help constrain circumstellar condensation processes and conditions in C-rich stars and core-collapse supernovae. Thi…
