Autor: Ezat Heydari, Jeffrey F. Schroeder, Fred J. Calef, Timothy J. Parker, Alberto G. Fairén

Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-24 (2023)

Abstract This investigation documents that the Rugged Terrain Unit, the Stimson formation, and the Greenheugh sandstone were deposited in a 1200 m-deep lake that formed after the emergence of Mt. Sharp in Gale crater, Mars, nearly 4 billion years ago

International audience; The lowermost exposure of the Murray formation in Gale crater, Mars, was interpreted as sediment deposited in an ancient lake based on data collected by the Curiosity rover. Constraining the stratigraphic extent and duration o

This study reports in-situ sedimentologic evidence of giant floods in Gale crater, Mars, during the Noachian Period. Features indicative of floods are a series of symmetrical, 10 m-high gravel ridges that occur in the Hummocky Plains Unit (HPU). Thei

Luminescence properties of CaWO4 and CaWO4:Eu3+ nanostructures prepared at low temperature

Autor: Mehri Fadavi, Ying Zhang, Tigran V. Shahbazyan, Ezat Heydari, Aman Abraha, Rong Zhang, Qilin Dai

Publikováno v: Optical Materials. 84:115-122

The synthesis of luminescence nanostructures is always related with complicated procedures, and it is still challenging to control their luminescence properties by a facile method. In this work, CaWO4:Eu3+ nanostructures with different morphology, st
