A multiple-impact origin for the Moon [PDF]

open access: yes, 2017
The hypothesis of lunar origin by a single giant impact can explain some aspects of the Earth–Moon system. However, it is difficult to reconcile giant-impact models with the compositional similarity of the Earth and Moon without violating angular ...

Micro moon versus macro moon: Brightness and size [PDF]

open access: yesarXiv, 2015
The moon, moonlight, phases of the moon and its relatively simple recurring cycle has been of interest since time immemorial to the human beings, navigators, astronomers and astrologers. The fact that its orbit is elliptical as well its plane is inclined with the plane of rotation of the earth gives rise to new moon to full moon and solar and lunar ...

Comparative Evaluation of HFC‐134a Decompositions Over Metal‐Impregnated γ‐Al2O3 Catalysts (M/γ‐Al2O3) (M = Mg, Ni, Co, Zn, Cu)

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This study examines the impact of an impregnated metalon the structural alterations of the catalyst induced by intermediatesgenerated during the HFC‐134a catalytic decomposition reaction. Through adetailed analysis of the catalyst before and after the reaction, the underlyingcause of the observed inactivity is elucidated.
