Triassic in the eastern Sichuan basin ray slope and badong group strata division and correlation [PDF]
E3S Web of Conferences, 2022 Triassic strata are widely developed in the eastern part of Sichuan Basin. The Mingyuexia anticline and Huangnitang anticline located in the eastern Sichuan structural belt develop Triassic Jialingjiang Formation to Xujiahe Formation. The middle Triassic

The three phases of galaxy formation [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 We investigate the origin of the Hubble sequence by analysing the evolution of the kinematic morphologies of central galaxies in the EAGLE cosmological simulation. By separating each galaxy into disk and spheroidal stellar components and tracing their evolution along the merger tree, we find that the morphology of galaxies follows a common evolutionary

Phase formation in magnetron sputtered CrMnFeCoNi high entropy alloy
, 2020 Thin films of the CrMnFeCoNi high entropy alloy were deposited by magnetron sputtering from a sintered equimolar target. The substrate temperature and bias were varied during deposition, and the structure, morphology and elemental distribution were ...

Microstructures in phase-inversion membranes. Part I. Formation of macrovoids [PDF]
, 1992 A new mechanism for the formation of macrovoids in phase-inversion membranes is proposed. It is based on the observed difference in type of demixing of a thin film of a polymer solution when immersed in a nonsolvent bath: delayed or instantaneous ...

The Genealogical Tree of Ethanol: Gas-phase Formation of Glycolaldehyde, Acetic Acid, and Formic Acid [PDF]
, 2017 Despite the harsh conditions of the interstellar medium, chemistry thrives in it, especially in star-forming regions where several interstellar complex organic molecules (iCOMs) have been detected. Yet, how these species are synthesized is a mystery. The

ANALYSIS OF Nb – Ni AND V – Ni BASED MEMBRANE CHARACTERISTICS
Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2021 To obtain ultrapure hydrogen by membrane technology, instead of expensive membranes made of Pd alloys, cheaper ones based on metals (Nb-Ni) and (V-Ni) are considered.
