Etching of elemental layers in oxide molecular beam epitaxy by O2-assisted formation and evaporation of their volatile suboxide: The examples of Ga and Ge [PDF]
J. Vac. Sci. Technol. A 42, 032708 (2024)The delivery of an elemental cation flux to the substrate surface in the oxide molecular beam epitaxy (MBE) chamber has been utilized not only for the epitaxial growth of oxide thin films in the presence of oxygen but also in the absence of oxygen for the growth temperature calibration (by determining the adsorption temperature of the elements) and in ...

Understanding the Impact of Synchronous, Asynchronous, and Hybrid In-Situ Techniques in Computational Fluid Dynamics Applications [PDF]
High-Performance Computing (HPC) systems provide input/output (IO) performance growing relatively slowly compared to peak computational performance and have limited storage capacity. Computational Fluid Dynamics (CFD) applications aiming to leverage the full power of Exascale HPC systems, such as the solver Nek5000, will generate massive data for ...

Crystallization via tubing microfluidics permits both in situ and ex situ X-ray diffraction [PDF]
arXiv, 2017 We used a microfluidic platform to address the problems of obtaining diffraction quality crystals and crystal handling during transfer to the X-ray diffractometer. We optimize crystallization conditions of a pharmaceutical protein and collect X-ray data both in situ and ex situ.

Tracing the cosmological origin of gas that fuels in situ star formation in TNG50 galaxies [PDF]
Based on their cosmological origin, the stars of a galaxy can be divided into two categories: those that enter through merger events (ex situ) and those born in the main progenitor (in situ). We used the TNG50 cosmological magnetohydrodynamical simulation and its Lagrangian tracer particles to explore and quantify the origin of gas that ultimately ...

In Situ Cryomodule Demagnetization [PDF]
arXiv, 2015 The feasibility of in-situ demagnetization of fully assembled superconducting RF cryomodules is demonstrated. Useful parametric values for demagnetization as well as measured effects on sensitive components within the cryomodule are listed and discussed.
