Obliquity Dependence of Ocean Productivity and Atmospheric CO2 on Earth-like Worlds
Published 2025-01-01“…In this study, we investigate the effects of obliquity on ocean NPP and the atmospheric CO _2 concentration using ROCKE-3D fully coupled to the NASA GISS Ocean Biogeochemistry Model. We find sea surface temperature primarily controls the NPP response, with both properties reaching a maximum at an obliquity of 45°. …”

High-Electron-Mobility SiGe on Sapphire Substrate for Fast Chipsets
Published 2015-01-01“…Therefore, radio frequency devices which are made with rhombohedral SiGe on c-plane sapphire can potentially run a few times faster than RF devices on SOS wafers. NASA Langley has successfully grown highly ordered single crystal rhombohedral epitaxy using an atomic alignment of the [111] direction of cubic SiGe on top of the [0001] direction of the sapphire basal plane. …”

Engineering Application of an Identification Method to Shock-Induced Vortex Stability in the Transonic Axial Fan Rotor
Published 2021-01-01“…In the present paper, the steady RANS (Reynolds-Averaged Navier-Stokes) simulations based on our independently developed CFD (Computational Fluid Dynamics) solver NUAA-Turbo 2.0, are carried out to investigate the shock wave/tip leakage vortex (SW/TLV) interaction in two representative transonic axial fan rotors, NASA Rotor 67 and NASA Rotor 37. The intent of this study is mainly to verify if an identification method derived from relevant theories is suitable for shock-induced vortex stability in the real engineering environment. …”
