Advanced Engineering Materials, EarlyView.A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.

Lung diffusing capacity for nitric oxide in space: microgravity gas density interactions
Frontiers in Physiology, 2023 Introduction: During manned space exploration lung health is threatened by toxic planetary dust and radiation. Thus, tests such as lung diffusing capacity (DL) are likely be used in planetary habitats to monitor lung health. During a DL maneuver the rate

Generalized Wick transform in dimensionally reduced gravity [PDF]
Classical and Quantum Gravity, 2003 In the context of canonical quantum gravity, we study an alternative real quantisation scheme, which is arising by relating simpler Riemannian quantum theory to the more complicated physical Lorentzian theory - the generalised Wick transform. On the symmetry reduced models, homogenous Bianchi cosmology and 2+1 gravity, we investigate its generalised ...

Combustion of Methanol Droplets in Air-Diluent Environments with Reduced and Normal Gravity
Journal of Combustion, 2012 Reduced and normal gravity combustion experiments were performed with fiber-supported methanol droplets with initial diameters in the 1 mm size range. Experiments were performed with air-diluent mixtures at about 0.101 MPa and 298 K, where carbon dioxide,

Stretching the Printability Metric in Direct‐Ink Writing with Highly Extensible Yield‐Stress Fluids
Advanced Functional Materials, EarlyView.This study introduces “drawability” as a new metric for assessing printability in direct‐ink writing, focusing on gap‐spanning performance and speed robustness. By designing yield‐stress fluids with high extensibility, we demonstrate that extensional strain‐to‐break significantly enhances printability.

Crustal structure of the spreading plate boundary in Iceland and the north Atlantic from gravity data [PDF]
, 1994 Gravity datasets from two geothermal areas in Iceland, an Iceland-wide gravity dataset, and marine gravity data from the Reykjanes Ridge at 58˚N, which can be seen as the submarine extension of the Icelandic accretionary system, have been studied in this
