In-Orbit Aerodynamic Coefficient Measurements using SOAR (Satellite for Orbital Aerodynamics Research)
N. H. Crisp, P. C. E. Roberts, S. Livadiotti +26
The Satellite for Orbital Aerodynamics Research (SOAR) is a CubeSat mission, due to be launched in 2021, to investigate the interaction between different materials and the atmosphe…
A Review of Gas-Surface Interaction Models for Orbital Aerodynamics Applications
Sabrina Livadiotti, Nicholas H. Crisp, Peter C. E. Roberts +29
Renewed interest in Very Low Earth Orbits (VLEO) - i.e. altitudes below 450 km - has led to an increased demand for accurate environment characterisation and aerodynamic force pred…
Atomic Resolution Imaging of CrBr using Adhesion-Enhanced Grids
Matthew J. Hamer, David G. Hopkinson, Nick Clark +7
Suspended specimens of 2D crystals and their heterostructures are required for a range of studies including transmission electron microscopy (TEM), optical transmission experiments…
Holographic reconstruction of the interlayer distance of bilayer two-dimensional crystal samples from their convergent beam electron diffraction patterns
Tatiana Latychevskaia, Yichao Zou, Colin Robert Woods +5
The convergent beam electron diffraction (CBED) patterns of twisted bilayer samples exhibit interference patterns in their CBED spots. Such interference patterns can be treated as…
The Benefits of Very Low Earth Orbit for Earth Observation Missions
N. H. Crisp, P. C. E. Roberts, S. Livadiotti +30
Very low Earth orbits (VLEO), typically classified as orbits below approximately 450 km in altitude, have the potential to provide significant benefits to spacecraft over those tha…
Raman Fingerprints of Graphene Produced by Anodic Electrochemical Exfoliation
Vaiva Nagyte, Daniel J. Kelly, Alexandre Felten +11
Electrochemical exfoliation is one of the most promising methods for scalable production of graphene. However, limited understanding of its Raman spectrum as well as lack of measur…
Graphene-TiS heterojunction for selective polar vapor sensing at room temperature
Nassim Rafiefard, Azam Iraji zad, Ali Esfandiar +5
In this work, the room temperature polar vapor sensing behavior of two dimentional (2D) heterojunction Graphene-TiS3 materials and TiS3 nanoribbons is investigated. TiS3 nanoribbon…
Design-controlled Synthesis of IrO sub-monolayers on Au Nanodendrites: Marrying Plasmonic and Electrocatalytic Properties
Isabel C. de Freitas, Luanna S. Parreira, Eduardo C. M. Barbosa +10
We develop herein plasmonic-catalytic Au-IrO nanostructures with a morphology optimized for efficient light harvesting and catalytic surface area; the nanoparticles have a dend…
Convergent beam electron diffraction of multilayer van der Waals structures
Tatiana Latychevskaia, Colin Robert Woods, Yi Bo Wang +4
Convergent beam electron diffraction is routinely applied for studying deformation and local strain in thick crystals by matching the crystal structure to the observed intensity di…
