Toughening β‐Ga2O3 via Mechanically Seeded Dislocations
Advanced Functional Materials, EarlyView.β‐Ga2O3 is promising for next‐generation semiconductors but its brittleness limits flexible and high‐precision applications. Here, mechanically seeded dislocations introduced by surface deformation improved damage tolerance in (001) β‐Ga2O3. Nanoindentation and characterization show dislocations suppress cleavage cracks by enabling stable plastic ...

Near-field sonic-boom pressure signatures for the space shuttle launch and orbiter vehicles at Mach 6 [PDF]
Static-pressure signatures parallel to the flight path of the launch and entry configurations of the space shuttle were measured. The launch configurations, consisting of an equivalent body of revolution (representing the orbiter and external fuel tank ...

Geometry‐Dependent Adhesion in Transparent Monodomain Liquid Crystal Elastomers
Advanced Functional Materials, EarlyView.Liquid Crystal Elastomers (LCEs) are emerging as exciting pressure‐sensitive adhesives. We examine adhesion in chemically identical elastomer films, exploring the influence of geometry (director orientation) and phase (nematic or isotropic). We demonstrate the potential of these aligned films as transparent, tunable, broad‐temperature‐range smart ...

Control of Polarization and Polar Helicity in BiFeO3 by Epitaxial Strain and Interfacial Chemistry
Advanced Functional Materials, EarlyView.In BiFeO3 thin films, the interplay of interfacial chemistry, electrostatics, and epitaxial strain is engineered to stabilize homohelicity in polarization textures at the domain scale. The synergistic use of a Bi2O2‐terminated Aurivillius buffer layer and a highly anisotropic compressive epitaxial strain offers new routes to control the polar‐texture ...

Longitudinal control effectiveness and entry dynamics of a single-stage-to-orbit vehicle [PDF]
The classical theory of flight dynamics for airplane longitudinal stability and control analysis was extended to the case of a hypervelocity reentry vehicle. This includes the elements inherent in supersonic and hypersonic flight such as the influence of
