AP Librae: The Extended Jet as the Source of VHE Emission?
Galaxies, 2016 The LBL AP Librae has been detected in the TeV gamma-ray range, which is unexpected for this kind of blazar. The broad-band SED cannot be explained by a one-zone model, and especially fails in the TeV domain.

In Situ Micromechanical Study of Bimodal γ′–γ″ Precipitate Assemblies in Ni–Cr–Al–Nb Superalloy
Advanced Engineering Materials, EarlyView.A Ni–Cr–Al–Nb superalloy with a bimodal γ′–γ″ precipitate distribution is developed. Composite precipitate assemblies form through heterogeneous nucleation, effectively impeding dislocation motion. Micropillar compression reveals high strength at room and elevated temperatures, governed by precipitate shearing, with coupled faulting mechanisms ...

An extraordinary view of the universe: The use of X-ray vision in space science
Mètode Science Studies Journal: Annual Review, 2017 X-ray emission from cosmic sources indicates that these sources are heated to temperatures exceeding a million degrees or that they contain highly energetic particles.

Advanced Engineering Materials, EarlyView.Composite Ti–6Al–4V–epoxy lattice structures are additively manufactured and epoxy infiltrated for cyclic loading. At low lattice volume fractions, hybridization produces synergistic gains in stiffness and energy dissipation. At higher volume fractions, synergy diminishes, although composites still exceed metallic lattices in specific energy ...

Time-Mean Helicity Distribution in Turbulent Swirling Jets
Acta Polytechnica, 2005 Helicity offers an alternative approach to investigations of the structure of turbulent flows. Knowledge of the spatial distribution of the time-mean component of helicity is the starting point.

Advanced Engineering Materials, EarlyView.This work shows that the mechanical performance of multimaterial digital light processing (DLP) printed thermoset composites is governed by resin compatibility and interfacial design rather than spatial patterning alone. Brittle and ductile resin combinations produced premature interfacial failure, while graded interfaces and mechanically compatible ...

Turbulence modelling of turbulent buoyant jets and compartment fires [PDF]
, 2001 Turbulent buoyant jets are a major feature in fire hazards. The solution of the Reynolds Averaged Navier-Stokes (RANS) equations through computational fluid dynamic (CFD) techniques allow such flows to be simulated.

Feasibility of Nitrogen as a Carrier Gas for Inconel Cold Spray in Hydropower Application
Advanced Engineering Materials, EarlyView.N2, despite being nearly two orders of magnitude cheaper than He, is a feasible carrier gas for cold spray Inconel coatings in hydropower repair applications when higher gas temperature and pressure are used. Reducing powder size significantly improved cavitation resistance, while the addition of fine chromium carbide particles further enhanced erosion
