SYNCHROTRON POLARIZATION IN BLAZARS [PDF]

open access: yesThe Astrophysical Journal, 2014
We present a detailed analysis of time- and energy-dependent synchrotron polarization signatures in a shock-in-jet model for gamma-ray blazars. Our calculations employ a full 3D radiation transfer code, assuming a helical magnetic field throughout the jet.

Micromechanical behaviors related to confined deformation in pure titanium [PDF]

open access: yesMATEC Web of Conferences, 2020
Confined deformation, e.g. mechanical twinning, shear banding, and Lüders banding, etc. was extensively observed in metals and alloys with low stacking-fault energies, especially under complex loadings, governing the mechanical properties.

Fixed-Target Pink-Beam Serial Synchrotron Crystallography at Pohang Light Source II

open access: yesCrystals, 2023
Serial crystallography (SX) enables the determination of the structure of macromolecules or small molecules with minimal radiation damage. In particular, biomolecule structures determined using the SX technique have the advantage of providing room ...

On the Effect of Heat Input and Interpass Temperature on the Performance of Inconel 625 Alloy Deposited Using Wire Arc Additive Manufacturing–Cold Metal Transfer Process

open access: yesMetals, 2021
Relatively high heat input and heat accumulation are treated as critical challenges to affect the qualities and performances of components fabricated by wire arc additive manufacturing (WAAM). In this study, various heat inputs, namely 276, 552 and 828 J/

Retrieving Tarnished Daguerreotype Content Using X-ray Fluorescence Imaging—Recent Observations on the Effect of Chemical and Electrochemical Cleaning Methods

open access: yesHeritage, 2021
We report a study on the effect of chemical and electrochemical cleaning of tarnished daguerreotypes observed using X-ray fluorescence (XRF) microscopy with a micro-focussed X-ray beam from a synchrotron source.

Investigate the Function and Structure of (Fe,Cr) La2Ti2O7 Photocatalyst Calcined under the Nitrogen Atmosphere

open access: yesBulletin of Chemical Reaction Engineering & Catalysis, 2023
Extensive research has been conducted on enhancing the photocatalytic activity of Lanthanum titanium oxide (La2Ti2O7) based photocatalysts. However, these photocatalysts were found to be inactive under visible light.

Synchrotron X-ray Analysis of the Influence of the Magnesium Content on the Absorptance during Full-Penetration Laser Welding of Aluminum

open access: yesMetals, 2021
Full-penetration laser beam welding is characterized by a weld seam whose depth equals the material thickness. It is associated with a stable capillary and is therefore widely used for welding of sheet metal components.

Noncommutative synchrotron [PDF]

open access: yesPhysical Review D, 2004
We study the departures from the classical synchrotron radiation due to noncommutativity of coordinates. We find that these departures are significant, but do not give tight bounds on the magnitude of the noncommutative parameter. On the other hand, these results could be used in future investigations in this direction. We also find an acausal behavior
