X-Ray and Gamma-Ray Polarization in Leptonic and Hadronic Jet Models of Blazars

open access: yes, 2013
We present a theoretical analysis of the expected X-ray and gamma-ray polarization signatures resulting from synchrotron self-Compton emission in leptonic models, compared to the polarization signatures from proton synchrotron and cascade synchrotron ...

The synchrotron peak shift during high-energy flares of blazars [PDF]

open access: yes, 1999
A prediction for the energy shift of the synchrotron spectrum of flat-spectrum radio quasars (FSRQs) during high-energy flares is presented. If the $\gamma$-ray emission of FSRQs is produced by Comptonization of external radiation, then the peak of the ...

Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

open access: yesAdvanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Quantitative Analysis of Slow-extraction Spill Spectrum and Its Application

open access: yesYuanzineng kexue jishu, 2022
Slow extraction from synchrotrons is widely used for delivering hadron beams to many physical experiments as well as hadron cancer therapy based on charged particle deposition on tumors. The extracted beam is also referred to as spill.

Understanding and Optimizing Li Substitution in P2‐Type Sodium Layered Oxides for Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous

A Computed Microtomography Method for Understanding Epiphyseal Growth Plate Fusion

open access: yesFrontiers in Materials, 2018
The epiphyseal growth plate is a developmental region responsible for linear bone growth, in which chondrocytes undertake a tightly regulated series of biological processes. Concomitant with the cessation of growth and sexual maturation, the human growth

Regional diversity in the murine cortical vascular network is revealed by synchrotron X-ray tomography and is amplified with age [PDF]

open access: yesEuropean Cells & Materials, 2018
Cortical bone is permeated by a system of pores, occupied by the blood supply and osteocytes. With ageing, bone mass reduction and disruption of the microstructure are associated with reduced vascular supply.
