Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics

open access: yesAdvanced Materials, EarlyView.
Bi doped metallic Cu nanowires are promising for spintronics thanks to the stabilization of a giant spin Hall effect. However, heat resulting from current injection forces Bi to leave solution, forcing segregation into monoatomic decorations which evolve into coherent crystalline aggregates.

On the spectrum of moderated neutrons emitted by the isotropic source in the gas fuel

open access: yesЯдерна фізика та енергетика, 2016
Analytical formula for the equation of the neutron scattering for isotropic neutron source, which includes the temperature of the moderating medium as the parameter, was first obtained in the given work in the framework of gas model of the medium.

Fukushima plutonium effect and blow-up regimes in neutron-multiplying media

open access: yes, 2013
It is shown that the capture and fission cross-sections of 238U and 239Pu increase with temperature within 1000-3000 K range, in contrast to those of 235U, that under certain conditions may lead to the so-called blow-up modes, stimulating the anomalous ...

Temperature Coefficient of Neutron Multiplication Factor [PDF]

open access: yesJournal of Nuclear Science and Technology, 1964
A method for calculating the temperature coefficient of the neutron multiplication factor in an infinite homogeneous medium is investigated for the purpose of discussion of the temperature coefficient for thermal reactors. Two kinds of expression for the temperature coefficient of the neutron multiplication factor are derived and given in terms of ...

Coupling Nanostructured Plasmon–Strain Microwave Waveguide to Spin Defects in Hexagonal Boron Nitride for High‐Sensitivity Quantum Sensors

open access: yesAdvanced Materials, EarlyView.
Coupling of spin‐active VB−$V_B^ - $ defects in hBN with alumina‐coated gold plasmonic nanoresonators (PNRs), integrated into a microwave‐efficient waveguide, constitutes a plasmon‐strain architecture that enhances their photoluminescence and spin contrast. This platform enables a tenfold quantum yield improvement and achieves a DC magnetic sensitivity

Cooling of Accretion-Heated Neutron Stars

open access: yes, 2017
We present a brief, observational review about the study of the cooling behaviour of accretion-heated neutron stars and the inferences about the neutron-star crust and core that have been obtained from these studies.

Resolving Complex Multiscale Structure of Magneto‐ and Electroactive Polymer Composites With an Ionic Liquid

open access: yesAdvanced Materials, EarlyView.
Multiscale ionic liquid segregation into nano‐sized domains in the unconfined amorphous polymer phase and into micron‐sized pores enables a coupled magneto‐ and electroactive responses. ABSTRACT A multiscale understanding of the structure of ionogels – nanoparticle‐free polymer composites incorporating ionic liquids – is essential for enhancing their ...

Effect of Neutron Fluence Rate on Irradiation Embrittlement of Low-copper RPV Steel

open access: yesYuanzineng kexue jishu
The reactor pressure vessels (RPVs) of pressurized water reactor (PWR) nuclear power plants currently in operation and under construction in China are all made of low-alloy ferritic steels obtained by quenching and tempering treatments (which meet the ...

Beyond Earth: Resilience of Quasi‐2D Perovskite Solar Cells in Space

open access: yesAdvanced Materials, EarlyView.
In the article (DOI: 10.1002/adma.202520433), Christoph Putz and co‐workers demonstrate rigid quasi‐2D perovskite solar cells operating in low Earth orbit, delivering stable power for more than 100 days under real‐space conditions. In‐orbit performance is correlated with extensive ground‐based thermal and proton‐irradiation studies on rigid and ...
