Cu–Ni–Sn–Si alloys designed by cluster-plus-glue-atom model

Materials & Design, 2019
Segregation in the solidification process and discontinuous precipitation during aging cause the service and processing performance of Cu–Ni–Sn alloys deteriorating severely.

Characterization of helium retention in the inhomogeneous co-deposited layers using a long pulse laser induced ablation-quadrupole mass spectroscopy

Nuclear Materials and Energy, 2022
In this work, a spatially lateral-resolved study of the co-deposition of helium (He) and aluminum (Al) in non-uniform layers is carried out by a long pulse Laser-Induced Ablation-Quadrupole Mass Spectrometry (LIA-QMS) approach.

Rational design of 2D organic magnets with giant magnetic anisotropy based on two-coordinate 5d transition metals

APL Materials, 2020
As a new class of single-molecule magnets, two-coordinate complexes of open-shell transition metals are comparatively rare and have attracted interest due to their high degree of coordinative unsaturation.

Observation of the significant reductions of electron density and electron temperature in a cascaded arc high density argon plasma with ammonia seeding comparing with nitrogen seeding by laser Thomson scattering approach

Nuclear Materials and Energy, 2022
In this work, the influences of ammonia (NH3) seeding on the electron density (ne) and electron temperature (Te) in a high-density cascaded arc argon plasma have been investigated by laser Thomson scattering. As NH3 seeding ratio increases from 0% to 2%,

Atomic laser-beam finder

Optics Express, 2012
We report on an experimental method to align a laser beam to a cloud of atoms trapped in a magneto-optical trap (MOT). We show how balanced lock-in detection leads to a very sensitive method to align the laser beam to the atoms in the plane perpendicular to the propagation direction. This provides a very reliable and fast way of aligning laser beams to

Laser-PIXE using laser-accelerated proton beams [PDF]

Scientific Reports, 2019
AbstractLaser-driven proton acceleration is a field of growing interest, in particular for its numerous applications, including in the field of materials science. A benefit of these laser-based particle sources is their potential for a relative compactness in addition to some characteristics at the source that differ from those of conventional, radio ...

Temperature and energy effects on secondary electron emission from SiC ceramics induced by Xe17+ ions

Scientific Reports, 2017
Secondary electron emission yield from the surface of SiC ceramics induced by Xe17+ ions has been measured as a function of target temperature and incident energy. In the temperature range of 463–659 K, the total yield gradually decreases with increasing

New fine structure of red luminescence in ZnO observed under exciton resonance excitation

AIP Advances, 2019
A new fine structure of red luminescence (RL) was observed in unintentionally doped ZnO at low temperature. The new RL was demonstrated to be different from the one assigned to Fe3+ center by Heitz et al and visible only under the excitation of light ...
