Exploring Microstructure–Physical Property–Corrosion Response Relationship in Intermetallic Compounds of Al‐Cu Bimetallic Interfaces

Advanced Engineering Materials, EarlyView.
Al‐Cu intermetallic compounds (IMCs) have a significant influence on the properties of Al‐Cu bimetallic interfaces formed in compound casting. This article provides a deeper understanding of microstructure, crystallography, thermal properties, hardness, and corrosion response of Al‐Cu IMCs with the goal of facilitating the optimization of the ...

The Extraordinary `Superthin' Spiral Galaxy UGC7321. I. Disk Color Gradients and Global Properties from Multiwavelength Observations

, 1999
We present B- and R-band imaging and photometry, H-alpha narrow-band imaging, NIR H-band imaging, and HI 21-cm spectroscopy of the nearby Sd spiral galaxy UGC7321. UGC7321 exhibits a remarkably thin stellar disk with no bulge component.

X‐Ray Tomography Analysis of Damage Mechanisms in Metal Matrix Syntactic Foams During Compression

Advanced Engineering Materials, EarlyView.
In situ synchrotron X‐ray tomography is used to investigate the internal damage mechanisms of AlSi12 metal matrix syntactic foam with ceramic hollow spheres during compressive loading. It is concluded that a homogeneous distribution of the second‐phase filler material results in a sequential collapse in a localized region; this leads to controlled and ...

Broadband subwavelength imaging of flexural elastic waves in flat phononic crystal lenses

Scientific Reports, 2023
Subwavelength imaging of elastic/acoustic waves using phononic crystals (PCs) is limited to a narrow frequency range via the two existing mechanisms that utilize either the intense Bragg scattering in the first phonon band or negative effective ...

Trace Nickel Activated Biphasic Core‐CuOii/Shell‐CuOi Secondary Microspheres Enable Room Temperature Parts‐Per‐Trillion‐Level NO2 Detection

Advanced Engineering Materials, EarlyView.
An idea of designing novel sensors is proposed by creating appropriate Schottky barriers and vacancies between isomorphous Core‐CuOii/ Shell‐CuOi secondary microspheres and enhancing catalytic and spill‐over effects, and electronegativity via spontaneous biphasic separation, self‐assembly, and trace‐Ni‐doping.

Solutions of several theory and technique problems in high-space-resolving hotspot electron temperature diagnosis techniques in inertial confinement fusion

AIP Advances, 2022
In implosion experiments, bremsstrahlung radiation ratios of broad-energy-band x-ray emission intensities (sampled by Ross pair) and narrow-energy-band x-ray emission intensities (sampled by multilayer) are typically used to extract the hotspot electron ...

Colour analysis of degraded parchment [PDF]

, 2013
Multispectral imaging was employed to collect data on the degradation of an 18th century parchment by a series of physical and chemical treatments. Each sample was photographed before and after treatment by a monochrome digital camera with 21 narrow-band

Interactions between Molten High‐Silicon Electrical Steels and Carbon‐Bonded MgO Refractories Based on Recyclates

Advanced Engineering Materials, EarlyView.
This study examines how several molten high‐silicon electrical steels interact with both conventional and recycled MgO–C refractories. For this, various immersion experiments are conducted. In addition to infiltration, a number of mechanisms are identified and explained that control the corrosion of the refractory material.
