Processing of advanced Al/SiC particulate metal matrix composites under intensive shearing – A novel rheo process [PDF]

open access: yes, 2008
Particulate Metal Matrix Composites (PMMCs) have attracted interest for application in numerous fields. The current processing methods often produce agglomerated particles in the ductile matrix and as a result these composites exhibit extremely low ...

Effect of interfacial thermal mismatch on mechanical properties of metal matrix composites

open access: yesFenmo yejin jishu, 2023
The interfacial thermal mismatch stress will generate at the reinforcement/metal matrix heterogeneous interfaces during the cooling process of the metal matrix composites (MMCs), due to the large mismatch of the coefficient of thermal expansion (CTE ...

Active oxygen species mediate the iron-promoting electrocatalysis of oxygen evolution reaction on metal oxyhydroxides

open access: yesNature Communications, 2023
Iron is an extraordinary promoter to impose nickel/cobalt (hydr)oxides as the most active oxygen evolution reaction catalysts, whereas the synergistic effect is actively debated. Here, we unveil that active oxygen species mediate a strong electrochemical

Superflexible and Lead-Free Piezoelectric Nanogenerator as a Highly Sensitive Self-Powered Sensor for Human Motion Monitoring

open access: yesNano-Micro Letters, 2021
For traditional piezoelectric sensors based on poled ceramics, a low curie temperature (T c) is a fatal flaw due to the depolarization phenomenon. However, in this study, we find the low T c would be a benefit for flexible piezoelectric sensors because ...

Low-Temperature Soft-Cover-Assisted Hydrolysis Deposition of Large-Scale TiO2 Layer for Efficient Perovskite Solar Modules

open access: yesNano-Micro Letters, 2018
Perovskite solar cells with TiO2 electron transport layers exhibit power conversion efficiency (PCE) as high as 22.7% in single cells. However, the preparation process of the TiO2 layer is adopted by an unscalable method or requires high-temperature ...
