Strain Localization Along Aphrodite Terra's Chasmata System, Venus: The Role of Frictional Melting and Fault‐Melt Interaction

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.
Abstract We analyze large‐scale shear zones that are exposed along the equatorial chasmata of Eastern Aphrodite Terra to understand the role of strain localization in the deformation of the Venusian crust. These shear zones dip at low angles opposite to the slopes, forming terraces that expose portions of the shear planes.

Effect of Si content on low-temperature superplasticity in Fe–10Mn steel

open access: yesJournal of Materials Research and Technology
We systematically investigated the effect of Si on the low-temperature superplasticity of 50% and 80% cold-rolled Fe–10Mn-(0.2–5.5)Si steels through tensile testing at 763 K with strain rates of 1 × 10−3 s−1 and 1 × 10−4 s−1. Superplasticity was achieved

Effect of Heating Rate on Grain Structure and Superplasticity of 7B04 Aluminum Alloy Sheets

open access: yesCailiao gongcheng, 2017
Fine-grained 7B04 aluminum alloy sheets were manufactured through thermo-mechanical treatment. The effects of anneal heating rate on grain structure and superplasticity were investigated using electron back scattering diffraction(EBSD) and high ...

Analysis of the failure mechanism of ZnO varistors influenced by high‐resistance media based on multi‐field coupling simulation

open access: yesHigh Voltage, Volume 10, Issue 3, Page 673-679, June 2025.
Abstract This study focuses on the distribution of high‐resistance media (pores and spinels) within ZnO $\text{ZnO}$ varistors and explores the mechanical and electrical failure mechanisms of varistors under different pulse actions. Micro‐CT technology revealed that the proportion of high‐resistance media in the edge area is much higher than in the ...

One‐Pot Synthesis and Characterization of Magnetic α‐Fe2O3/CuO/CuFe2O4 Nanocomposite for Multifunctional Therapeutic Applications

open access: yesChemistryOpen, Volume 14, Issue 2, February 2025.
This article presents the sol‐gel auto combustion synthesis of α‐Fe2O3/CuO/CuFe2O4 using Centella Asiatica plant extract as a green precursor. Significant antifungal and antioxidant properties were shown by this compound. This nanocomposite also investigated as a drug nanocarrier at different pH levels and compared by fitting the data to various drug ...
