High-Resolution Chronological Refinement, Titanium Intensity and Flux Implications
Published on 2025-03-10 by Mianjin Chen, Xiao Sun, Yang Li, Yulong Xue, Wenzhe Lyu, Xuemu Wang, Yan Li @MDPI
Abstract: Episodic sedimentary processes with significant changes in sedimentation rate have occurred on the East Hainan Coast, the inner shelf of the South China Sea, since the Last Glacial Maximum. In particular, the early-Holocene (~11.5–8.7 ka) rapid sedimentation at a mean rate of ~4.90 m/ka is crucial to understand the processes of terrigenous input to the ocean, carbon cycling and climate control in coastal-neritic sedimentary evolution. However, the chronological framework and the de[...]
Our summary: High-resolution chronological refinement of sedimentary processes on the East Hainan Coast during the early-Holocene period reveals significant changes in sedimentation rate and terrigenous input. The study utilizes luminescence signals and XRF scanning to refine the chronological framework and understand the compound controls of global ice-volume change, monsoon dynamics, and coastal geomorphic evolution on sedimentary processes.

Abstract: To meet the application requirements for structural components in Gen-IV nuclear reactors, it is essential to improve the high-temperature mechanical properties of 25Ni-20Cr (S35140) austenitic stainless steel. In this research, an improved austenitic stainless steel (N-S35140), derived from S35140 steel, was investigated. The scanning transmission electron microscopy (STEM) results indicate that the addition of titanium (Ti) microalloying elements to S35140 steel led to the precipitation of new[...]
Our summary: Improved austenitic stainless steel (N-S35140) with titanium microalloying elements shows enhanced mechanical properties, including higher tensile strength and elongation, making it a promising candidate for structural components in Gen-IV nuclear reactors.
