In-situ Non-destructive Determination of Major and Trace Elements in Large Size Ceramic Samples by Open Laser Ablation Inductively Coupled Plasma-Mass Spectrometry

Yankuang ceshi, 2021
BACKGROUND Usually, laser ablation inductively coupled plasma-mass spectrometry (LA-ICP-MS) analysis is equipped with a closed ablation cell. It cannot be used for non-destructive analysis of the large-size samples which exceeds the size of the cell ...

A Practical Noise2Noise Denoising Pipeline for High‐Throughput Raman Spectroscopy

Advanced Engineering Materials, EarlyView.
A lightweight and reproducible denoising pipeline for high‐throughput Raman spectroscopy is introduced, based on a 1D convolutional autoencoder trained with a Noise2Noise strategy. Using only repeated short‐exposure acquisitions, the method suppresses stochastic noise without reference spectra, enabling reliable spectral reconstruction while preserving

Intracrystalline Void‐Mediated Toughening of Brittle Crystals in Quail Eggshells

Advanced Functional Materials, EarlyView.
In quail eggshells, the high density and disordered arrangement of intracrystalline voids inhibit lattice cleavage, suppress long‐range crack propagation, and promote deformation twinning and quasi‐plasticity, serving as an essential toughening motif. We show that these voids remain within a narrow subcritical size range and therefore predominantly do ...

Geochemical cycling of arsenic in magmatic systems across supercontinent cycles

Scientific Reports
Arsenic (As) cycling in magmatic systems is influenced by tectonic and magmatic processes, yet its long-term behavior is not well understood. This study uses global whole-rock geochemical data of igneous rocks to examine As concentration variations over ...

Early Triassic microbialites from the Changxing Region of Zhejiang Province, South China

Journal of Palaeogeography, 2019
Microbialites, often considered as a signal of extreme marine environment, are common in the Lower Triassic strata of South China where they flourished in the aftermath of the end-Permian mass extinction.

Low‐Pressure Plasma‐Based Wrinkling of PDMS and Machine Learning‐Driven Property Engineering

Advanced Materials Technologies, EarlyView.
Wrinkled surfaces are well‐suited for controlled surface deformations in the µm range. The key challenge is the relation between the resulting wrinkle features and the necessary process conditions. Machine learning techniques have solved the prediction and inverse design problems for various preparation conditions, opening a precisely controlled ...

Glacial geologic processes

Boreas, 1988
There has long been a need for a book that assembles the diverse information about the processes by which glaciers deposit sediments and create and modify landforms. Drewry has succeeded in compiling much of this material in a very accessible format in Glacial Geologic Processes.
