Laser‐Induced‐Structural Transformation in Ti3CNTx MXene Monitored by Raman Spectroscopy with DFT Insight

Small, EarlyView.
A multi‐wavelength Raman study of microwave‐assisted hydrothermal Ti3CNTx MXene, supported by theoretical calculations, identifies laser‐power thresholds and evaluates its ambient‐condition stability. ABSTRACT MXenes are emerging 2D nanomaterials that have attracted growing attention for their highly tunable atomic structure, composition, and surface ...

Crucial Role of Magnetic Dipole and Anomalous Field Dependence in NiPS3

Small, EarlyView.
Torque magnetometry on the prototypical 2D anisotropic magnet NiPS3, together with relativistic density functional theory calculations, uncovers a distinct intrinsic magnetic anisotropy. The characteristic torque pattern, driven by a high‐field spin‐flop transition, reveals its magnetic response beyond standard XY or XXZ models and highlights the ...

Correlative Operando X‐Ray Imaging and Diffraction Revealing Mechanical Failure Pathways in Lithium Metal Sulfide‐Based All‐Solid‐State Batteries

Small, EarlyView.
This work presents a multimodal operando characterization framework combining operando X‐ray computed tomography and X‐ray diffraction to reveal multiscale degradation mechanisms in sulfide‐based all‐solid‐state batteries. Correlating particle morphology, lattice evolution, and interfacial mechanics uncovers heterogeneous lithiation, crack propagation,

Investigation of Serrated Flow in Intercritically Annealed Medium Manganese Steel by In Situ Synchrotron X‐Ray Diffraction

steel research international, EarlyView.
Serrations and stepwise austenite phase transformation were observed in cold‐rolled and annealed medium manganese steels. By in situ XRD experiments, these two phenomena were studied simultaneously. The results show that DSA leads to the creation of PLC bands and load drops in the specimen.

Multifaceted Behavior and Versatility Features of Ferritic Stainless Steels, Part II: Investigating Electromagnetic, Mechanical, and Corrosion Behavior

steel research international, EarlyView.
This review's second part details the mechanical, corrosion, and electromagnetic behaviors of FSSs. It integrates the foundational microstructure (texture/defects/precipitates) and processing effects from Part I to establish and analyze complex property–property interrelationships critical for high‐performance applications.
