Breaking Inversion Symmetry via Vanadium Coordination Engineering in Bismuth Vanadium Selenites

open access: yesSmall, EarlyView.
Vanadium coordination engineering induces symmetry breaking in bismuth selenites by transforming symmetry‐compensated VO6/VO5F units into directionally aligned VO5 polyhedra. The resulting non‐antiparallel vanadyl arrangement eliminates dipole cancellation and stabilizes a polar noncentrosymmetric framework with nonlinear optical activity.

Quantitative Analysis of Topographic Crosstalk in DART‐ESM Arising from Feedback‐Loop‐Delay‐Induced Contact Stiffness Variations in Battery Materials

open access: yesSmall Methods, EarlyView.
Interpretation of Dual AC Resonance‐Tracking Electrochemical Strain Microscopy (DART‐ESM) signals is complicated by topography‐induced artifacts that distort measured responses. Using silicon with artificial trench structures as a reference, this study quantifies artifact magnitude and demonstrates that Cooling Cross‐Section Polishing (CCP) effectively

Near‐Atomic Investigation on the Elemental Redistribution During Coprecipitation of Nano‐Sized Kappa‐Type and B2 Precipitates in an Al‐Alloyed Lightweight Steel

open access: yessteel research international, EarlyView.
Elemental redistribution during coprecipitation of kappa (κ)‐type and B2 precipitates in an Al‐alloyed lightweight steel is revealed by atom probe tomography (APT) and density functional theory (DFT). Fe and Ni redistribution promotes the evolution of B2 phase from NiAl‐type toward FeAl‐type and improves the stability of κ and B2 phases during ...

An induction heating system for in situ X‐ray diffraction imaging: design, simulation and application to dislocation dynamics in semiconductors

open access: yesJournal of Synchrotron Radiation, EarlyView.
This work presents a compact induction heating system for time‐resolved in situ X‐ray diffraction imaging. The system enables contact‐free volumetric heating up to approximately 1600°C and provides flexible operation in different operating modes. Its performance is demonstrated through representative diffraction imaging experiments.We present a compact

How Are “Financial Balances” Financed? Wicksell, (Keynes) and the US Mainstream Don't Fit Today's Institutions; Kalecki, Triffin, and Minsky Got it Right

open access: yesMetroeconomica, EarlyView.
ABSTRACT The paper examines the financial balances of the US economy. Government is the main borrower and households and the foreign sector the main lenders. Business net lending is minimal. The balances and their underlying transactions contradict the loanable funds theory and its “global savings glut” variation.
