Breaking Inversion Symmetry via Vanadium Coordination Engineering in Bismuth Vanadium Selenites

Small, 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.

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

steel 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 ...

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

Metroeconomica, 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.

Alloxazine derivatives as multifunctional agents for photodynamic therapy, cancer cell imaging, and cell proliferation inhibition

Photochemistry and Photobiology, EarlyView.
Alloxazine photosensitizers, molecularly engineered through sugar conjugation and methoxy substitution to enhance solubility, photodynamic potency, and fluorescence, enable image‐guided photodynamic therapy while inhibiting cancer cell growth in the absence of photoactivation.

Energetic microdomains and the vascular control of neuronal and muscle excitability: Toward a unified model

The Journal of Physiology, EarlyView.
Abstract figure legend The capillary–mitochondria–ion channel (CMIC) axis scales structural resources to match functional workload. (Left) In settings of restricted energetic capacity (e.g. cortical neurons), sparse capillary networks and modest mitochondrial pools set a lower energetic ceiling, sufficient to support phasic, low‐workload excitability.
