Bench Testing Analysis of Perforation Management in the Setting of Bifurcation Coronary Intervention

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Management of coronary perforation in bifurcation lesions with covered stents remains challenging. Aims We aimed to describe a proper practice and toolbox for “jailed‐branch” management after covered stent deployment. Methods Using a bench model, we tested various wires with a 120° angulated microcatheter for their ability to ...

T½ Tuning in a Synergistic BODIPY‐Tetrazole Fe(II) Spin‐Crossover‐Photoluminescence System via Co‐Ligand Variation

open access: yesChemistry – A European Journal, EarlyView.
We report a modular spin crossover‐photoluminescence (SCO‐PL) system: heteroleptic, mononuclear Fe(II) coordination compounds bearing equatorial BODIPY fluorophores that exhibit synergistic PL response upon spin state switching. Exchanging apical nitrile co‐ligands tunes electronic and structural properties, giving precise control over the SCO and PL ...

Silent Partners in the Mill: Unveiling the Role of Additives in Mechanochemical Synthesis

open access: yesChemistry – A European Journal, EarlyView.
Mechanochemistry offers a sustainable, solvent‐free alternative to traditional synthesis, often enhanced by additives in a process known as additive‐assisted grinding. This review discusses how various additives, including liquids, ionic solids, and advanced materials like ionic liquids and piezoelectric compounds, improve reaction efficiency ...

Playing with fire? A mean‐field game analysis of fire sales and systemic risk under regulatory capital constraints

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract We analyze the effect of regulatory capital constraints on financial stability in a large homogeneous banking system using a mean‐field game (MFG) model. Each bank holds cash and a tradable risky asset. Banks choose absolutely continuous trading rates in order to maximize expected terminal equity, with trades subject to transaction costs ...
