Single Centre Experience With the Balloon‐Expandable Myval Transcatheter Aortic Valve System in Patients With Bicuspid Anatomy: 1 Year Follow‐Up

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter aortic valve implantation (TAVI) in bicuspid aortic valve (BAV) anatomy remains challenging due to anatomical complexity and limited trial data. New‐generation balloon‐expandable valves, such as Myval, require further evaluation in this subgroup.

Engineering Biochar‐Derived Functional Materials for High‐Performance Supercapacitors: Design Principles, Mechanisms, and Scalable Strategies

open access: yesCarbon Energy, EarlyView.
ABSTRACT Biochar has emerged as a useful and adaptable source of carbon for supercapacitor electrodes. Its value comes from the way biomass chemistry, thermal conversion, and activation conditions shape the resulting pore network, surface groups, and degree of carbon ordering.

Metal Nanoparticles on Halloysite Applied in Stereoselective Hydrogenation of Tetrasubstituted Alkenes

open access: yesChemistry – A European Journal, EarlyView.
Composite materials based on metal nanoparticles supported on a naturally occurring nanotubular clay, halloysite (HAL), led to the diastereoselective hydrogenation of tetra‐substituted alkenes under relatively smooth conditions, mainly oxazolidinone‐based heterocycles.

Benzo[cd]azulenyl: A Structural Isomer of Phenalenyl—Synthesis and Properties of Its Tri‐tert‐butyl‐substituted Derivative and Formation of a Thermal‐ and Photoresponsive σ‐Dimer

open access: yesChemistry – A European Journal, EarlyView.
Benzo[cd]azulenyl, a nonalternant isomer of phenalenyl, is identified as a new member of the nonalternant hydrocarbon radical family. The tri‐tert‐butyl substituted derivative forms a stable σ‐dimer in the solid state. Upon exposure to external stimuli such as light and heat, the σ‐bond of the dimer dissociates, producing the monomeric radical.

A DFT Study on the Mechanism of Selective Formation of Substituted Azepines From 1‐Azabutadienes and Cyclopropanes

open access: yesChemistry – A European Journal, EarlyView.
The origin of the unusual regioselectivity in the Mg‐catalyzed cyclization of azadiene‐type imines with cyclopropanes is elucidated by DFT calculations. Although five‐membered rings are typically favored, energy decomposition analysis reveals that severe steric congestion induces a highly distorted transition state, rendering the five‐membered pathway ...
