Unveiling the Microvasculature: The Index of Microcirculatory Resistance and Its Expanding Role in Cardiovascular Care

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Index of microcirculatory resistance (IMR) is a cutting‐edge, wire‐based tool that advances the capability assessment of coronary microvascular function. By utilizing distal coronary pressure and mean transit time under maximal hyperemia, IMR delivers consistent, reproducible insights into the microvasculature's dynamic health.

Semi-blind adaptive spatial equalisation for MIMO systems with high-order QAM signalling

open access: yes, 2008
This contribution investigates semi-blind adaptive spatial filtering or equalisation for multiple-input multiple-output (MIMO) systems that employ high-throughput quadrature amplitude modulation (QAM) signalling.

Moving Beyond 99.9% Coulombic Efficiency for Anode‐Free Sodium Metal Battery

open access: yesCarbon Energy, EarlyView.
Iron‐anchored carbon nanotubes (CNT‐Fe) are developed as a 3D sodiophilic host for anode‐free sodium metal batteries. The Fe nanoparticles significantly enhance sodium adsorption and ensure uniform deposition, enabling an exceptional 99.9% Coulombic efficiency over 1100 cycles and long‐term stability in high‐loading full cells.

Methyl on the Bridge: 2‐Methyl Propellane as Precursor for 1,3‐Substituted 2‐Methylated Bicyclo[1.1.1]Pentanes

open access: yesChemistry – A European Journal, EarlyView.
The synthesis of 2‐methyl propellane and its conversion to various 1,2‐ and 1,2,3‐di‐ and trisubstituted bicyclopentanes is reported. Abstract Bicyclo[1.1.1]pentanes (BCPs) have emerged as isosteric replacements for mono‐ and para‐substituted benzene rings in medicinal and materials applications, involving substitution at the BCP bridgehead (1,3 ...

Synthesis and Isolation of Bismuth Scorpionate Complexes: Toward Bond Activation via Bismuth‐Ligand Cooperation

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT Over the past twenty years, main group chemistry has significantly expanded its scope to include reactivities once considered the exclusive domain of transition metals. Among the emerging concepts, element‐ligand cooperation has proven to be a powerful strategy for enabling bond activation reactions but remains relatively unexplored for ...
