Anatomical obstacles in cavotricuspid isthmus detected by modified 2D transthoracic echocardiography and long-term outcomes in radiofrequency ablation of typical atrial flutter

Folia Morphologica
BACKGROUND: Although radiofrequency ablation of the cavotricuspid isthmus (CTI), responsible for sustaining atrial flutter, is a highly effective procedure, in extended patient observations following this procedure, more than 10% becomeunsuccessful ...

Molecular Layer Deposited Aluminum‐Based Hybrid Resist for High‐Resolution Nanolithography and Direct Ultra‐High Aspect Ratio Pattern Transfer

Advanced Materials Technologies, EarlyView.
This study demonstrates an aluminum‐based hybrid photoresist synthesized via molecular layer deposition (MLD) using trimethylaluminum and hydroquinone. The resist achieves sub‐20 nm resolution and virtually infinite silicon etch selectivity, enabling 40 nm‐wide, micrometer‐tall nanostructures.

Sub‐THz Multifunctional Metasurfaces for Independent Transmission or Reflection Phase Manipulation

Advanced Optical Materials, EarlyView.
This article presents a rigorous analysis, design, and characterization of a novel sub‐THz metalens and reflective metasurface. Unlike bulky optical systems, the proposed thin, planar metasurface enables dual‐band full‐space wavefront control, via low‐loss transmission and reflection phase tuning, offering compact integration and improved ...
