Al2O3 Ring Array by Infiltration Synthesis in Polystyrene Antidot Template

open access: yesAdvanced Materials Interfaces, EarlyView.
Different morphologies, such as full dots for genuine PS‐b‐PMMA, residual dots for the PS antidot array (resulting from an Acetic Acid (AA) last PS‐b‐PMMA), and rings for the modified PS antidot array (derived from an O2 plasma last PS‐b‐PMMA), originated from SIS process in PS‐b‐PMMA BCP array, due to the different reaction sites for the TMA precursor

Percutaneous Deployment of the Sinus‐SuperFlex‐DS Stent for Hybrid Stage I Palliation in Neonates Weighing ≤ 2.5 kg: A Multicenter Study

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Hybrid stage I palliation (HS1P) has developed as an alternative to the Norwood stage I palliation for neonates with hypoplastic left heart and related left‐sided obstructive lesions. HS1P is currently used in various clinical settings, such as single ventricle palliation, bridge to decision, bridge to biventricular repair, or ...
