In this study, we propose a versatile method for synthesizing uniform three-dimensional (3D) metal carbides, nitrides, and carbonitrides (MXenes)/metal-organic frameworks (MOFs) composites (Ti 3 C 2 T X /Cu-BTC, Ti 3 C 2 T X / Fe,Co-PBA, Ti 3 C 2 T X /ZIF-8, and Ti 3 C 2 T X /ZIF-67) that combine the advantages of MOFs and MXenes to enhance stability and improve conductivity. Subsequently, 3D hollow Ti 3 C 2 T X /ZIF-67/CoV 2 O 6 composites with excellent electronand ion-transport properties derived from Ti 3 C 2 T X /ZIF-67 were synthesized. The specific capacitance of the Ti 3 C 2 T X / ZIF-67/CoV 2 O 6 electrode was 285.5 F g À 1 , which is much higher than that of the ZIF-67 and Ti 3 C 2 T X /ZIF-67 electrode. This study opens a new avenue for the design and synthesis of MXene/MOF composites and complex hollow structures with tailorable structures and compositions for various applications.

QOL does not significantly differ between primary prevention and secondary prevention ICD recipients. Device recipients had comparable QOL to published, nationwide QOL estimates among non-ICD patients of similar age. The ICD was highly acceptable to most primary and secondary prevention patients.

In contrast to clinical trial results, DES receipt was associated with fewer subsequent revascularization procedures, lower rates of hospitalization for AMI, and improved survival among elderly Medicare beneficiaries.
