In the presence of a Pd0 catalyst, large π‐extended arynes trimerize in an unusual manner to forge extremely compact and strained chiral benzenoids. This new trimerization reaction involves a 1,7‐Pd isomerization, a rare and poorly understood process that is elucidated.

High-Ampacity Power Cables of Tightly-Packed and Aligned Carbon Nanotubes
We characterize the current-carrying capacity (CCC), or ampacity, of highly-conductive, light, and strong carbon nanotube (CNT) fibers by measuring their failure current density (FCD) and continuous current rating (CCR) values.

The local atomic structural variations induced by the internal grain boundaries in copper are utilized to excite phonon vibrations, which facilitates phonon transmission across the copper–graphene van der Waals interface, thereby significantly enhancing interfacial thermal conductance. This study innovatively addresses the bottleneck of melting failure

Self-consistent Modeling of the $I_c$ of HTS Devices: How Accurate do Models Really Need to Be?
Numerical models for computing the effective critical current of devices made of HTS tapes require the knowledge of the Jc(B,theta) dependence, i.e. of the way the critical current density Jc depends on the magnetic flux density B and its orientation ...

A 3D Printing Strategy for Hard Curved Surfaced Circuits: From Materials to Applications
Conventional PCB etching (multi‐step) and indirect transfer techniques fail to meet structural electronics’ demands for lightweight, miniaturized, and customized manufacturing. 3D‐printed conformal circuits enable direct integration of conductive traces into substrates or onto surfaces, achieving integrated structural‐functional fabrication.
