Revealing the Origin and Nature of the Buried Metal‐Substrate Interface Layer in Ta/Sapphire Superconducting Films

Advanced Science, EarlyView.
The origin and nature of metal‐substrate interface layer in Ta/sapphire‐based superconducting films is investigated using synchrotron X‐ray reflectivity and scanning transmission electron microscopy. An intermixing layer, ≈0.65 nm thick containing Al, O, and Ta atoms, is identified at the interface.

Cyclo‐N9−: a Novel 5/6 Fused Polynitrogen Anion for High Energy Density Materials

Advanced Science, EarlyView.
This study presents a novel 5/6 fused polynitrogen anion, cyclo‐N9−, which is assembled with four cations to form energetic salts. The computational results reveal that the energy densities and detonation performances of these systems are far superior, even surpassing those of CL‐20.

Enhancing Grasping Function with a Thermoresponsive Ionogel Adhesive Glove for Patients with Rheumatic Diseases

Advanced Science, EarlyView.
This study presents a novel portable grasp‐assist glove, weighing only 47 g. The glove integrates smart adhesive pads and a hands‐free control interface based on IMU, designed to aid rheumatic patients with impaired hand function. The system enables switchable adhesion with independent control and detection of user release intent.

2D Metalorganic Ferromagnets

Advanced Science, EarlyView.
The single‐layered 2D metalorganic coordination network Ni‐TCNE, made from Ni atoms and tetracyanoethylene molecules on a gold surface, is established as a ferromagnet with a high magnetic remanence and coercive field. Its Curie temperature is between 10 and 20 kelvin.

Heteroatom‐Synergistic Effect on Anchoring Polysulfides In Chalcone‐Linked Nanographene Covalent Organic Frameworks for High‐Performance Li─S Batteries

Advanced Science, EarlyView.
A series of nanographene‐type covalent organic framework sulfur‐hosting cathodes are developed by introducing pyridine and chalcone functionalities to amend strong lithium polysulfides (LiPSs) interactions to suppress the shuttle effect in lithium‐sulfur (Li─S) batteries. The cathode material showed a specific capacity of 1228 mA h g−1 at 0.5C with 80%
