Assembling a True “Olympic Gel” From over 16 000 Combinatorial DNA Rings

open access: yesAdvanced Materials, EarlyView.
Olympic gels are an elusive class of soft matter, consisting of molecular networks held together purely by mechanically interlocked rings. Their topological structure promises unique properties and functions, but their synthesis has proven notoriously difficult.

Dielectric and Gate Metal Engineering for Threshold Voltage Modulation in Enhancement Mode Monolayer MoS2 Field Effect Transistors

open access: yesAdvanced Materials, EarlyView.
Enhancement‐mode monolayer MoS2 FETs with low threshold voltage are essential for low‐power electronics. The threshold voltage can be tuned by the gate metal work function when the semiconductor/dielectric interface is clean. Interfaces between monolayer MoS2 and ZrO2 or hBN allow effective work‐function modulation of the threshold voltage, in contrast

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix

open access: yesAdvanced Materials, EarlyView.
3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

Investigation of Structural, Mechanical and Electrochemical Properties of Temperature‐Dependent Dual AlN/TiAlN Coating Synthesized by CVD Process

open access: yesAdvanced Materials Interfaces, EarlyView.
This study investigates thermally CVD‐deposited AlN/TiAlN dual‐layer coatings over a Si substrate, focusing on the temperature‐dependent process‐structure relationship. Systematic characterization reveals that a dense AlN interlayer combined with an optimally deposited TiAlN top layer provides enhancement in mechanical strength, tribological stability,
