Facile Tri‐Metallic Catalyst Fabrication Using the Dynamic Hydrogen Bubble Template method

open access: yesAdvanced Functional Materials, EarlyView.
Porous metal catalysts are prepared using hydrogen bubbles as a natural template. By carefully selecting metal combinations and thermal treatment, the researchers tailored surface composition and structure, boosting catalytic performance. The approach offers a powerful and flexible route to designing advanced materials for green energy Abstract ...

Synergistic Effects of Entropy Tuning in Niobium‐Based Oxide Anode for Fast‐Charging Lithium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
An entropy‐tuned niobium‐based oxide (ETNO) anode for fast‐charging lithium‐ion batteries are presented, engineered via multi‐cation doping. The synergistic effects of entropy tuning result in excellent rate capability and long‐term durability under ultrafast charging conditions.

Balanced superconductor-insulator-superconductor mixer on a 9~$\mu$m silicon membrane

open access: yes, 2011
We present a 380-520 GHz balanced superconductor-insulator-superconductor (SIS) mixer on a single silicon substrate. All radio-frequency (RF) circuit components are fabricated on a $9 \mu$m thick membrane.

Short-period 520-km observation of the 520 km discontinuity in northern Eurasia.

open access: yes, 1997
Short-period three-component recordings of the seismic wave field of peaceful nuclear explosions (PNEs) along several long-range profiles in northern Eurasia are analyzed to study the structure of the upper mantle. We use the date to search for evidence of the disputed 520 km discontinuity in the mantle transition zone.

The Hierarchical Structure of Sheep Wool and Its Impact on Physical Properties

open access: yesAdvanced Functional Materials, EarlyView.
Sheep wool, a prevalent α‐keratinous fiber, is an essential model for studying protein‐based fibers. Its genetic diversity across breeds enables the establishment of multiscale structure‐property relationships, uncovering previously elusive insights into wool's hierarchical structure.
