Chiral Phase Change Nanomaterials

Advanced Functional Materials, EarlyView.
This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...

Unlocking Exceptional Strengthening in Aluminum Alloys via Interstitial Cottrell Atmosphere Formation

Advanced Functional Materials, EarlyView.
Cyclic unloading‐aging‐reloading micro‐tensile tests under various aging durations and temperatures, combined with comprehensive microstructural characterization reveal that the yield point phenomenon in Aluminum‐Carbon (Al‐C) thin films originates from Cottrell atmosphere formation.

Quaternion Averaging

, 2007
Many applications require an algorithm that averages quaternions in an optimal manner. For example, when combining the quaternion outputs of multiple star trackers having this output capability, it is desirable to properly average the quaternions without

Advancing Tandem Organic Solar Cells With Ternary Acceptor Control for High‐Power Modules and Solar‐to‐Ammonia Conversion

Advanced Functional Materials, EarlyView.
Tandem organic solar cells with optimized ternary acceptor engineering achieved a power conversion efficiency of 15.53% and enabled a high‐voltage mini‐module (Voc 6.11 V). Integration into a bias‐free PV‐EC system further demonstrated efficient solar‐to‐ammonia (STA) conversion (97% Faradaic Efficiency, 4± 2% STA efficiency), highlighting scalable ...
