Architecture‐Driven Functional Coupling in Vertically Aligned Nanocomposites
Advanced Functional Materials, EarlyView.Vertically aligned nanocomposites define a growth‐engineered architecture in which vertical interfaces, strain fields, defect pathways, and phase connectivity are created simultaneously. This review shows how these architectural features couple ferroic, optical, ionic, electrochemical, and device responses, establishing design rules and open challenges

Ultra-sensitive single-beam atom-optical magnetometer using weak measurement method
AIP Advances, 2019 Ultra-sensitive measurement of the magneto-optical rotation, due to interaction of linearly-polarized light passing through room-temperature Rb85 atoms, in response to change in longitudinal magnetic field (δBz) is demonstrated using the weak measurement

Polarizing ³He by Spin Exchange with Potassium [PDF]
, 2004 We present experimental studies on the spin-exchange optical pumping of ³He using alkali metal potassium vapor. High ³He polarizations are achieved using lower laser power than traditional rubidium-³He pumping studies.

Advanced Functional Materials, EarlyView.An Alhagi maurorum inspired hierarchical composite membrane (NFCu) was developed by integrating heavy metal remediation and solar‐driven interfacial evaporation in a single platform. Beyond the photothermal effect, a localized photocatalytic process is realized on the CuO surface, deepening the mechanistic understanding of light–matter–water ...

Localized and free exciton spin relaxation dynamics in GaInNAs/GaAs quantum well
, 2008 We have investigated the exciton spin relaxation in a GaInNAs/GaAs quantum well. The recombination from free and localized excitons is resolved on the basis of an analysis of the photoluminescence characteristics. The free exciton spin relaxation time is

Gigahertz circular polarization oscillations in spin-polarized vertical-cavity surface-emitting lasers [PDF]
, 2010 We analyze ultrafast circular polarization oscillations in a commercial vertical-cavity surface-emitting laser after spin injection at room temperature. The circular polarization exhibits faster dynamics than the intensity and longer persistence than the

Advanced Functional Materials, EarlyView.We investigate size‐dependent CO selectivity on Ag nanoparticles, where optimized Ag loading achieves nearly 100% Faradaic Efficiency for CO at −100 mA·cm−2. In situ SERS and XPS reveal the crucial role of optimized loading in catalytic performance. The Ag/C catalyst further exhibits bifunctional activity, enabling efficient electrolysis of CO2 and ...
