Magnetism in Re-based ferrimagnetic double perovskites

open access: yes, 2009
We have investigated spin and orbital magnetic moments of the Re 5d ion in the double perovskites A2FeReO6 (A=Ba, Sr, Ca) by x-ray magnetic circular dichroism (XMCD) at the Re L2, 3 edges.

Structural Principles of A-site ordered double perovskites: ferroelectric CaMnTi2O6 as a model system

open access: yes
Perovskites are a broad and versatile class of crystalline materials. Their unique structure combined with the countless possible ionic combinations makes them highly tunable and gives rise to many possible properties such as piezo-, pyro-, and ...

Laughing all the way to the bank? Alternative comedy in the provinces

open access: yes, 1994
Metropolitan snobbery and the logistics of scale both militate against the success of comedians working in the regions. Yet, as Oliver Double here argues, the scene has been a lively one, often daring in its style and range alike – at least until the ...

Crossover From Excitonic to Bulk Emission in Metal Halide Perovskite Nanocomposites

open access: yesAdvanced Optical Materials, EarlyView.
A transition from excitonic to free‐charge recombination is uncovered in perovskite nanocomposites as a function of nanostructure size using PLQY(R, F) mapping as a function of excitation fluence (F) and repetition rate (R). These findings demonstrate that PLQY(R, F) mapping serves as a powerful and non‐invasive tool to extract quantitative information

Wavy‐Interlocked Stretchable Triboelectric Nanogenerators Enhanced by Liquid Metal Microflowers for Self‐Powered Wearable Motion Monitoring

open access: yesAdvanced Science, EarlyView.
Schematic showing a stretchable triboelectric nanogenerator based on interlocked wavy architectures that uses EGaIn microflower‐embedded PVDF‐TrFE and Nylon‐6 nanofiber membranes. The multi‐petaled, electron‐rich EGaIn microflowers enhance interfacial polarization and capacitance, while the interlocked wavy architecture enlarges the effective contact ...

Sustainable Materials Design With Multi‐Modal Artificial Intelligence

open access: yesAdvanced Science, EarlyView.
Critical mineral scarcity, high embodied carbon, and persistent pollution from materials processing intensify the need for sustainable materials design. This review frames the problem as multi‐objective optimization under heterogeneous, high‐dimensional evidence and highlights multi‐modal AI as an enabling pathway.
