Single‐Step Electrochemical Battery Recycling
Advanced Functional Materials, EarlyView.This work demonstrates the use of single‐step recovery, an electrochemical process combining electrodeposition and electro‐dissolution, to recover lithiated transition metal oxides (LTMOs). The batteries produced through this recycling method perform similarly to batteries made from pristine materials.

Numerical study on signatures of atmospheric convective cells in radar images of the ocean
, 1999 Current and wind variations at the ocean surface can give rise to a modulation of the sea surface roughness and thus become visible in radar images. The discrimination between radar signatures of oceanic and atmospheric phenomena can be quite difficult ...

Advanced Functional Materials, EarlyView.This study demonstrates a molecular strategy to enhance the stretchability of conjugated polymers by incorporating plasticizing molecular additives (PMAs). PMAs reduce the persistence length and promote chain entanglement, enabling deformable thin films with preserved electrical performance. A systematic analysis combining rheology, neutron scattering,

Sparse signal representation for complex-valued imaging [PDF]
, 2009 We propose a sparse signal representation-based method for complex-valued imaging. Many coherent imaging systems such as synthetic aperture radar (SAR) have an inherent random phase, complex-valued nature.
