Advanced Functional Materials, EarlyView.This work explores the possibility to design stable periodic magnetization textures by transforming a 2D film into a rolled‐up 3D architecture and back. In case of an isotropic exchange‐biased layer architecture, the magnetization encoded in the 3D state evolves into a spin‐spiral pattern with controlled periodicity after unrolling.

Advanced Functional Materials, EarlyView.Top‐down organic pillaring expands the interlayer spacing of bulk‐sized MoS2 particles while preserving the bulk morphology. Operando X‐ray diffraction and electrochemical dilatometry show that MoS2‐bulk undergoes solvent co‐intercalation in diglyme electrolyte, causing large structural expansion, while pillared, expanded MoS2 suppresses solvent uptake

Advanced Functional Materials, EarlyView.Redox dual‐defects (Cs substitution and O vacancies) in 2D hydrated WO3 steer O2 activation toward selective singlet oxygen evolution. WO‐CO achieves 8.6–15.8 times higher 1O2 production than single‐defect or pristine catalysts, enabling efficient pollutant mineralization via a pathway‐selective photocatalytic mechanism.

Multiple access based on three-stage modulation in multi-band OFDM-UWB system
Tongxin xuebao, 2007 According to the characteristics of multi-band orthogonal frequency-division multiplexing ultra-wideband（OFDM-UWB） system,a multiple access based on three-stage modulation（TSM-MA） was proposed.It combined multi-carrier code division multiple access（MC ...
