The multipliers of multiple trigonometric Fourier series
Open Engineering, 2016 We study the multipliers of multiple Fourier series for a regular system on anisotropic Lorentz spaces. In particular, the sufficient conditions for a sequence of complex numbers {λk}k∈Zn in order to make it a multiplier of multiple trigonometric Fourier

Fullerene‐Mediated Iodine Immobilization at Buried Interfaces in Sn–Pb Perovskite Solar Cells
Advanced Functional Materials, EarlyView.Indene‐C60 bisadduct (ICBA) accumulates at the buried interface of inverted tin‐lead perovskite solar cells, limiting undesired electron extraction while maintaining efficient hole transport. ICBA simultaneously scavenges molecular iodine, mitigating Sn2+ oxidation and interfacial recombination. This coupled electronic‐chemical regulation delivers 22.7%
