Spike‐Type Band Alignment via in2Se3/CuI Charge‐Transport Engineering Enables 26% Efficient Lead‐Free RbSn0.5Ge0.5I3 Perovskite Solar Cells

open access: yesAdvanced Materials Interfaces, EarlyView.
A lead‐free and Cd‐free RbSn₀.5Ge₀.5I3 perovskite solar cell is optimized through In2Se3/CuI charge‐transport engineering using SCAPS‐1D. Spike‐type band alignment suppresses interfacial recombination, enhances charge extraction, and achieves a power conversion efficiency of 26.01%, providing an effective strategy for high‐performance and ...

Probability of ruin for a dependent, two-dimensional poisson process [PDF]

open access: yes
A two-dimensional, dependent Poisson risk process is investigated in the paper. Claims are divided into two classes. Within each class claims have the same distribution, but claims belonging to different classes can have different distributions and the ...

Micropillar‐Engineered Hybrid Adhesive Patch for Surface‐Conformable and Directional Adhesion

open access: yesAdvanced Materials Technologies, EarlyView.
This work presents a surface‐conformable hybrid adhesive integrating height‐optimized hexagonal micropillars with open‐rectangular cuts. The micropillars enhance rough‐surface contact and microscale crack arrest, while the cuts guide and reverse interfacial cracks for strong and directional adhesion. The multiscale architecture achieves robust pull‐off

A Direction‐Aware Piezo‐Transmittance Strain Sensor via Engineered Alignment of Carbon Nanotubes (CNTs)

open access: yesAdvanced Materials Technologies, EarlyView.
A direction‐aware piezo‐transmittance strain sensor is realized through the engineered alignment of carbon nanotubes. This anisotropic architecture instantaneously modulates optical transmittance, achieving ultra‐high sensitivity and exceptionally low hysteresis. By effectively eliminating signal crosstalk to precisely decouple multidirectional strains,
