Flexible perovskite solar modules: Fabrication strategies and future prospects
We first systematically summarized the fabrication strategies for flexible perovskite solar modules, including scalable coating and printing, interface engineering, low‐temperature crystallization, and mechanical reliability design. Then we emphasize how process control, material design, and module integration work together to enable high‐performance ...

Vinyl content governs the long‐term ageing resistance of SBS‐modified bitumen. Multiscale AFM, FM, SEM, and FTIR analyses show that low‐vinyl SBS copolymers (L‐SBS, B‐SBS) undergo pronounced bee‐phase growth, stiffening, and network fragmentation after PAV ageing, whereas high‐vinyl variants (HV‐SBS, DB‐SB) retain their morphology and chemistry ...

Obstructive sleep apnea (OSA) is characterized by recurrent upper‐airway collapse, which generates key nocturnal stressors including intermittent hypoxia, sleep fragmentation, intrathoracic pressure stress, and sympathetic activation. These physiological disturbances converge on shared biological mechanisms, including oxidative stress, inflammation ...

Hydrogel culture mimicking young and aged ovarian stromal stiffness recapitulates key features of reproductive aging, including impaired follicle growth, transzonal projections (TZPs), and oocyte quality. Silencing Smad7 rescues TZPs and oocyte quality in stiff hydrogels, identifying ECM mechanics as a driver and therapeutic target in ovarian aging ...

Surface and Boundary Corrections in Peridynamics Using Optimized Nodal Influence Weights
ABSTRACT Peridynamics (PD), similarly to some other nonlocal continuum theories, exhibits truncated interaction horizons near free surfaces, cracks, and voids in bounded domains. This loss of neighbors causes artificial surface effects and inconsistencies in the derivative and energy operators that persist under discretization refinement, limiting PD ...
