Recent Advances in Wide‐Bandgap Perovskite Solar Cells
Advanced Materials, EarlyView.Ubiquitous defects predominately account for photo‐instability and open‐circuit voltage losses in wide‐bandgap perovskite solar cells (WBG PSCs). This review comprehensively presents the underlying impact mechanisms, summarizes the advanced optimization strategies across various functional layers and their interfaces to develop efficient and stable WBG

Biomimetic Dynamics of Nanoscale Groove and Ridge Topography for Stem Cell Regulation
Advanced Materials, EarlyView.Dynamic nanoscale groove‐ridge structures are engineered by flexibly conjugating RGD‐magnetic nanoparticles to nanogroove templates with variable groove widths at the molecular scale. Magnetic control enables cyclic switching between nanoscale groove and ridge states that modulates ligand accessibility of cellular integrins.

Seismic Isolation Materials for Bored Rock Tunnels: A Parametric Analysis
InfrastructuresMost recent tunnel designs rely on more thorough analyses of the intricate rock interactions. The three principal techniques for excavating rock tunneling are drill-and-blast for complete or partial cross-sections, TBM only for circular cross-sections ...

Where Does the Money Go: The Increasing Reliance on Household Debt in Canada [PDF]
Recent studies show that Canadians are increasingly worried about their financial wellbeing at retirement and into the golden years. Counter-intuitive as it may seem however, the household savings rate continues to plunge as Canadians take on more and ...

Study on the size effect of rock elastic modulus considering the influence of joint roughness
Frontiers in MaterialsThe elastic modulus of rocks is a measure of the ability of rocks to resist elastic deformation. It is related to the size of rocks and can effectively measure the internal physical and mechanical strength of rocks.
