Evaporation Kinetics Engineering Suppressed Bimolecular Recombination in All‐Polymer Solar Cells

Advanced Science, EarlyView.
In this study, phenanthrene (Ph), a volatile solid additive with a weak tendency toward self‐aggregation, is introduced as a donor‐selective morphology regulator in benchmark all‐PSC systems. The moderate evaporation kinetics of Ph enable cooperative crystallization of donors and acceptors, leading to an increased fractal dimension with reduced donor ...

Fractal Geometry: Axioms, Fractal Derivative and Its Geometrical Meaning

Journal of Environmental & Earth Sciences, 2019
Physics success is largely determined by using mathematics. Physics often themselves create the necessary mathematical apparatus. This article shows how you can construct a fractal calculus - mathematics of fractal geometry. In modern scientific literature often write from a firm that "there is no strict definition of fractals", to the more moderate ...

Flame Suppression in Lithium‐Ion Batteries During Thermal Runaway Through Solvent Design Considering the Volatility–Flammability Relationship

Advanced Science, EarlyView.
An asymmetric sulfonate solvent forms thermally stable interphases and demonstrates non‐flammability, suppressing heat accumulation for safer, high‐performance lithium‐ion batteries. ABSTRACT An asymmetric sulfonate‐based linear solvent, 2,2,2‐trifluoromethyl mesylate (FMS), is designed and used as the primary solvent in liquid electrolytes to enhance ...

Disorder‐Driven Ionic Mobility Edge and Localization‐Driven Dendrite Formation in Solid Electrolytes

Advanced Energy Materials, EarlyView.
Migration‐barrier disorder localizes ionic transport into a sparse percolation backbone. Current and electric‐field focusing at filament tips promote fractal dendrite growth and suppress the critical current density according to jcrit = j0 exp(−σEeff/kBT).
