Real Analysis Exchange, 1995 Suppose \(X\) to be a compact metric space, \(w_1, w_2, \dots , w_m\) invertible contractive selfmaps. The iterated function system \((X;w_1,w_2,\dots ,w_m)\) satisfies the open set condition, if \(X\) is an attractor of the system \((X,w_1,w_2,\dots ,w_m)\) and there is a nonvoid open \(O\subseteq X\) such that \(w_i[O]\cap w_j[O]=\emptyset\) for \(i ...

A Dual‐Functional Electrolyte Additive for Highly Reversible Zinc‐Ion Batteries
Advanced Functional Materials, EarlyView.This study introduces tetrabutylammonium bromide (TBAB) as a dual‐function additive for aqueous zinc‐ion batteries. TBAB disrupts the hydrogen‐bond network of water while TBA+ adsorbs on Zn to improve interfacial wettability and regulate Zn2+ flux, resulting in suppressed dendrite growth and parasitic reactions. This synergy extended the lifespan of Zn|
