Advanced Science, EarlyView.This study presents a selective thermal transformation of polycarbonate into hybrid carbon materials. The structured carbon enhances electrochemical performance, particularly in lithium‐ion systems. Investigations reveal improved bimetallic ion diffusivity through the hybrid microstructure, contributing to excellent charge kinetics.

The adaptive markets hypothesis through the lens of machine learning
HeliyonThe adaptive markets hypothesis (AMH) postulates that markets are not stationary environments permanently in equilibrium as the efficient market hypothesis (EMH) posits, but evolve over time. However, testing this requires tools that capture the inherent
