Research Status and Development Trend of Macromolecular Structure and Model Construction of Different Coals

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Coal is a natural macromolecular substance composed of complex organic molecules and a small amount of minerals. Its chemical composition and microstructure are highly complex and variable, and no unified definition exists. This inherent structural complexity underscores the theoretical significance of constructing accurate macromolecular ...

Electrically Induced Liquid Metal Resonance Phenomena

open access: yesAdvanced Physics Research, EarlyView.
This study systematically reveals electrically induced resonance phenomena in liquid metal droplets under square wave AC signal excitation through diverse voltage modulation. Volume‐dependent vibrational responses deviate from classical theoretical predictions, while geometric constraints achieve selective resonance modal control and collective ...
