In Situ Generation of Gel Foam via Heat‐Accelerated Calcium Ion Release From Nano‐CaCO3 for Lithium‐Ion Battery Fire Suppression and Prevention

open access: yesAdvanced Science, EarlyView.
We present a heat‐accelerated in situ crosslinking strategy to create an alginate gel foam for lithium‐ion battery fire suppression. At ambient temperature, the formulation maintains low viscosity for easy foam generation. After exposure to fire, δ‐gluconolactone hydrolysis accelerates, enabling rapid Ca2+ release from CaCO3 and rapid ionic ...

Research on Diaphragm Pump Fault Diagnosis Method Based on Res‐DCB‐Net

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Nonstationary pressure pulsation signals of diaphragm pumps contain strong background noise and coupled characteristics. This makes it challenging to extract incipient fault features and to decouple faults with similar physical mechanisms. To address these limitations, this paper proposes a spatiotemporal fault diagnosis model named Res‐DCB ...
