The Characteristics of Methane Combustion Suppression by Water Mist and Its Engineering Applications

Energies, 2017
To safely mine coal, engineers must prevent gas combustion and explosions, as well as seek feasible and reasonable techniques to control for these types of incidents. This paper analyzes the causes and characteristics of methane combustion and explosions.

A simulated study on the effect of water temperature on cooling efficiency of water mist fire exting

Journal of Thermal Engineering, 2020
In this paper, the effect of initial water temperature on the cooling performance of a water mist fire suppression system has been investigated. A zero-dimensional analytical model was first developed to study the thermal and dynamic behavior of a single

Adsorption‐Engineered Hydrocarbon Ionomers for Durable Proton‐Exchange Membrane Fuel Cells

Advanced Materials, EarlyView.
Hydrocarbon ionomers suffer from oxidation‐driven interfacial degradation in PEM fuel cell cathodes, leading to catalyst instability. Here, adsorption‐engineered poly(fluorene) ionomers decouple interfacial anchoring from oxidative degradation, enabling strong catalyst–ionomer interactions while resisting electrochemical oxidation.

Directing Near‐Perfect (001) Orientation in Wafer‐Scale BiOI Thin Films via Halide‐Mediated van der Waals Stacking

Advanced Materials, EarlyView.
Our work introduces a new framework that fundamentally changes how orientation in bismuth oxyhalide systems is approached. Comprehensive experiments, backed by theoretical models, reveal the pivotal role of halide anions to modify the van der Waals stacking energies required to direct orientation. Our method enables the fabrication of near perfect (001)

High Throughput Aerosol Jet Printing to Operationalize High Aspect Ratio Patterning

Advanced Materials Technologies, EarlyView.
High‐throughput aerosol jet printing poses distinct limiting mechanisms to the printing process. These include rapidly changing ink chemistries, atomization instabilities, and liquid‐phase spreading. The combination of in‐line heating, process monitoring, and traditional optimization procedures enables rapid printing of high‐aspect‐ratio structures ...
