Toward a Unified Mechanistic Understanding of Polymer Electrolytes for Advanced Solid‐State Batteries

Advanced Materials, EarlyView.
Polymer electrolytes (PEs) are often indiscriminately grouped as “solid polymer electrolytes (SPEs)”, despite fundamental differences in their ion‐transport mechanisms. This Perspective establishes a mechanism‐based framework that distinguishes gel, quasi‐solid, and all‐solid polymer electrolytes based on their dominant ion‐transport pathways.

Burning velocity and the influence of flame stretch [PDF]

, 1991
A new technique is presented for determining burning velocities and stretch effects in laminar flames, and applied to a range of fuel/air mixtures. The speeds of expanding spherical flames, measured by high-speed schlieren cine-photography, are shown to

Comparative chemiluminescence investigation of OH* radicals in laminar and turbulent multi-fuel air- and oxy-fuel flames on semi-industrial and laboratory scale including NOX-formation

Fuel Processing Technology
Chemiluminescence emitted by the de-excitation of excited hydroxyl radicals (OH*), allows for several insights into combustion processes. The presented study investigates air- and oxy-fuel combustion of natural gas with hydrogen enrichment up to 100 ...

Enhanced Photocatalytic H2O2 Production on Terpyridine‐Based Acrylonitrile‐Linked Covalent Organic Frameworks with Asymmetric Localized Electron Distribution

Advanced Materials, EarlyView.
Asymmetric localized electron distribution has been optimized in covalent organic frameworks to enhance *O2 adsorption and facilitate charge transfer, boosting photocatalytic two‐electron transfer oxygen reduction toward H2O2 production from water and air.

Visualization and Emission Spectra of Flames in Combustion Chamber of Swirling-Oxidizer-Flow-Type Hybrid Rocket Engines

Journal of Thermal Science and Technology, 2011
In order to clarify flame behavior in the combustion chamber of swirling-oxidizer-flow-type hybrid rocket engines, a small hybrid rocket engine with a large quartz glass window was fabricated to observe the inside of the combustion chamber from the front

Spiral flames

Applied Mathematics Letters, 2003
This short paper is to describe computations of periodic and meandering spiral patterns in a reaction-diffusion model of flames, regarding the existence of spiral structures and their evolution as functions of the parameters which are representatives of combustion.

Bayesian‐Optimized Dual‐Mode Luminescence‐Based Optical Thermometry Enabled by Negative Thermal Expansion in Lu2(MoO4)3:Yb–Er–Tm Phosphor

Advanced Optical Materials, EarlyView.
A Bayesian optimization framework identifies the ideal composition for Lu2(MoO4)3:Yb–Er–Tm phosphors with minimal experimental trials. By leveraging the host's negative thermal expansion, the material achieves remarkable thermal quenching compensation.

Turbulent flame development in a high-pressure combustion vessel [PDF]

, 2005
The objective of this work was to extend the range of turbulent burning velocities presented in the literature by performing new measurements at elevated pressures over a range of turbulent velocities, u' (r. m. s. deviation from the mean velocity).

Streamline segment analysis of turbulent premixed flames [PDF]

, 2013
In this study the streamline segment analysis has been carried out for turbulent premixed flames in order to analyze the statistical properties of the flame surface, which are associated with the nearby extremal points.
