Self‐Adaptive Non‐Flammable Wallpaper With Layered Bead‐Network Structure for Light Path Modulation Enabling on‐Demand Building Thermal Management

open access: yesAdvanced Science, EarlyView.
A layered bead‐network wallpaper is designed to modulate the light propagation path, overcoming the color residue limitations of thermochromic components for efficient automatic switching between radiative cooling and solar heating modes. The layered bead‐network wallpaper provides passive, all‐season thermal regulation while offering self‐cleaning and

Measurements of Laminar Flame Speeds of Alternative Gaseous Fuel Mixtures

open access: yesJournal of Energy Resources Technology, 2015
Global warming and the ever increasing emission levels of combustion engines have forced the engine manufacturers to look for alternative fuels for high engine performance and low emissions. Gaseous fuel mixtures such as biogas, syngas, and liquefied petroleum gas (LPG) are new alternative fuels that have great potential to be used with combustion ...

Continuous‐Flow Microfluidic Synthesis Enhances C2+ Selectivity for Cu2O Catalysts

open access: yesAdvanced Science, EarlyView.
Microfluidic devices are used to prepare Cu2O nanoparticles under laminar flow conditions, which exhibit enhanced selectivity in the CO2‐to‐C2+ reaction due to their nanoporosity and high defect concentration. Cu2O prepared using standard solution methods displays decreased CO2‐to‐C2+ selectivity due to the absence of similar properties. Altogether, we

Laminar flame speed measurements and laser absorption characterization of high-temperature, premixed ethane–air flames

open access: yesApplications in Energy and Combustion Science
Laminar flame speed, temperature, and pressure measurements were conducted in high-temperature, spherically expanding ethane–air flames. The experiments were conducted in a shock tube, which allows access to a high-temperature regime previously under ...

Experimental Investigation of the Laminar Flame Speeds of GTL Fuel Blends

open access: yes14th International Energy Conversion Engineering Conference, 2016
This work investigates the laminar flame speed of GTL fuel and its 50%-50% blend with conventional diesel, in a cylindrical bomb capable of measuring laminar flame speed, SN, at different initial temperatures and equivalence ratios. SN was measured by analysing the pressure signals inside the bomb after combustion. It was found that pure GTL-Diesel has

From Flow to Function: Using Different Static Mixers to Fabricate Microarchitected Materials Via Chaotic Printing

open access: yesAdvanced Science, EarlyView.
Complex microarchitectures emerge from simple flow‐driven transformations as static mixers iteratively reorient and split material domains. Coupled with diverse deposition strategies, chaotic printing provides an accessible platform for fabricating architected materials that support biologically and chemically relevant processes. ABSTRACT Nature builds

Beyond Traditional Phenolics: Disulfide Bonds for Performance Enhancement of Aerospace Ablation‐Resistant Materials from Processing to Recycling

open access: yesAdvanced Science, EarlyView.
The dynamic disulfide bonds facilitated the development of high‐performance aerospace ablation‐resistant materials. At moderate temperature, the dissociation and recombination of disulfide bonds ensured excellent processability, mechanical properties, and recycling ability of phenolic resin; at high temperature, cleavage of disulfide bonds produced ...
