Redefining the Minimal Editable Unit of Supramolecular Synthons: A 1→2 Lattice‐Editing Strategy in Ternary Multicomponent Crystals

open access: yesAdvanced Science, EarlyView.
Inspired by skeletal editing, we propose a lattice‐editing strategy that extends the minimal editable unit in supramolecular crystals from individual components to local supramolecular structural units, enabling non‐stoichiometric one‐to‐many substitution while preserving the parent lattice architecture.

Deep learning driven uncertainty quantification analysis for combustion modeling of turbulent non-premixed jet flames

open access: yesApplications in Energy and Combustion Science
Chemical kinetic and turbulent combustion model uncertainties can significantly affect the reliability of combustion simulations. Quantifying these uncertainties is therefore essential but remains computationally prohibitive, as classical uncertainty ...

Fire‐Safe Hierarchical Solid Polymer Electrolytes Enabled by Dual‐Functional Microcapsules for Lithium Metal Batteries

open access: yesAdvanced Science, EarlyView.
Dual‐functional fire‐safe microcapsules are integrated into hierarchical solid polymer electrolytes to provide sequential protection against thermal abuse. The ammonium hydrogen phytate‐modified shell forms a protective char barrier, while the thermally triggered release of perfluoro(2‐methyl‐3‐pentanone) actively suppresses combustion, enabling safer ...

Mechanochemical Engineered Sulfur Copolymers Onto Group 13 and Related Fillers Through Lewis Acid‐Base Pairing

open access: yesAdvanced Science, EarlyView.
Green mechanochemical copolymerization was developed for universal interfacial modification of Group 13 and related fillers. By leveraging Lewis acid–base coordination to anchor sulfur‐containing polymers—validated via multiscale characterization and DFT—this versatile method boosts performance across liquid fuels, thermal‐shielding materials, and ...

Reaction-diffusion effects on species mixing rates in turbulent premixed methane-air combustion

open access: yes, 2009
The scalar mixing time scale, a key quantity in many turbulent combustion models, is investigated for reactive scalars in premixed combustion. Direct numerical simulations of threedimensional, turbulent Bunsen flames with reduced methane-air chemistry ...

Hydrogen Production from Ammonia Electrochemical Cracking

open access: yesAdvanced Science, EarlyView.
NH3 electrochemical cracking (e‐cracking) is a complementary technique to centralized thermal cracking for releasing H2 from NH3. In this article, we review recent advances in catalyst development for these cracking techniques and conduct a techno‐economic analysis (TEA) to evaluate the economic feasibility of e‐cracking.

Habitat‐Specific Design Strategies for Untethered Soft Robots

open access: yesAdvanced Science, EarlyView.
Habitat shapes the design of untethered soft robots. Across land, water, air, and living tissues, environmental constraints govern viable combinations of compliant structures, actuation mechanisms, and energy delivery. This review connects these constraints with robotic performance and identifies design principles for advancing adaptable, durable, and ...

A robust autoregressive long-term spatiotemporal forecasting framework for surrogate-based turbulent combustion modeling via deep learning

open access: yesEnergy and AI
This paper systematically develops a high-fidelity turbulent combustion surrogate model using deep learning. We construct a surrogate model to simulate the turbulent combustion process in real time, based on a state-of-the-art spatiotemporal forecasting ...

Turbulent combustion of biomass syngas

open access: yesArchives of Mechanics, 2012
Biomass syngas, a low-calorific gas continuously produced in the process of biomass pyrolysis and gasification, a relatively little-known fuel, can be used for heat production in an industrial plant. However, stringent emission norms have to be fulfilled
