Sticker Valence Governs Chain Collapse and Liquid‐Liquid Phase Separation in Peptide‐Inspired Associative Polymers

Advanced Science, EarlyView.
Peptide‐inspired associative polymers with arginine‐like guanidinium stickers and lysine‐like ammonium spacers undergo chain collapse and liquid‐liquid phase separation induced by reversible sticker associations. Sticker valence and tunable association strength jointly control the phase behavior, chain conformation, and interfacial cohesion of these ...

Topology and flame speeds of turbulent premixed flame kernels in supersonic flows

Combustion and Flame, 2019
Abstract Premixed flame kernels exposed to a mean expanding supersonic channel flow are examined using experiments and large-eddy simulations. Four cases, spanning three Mach numbers and two equivalence ratios, are explored. Numerical results are processed similarly to and compared with experimental data.

Hydrogen‐Bond Enabled Phosphite Based Intrinsic Flame‐Retardant Solid‐Solid Phase Change Materials Using Catalyst/Solvent‐Free Multi‐Component Reaction for Battery Thermal Management

Advanced Science, EarlyView.
The phosphite group endows intrinsic flame retardancy, while the P = O bond enhances intermolecular interactions to realize solid‐solid phase transition. Battery thermal management tests show the materials extend the safe working time of lithium‐ion batteries by 200%. Cone calorimeter tests indicate a 14s delay in ignition time, and reductions of 37.6%,

Experimental study of turbulent premixed flames of gas-to-liquids (GTL) fuel in a fan-stirred combustion bomb

Results in Engineering
This study experimentally investigates the turbulent flame speeds (St) of Gas-to-Liquids (GTL) fuel and a 50/50 blend with diesel across turbulence intensities (u') ranging from 0.5 to 3.0 m/s and equivalence ratios (Φ) from 0.7 to 1.3.

Flame Annihilation Displacement Speed and Stretch Rate in Turbulent Premixed Flames

Flow, Turbulence and Combustion, 2019
This paper examines the dynamics of flame annihilation in turbulent premixed flames using a DNS dataset of Haghiri et al. (J. Fluid Mech. 843, 29 2018). Two theoretical frameworks are considered. The relative contributions of the reaction rate, normal diffusion and flame curvature to the flame displacement speed are first considered.

From Fluoride Removal to Interfacial Reactivity Enhancement: Functionalized La3+‐Crosslinked B/CuO Energetic Microspheres

Advanced Science, EarlyView.
A fluoride adsorption‐functionalization strategy directly couples fluoride wastewater remediation with combustion performance enhancement of B/CuO energetic microspheres. Fluoride captured from wastewater is retained within the microspheres without adsorbent regeneration or disposal, simultaneously achieving pollutant removal and enhanced energetic ...

Oral Nanomicelle‐Mediated Sequential Butyrate Production in the Intestine for Ulcerative Colitis and Immunosuppression Treatment

Advanced Science, EarlyView.
After oral administration, inodorous GLU‐BA self‐assembles into nanomicelles in aqueous environments to resist premature gastric adsorption. Upon reaching the intestine, endogenous esterases rapidly cleave the built‐in ester bonds in these nanomicelles to release BA and GLU, with GLU further metabolized by gut microbiota to gradually generate BA ...

Turbulent and Stable/Unstable Laminar Burning Velocity Measurements from Outwardly Propagating Spherical Hydrogen-Air Flames at Elevated Pressures

Journal of Thermal Science and Technology, 2006
The laminar burning velocity of pre-mixed hydrogen-air mixtures was measured in a fan stirred combustion bomb. Unstretched laminar burning velocities and Markstein lengths were obtained at 0.10MPa for equivalence ratios of 0.4, 0.6, 0.8 and 1.0 using ...

Oligosaccharides With Defined Glycosidic Bonds Shape Gut Microbial Succession and Metabolism Via Bond‐Specific Microbial Responders

Advanced Science, EarlyView.
Oligosaccharides with defined glycosidic bonds drive divergent gut microbial succession and shape unique metabolic profiles. Absolute time‐series profiling with Bayesian generalized Lotka–Volterra modeling identifies bond‐specific microbial responders, while monoculture validation and metaproteomics reveal linkage‐matched transport and cleavage modules.
