Dual‐Layer Conducting and Redox Polymer Bioanodes for Synergistic Enhancement of Microbial Extracellular Electron Transfer

Advanced Functional Materials, EarlyView.
A hybrid PEDOT/Fc‐LPEI conducting/redox polymer bioanode synergistically improves microbial extracellular electron transfer (EET) in Shewanella oneidensis MR‐1. The dual‐layer interface delivers 18‐fold higher current output and 27‐fold greater charge collected than bare carbon felt, highlighting an effective strategy for high‐performance ...

One-dimensional ultrasound propagation in stratified gas

Archives of Acoustics, 2009
The system of hydrodynamic-type equations is derived by two-sided distribution function for a stratified gas in gravity field and applied to the problem of ultrasound. The theory is based on the generalized Gross-Jackson kinetic equation,

Rarefication Effects on Jet Impingement Loads

Aerospace, 2017
Rarefication effects on jet impingement loads are studied by comparing recent new formulas at the collisionless flow limit and numerical simulations. The jet exit size is finite, and can be either planar or round.

Programming Nanoscale Reaction Environments via Peptide Localization for Gold Nanoparticle Growth in Liposomal Nanoreactors

Advanced Functional Materials, EarlyView.
The liposome nanoreactor method enables uniform metal nanoparticle synthesis using the interior as a reaction environment. We demonstrate that peptide sequences and lipid compositions act as a functional molecular switch to control reaction environments in liposome nanoreactors.

Gradient‐Conductivity Architecture Enables Synchronous Enhancement of Sensitivity and Detection Range in Multifunctional All‐Paper Sensors

Advanced Functional Materials, EarlyView.
A gradient‐engineered all‐paper sensor is fabricated by integrating MXene and in situ grown AgNPs within hierarchical cellulose networks. The device breaks the sensitivity–detection range trade‐off through cascaded conductive pathways, enabling ultrahigh pressure sensitivity, humidity–pressure decoupled dual‐mode sensing, and outstanding EMI shielding,

Water Organization and Hydration‐Dependent Hydroxide Transport in Anion Exchange Membranes (AEM)

Advanced Functional Materials, EarlyView.
Hydroxide transport in anion exchange membranes is governed by the organization of water within the polymer rather than by hydration alone. A hydration‐window framework is presented to unify transport, swelling, and mechanical stability, providing guidance for designing durable membranes for fuel cells and other hydroxide‐based electrochemical ...

Study of the coupling between real gas effects and rarefied effects on hypersonic aerodynamics

, 2012
Hypersonic vehicles travel across the atmosphere at very high speed, and the surrounding gas experiences complicated physical and chemical processes. These processes produce real gas effects at high temperature and rarefied gas effects at high altitude ...

Continuum description of rarefied gas dynamics. II. The propagation of ultrasound

Physical Review E, 2001
The equations of fluid dynamics developed in paper I are applied to the study of the propagation of ultrasound waves. There is good agreement between the predicted propagation speed and experimental results for a wide range of Knudsen numbers.
