n‐Type Semiconductor Hydrogels for Tunable Organic Electrochemical Transistors Operation and Evaporation‐Driven Synergistic Energy Harvesting and Thermal Management

Advanced Functional Materials, EarlyView.
This study develops a tunable n‐OSC hydrogel (PBFDO‐PAAc) platform with a tunable porous network and thermoelectric properties. It demonstrates the first report of n‐OSC hydrogels for evaporation‐driven hydrovoltaic‐thermoelectric electricity generation as well as chemically dedoping‐mediated OECT working mode reconfiguration. This work expands n‐OSCs’

Interaction‐Driven Assembly Pathways in Heterogeneous Active Microrobotic Systems

Advanced Functional Materials, EarlyView.
Peanut‐ and cube‐shaped light‐powered microrobots exhibit distinct magnetic and photocatalytic responses that determine their heterogeneous self‐assembly. In the dark, magnetic dipole interactions drive colloidal copolymerization with cubes acting as nucleation centers, whereas under light irradiation, phoretic interactions compete with magnetic ...

Hydrodynamic field driving effect and mathematical model construction of water quality formation and evolution in coal mine

Meitan xuebao, 2023
The change of regional hydrodynamic field caused by coal mining process affects the multi-field process of the formation and evolution of mine water quality, which may lead to the pollution of the water environment in the coal mining area.

On the Coefficients of a Hyperbolic Hydrodynamic Model

, 2012
Based on the Nakajima-Zubarev type nonequilibrium density operator, we derive a hyperbolic hydrodynamical equation. Microscopic Kubo-formulas for all coefficients in the hyperbolic hydrodynamics are obtained. Coefficients $α_{i}$'s and $β_{i}$'s in the Israel-Stewart equation are given as current-weighted correlation lengths which are to be calculated ...

Microscopic formula for transport coefficients of causal hydrodynamics [PDF]

Physical Review E, 2007
The Green-Kubo-Nakano formula should be modified in relativistic hydrodynamics because of the problem of acausality and the breaking of sum rules. In this work, we propose a formula to calculate the transport coefficients of causal hydrodynamics based on the projection operator method.

Charge‐Tunable Coacervate Micelles for Separator Engineering in Lithium‐Sulfur Batteries

Advanced Functional Materials, EarlyView.
A separator engineering strategy based on charge‐tunable complex coacervate core micelles (C3Ms) is presented to form an ion‐selective layer regulating polysulfide transport in Li–S batteries. The micelles enable uniform adsorption onto commercial polypropylene separators and infiltration throughout the internal pore network, suppressing polysulfide ...

Comparison of Nannochloropsis sp. cells disruption between hydrodynamic cavitation and conventional extraction

MATEC Web of Conferences, 2018
Biodiesel production from microalgae is one of the solution of the future energy problem, but its production cost is still high. One of the costly stages of this process is the lipid extraction process.
