Bioinspired Adaptive Surfaces for Intelligent Liquid Manipulation: Progressing From Passive and Active to Hybrid Strategies

Advanced Materials, EarlyView.
This review examines passive, active, and hybrid liquid manipulation strategies, highlighting hybrid approaches as an emerging route to reconcile energy efficiency with adaptive control. By actively reconstructing passive surfaces to store programmable interfacial energy, hybrid systems enable flexible yet low‐power liquid transport, with perspectives ...

Hydrophobic MFI‐Type Zeolites via Alkali‐Cation‐Induced Defect Healing: Implications for Adsorbent and Catalyst Design

Advanced Materials, EarlyView.
Sub‐stoichiometric amounts of Na+ or K+ enhance defect healing during Silicalite‐1 (MFI) and TS‐1 calcination by promoting Si–O–Si annealing and healing framework vacancies. The resulting defect‐free zeolites are more hydrophobic and show improved butanol/water separation and improved activity and selectivity in the epoxidation of 1‐hexene, offering a ...

Specific Position of Halogen in Crystalline TADF Scintillators Enables Efficient Triplet Harvesting Through Vibrational Modulation of Spin–Orbit Coupling

Advanced Materials, EarlyView.
Specific ortho‐halogenation transforms crystalline TADF emitters into efficient organic scintillators. Fluorine reduces the effective singlet–triplet separation, while chlorine combines near‐degenerate excited states with vibrational modulation of spin–orbit coupling.

A model of local thermal non-equilibrium during infiltration

Advances in Water Resources, 2019
Abstract A realistic temperature estimation is crucial for many earth-science applications, ranging from hydro-thermal systems to plant physiology. The most common approach to calculate the temperature in multi-phase systems assumes immediate local thermal equilibrium (LTE) between the phases.

Local thermal non-equilibrium in porous media with heat conduction

International Journal of Heat and Mass Transfer, 2018
Abstract In classical theory of porous media, a local thermal equilibrium between fluid phase and solid phase is assumed. According to this theory, the fluid and solid temperatures reach an equilibrium temperature value rapidly. However, in porous media, the rate of heat transfer between the fluid and solid may not be fast enough to achieve a local ...

Thermal Convection in a Partially Porous Rotating Chamber Using Local Thermal Non-Equilibrium Models

Transport in Porous Media, 2022
The effect of a porous layer on thermal convection in a closed rotating square chamber has been studied in this paper. The left border of the chamber is heated up, the right one is cooled, and other walls are thermally insulated. The governing relations with the initial and boundary conditions written employing stream function and vorticity variables ...

Rayleigh waves in thermoelasticity: Triple porous media in local thermal non-equilibrium

Mathematics and Mechanics of Solids, 2022
Assuming the hypothesis of local thermal non-equilibrium, this work investigates the propagation of Rayleigh surface waves in a thermoelastic half-space, isotropic, homogeneous and structured with a triple level of porosity. Its surface is supposed to be stress-free, thermally insulated and characterized by null pressure boundary conditions. A class of

A model for thermal protection ablative material with local thermal non-equilibrium and thermal radiation mechanisms

Acta Astronautica, 2021
Abstract Novel resin-based ablative materials are manufactured for the Thermal Protection System (TPS) of hypersonic aircraft in recent years to adapt more extreme aerothermodynamic environment. The establishment of theoretical model and simulation method for accurately predicting material's responses can guide design of TPS and significantly reduce ...
