Two-dimensional numerical experiments of convection. [PDF]
, 1996 PhDI report the results of numerical studies of 2-dimensional fully compressible convection of a fluid in which the dependence of the radiative conductivity on temperature T is taken as K, (V + aT -5)1 so that central regions of the layer are unstable ...

A Miniaturized Autonomous Thermomagnetic Generator
Advanced Functional Materials, EarlyView.Micro, autonomous and high power thermomagnetic generator operating between a heat dissipator and a processor. ABSTRACT Thermomagnetic generators (TMG) are promising devices for converting low‐grade waste heat into electricity. Self‐actuation using permanent magnets is the key to autonomy.

How the Porous Transport Layer Dictates Membrane Electrode Assembly Performance of IrO2 Catalysts
Advanced Functional Materials, EarlyView.The Schottky barrier formed at the catalyst | PTL interface critically governs both the initial performance and long‐term durability of the PEMWE, and its magnitude is dictated by the catalyst's work function. This limitation can be resolved by combining a rutile IrO2 core for efficient electron transfer with an amorphous IrOx shell for high surface ...

Advanced Functional Materials, EarlyView.Antisolvent Vapour‐Assisted Crystallization (AVAC) enables controlled perovskite crystallization through precisely metered antisolvent vapour, eliminating liquid antisolvent waste. Compatible with roll‐to‐roll (R2R) slot‐die coating, AVAC produces uniform, pinhole‐free films with enlarged grains, delivering efficiencies of 18.3% for R2R fabricated ...

Convection in fluid and porous media [PDF]
, 2003 The subject of convection in fluid and porous media is investigated. Particular attention is paid to penetrative convection. The first two chapters are devoted to penetrative convection when fluid overlies and saturates a porous medium.

Advanced Materials, EarlyView.In the proposed model, a photoinduced nanoreactor uses Cu2O self‐photooxidation to generate localized supersaturation. A metastable supersaturation state first forms a shell, creating a spatially confined environment that restricts reactant exchange; continued Cu release then drives the local environment toward a labile regime that favors predominantly

Stability of weak solutions of a non-Newtonian polytropic filtration equation
Electronic Journal of Differential Equations, 2018 We study a non-Newtonian polytropic filtration equation with a convection term. We introduce new type of weak solutions and show the existence of weak solutions.
