Electrothermal Instability in a Porous Medium Layer Saturated by a Dielectric Nanofluid

Journal of Applied Fluid Mechanics, 2016
The onset of convection in a porous medium saturated by a dielectric nanofluid with vertical AC electric field is investigated. The flux of volume fraction of a nanoparticle with the effect of thermophoresis is taken to be zero on the boundaries and the ...

Anchor Engineering of Hole‐Selective Enamine‐Based Self‐Assembling Monolayers for Perovskite Solar Cells

Advanced Science, EarlyView.
This work presents novel enamine‐based self‐assembling monolayers with engineered anchoring groups as hole‐selective contacts for inverted perovskite solar cells. The conjugated molecular design suppresses interfacial defects, optimizes charge extraction, and prevents aggregation.

Suppressing Morphological and Energetic Disorder in Copper Antimony Sulfide‐based Hole‐Transporting Materials via Ligand–Precursor Engineering for Efficient and Stable Perovskite Solar Cells

Advanced Science, EarlyView.
Sulfur‐precursor and ligand engineering regulate the nucleation, morphology, and energetic disorder of CuSbS2 nanocrystals for dopant‐free inorganic hole‐transport layers in perovskite solar cells. Thiourea‐assisted synthesis combined with optimized OAm/OAc coordination suppresses excessive anisotropic growth, enabling mixed plate‐like/quasi‐spherical ...

Electrohydrodynamic Instability in a Heat Generating Porous Layer Saturated by a Dielectric Nanofluid

Journal of Applied Fluid Mechanics, 2017
In this paper, a theoretical investigation has been carried out to study the combined effect of AC electric field and temperature depended internal heat source on the onset of convection in a porous medium layer saturated by a dielectric nanofluid.

Multimodal Bioinspired Self‐Healing Composites Enabling Durable and High‐Efficiency Wearable Perovskite Light‐Emitting Diodes

Advanced Science, EarlyView.
Butterfly wing–inspired intrinsically self‐healing polymer interlayers enable flexible perovskite optoelectronics with high luminance, strain‐insensitive stability, and environmental resilience. These hierarchically structured films redistribute mechanical stress, suppress defect formation, and maintain performance under repeated bending, paving the ...
