Towards Online Ageing Detection in Transformer Oil: A Review

Sensors, 2022
Transformers play an essential role in power networks, ensuring that generated power gets to consumers at the safest voltage level. However, they are prone to insulation failure from ageing, which has fatal and economic consequences if left undetected or

Mimicking water striders’ legs superhydrophobicity and buoyancy with cabbage leaves and nanotube carpets [PDF]

, 2013
In this work, we have studied the superhydrophobicity and buoyancy of two types of nanostructured surfaces: the cabbage leaf and a vertically aligned carbon nanotubes (VACNTs) carpet. The wettability of these surfaces were characterized by contact angle,

Self‐Driving Underwater “Aerofluidics”

Advanced Science, 2023
Here, the concept of “aerofluidics,” in which a system uses microchannels to transport and manipulate trace gases at the microscopic scale to build a highly versatile integrated system based on gas‒gas or gas‒liquid microinteractions is proposed.

Superhydrophobicity-Enabled Efficient Electrocatalytic CO₂ Reduction at a High Temperature

, 2023
Enhancing the electrocatalytic CO2 reduction reaction (CO2RR) by a temperature increase is very attractive, but lower CO2 solubility and the more intense competitive hydrogen evolution reaction limit the practical implementation.

Toward an experimental proof of superhydrophobicity enhanced by quantum fluctuations freezing on a broadband-absorber metamaterial [PDF]

, 2020
Previous theoretical works suggested that superhydrophobicity could be enhanced through partial inhibition of the quantum vacuum modes at the surface of a broadband-absorber metamaterial which acts in the extreme ultraviolet frequency domain. This effect

A Thermochromic Superhydrophobic Surface [PDF]

Scientific Reports, 2016
AbstractHighly enhanced solid-state thermochromism is observed in regioregular poly(3-hexylthiophene), P3HT, when deposited on a superhydrophobic polymer-SiO2 nanocomposite coating. The conformal P3HT coating on the nanocomposite surface does not alter or reduce superhydrophicity while maintaining its reversible enhanced thermochromism.
