Degradation of superhydrophobic aluminium overhead line conductor surfaces

High Voltage
It has been shown that noise emissions from HV overhead line conductors can be reduced under rain conditions by making their surfaces superhydrophobic. The working environment makes ensuring the longevity of any treatment a major challenge.

Polarity‐Engineered, Tribo‐Positive Imidazolium‐Mediated Crosslinked 6FDA‐Durene Films for Triboelectric Nanogenerator

Small, EarlyView.
Imidazolium‐mediated crosslinking transforms 6FDA‐durene PI from tribo‐negative to tribo‐positive by modulating the surface electronic structure and charge‐transfer behavior. DFT calculations confirm the experimentally observed polarity transition.

An energy-free strategy to elevate anti-icing performance of superhydrophobic materials through interfacial airflow manipulation

Nature Communications
Superhydrophobic surfaces demonstrate excellent anti-icing performance under static conditions. However, they show a marked decrease in icing time under real flight conditions. Here we develop an anti-icing strategy using ubiquitous wind field to improve

Water Droplet Hammer: Piezoelectric Sensing of Ultrafast Mechanical Transients During Droplet Impact

Small, EarlyView.
Droplet impact on solid surfaces produces an ultrafast substrate‐coupled mechanical response that is resolved by PVDF piezoelectric sensing. An initial impulsive strain pulse is followed by interfacial oscillations before rebound. Weber‐number and timescale analyses reveal how droplet inertia, surface wettability, impact regime, and liquid viscosity ...

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

VIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.
