Scientists uncover how hydrophobic surfaces trap nanoplastics, offering fresh insight into their movement and impact on soil and water systems.

Those energy losses counteract the movement of the contact surface, which increases the adhesive force during separation. Contact ageing, i.e. the formation of chemical bonds on the contact ...

Moreover, the energy required to deform the elastomer and conform to the surface roughness is significantly increased in the presence of water, further reducing initial adhesion.

On the hydrophobic (literally 'water hating') part of the surface, the force is roughly ten times greater than that needed when the bacterial cell adheres to the hydrophilic ('water loving') region.

Hydrophobic coatings, for example, are durable and commercially available. However, they have lower performance in terms of ice and snow repellency compared to state-of-the-art coatings.

They prepared four silicon-based samples relevant to solar panels: (1) smooth hydrophillic (2) nanotextured hydrophilic surfaces and (3) smooth hydrophobic (4) nanotextured hydrophobic surfaces.

From ions to waves, there's a lot of potential energy in the water that covers 70 percent of the planet, and these hydrophobic surfaces could help tap into that energy. Source: UCSD ...
