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 ...

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

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.

Bacteria on surfaces: Strength of adhesion does not depend on size of contact area Date: July 11, 2017 Source: Saarland University Summary: Scientists have developed a method with which they can ...

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.

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.

Maintaining a focus on applications in high-performance plastics and composite manufacturing, Onto is said to improve the way materials interact in their intended environment by leveraging reactive ...

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 ...

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.
