Forces and movement of small water droplets in oil due to applied
... The force due to acceleration close to impact was measured to be 5000 times less than the drag force. The gravitational force was measured to be 700 times less than the drag force. These forces were so low that they were neglected. Fig. 6 shows the measured drag force )G[ and the theoretical calcula ...

Plastic nanocomposite insulation material enabling reliable
... The idea is to cover the smallest accessible silica units with a very thin coating layer (preferable a monolayer) of an unpolar agent which leads to a superior distribution of the silica in the PP matrix and avoid a reagglomeration of the silica. This has several advantages. If a distance between th ...

Ultrahydrophobicity
Superhydrophobic surfaces are highly hydrophobic, i.e., extremely difficult to wet. The contact angles of a water droplet exceeds 150° and the roll-off angle/contact angle hysteresis is less than 10°. This is also referred to as the Lotus effect, after the superhydrophobic leaves of the lotus plant. Droplet impacting on these kind of surfaces can fully rebound like an elastic ball, or pancake.
