... Then a liquid with high surface wetting characteristics is applied to the surface of the part and allowed time to seep into surface breaking defects. This liquid is called penetrant. After five or ten minutes the excess penetrant is removed from the surface. ...

... leads to surface-bound poly(L-glutamic acid). This is a convenient route for the preparation of ultrathin layers of surface-bound polyelectrolytes. HBr in acetic acid was used for the hydrolysis of the benzylester group of poly-g-benzyl-glutamate. The hydrolysis of the benzylester group could also b ...

... Qualitative picture of two contributions to a transition metal (TM) density of states (DOS) – free electron-like sp-band, and narrow, structured d-band. Due to the large number of d-states, the d-band dominates the DOS and the varying properties over a TM series can be understood as arising from a d ...

Hydrophobic Hydration
... produced on solution (ΔH/CH2 = -5.4 kJ mol-1) but causes a greater decrease in the entropy (TΔS/CH2 = +7.1 kJ mol-1) [1217]. The increased van der Waals attractions over the liquid gas interface causes γls < γlg. There is also likely to be an overall reduction in volume due to more efficient solute ...

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.
