g the criterion of the free energy,we prove that the mechanical equilibrium condition for liquid droups on the condenser surface depends on the angle of contact ( α ). For α >90° the chemical potential of liquid drops on the condenser surface is less than that of spherical drops with the same curvature.
TiO_2 films and SiO_2/TiO_2 multilayers,grown by reactive magnetron sputtering on glass substrates,were characterized with X-ray diffraction(XRD),atomic force microscopy(AFM) and water contact angle measurement.
TiO2 thin films synthesized from aqueous TiOSO4 solution were characterized by X-ray diffractometry (XRD), atomic force microscopy (AFM) and UV-Vis transmittance measurements. The photoinduced hydrophilicity of the TiO2 thin films was investigated.
Because the transparence and anti-fraying performance of the photoresist microlens array is not good, we can obtain better ones by combining melting resist technique with reactive ion etching for transfering the profile to the substrate.
Potential dependences of the angle of contact between perfluorodecaline C10F18 and copper, copper(I) sulfide, and copper telluride Cu4Te3 in 0.1 M CH3COONa are measured.
If the irradiating ion energy is 300-800 eV, the angle of contact increases from 65°-75° to 90°-100°.
The formation of the microdroplets on fibres for the MDT test offers an opportunity to carry out surface tension measurements based on the angle of contact between the resin and the fibre.
The boundary value problem for the velocity potentials is solved using Taylor's assumption on the plate and a contact-line condition that accounts for the dynamic variation of the angle of contact and the vorticity there.
Here, we specify the angle of contact of the surface to the boundary cylinder.
In this work, problems about contact angle have been described and discussed in a way different from that used in some currently popular physics textbooks, for atracting more attentions on the reformation of the textbook content about the properties of liquid.
The boundary element method is used to analyze the influence of pin con- tact angle and pin-hole radius on the potential function of compact tensile specimen under three current input types.The results show that the optimum type is not these three used types which cause more error but anothcr one.
For the problem of Solid—liquid contact，the concepts of macroscopic liquid sur-face，macro—angle of contact， submacroscopic liquid surface and submacro—angle of contactare suggested, and the approximate formula for submacro—angle of contact is given.It is pointedout that the quantitative formula for macro—angle of contact derived from a prevalent molecu-lar theory of contact angle is incorrect beciluse of its overlooking the differences between theabove—mentioned concepts.
