Fig. 4: Fabrication of SU-8 microchannels using photolithography and sealing of the microchannel with a Bungard dry film laminator. (a) Deposition of SU-8 on PZT subtrate and mask used to pattern the SU-8 channel during photolithography. (b) SU-8 channel after wet etching of a patterned surface. (c) Laminted MHE with Bunduard film laminator. 
Fig. 3: Schematic of the de-pinning process in a closed rectangular microchannel, where the change in width of the film is ∆w. The depinning process proceeds in both directions. The contact angle θc is the measured angle made by the pinned film with the surface of the channel.

Fig. 2: Schematic of the evaporation process in a closed rectangular microchannel. The change in droplet width for either end of the channel is ∆w. The model represents half of the channel width. The contact angle θc is the angle made by the bulk fluid with the surface of the channel.

Kinetic Modelling of Droplet Heating and Evaporation
TL;DR: In this paper, a review of early kinetic models of droplet evaporation is presented, based on numerical solutions to Boltzmann equations for vapour and air, and two regions of gas above the surface of an evaporating droplet are considered: the kinetic and hydrodynamic regions.

Flexible membranes for nanoplasmonic applications
TL;DR: In this article, a general method to make nanoplasmonic devices on a flexible membrane structure, which can be free standing, extremely thin (less than the wavelength of visible light), but retains the ability to be manipulated without loss of optical function, is presented.

Evaporation of a Sessile Droplet on a Substrate
Hua Hu and,Ronald G. Larson +1 more
TL;DR: In this article, the evaporation of a sessile droplet with a pinned contact line was investigated experimentally, by analytic theory and by computation using the finite element method (FEM).

Pattern formation in drying drops
TL;DR: The drop itself can generate one of the essential conditions for ring formation to occur: contact line pinning, and it is shown that when self-induced pinning is the only source of pinning an array of patterns-that include cellular and lamellar structures, sawtooth patterns, and Sierpinski gaskets-arises from the competition between dewetting and contact linePinning.

Influence of Evaporation on Contact Angle
TL;DR: In this paper, the evaporation of sessile drops of water and n-decane placed on various substrates has been studied using a projection method, where drop dimensions and contact angle have been measured as a function of time.
Journal ArticleDOI
Evaporation of microdroplets and the wetting of solid-surfaces
TL;DR: In this article, it is shown that the rate of mass loss is proportional to the height of the droplet and not the spherical radius, which is explained by a model based on a spherical cap geometry and the observed constant value of the contact radius.

Evaporation and the Wetting of a Low-Energy Solid Surface
TL;DR: In this paper, the evaporation of a small droplet of a volatile fluid from a solid surface differs according to whether the fluid wets the surface, and the initial contact angle is less than 90°.
