Flow in a double-film-fed fluid bead between contra-rotating rolls, Part 1: equilibrium flow structure [PDF]

open access: yes, 2001
In multiple-roll coaters thin liquid films are transferred from roll to roll by means of liquid ‘beads’ which occupy the small gaps between adjacent rolls.

Frequency-Domain Analysis of Linear Time-Periodic Systems [PDF]

open access: yes, 2004
In this paper, we study convergence of truncated representations of the frequency-response operator of a linear time-periodic system. The frequency-response operator is frequently called the harmonic transfer function. We introduce the concepts of input,

Rolling Nanoelectrode Lithography [PDF]

open access: yesMicromachines, 2020
Non-uniformity and low throughput issues severely limit the application of nanoelectrode lithography for large area nanopatterning. This paper proposes, for the first time, a new rolling nanoelectrode lithography approach to overcome these challenges. A test-bed was developed to realize uniform pressure distribution over the whole contact area between ...
