UNLABELLED Since its introduction in 1995, nanoimprint lithography has been demonstrated in many researches as a simple, low-cost, and high-throughput process for replicating micro- and nanoscale patterns. Due to its advantages, the nanoimprint lithography method has been rapidly developed over the years as a promising alternative to conventional nanolithography processes to fulfill the demands...

The stability of multi-input and multi-output web-tension systems is an important factor that is required for the roll-to-roll printing machines. This paper analyzes stability for design parameters of a web-tension system of a high-speed gravure printing machine. Analyzed parameters include moment of inertia of the passive dancer, viscous friction coefficient of the dancer system, distances fro...

A novel roll-to-roll flexographic printing process for rechargeable zinc-based battery manufacturing was presented in this paper. Based on the fundamental operating mechanism of flexography, key criteria for developing functional flexographic printing inks were established, including composite ink rheology (steady-state viscosity and yield stress), ink wettability as well as ink dispersing qual...

Roll-to-roll large-format coating and UV embossing processes aim to revolutionise the manufacturing of functional films, with the ability to process a largearea at one time, resulting in high throughput and cost reduction. In this article, we present the experimental results obtained during the process development for roll-toroll large-format coating and UV embossing. We have investigated key a...

This report presents the analyses, results and recommendations of an investigation into the specification and determination of a platform's roll radius of gyration and its influence on the measured or predicted roll response of a maritime platform. The investigation and report seek to resolve known deficiencies in the specification and determination of roll radius of gyration and provide direct...

Ant foragers are known to memorise visual scenes that allow them to repeatedly travel along idiosyncratic routes and to return to specific places. Guidance is provided by a comparison between visual memories and current views, which critically depends on how well the attitude of the visual system is controlled. Here we show that nocturnal bull ants stabilise their head to varying degrees agains...

Kubina, VŠB – Technical University of Ostrava, Faculty of Metallurgy and Materials Engineering, Ostrava, Czech Republic The application of finite element simulation to the problem of roll pass design for round bar rolling is considered. Two roll p...

A Forced Roll Mechanism was designed and built at the Hydromechanics Laboratory at the United States Naval Academy. The FRM was designed as a dynamometer that forces a planing hull model in roll and measures the resulting roll moment as well as the heave and sway forces. The model is fully restrained in all six degrees of freedom. The dynamometer can be configured to either oscillate the model ...

Transfer printing is a nanofabrication technique that involves an assembly process by which a printable layer can be transferred from a transfer substrate to a device substrate. Future application of transfer printing toward a roll-to-roll printing process of flexible devices hinges upon the understanding on the mechanisms governing transfer printing quality, which is far from mature. So far, t...

This work presents a low-aspect-ratio (LAR) inertial microfluidic design compatible with roll-to-roll (R2R) hot embossing for size-based cell or microparticle separation in a low-cost and disposable format. The device consists of two segments of LAR channels in which inertial lift forces are used to differentiate lateral positions based on size for separation downstream. Separation of 18μm and ...
