Design Parameter Analysis of a Roll-to-Roll Printing Machine

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...

Tension Estimation by Using Register Error in Roll to Roll e-Printing Systems

The focus of this study is on development of mathematical model and experimental verification of a tension estimation using the register error in R2R (Roll to Roll) e-Printing systems. In a printing section of conventional R2R printing systems, the tension is generally measured not for controlling but for monitoring because the tension control causes the occurrence of a register error. But the ...

Applications of Carbon Nanotubes for Lithium Ion Battery Anodes

Carbon nanotubes (CNTs) have displayed great potential as anode materials for lithium ion batteries (LIBs) due to their unique structural, mechanical, and electrical properties. The measured reversible lithium ion capacities of CNT-based anodes are considerably improved compared to the conventional graphite-based anodes. Additionally, the opened structure and enriched chirality of CNTs can help...

Testing of Carbonaceous Nanomaterials for Improved Lithium Ion Battery Anodes

Fossil fuels are our major source of energy, but they are depleting quickly. They also create major environmental issues such as climate change by causing the emission of carbon dioxide and other greenhouse gases. As a result, clean and renewable sources of energy such as solar, nuclear and wind are being considered as alternatives to fossil fuels. Some renewable energy sources are intermittent...
