Large, outdoor Belt Conveyor Systems for bulk materials are major sources of industrial noise and frequently become an environmental emissions issue for many existing and proposed plants. Deficiencies in the industry’s understanding of the complex, underlying conveyor noise generating mechanisms has meant there are relatively few practical and cost-effective noise management strategies. On the ...

Cellulose nanofibril (CNF) suspensions are not easily coatable because of their excessively high viscosity and yield stress, even at low solids concentrations. In addition, CNF suspensions vary widely in their properties depending on the production process used, which can affect their processability. This work reports roll-to-roll coating of three different types of CNF suspensions with a slot-...

Amongst the ever-growing toolbox of microand nanofabrication techniques, polymer replication-based processes continue to attract attention due to the conceptual simplicity, reproducibility, and great variety of often cheap materials that can be used. Cost and time saving advantages are further provided by high throughput replication techniques such as roll-to-roll nanoimprint lithography [ 1 ]

Organic thin-film transistors (TFTs) are of interest for a variety of large-area electronics applications, such as flexible active-matrix displays and conformable sensor arrays [1]. Among the challenges in the development of high-performance organic TFTs, especially on flexible polymeric substrates, is to realize organic TFTs that simultaneously provide a large field-effect mobility, a large on...

Roll-to-roll (R2R) slot-die coating systems are mostly devoted to the mass manufacture of printed electronics. This study examined the correlation among the operating conditions, thickness, and width of the patterned strip fabricated by the R2R slot-die system. A full factorial experiment was conducted to screen for effective parameters. The velocity of a moving substrate was found to be the mo...

The following approach of a fluidic based self-assembly process uses the surface forces for a precise handling and positioning of small devices for a roll-to-roll manufacturing. The surface, on which the device should be positioned, will be functionalized with hydrophile and hydrophobic areas. Thus water droplets can be caught on the hydrophile areas. The devices to be positioned will be placed...

Technologies based on organic semiconductors may answer the increasing demands that consumers make in the areas of large-area electronics, lightweight displays, and portable computing. Advances in scientific understanding, technology, and device performance have occurred particularly rapidly in the area of polymer light-emitting diodes (LEDs). Material properties and economic considerations sug...
