Higher-resolution flexography is essential to manufacturing low-cost, large-area printed electronics and current production methods are limited in size due to contact-mediated liquid instabilities. Flexography Using Nanoporous Stamps can achieve continuous of micron-scale features with uniform nanoscale thickness at ~m/s speeds. This represents a combination of resolution and throughput that far surpasses current industrial printing technologies. The nanoporous stamp technology could be used to build machines for printing electronics in new formats, such as for large displays, smart packaging, and ubiquitous wireless sensors.

Friction Stir Welding is a solid-state joining process in which two metal pieces are joined together via mechanical intermixing; it is often used in building cars, trains, robots, ships, and more. Through the Tool Tracking for Friction Stir Welding is a technique to keep a weld tool on track by utilizing only force sensors on the friction stir welding tool. It’s beneficial for manufacturing since it can do corrections in real time, is cost-effective since no other sensors are required, and increases the robustness of the Friction Stir Welding process.

Current processes for manufacturing metal oxides or sulfides can be complicated. A new technique using microwave-assisted heating, is an ultrafast and more energy-efficient method of manufacturing these nanomaterials. Microwave-initiated Ultrafast Nanomanufacturing can make it much quicker and lower cost to mass-produce these nanomaterials that can be used in lubricants, solar cells, lithium-ion batteries, and high performance protective composites.

Atmospheric pressure plasma discharge is used to fragment and polymerize small molecules as a method of Manufacturing Functional and Transparent Coatings. The manufacturing process can grow a wide range of materials, including silica, metal oxides, nitrides, and polymer coatings, onto both organic and inorganic substrates. There are obvious benefits for scalability by using a naturally abundant gas like compressed air to facilitate a coating process. Additionally, there is a significant reduction in chemical waste during the manufacturing process. Reinhold Dauskardt, Stanford University

A new Nanorobotics Platform for Nanomanufacturing combines controlled movement of nanorobots with unique light focusing or blocking abilities for direct surface writing and provides researchers with considerable freedom for creating diverse features with different shapes and sizes. This versatile production method could lead to a new ‘on-the-fly’ nanomanufacturing platform and create new opportunities for surface science and the production of nanodevices which could be used in a variety of fields including computers, energy, chemicals, and more.
