Why is this technology needed?

The batch processing of nanoparticles (NPs) makes it difficult to control NP agglomeration, which can significantly affect NP properties. Further, centralized batch processing requires shipment, sometimes over long distances by truck and train, increasing public exposure to potentially hazardous NPs. To keep NPs from agglomerating during shipment, chemical companies must use expensive, toxic surfactants that can make downstream NP functionalization difficult.

How does this technology address the need?

Our vision is that manufacturers of next generation solar cells, solid state lighting, LCD displays, catalysts, lubricants, batteries, heat exchangers and many other high-tech products will produce and functionalize NPs just in time at the point of deposition (Figure 1). They will accomplish this through the use of high-throughput microreactors providing heating and mixing rates several orders of magnitude faster than conventional batch (stirred tank) reactors. Immediate functionalization and deposition of NPs overcomes agglomeration and surfactant issues while reducing public/worker exposure and environmental risks.

How is MBI contributing to the solution?

Novel approach: Figure 2 compares the NP morphology based on near room-temperature synthesis and deposition of ceria nanorods from a batch reactor and a microchannel mixer without the use of surfactants. Batch synthesis took several hours. Microchannel synthesis took seconds. Reaction concentrations and temperatures were identical. The NPs were deposited directly from the reactors.

Unique facility: The Oregon Process Innovation Center (OPIC) is a unique facility within the MBI for developing benchtop chemistries and demonstrating pilot-scale chemical process development and in-process characterization. Capabilities include in-process diagnostics and pilot deposition. NP characterization is greatly facilitated by the Linus Pauling Science Center at OSU and NIST-quiet ONAMI facilities at the University of Oregon.

Radical Abundance: How a Revolution in Nanotechnology Will Change Civilization | Kurzweil AI

Leave a comment


K. Eric Drexler is known as the founding father of nanotechnology—the science of engineering on a molecular level. In Radical Abundance, he shows how rapid scientific progress is about to change our world. Thanks to atomically precise manufacturing, we will soon have the power to produce radically more of what people want, and at a lower cost. The result will shake the very foundations of our economy and environment.

Already, scientists have constructed prototypes for circuit boards built of millions of precisely arranged atoms. The advent of this kind of atomic precision promises to change the way we make things—cleanly, inexpensively, and on a global scale. It allows us to imagine a world where solar arrays cost no more than cardboard and aluminum foil, and laptops cost about the same.

A provocative tour of cutting edge science and its implications by the field’s founder and master, Radical Abundance offers a mind-expanding vision of a world hurtling toward an unexpected future.

The topics include:

  • The nature of science and engineering, and the prospects for a deep transformation in the material basis of civilization.
  • Why all of this is surprisingly understandable.
  • A personal narrative of the emergence of the molecular nanotechnology concept and the turbulent history of progress and politics that followed
  • The quiet rise of macromolecular nanotechnologies, their power, and the rapidly advancing state of the art
  • Incremental paths toward advanced nanotechnologies, the inherent accelerators, and the institutional challenges
  • The technologies of radical abundance, what they are, and what they will enable
  • Disruptive solutions for problems of economic development, energy, resource depletion, and the environment
  • Potential pitfalls in competitive national strategies; shared interests in risk reduction and cooperative transition management
  • Steps toward changing the conversation about the future
