50 . replace the following complex sentences or groups of sentences by simple sentences with the complex object. model: scientists found that materials displayed special properties at the nanoscale. scientists found materials to display special properties at the nanoscale. 1. people used nanoscale-based processes as far back as the middle ages. we know about it. 2. many researchers consider that the process of obtaining nanocrystals is very slow and complicated. 3. it would be really exciting to watch how atoms assemble themselves into nanostructures. 4. students cannot experiment with nanotubes. the head of the laboratory has forbidden it. 5. no one had expected that the developments of nanotechnology would be used in such everyday products as sunscreens. 6. the nanostructures are self-replicating. i would like to see it.
