判断题

Nanoscience and nanotechnology involve the ability to see and to control individual atoms and molecules. Everything on the Earth is made up of atoms—the food we eat, the clothes we wear, the buildings and houses we live in, and our own bodies.

A. 对
B. 错

判断题

Nanoscience and nanotechnology are the study and application of extremely large things and can be used across all the other science fields, such as chemistry, biology, physics, materials science, and engineering.

A. 对
B. 错

判断题

Some researchers believe nanotechnology can be used to significantly extend the human lifespan or produce replicator-like devices that can create almost anything from simple raw materials. Others see nanotechnology only as a tool to help us do what we do now, but faster or better.

A. 对
B. 错

判断题

Many fields of endeavor contribute to nanotechnology, including molecular physics, materials science, chemistry, biology, computer science, electrical engineering, and mechanical engineering.

A. 对
B. 错

判断题

National Science Foundation of the US says: nanotechnology is "Research and technology development at the atomic, molecular or macromolecular levels, in the length scale of approximately 1 – 500 nm range."

A. 对
B. 错

判断题

Advances in nanoscience are making it impossible to create innovations such as ultra-small camera lenses, toxin-hungry nanosponges, and advanced drug therapies. Nanoscience can be applied across all the science fields, such as chemistry, biology, physics, materials science, and engineering.

A. 对
B. 错

判断题

Unbound engineered nanoparticles are engineered nanomaterials that, under normal temperature and pressure conditions, are contained within a matrix that would reasonably be expected to prevent the particles from being separately mobile and a potential source of exposure.

A. 对
B. 错

判断题

In 1887, Michael Faraday discovered colloidal "ruby" gold, demonstrating that nanostructured gold under certain lighting conditions produced different-colored solutions.

A. 对
B. 错

判断题

In 1957, John Bardeen, William Shockley, and Walter Brattain at Bell Labs discovered the semiconductor transistor and greatly expanded scientific knowledge of semiconductor interfaces, laying the foundation for electronic devices and the Information Age.

A. 对
B. 错

判断题

In 1984, Tokyo Science University Professor Norio Taniguchi coined the term 'nanotechnology' to describe precision machining of materials to within atomic-scale dimensional tolerances.

A. 对
B. 错
