How to write the fourth grade content of nano-handwritten newspaper

The contents of the fourth grade of Nano Manuscript are as follows:

1. Nanotechnology is the abbreviation of nano-material technology, which refers to the free control of technology on atoms or molecules with a scale of (1 nanometer =1-9 meters), and the development of new materials or equipment with this scale.

2. Nanotechnology covers a wide range, including various technologies, such as using a brand-new method called molecular self-assembly to manufacture semiconductor devices, and developing new materials called nanoscale nanomaterials.

3. The static part of the new material and the stage of computer have been applied to the processor, but it is expected that the nano-scale robot and disposal by this technology will be used in buildings with self-proliferation ability.

3. Nanotechnology is considered as an area that will develop greatly in the 21st century.

4. There are also arguments about the future of nanotechnology. Although a variety of new materials and devices are expected to be useful in nanotechnology, the impact on the environment and human body has also attracted much attention.

5. People are also worried about the impact on the global economy and the danger that nano-machines will become uncontrollable.

6. The debate about whether it is necessary to formulate special regulations on nanotechnology continues.

7. There are several advantages in controlling materials at the nanometer level. For example, the size of transistors in electronic circuits currently used in computers and the like is about tens of nanometers, but if it can be reduced to 1/1, the computer will become smaller and necessary.

8. The generation of electricity and heat can be suppressed. Similarly, it is expected that storage devices and the like will be smaller and more functional.

9. When a substance is made into several nanometers, a special phenomenon called quantum effect will appear.

1. used in recent electronic equipment, the size of energy level dispersion and the distance of tunneling effect are in the nanometer range through the limitation of electrons. In addition to electronic materials, attempts have been made to develop medical applications, such as drug delivery systems.

11. The field of nano-materials includes research and material development. When it becomes nano, its unique properties are generated.

12. Colloids and surface chemistry are carbon nanotubes, such as fullerenes, various nanoparticles and nanorods, which provide valuable materials in nanotechnology.

13. Nano-scale materials are used for various purposes. At present, many commercialized nanotechnology is related to nanoscale materials.

14. The research is applying nano-materials to medicine (nano-medicine), and solar cells made of nano-materials are also used, and the conventional silicon is competing for solar cells and costs.

15. The semiconductor engineering technology developed for microprocessor manufacturing makes it possible to form structures below 1nm, and it has reached the level of nanotechnology. Giant magnetoresistance is made by hard disk atomic layer deposition (ALD), which can be said to be one of nanotechnology.
