English: Title-Author-Publication Information (Edition, Publisher, Publication Date)
The book says 1. Nanomaterials.
(1) The surface of the washing machine barrel can be treated with nanotechnology to release bacteria.
(2) The surface of the tie is treated by nanotechnology, which is waterproof and oil-proof.
(3) The ceramics made of nano-ceramic powder have toughness, and the engine can improve its performance.
2. "Green" energy
(1) Although the dry battery is light, it can only be used once, and it pollutes the environment. Lead batteries are too heavy and lithium batteries have low density, so they are small in size, light in weight, rechargeable for many times and have little environmental pollution.
(2) Silicon photovoltaic cells can convert solar energy into electric energy and can be used in artificial satellites.
3. Memory alloy
The main components of (1) memory alloy are nickel and titanium. Memory alloy has unique physical characteristics: when the temperature reaches a certain value, the crystal structure inside the material will change.
(2) Memory alloy can be used for surgery and can also be installed in the outlet valve of water heater to prevent burns.
