The Japanese media reported on the 29th that the study found that the energy that the sun shines on the earth for a minute is enough for humans to use for one year. We all know that photosynthesis of plants can convert water and carbon dioxide into organic matter and oxygen. The surface of the earth is covered by water by 70%. The amount of carbon dioxide produced by humans is even more intensifying global warming. If we can combine solar energy, water, and carbon dioxide, we can With infinite resources being used effectively, the chemical raw materials needed by humans, such as methanol and ethylene, will also be inexhaustible.
This technology has already made great breakthrough in Japan at present, this is artificial light synthesis technology. It is understood that Japan’s Matsushita Corporation successfully used outdoor sunlight for the first time in December last year to successfully complete experiments and produced organic compounds formic acid; in May this year, the Central Research Institute under the Toyota Motor Group also used different methods and conditions to succeed outdoors. Artificial light synthesis experiments were completed and formic acid was also obtained.
Panasonic R&D said: “By improving the photosynthesis catalyst, organic substances such as ethanol, methanol, ethylene, and methane have been successfully produced. However, the amount of organic matter produced by the current experiment is relatively small, and the conversion efficiency of sunlight energy is only about 0.2%. The same, so the solar energy synthesis technology still needs further improvement, and strives to increase to 1% in 2016."
For this technology, the Nobel Prize-winning economist Nobuyuki Genkie also expressed his strong support. He believes: “For Japan, which lacks resources, we should strongly support the research and development of artificial light synthesis technology.†Prof. Kenji Uchiyama has already convinced The relevant cadres of the Ministry of Education, Culture, Sports, Science and Technology have already established artificial light synthesis technology as a national strategic project.
It is understood that in November last year, Japan’s Ministry of Economy, Trade and Industry made a joint decision with Japan’s Ministry of Education, Culture, Sports, Science and Technology, and plans to invest 15 billion yen (approximately RMB 900 million) in the next 10 years for the development of artificial light synthesis technology, striving to bring the sun to 2021. Light energy conversion efficiency increased to 10%.
The earliest introduction of the concept of artificially synthesized light technology was Professor Miyoshi Shinobu of Osaka City University. Professor Kamigami said: “According to the current progress, artificial light technology is still faced with many issues such as cost reduction and large-scale equipment development. In the future, we will develop new catalysts and strive to be practical in 2030.†Professor Kamiya also pointed out that it is not difficult to imagine that countries such as Europe, the United States, China, and South Korea will catch up with Japan in the field of artificial photosynthesis technology, but as long as Japan takes the lead in realizing it, This will ensure absolute superiority, which will also drive the Japanese energy revolution and economic growth.
Hexagon nuts (also known as finished hexagon nuts) are available in ASTM A563-A and are compatible with mild steel Bolts, such as ASTM A307, ASTM F1554 Grade 36, SAE Grade 2 and AASHTO M183. SAE Grade 5 and Grade 8 nuts are also available in finished style. Since hot-dip galvanizing usually increases the thickness of the threaded part of the fastener by 2.2 to 5 mils, the thread size of the galvanized hexagon nut is too large to compensate for the anti-corrosion coating on the bolt.
Chinese hex nut manufacturer Hongchuang Hardware provides hex nuts of various materials, such as carbon steel, stainless steel, alloy steel, titanium, etc.
