According to a report from the Physicist Organization Network on January 22, researchers at the University of Buffalo in the United States have discovered that as long as water is added without heating, spherical silicon particles with a diameter of about 10 nanometers can produce hydrogen of high purity almost instantaneously, and it can be used as a portable device in the future. A potential source of energy supply for equipment.
In a series of experiments, the researchers created spherical silicon particles with a diameter of about 10 nanometers. When they react with water, they form silicic acid (non-toxic by-products) and hydrogen, which can be used as a fuel cell energy. Potential sources.
The reaction does not require any light, heat, or electrical energy. The rate of hydrogen generation is approximately 150 times faster than using 100-nm-wide silicon particles for similar reactions, and 1000 times faster for bulk silicon than similar reactions. The researchers stated that the difference is due to the geometry. When it reacts, larger particles form a non-spherical structure, and its surface does not react with water as stable and consistent as the smaller spherical particles.
Researchers say that when it comes to decomposing water to produce hydrogen, nanosilicon is better than many options that have been studied for a while, such as aluminum. With further development, this technology forms the basic principle of "adding water only" to produce the required hydrogen. The researchers verified that the purity of hydrogen produced by it is quite high, and it can successfully supply a small fuel cell for a fan. This most practical application will be the source of energy supply for portable devices.
Researchers say that the use of silicon, one of the most abundant substances on Earth, to rapidly produce hydrogen is unprecedented. Even though hydrogen is a good alternative to alternative energy sources, safe storage of hydrogen is a difficult problem. In practical applications, it will power hydrogen fuel cells and may be applied to military vehicles or other portable devices near water. Although a large amount of energy and resources are required to produce ultra-small silicon balls, these particles can provide useful, portable equipment where there is water. In some cases, such as in military operations and camping, the portable features are more important than the cost.
The researchers said that looking into future applications may not use gasoline or diesel generators, fuel tanks, or large-capacity battery packs, but instead use silicon nanopowder powders that are smaller and lighter than generators and some plastic ink cartridges. Activators can power satellite radio, telephones, GPS, laptops, lighting, etc., and even use the excess heat generated to boil water and make tea. (Hua Ling)
There are many types of composite lamps, each of which represents the unique cultural heritage and symbol of the Chinese nation.For example, the Lotus Combination Lamp symbolizes the tranquility and extraordinary of Oriental culture.The Phoenix Combination Lamp symbolizes good luck and eternal life;The Begonia Combination Lamp symbolizes that the national economy of our country is full of vitality and prosperity like spring.Auspicious Clouds Combination Lamp is a symbol of auspiciousness and exaltation.
All these kinds of combination lamps are to put the LED light source cleverly in the lamp, instead of the traditional sodium lamp and energy-saving lamp light source, in line with the modern road functional lighting demand.The lamp body USES LED light belt, which makes these combination lamps more vitality in the evening.
