Scientists at NUST MISIS (Moscow State University of Science and Technology) at the National Research Technology University of Russia used the self-propagating high-temperature synthesis (SHS) method in "solution combustion" to develop nanomaterials with special properties. These materials can be widely used in fuels, solar cells, new-generation capacitors and energy storage devices, and new catalysts. The team led by Prof. Alexander Mukathyan put the mixture of nickel nitrate and glycine in a high-porosity environment to allow them to react and obtain a catalyst that will not attenuate or be contaminated. The new catalyst can be used dozens of times more than normal catalysts. This method has now been patented. This catalyst is used in automobiles to reduce the emission of harmful substances. In the past 10 years, nanotechnology has been booming, and nanomaterials are expected to be “excellent†in electronics, medicine, construction, military, and agriculture due to their unique properties, but to develop materials with specific nanometer dimensions (such as magnetic requirements of less than 10 nanometers). Requires specialized complex equipment and high energy consumption. In view of this, scientists are actively investigating new methods for synthesizing nanomaterials - self-propagating high-temperature synthesis in solution or "solution combustion", that is, containing oxidants (nitrates) and reducing agents (solvents dissolved in water. The ingredients of amines, acids and amino acids interact to maintain an exothermic reaction (burning). In solution, the chemical reaction strongly expands until it disappears, forming the final nano product. The process of burning and synthesis of materials has always been the focus of scientists. In 1967, a team led by Soviet scientist Alexander Merzhov discovered the process of combustion without the use of oxygen and oxides—self-propagating high-temperature synthesis. In the 1990s, the team led by Prof. Krishnar Patil of India discovered the “variation†of this method—the self-propagating high-temperature synthesis method in solution. They used nitrate as the basis and added organic Combustibles glycine, sucrose, citric acid or urea, nanomaterials were obtained.
In recent years, electric bicycles, bicycle theft was rampant, most people have had stolen the experience distressing, but also to the security services helpless. Lock was added handfuls, but this car is a car and a lost, really hard to detect. Anti-theft alarm lock available, completely changed this phenomenon, alarm lock and alarm as a whole, there are both locked car alarm function, multi-function alarm lock applies to vehicles, doors, windows and other protection, so long as to come a little touch burglar alarm lock, That alarm will sound, the sound loud, so thieves can not start.
