The wide-gap semiconductor material GaN is widely used due to its excellent electrical, optical and physical properties. 1.Semiconductor light Gallium Nitride is widely used in semiconductor lighting. The high luminescence and high reflectivity of gallium nitride material make it ideal for high-performance, LED lamps. LED lamps offer a higher level of luminous efficiency than fluorescent…
A detailed introduction to surfactants
What are surfactants, and how do they work? Surfactants belong to a group that lowers the surface tension on a liquid. They can be adsorb on interfaces such as gas-liquids or liquids-liquids. By doing so, they change the properties and affect the stability, wettability of the interfaces. Surfactants can be found in many fields including…
More than a hundred schools in the UK have been closed due to the risk of collapse
In the UK, more than 100 schools were closed because of the danger of collapse In the UK, many schools use Aerated concrete autoclaved (RAAC). This is a concrete material that is lighter. In 2018, the roof of a school in southeast England collapsed. It was later discovered that RAAC had been used for the…

Water-reducing agent solution for these three
The water-reducing agent should be used with concrete admixture, which will reflect the water reduction effect. Cement quality is therefore a direct factor of the actual effect of water-reducing agent. When dealing with different types of “problem” cements, different strategies are required. High alkali cement High-alkali is a cement type with a large amount of…
What is Lithium stearate powder
Lithium stearate is a crystalline form of lithium. Lithium stearate has the chemical formula LiSt. It is a white powder that is solid at room temperatures. It is highly lipophilic, and at low concentrations can produce high light transmission. This compound is only slightly soluble when heated to room temperature, but it dissolves readily in…
CLC blocks and foamed concrete lead the reform of the construction industry
CLC Blocks and foamed Concrete, two new energy-saving materials, are leading the way to a greener construction industry. As environmental awareness continues to improve, the construction industry is now focusing on more energy-efficient and environmentally friendly building materials. The construction industry has been gradually adopting CLC block as an environmentally friendly, energy efficient, and durable…
Why does properly poured concrete end up cracking
It is very easy to cause concrete cracking if the construction or maintenance are not done correctly. What are then the five main causes of cracking concrete? 1. The cement proportion problem: Some workers in construction will add more water for a more fluid concrete. However, this will result in an increase in water-cement ratio….
What is Molybdenum disulfide MoS2 powder
Description of Molybdenum diulfide Molybdenum disulfide (also known as MoS2) is a transition metal sulfide. It is dark grey, or black solid. The layers of the crystal structure are made up of alternate arrangements of sulfur and Molybdenum. Molybdenum disulfide This material is a good choice for its chemical and thermal resistance. It can be…
