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 effect of water-reducing agent. When dealing with different types of "problem" cements,…
In the UK, more than 100 schools were closed because of the danger of collapse In the UK, many schools use RAAC (autoclaved aerated cement) This is a concrete material that is lighter. In 2018, the roof of a school in southeast England fell down…
Boron has been a major name in the world of chemistry. There have been two Nobel Prizes in Chemistry for the work done on boron. There are a few heat-resistant products on the market that have boric acid added to the glass. This means the glass wi…
What is tungsten Oxide?Tungsten dioxide has the molecular formula WO3 with a weight of 2318.5. It is a form of tungsticanhydride. Tungsten dioxide is not produced in industrial production. The tungsten-trioxide salts are classified according to thei…
In recent years, transition metal dichalcogenide was one of the key two-dimensional quantum functional material in the world. These materials have a honeycomb like graphene but have spin-orbit coupling that allows them to exhibit novel properties. As…
GaN-based chargers have been introduced to the market. These chargers provide a high amount of power for the device, while still maintaining a size that is reasonable, and even take up less space than the traditional chargers. Gallium Nitride, or GaN…
Is boron a metal?Boron powder does not belong to the metal family, and it is a solid that lacks many of the metal's characteristics. Boron has the lowest outermost electron count of any non-metallic. It is available in both amorphous (either a brown-…
At the moment, there is a view that graphene's ongoing fever in China is overdone.In the view of zhao meng, deputy secretary general of the China international graphene industrial resources alliance, the market decides whether graphene should continu…
Modern industry cannot function without ultrafine alumina. Alumina powders with ultrafine or fine grain have a different surface electronic structure, and crystal structure, which results in surface effects, and smaller sizes, that cannot be found in…
British media have reported that scientists made a major discovery - the conversion from radio signals to electricity. Popularly speaking, this is power generation via WiFi! We may see battery-free phones and battery-free laptops in the future. MoS2…
What is Hafnium Carbide and Tantalum Carbide? Tantalum carbide is a brown powdered metal cubic of the sodium chloride system. The tantalum carbide used today is a sintered cemented carbide grain growth inhibitor. This has an important effect in suppr…
In the absence of new countries to replace China's declining aluminum demand, the era high profits is expected for the alumina industries. Only the complete utilization of red clay, also known as the global problem, can be expected to bring the bann…
Octadecylamine ethoxylate ether, also known as Polyoxyethylene stearamide, colorless to yellow solid, insoluble in water to soluble in water, soluble in acetone, benzene and other organic solvents, with excellent emulsification,dispersion, solubiliza…
C10 alkyl glucosides can be neutral, aqueous or slightly alkaline. Viscous, light yellow liquid at room temperatures. C10 Alkylglucoside is a good example: C10 alkyl glucosides can be neutral, aqueous or slightly alkaline. It is a light yellow vis…
The titanium hydride used as a getter is also used to make metal foams, as well as to provide high-purity hydrogen. It can also be found in powder metallurgy and metal-ceramic sealing to supply the alloy powder with titanium. Titanium Hydride is b…
