Concrete, an ordinary building material, has profound effects on our daily lives. Concrete is widely used for a variety of buildings and projects - from skyscrapers and bridges to roads and public facilities, to home improvement. Technically, it is d…
In the UK, more than 100 schools were closed because of the danger of collapse In the UK, many schools use Autoclaved aerated cement (RAAC). This is a concrete material that is lighter. In 2018, the roof of a school in southeast England fell dow…
The water-reducing agent should be used with concrete admixture, which will reflect the water-reducing effect. Cement quality is therefore a direct factor of the actual effect of water-reducing agent. When dealing with different "problem" types of ce…
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 added boric acids to common glass. This means the glas…
In recent years, transition metal dichalcogenide was one of the key two-dimensional materials for quantum functional applications. These materials have a honeycomb like graphene but have spin-orbit coupling that allows them to exhibit novel propertie…
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…
What is Hafnium Carbide and Tantalum Carbide? Tantalum carbide is a brown powdered metal cubic crystal belonging to the sodium-chloride cubic system. The tantalum carbide used today is a sintered cemented carbide grain growth inhibitor. This has an i…
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…
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 crystalline and amorphous…
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 a crystal structure that is not present in macroscopic objects. This has led to surface effects…
British media have reported that scientists made a major discovery - the conversion from radio signals into electricity. Popularly speaking, this is power generation via WiFi! We may see battery-free phones and battery-free laptops in the future. Mo…
Foam concrete contains a large number of closed pores, the air in the pores is a good adiabatic medium, which can cut off the heat exchange.…
The organic compound Sorbitan Monolaurate is miscible in organic solvents, oils and oils About Sorbitan monolaurate: The sorbitan monolaurate miscibles with oils, organic solvents to form a water-based semi-emulsion. Dehydration of sorbitol is for…
The roble had hit a record low after the West imposed sweeping sanctions on Russia for its aggression in Ukraine. Russia's president recently ordered exports of Russian gas to "unfriendly" countries to be settled in robles. The speaker of Russia's up…
