What are surfactants, and how do they work? Surfactants belong to a class that reduces surface tension. They can be adsorbed onto gas-liquid or fluid-liquid interfaces and change the properties, such as stability, wettability (wettability), viscosity…
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…
The titanium hydride used in powder metallurgy and metal-ceramic sealing is also used to provide titanium for the alloy powder. Titanium Hydride is very fragile and can be used for powdered titanium. The hydride is also used to weld. Thermal decom…
Boron carbide is also known as black Diamond. It has a molecular formula of B4C. The powder is typically grayish. It is one the three hardest materials known (the other two being diamond and cubic boronnitride), which are used in many industrial appl…
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…
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…
What is aluminium nitride (AlN)?Aluminum nitride (a covalent-bond compound) is an atomic-crystal belonging to a diamondlike nitride. It has hexagonal crystals, a wurtzite structure, and is non-toxic. Aluminum nitride formula AlN. Aluminum nitride, wh…
GaN is a semiconductor material of third-generation with a large forbidden-band width. It has superior properties compared to first-generation Si, and second-generation GaAs. GaN devices, due to the large band gaps and high thermal conductivity of G…
