Modern industry cannot function without ultrafine alumina. Alumina powders with ultrafine or fine-grained grains have a surface electronic and crystal structure that is different from macroscopic objects. This leads to surface effects, small sizes, a…
British media have reported that scientists made a major discovery - converting radio waves into electricity. This is commonly referred to as power generation via WiFi! We may see battery-free phones and battery-free laptops in the future. MoS2, a n…
What is Hafnium Carbide and Tantalum Carbide? Tantalum carbide is a brown powder of metal cubic crystals that belongs to the cubic sodium chloride system. The tantalum carbide used today is a sintered cemented carbide grain growth inhibitor. This has…
Flexible electronics can benefit from ultra-thin materials of atomic thickness, which are used for manufacturing microprocessors. Recent breakthroughs have been made in this area by researchers at the Vienna University of Technology, Vienna, and the…
GaN is a semiconductor material of third generation with a large forbidden-band width. It has superior properties compared to first-generation Si or second-generation GaAs. GaN devices, due to their high thermal conductivity and large band gaps, can…
What is aluminium nitride (AlN)?Aluminum nitride (a covalent-bond compound) is a white, grayish, or white-grayish atomic crystal that belongs to a diamond like nitride. Aluminum nitride formula AlN. Aluminum nitride, which is metal-treated, can repla…
SLS Nylon Powder PrintingNylon sintering (selective laser sintering) is a project that uses spread powder sticks to tile a thick layer of powder materials, such as 3D printed metal powders, on parts. It is heated below the powder melting temperature…
What is Alumina? Alumina. Chemical formula Al2O3. The ionic crystals are used to manufacture refractory materials. They have a melting and boiling point at high temperatures of 2054 deg C. Diaspore and bauxite are used as raw materials to make ind…
Alumina fibres have a lower thermal conductivity and heat capacity. The temperature of long-term usage is higher than that of ordinary aluminum silicate (1000 1100 degC). It can be used with acidic atmospheres, oxidizing atmospherics, reducing atmosp…
US nanotechnology plan for research and development The US investment is equivalent to the amount invested by Japan and EU countries in the research and development of Nanotechnology. This field is equivalent to the investment of Japan and EU countri…
The market expectation is that the building curtain wall will be the result of the building technology. It is an integration of the building technology and architectural art. Due to their outstanding resistance to fading corrosion UV, cracking weathe…
Introduction to explosive compoundsExplosive compounds, attired metals (additionally referred to as explosive welding), were uncovered by a little blessing: in 1944, the American L.R. Carl, in an explosive explosion examination, unintentionally disco…
