This article gives you a detailed understanding of the difference between P-type bismuth telluride and N-type bismuth telluride
What is Titanium dioxide?Titanium dioxide (TiO2) is a fine white powder or dust that occurs naturally. It was first intentionally produced for use as a white pigment in 1923. It is naturally opaque and bright, which makes it useful for use in paper, ceramics, rubber, textiles, paints, inks, and cosmetics. Titanium dioxide is also a UV filter and an effective active ingredient in sunscreens. Exposure can irritate the eyes, nose, and throat since it has been shown to cause lung cancer in animals.
What is Fe3O4?Fe3O4 nanoparticles have unique properties, including magnetic properties, large surface area, and low toxicity. Natural iron sand is a natural resource that has iron oxide compounds. Then, we will highlight the use of Fe3O4-based NPs in emerging applications, such as biomedical applications (hyperthermia, MRI contrast agents, and drug delivery), biosensing, environmental applications for removing heavy metals and organic pollutants, and energy storage devices. The one-step reactio
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 instead of a set temperature.Material: nylons, fibers and nylonsSLM Metal 3D PrintingMetal sintering can be described as a selective laser sintering. It is the process of using a powder stick to spread a layer on molded surfaces, then heating to a te
What is Wear resistant alumina ceramic lining (Alumina Ceramic Lining)?The wear-resistant alumina lining is made from a corundum special ceramic, which is formed using Al2O3 (as the main raw material) and a rare metallic oxide as a solvent. This ceramic was then calcined in high temperatures of 1700°C.There are many different types of alumina tiles that can be used as wear-resistant ceramic linings. These include alumina sheets, high aluminum linings (also known as wear-resistant ceramics), alum
The graphite world demand has increased steadily in recent years due to the global economic recovery. USGS reports that the primary countries producing graphite in the world include China, India Brazil Canada North Korea Russia Czech Republic. As heating and acid leaching technologies improve, graphite purity is rising, allowing for new high-tech applications. With the advent of purification technologies, graphite is now widely used for carbon composite materials, electronic industry, friction m
What is Silicon powder?Silicon powder, known as micronized silicon, is used for many applications. Metallurgical silicon is typically produced in a size of 0-100 mm, but further size reduction is required for most applications. The optimum particle size depends strongly on the final application. This means that, in many cases, some optimization work is needed to find the most cost-competitive solution. Silicon powder is produced by crushing, milling and classifying silicon material to obtain the
What is Foamed Concrete?EABASSOC Foaming Agent is a highly concentrated, highly efficient liquid that produces EABASSOC Lightweight Foamed Concrete. In this study, it was concluded that foam concrete prepared by mixing cement 60 and 40% with detergent of 0.4% by weight of cement be the best possible mix out of the selected mix ratios without compromising the engineering properties of concrete. The role of foaming agents in cellular concrete is to create small and enclosed air bubbles by reducing
You can charge a metal sphere without touching it by connecting it to the earth with a wire. The electrons can flow to the bottom whereas the positive charges at the close to finish can stay command there thanks to the attraction of the negative charges on the rod. The magnetic field within the hollow sphere of the ferromagnetic substance is zero. Magneto static shielding means to shield any specimen from magnetic effects by placing it within a hollow region of a ferromagnetic substance. The vol
Saturated Silica Gel can be reactivated by placing it in an oven at 150°C (300°F) for up to 3 ½ hours or until the blue color is restored; note: heating above 162°C (325°F) can damage the gel and render it unable to absorb moisture. Silica Dust will float in the air for up to 12 days, give or take. The particles are very tiny. One spec of silica dust is almost 100 times smaller than a single grain of sand. Due to its size, silica dust stays suspended in the air longer than other dust particles.
Breathing in dust from silica-containing materials can lead to Silicosis. Silica dust particles become trapped in lung tissue, causing inflammation and scarring. The particles also reduce the lungs' ability to take in oxygen. Many products use fumed silica (silicon dioxide) as a filler or flow control additive. Many other metal oxides including TiO2, ZnO, and Fe2O3 are produced as particulate solids with a primary particle size below 100 nm. Fumed silica powder has a high surface area. It is ext
How to make Quartz shiny? To give your quartz countertop its old shine back, mix 1 part vinegar and three parts water. With the help of a spray bottle and a microfiber cloth, spray the mixture on the countertop and polish it until you get the shine you want. Quartz is primarily quartzite, but other natural minerals are added to create unique patterns. Sparkle quartz countertops are achieved by adding mirror chips during the fabrication process. Stick to just plain baby wipes for the best results
Regarding the unique electrical and conductive properties, antimony tin oxide (ATO) nanoparticles have been used extensively as transparent electrodes and thin films, support material for electrocatalysis, energy storage devices, gas sensors, and photo electrocatalysis. It has been employed as a supporting agent in composite materials, radioactive waste management, and optoelectronics. The antimony-doped tin oxide nanoparticles have also found broad applications in solar cells and heat-reflectiv
So far, there are rumors that the Pro version of the iPhone 14 will be equipped with an unnotched display and a 48-megapixel camera. However, we have to wait to see if this will become a reality. However, rumors about the iPhone release dat
Thermal properties of foam concrete can be improved by several types of additives, i.e., coir fiber, which applied resulted in higher heat capacity and lower thermal conductivity of the FC, as well as polypropylene fibers, which allowed for the reduction in the thermal conductivity and improved the mechanical properties of foam concrete. Moreover, the degree of thermal insulation in FC might be influenced by the mixture composition, such as aggregate type and mineral admixtures. Next, conductivi
