This article gives you a detailed understanding of the difference between P-type bismuth telluride and N-type bismuth telluride
This work reports on investigating nanosized CeO2-ZnO systems prepared by Pechini's method. The structural and morphological characterization of CeO2-ZnO systems as well as the characterization of CeO2 and ZnO separately, showed that the employed method resulted in powders with spheroidal particles whose sizes are in the range of 30 - 200 nm, which is appropriate to provide homogeneous suspensions. The ZnO present in the prepared mixed oxides seems to increase particle size distribution and infl
What is CeO2?Nanocrystalline cerium(IV) oxide (CeO2) powders were prepared by heating solutions of cerium(IV) salts in the presence of urea under hydrothermal conditions at 120° to 180°C. The effects of urea concentration and hydrothermal treatment temperature on the morphology and crystallite size of the synthesized particles were investigated. The synthesized particles were angular, ultrafine CeO2 with a cubic fluorite structure. Their crystallite size decreased from 20 to 10 nm with increasin
What is Molybdenum disulfide?Molybdenum disulfide (MoS2) is an inorganic metallic compound composed of molybdenum and sulfur. It occurs naturally as the mineral molybdenite, the principal ore of molybdenum. This compound is silvery black in appearance and is relatively unreactive with other chemical elements. In terms of appearance and texture, molybdenum disulfide is similar to graphite. Like graphite, molybdenum disulfide is renowned for its low coefficient of friction, durability, and robustn
The bane of all ceramic materials is that a particular measured property value for a particular specimen may depend on a particular feature of the particular microstructure of that particular specimen. In the absence of tightly controlled processing procedures, the best that one can do as a means of generically characterizing such a material is to establish trends of values that correlate with changes in the microstructure and composition. Given such trends, it should then be possible to interpo
Recently, some countries are short of electricity, or seek energy solutions, will this affect the all about bhutan ?
This week, a new cross-blockchain bridge connecting the Ethereum network and Dfinitys Internet computer will allow ERC-20 tokens to exist natively on Dfinitys network, the developer behind the bridge said. The Internet computer is a blockch
Valve has again revealed this years highest-grossing games on Steam. The sixth annual Top Grossing Games list divides the top 100 games into several categories, with games in each category ranked randomly. In the platinum category, 12 games
This year, Apple introduced the iPhone 13 series. These devices are still new, but weve already seen rumors and leaks about next years iPhone 14 line. Today, as the first reports of the iPhone 15 begin to emerge, we get a closer look at the
This stylish flip phone comes with a small external notification window, some interesting camera technology, and a flush fold. Although until recently, the P50 Pocket may have been regarded as a rival of the Galaxy Flip 3, Samsung can relax
The Internet Association, an organization in Washington that claims to be the unifying voice of the Internet industry, will be closed at the end of this year. Before this, companies such as Microsoft and Uber canceled financial support for
Earlier this month, we saw a leaked Google Pixel Watch marketing image, which showed a round watch body and a low-key, round-edged touch screen. A recent report from Google 9to5Google mentioned PIXEL_EXPERIENCE_WATCH, which not only strengt
Since the birth of quantum mechanics quantum entanglement is one of the most representative concepts. After some initial treatment two or more particles can enter a state of seemingly "hyperspace correlation": even if they are separated by h
The iron oxide core is encapsulated in an inorganic or organic coating for particle stabilization and biocompatibility. The iron oxide particle could be located not exactly at the center of the coating material but rather peripherally and is also known as the York structure. On the contrary, the inverse core-shell structure is characterized by an iron oxide coating of nonmagnetic functional material. In addition, the combination of one or more functional materials and further coating of already
Sodium ion battery is a kind of secondary battery (rechargeable battery), which mainly relies on the movement of sodium ions between the positive and negative electrodes to work, similar to the working principle of lithium ion batteries.
