SynopsisIn most cases, MOSFETs work in the saturation region. The state of working in the saturation region is usually called the static operating point. A small control signal perturbs vGS near this state, and the additional current associated with the drain is recor.....
SynopsisCompressed Air Foam System (CAFS) is a system for the production of high-quality CAF (Compressed Air Foam), which is used to fight solid and liquid fires. In the production of CAF, the same three components are required (water, foam compound and air) as in the.....
SynopsisForest fire trucks are firefighting vehicles designed for fires in forests and bush landscapes as well as terrain that is difficult to access. The global Forest Fire Truck market was valued at US$ 178.4 million in 2023 and is anticipated to reach US$ 272.....
SynopsisThe working principle of the detector is that the photons incident on the polycrystalline film will promote the electrons to pass through the band gap, thereby increasing the conductivity of the material, thereby reducing the resistance of the material. The po.....
SynopsisThe lens of the apochromatic objective lens is made of special glass or fluorite and other materials. This objective lens can not only correct the chromatic aberration of red, green and blue light, but also correct the spherical aberration of red and blue ligh.....
SynopsisMulti-element oxide nanoparticles are very important in many fields of materials science. Metal elements can form various oxides. These can also adopt many structural geometries with electronic structures, which can exhibit the characteristics of metals, semic.....
SynopsisRare earth oxides refer to 15 kinds of lanthanide oxides with atomic numbers 57 to 71 in the periodic table, and 17 kinds of oxides of scandium (Sc) and yttrium (Y), which are chemically similar to lanthanides. Rare earth elements are widely used in petroleum,.....
SynopsisRadio frequency (RF) is radio frequency current, which is an abbreviation of high-frequency alternating electromagnetic waves. For wireless communication systems, electromagnetic waves need to be radiated into and received from space. This process is achieved .....
SynopsisA digital isolator is used to get a digital signal across a galvanic isolation boundary. Automotive digital isolators can be used in the field of electric vehicles The global Automotive Digital Isolators market was valued at US$ 55 million in 2023 and is.....
SynopsisRhenium powder is a light gray metal powder composed of agglomerated single crystals. Rhenium metal powder is used in semi-finished products, such as anode plates used in medical applications. The global Rhenium Metal Powder market was valued at US$ mill.....
