Let's practice identifying the nature of metal oxides and non metal oxides. Electrolytic Reduction . A desire to overcome these restrictions has given impetus to researchers to focus on searching for new gas sensing materials and emerging technologies in the field of textile-based gas sensors. Electrodeposition. Metal oxides are crystalline solids that contain a metal cation and an oxide anion. Earlier research in the field was devoted to bulk metal oxides before interest developed in their thin films aspect. CNT/polymer nanocomposite materials have received special attention from researchers worldwide, as it can operate at room temperature, low power consumption requirements, and offer several design possibilities with the e-textiles.40 In addition, CNT/polymer nanocomposite materials are also investigated as alternative gas sensing materials for several applications such as healthcare,41 agriculture,42 industry,43 and environment.44–46 Recently, researchers have developed a wearable smart technology to change both a design and a fabrication process by using electronic circuit and digital components embedded in clothing known as e-textile or electronic textile. While metal oxides are solids at room temperature, gaseous oxides also form. When they are reacted with water, acids are obtained. These compounds are very important in biochemistry . In this case, the CNT is functionalized by attaching MOX nanoparticles, either by bonded or nonbonded interaction, onto the sidewall of the CNT.32,33 The most common method for achieving strong interaction of MOX nanoparticles on the CNT is to oxidize CNTs by strong acids to introduce carboxyl or hydroxyl groups on the CNT surface. This is useful for controlling how much electric current travels to certain parts of electronic devices. According to this behavior, they react with acids in typical acid-base reactions to produce salts and … Despite the simple working principles of MOX gas sensors, the gas sensing mechanism at the microscopic level is very complex and is still not adequately understood.18,19 Gas sensors made of the same MOX materials can have different properties depending on the fabrication techniques and preparation conditions. However, MOXs have certain disadvantages that limit their applicability in many areas, such as in mobile devices where energy consumption is a major concern. What does MOM stand for? The word varistor is short for variable resistor. NH4OSbW An example of a commercially available MOS sensor is the AirBase CanarIT; the sensor enhances commercial MOS gas sensors that operate in a plug and play mode to sample every 20 seconds. Siva Prasanna, ... Sravendra Rana, in Nanomaterials and Polymer Nanocomposites, 2019. Metal oxides have a wide range of applications, and they can be prepared by a wide variety of methods, such as the following: High-temperature solid-state (ceramic) method. The second word is the root of oxygen plus the suffix "–ide" METAL(N) oxide The novel physical effects in metal oxide nanostructures could be used for the development of sensor tool with advanced parameters. That is to say, they are formed by an oxygen atom (O) with valence -2 and an atom of any metallic element . The recent progress and advances in metal oxide-based polymeric nanocomposites, including their preparation using different techniques, has also been explored. It is also known as alumina, and exists naturally as corundum or bauxite. There are two general statements that describe the behaviour of acidic oxides. The layer of metal oxide reflects the sun and reduces the level of visible light. Tailoring of the surface properties of metal oxide allows improving sensitive properties. Roman Viter, Igor Iatsunskyi, in Nanomaterials Design for Sensing Applications, 2019. The advent of chemical gas sensors and the electronic nose (e-nose) in the 1990s4,5 has opened new opportunities for applications in many areas never seen before, especially for real-time, on-site, and rapid measurements. The term MOV or Metal Oxide Varistor is a variable resistor. In fact, the surface of metal oxides is a key factor for effective interaction with target molecules. Ternary metal oxides (TMOs) have become a new class of electrode materials for supercapacitors because of their excellent electrochemical performances. Yuping Wu, Teunis van Ree, in Metal Oxides in Energy Technologies, 2018. The resistance of the MOV can be varied to protect the power supply circuit from spikes due to high voltage. Metal-oxide-semiconductor-field-effect-transistors (MOSFETS) are the most widely utilized semiconductor transistors in contemporary technology. Rongming Wang, Jian Wu, in Metal Oxides in Supercapacitors, 2017. In addition, they are presented in the three, Metal oxides, as we have said before, are obtained when, . It is firmly believed that catalytic reduction/oxidation at the microscopic surface underlies the chemoresistive property of MOXs.20 These reactions are governed by the electronic structure, chemical composition, crystal structure, and relative orientation of the oxide surface to the analyte molecules, thereby allowing their gas sensing properties to be tuned by modifying such parameters. In addition, they are the raw material in chemical laboratories to obtain bases and other compounds , since their abundance makes them much easier to obtain and handle. Then, the researchers try to figure out the appropriate method to merge electronics with clothing and jewelry. Among metal oxides, cobalt oxide (Co3O4), cupric oxide (CuO) and zinc oxide (ZnO) have been studied in current research. Metal oxides thus typically contain an anion of oxygen in the oxidation state of −2. Metal oxides are considered the most vital class of materials from both a technological and a scientific approach. An insoluble metal oxide is formed by chemical reaction between different solutions [12, 13]. For example, zinc oxide sintered together with other metal oxide additives have been made into nonlinear resistors, which are called Varistors for surge suppressing function. For example, researches from NC STATE UNIVERSITY College of Textiles have demonstrated that the development of lithium-ion battery provides better performance by using MnOx/C nanofibers instead of graphite in the anode of the battery, called 18650 cells.57 An interesting smart textile project, the ProeTEX (PROtection E-TEXtiles), is the research cooperation of European countries which gives greater importance to the development of e-textile-based MicroNano technology and wearable system for rescue workers and firemen.58,59 Recent research in electronic textile technology field has found out that the key component of this technology is the electronic circuit part on textile for controlling and processing equipment.
