Interfacial Mo, W-Conjugated Polarization, and Oxygen Vacancies of MoO2/WO3 in Enhanced Microwave Therapy for MRSA-Induced Osteomyelitis

“…As a type of electromagnetic spectrum, MWs can cause the oscillating friction of ions and polar molecules in cells billions of times per second, which results in rapid heat generation. − The most prominent characteristics of MW-absorbing materials are excellent impedance matching and strong dielectric loss capability . Recently, transition metal oxides, such as common semiconductor materials with excellent dielectric properties, have attracted much attention in the fields of catalysis, electrochemistry, supercapacitors, and microwave absorption, involving ZnO, Co 3 O 4 , CuO, MnO 2 , MoO 2 , MoO 3 , etc. − In particular, the transition metal oxides of MoO 2 and WO 3 have high metal conductivity and good chemical and thermal stability. − The Mo coordination of monoclinic MoO 2 does not follow a strict octahedral form, and there are two types of different Mo–O bonds and nonpolar Mo–Mo bonds that result in metal conductivity . Because of its electrical conductivity, the surface of MoO 2 has a mass of free electrons, thus exhibiting a strong localized surface plasmon resonance effect (LSPR) under irradiation. , The monoclinic WO 3 has similar properties.…”

Fe–Co coatings electrodeposited from eutectic mixture of choline chloride-urea: Physical characterizations and evaluation as electrocatalysts for the hydrogen evolution reaction

“…Among these materials, the FeeCo alloys stand out for having important properties such as high Curie temperature, high permeability, low hysteresis loss, excellent thermal stability [6e8], and high anisotropy energy [9,10]. All these characteristics allow the FeeCo coatings to have a wide variety of technological applications that cover different areas of knowledge, for instance, microwave absorption [11], high-density data storage [12], magnetic resonance imaging [13], micro-inductors [14,15], drug delivery [16], and electrocatalysis [17].…”

The optic and dielectric properties of CuO deposited barite pigments

“…However, the nuclear energy applications, oil transportation lead to environmental pollution. Herein, CuO has attracted more attention for communication, microwave absorbers, heating or cooling systems [4].…”

“…Moreover, CuO can be used for dual coating process due to interacting with other oxides. Wan, Y., et al have dual coated CuO and FeCo deposited carbon fibers with facile electrodeposition and oxidization methods [7]. Jun and Xu, has synthesized CuO/Co/Carbon fiber by using twice electroless plating for microwave absorption application [8] In addition that Barite (BaSO4) is a most important candidate for the oil and gas industry [9].…”
