However, our knowledge of the global nitrogen cycle was limited until the discovery of an alternative anoxic process that involves the use of redox metals as catalysts. For example, the anoxic marine sediments comprise different microbial communities that depend on metal oxides/oxyhydroxides of Fe (...
Oxidesare compounds (and, of course, pure ones). There are only two elements in its composition, one of which must be oxygen element, the other is called metaloxideif it is a metallic element, and nonmetallic oxide if the other is not metallic element. In a broad sense, oxide refers to...
Atomically thin metal oxides have attracted attention recently because of their unique electronic, optical and magnetic properties that are rarely found in their bulk counterparts18,19. By adopting simple oxidation, a stable, stoichiometric and atomically thin oxide layer can be formed on the metal su...
It is known that oxygen vacancies affect the electronic structures and transport properties in bulk transition-metal oxides30,31. In particular, oxygen vacancies have been shown to induce MIT in LaNiO320,24,28. It was suggested that oxygen vacancies lead to an increase in the Ni2+/Ni3+ ...
Metal oxides are widely used in many applications such as thermoelectric, solar cells, sensors, transistors, and optoelectronic devices due to their outstanding mechanical, chemical, electrical, and optical properties. For instance, their high Seebeck coefficient, high thermal stability, and earth abundan...
Metal oxides nanoparticles are another branch of nanoparticles that can be directly made by LA and they are frequently synthesized and intensively studied. A wide range of metal oxide nanoparticles have been synthesized using metal targets including iron (Fe) [52, 53], aluminum (Al) [54], titan...
Transition-metal oxides improve power conversion efficiencies in organic photovoltaics and are used as low-resistance contacts in organic light-emitting diodes and organic thin-film transistors. What makes metal oxides useful in these technologies is the fact that their chemical and electronic properties ...
The subjects covered in the book can be divided into three sections. The first (chapters 1 to 3) covers the structural, physical, magnetic, and electronic properties of transition metal oxides. Although the emphasis is on surface properties, relevant bulk properties are also discussed. The second...

Recent studies have been focused on the toxicological effects of a wide variety of ENPs using different validated biological models. This literature review emphasizes the study of toxicological effects related to using the most common ENPs, specifically metal and metal/oxides-based nanoparticles, ...
