This chapter reveals the properties and general characteristics of the interstitial nitrides formed by the metals of Group IV (titanium, zirconium, and hafnium) and Group V (vanadium, niobium, and tantalum). These six nitrides are the only refractory transition-metal nitrides. They have similar ...
This chapter discusses the general characteristics of homolytic reactions and homolytic and heterolytic aromatic substitution. The term homolysis was first introduced by Ingold (1938), who drew a formal distinction between the two possible modes of bond-fission—heterolysis and homolysis. Although the ...
the easiest way to decide if a given unknown element is a metalloid is by testing whether any metal and non-metal characteristics can be detected. if both are detected, then the given element is most likely to be a metalloid element. q4 can mercury be classified as a metalloid? no, ...

During the last years, the scientific and industrial community has focused on the astonishing properties of Fe–Mn–Al–C steels. These high
Two-dimensional carbides and nitrides of transition metals, known as MXenes, are a fast-growing family of materials that have attracted attention as energy storage materials. MXenes are mainly prepared from Al-containing MAX phases (where A = Al) by Al dissolution in F-containing solution;...
the as-grown AMX2flakes exhibit unique electronic and ionic properties. A 10.4 nm AgCrS2flake shows superionic conductor characteristics at room temperature with an ionic conductivity of up to 192.8 mS/cm. The as-grown CuScS2flakes exhibit semiconductor ferroelectric properties, and show a Curie...
The most distinctive feature in IR spectra of these compounds 1–4 is that they all present similar characteristics in the Mo-O stretching region of 1000–700 cm−1 (Fig. S1 in SI). Take compound 1 as example (Fig. 6), the peaks located at 951, cm−1 are ascribed to the ...
the ceramic composite may include a first material that exhibits characteristics of a metal and a second material that exhibits characteristics of a dielectric. Generally, metallic materials are conductive and have overlapping conductance and valence bands in their electronic structure characteristics, wherea...
