theαparticle (Z = N = 2) forms a building block, and some nuclei can be composed ofαparticles. In such cases,Z = N = 2iholds withibeing an integer, and the mass numberA = Z + Nbecomes equal to ...
Located right above the Englishname for each element, the largest letters represent itschemical abbreviation. The largest number is the element’satomic number. Other information in the box includes the element’s electron configuration, electronegativity, oxidation states, and its first ionization energy...
The number of transistors increased from 2,300 in 1971 to 1.5 billion in 2015. Today, computer processors, such as the recently announced Apple A12 Bionic chip and Huawei Kirin 980, use 7 nm processes with 6.9 billion transistors on a centimeter square chip. The limits are being pushed to ...
(110) crystal plane of TiO2, respectively (Fig.2g–i). In addition, the presence of irregular lattice stripes indicates a large number of structural defects in the MXene/TiO2hybrids. Meanwhile, the introduction of TiO2nanoclusters promotes the formation of interfaces, including interfaces between ...

Thanks to the advancement of electron microscopy with aberration correction capability22, the measurement at high spatial resolution enables the atomic structure variation, element distribution, and site-specific orbital and magnetic information to be unveiled23. In this study, by using atomic resolution ...
In other words, the number,x, of Ag+cations that can be incorporated in the structure according to Na7−xAgxFe3(X2O7)4is governed by the amount of Ag+in the AgNO3solution into which the powder is immersed. This compositional monitoring is of course reminiscent of strong cationic ...
