Wigner-Seitz radius (ws), and atomic volume (at)—in the properties of nanoparticles of elements from Sc to Au and elements (Ca, Sr, Ba, Zn, Cd, and Hg) in dependence of the electronic structure of atoms; number of , , and valence electrons; and excitation energies of atoms is ...
This enables them to be good model nanomaterials to disclose the correlation between surface atomic arrangement and properties. Moreover, by virtue of this feature, desired catalytic performances would be realized1,2,30–37. For example, it has been reported that the catalytic performance of the ...
In recent years, international competition has spurred the development of novel alloys with superior properties. Diffusion plays an important role in a great majority of metallurgical processes, such as heat treatment and welding, which is of great importance for practical and scientific purposes [1]...
In the effort to improve the electrocatalytic properties of FC cathodes, a volcano-shaped relationship was confirmed between the rate of the cathode reaction and the oxygen adsorption energy for the best catalytic activity of the Pt-Pd bimetal [218,219]. The ORR of Pd-Co-Pt/C catalysts ...
(mPhDP)4]2+,1) and by trimethylene-bridged diphosphines ([Au6(TMDP)4]2+,2) (Fig.1a, b) are significantly different. Since the electronic structure features and optical properties of molecular-sized Au clusters are essentially governed by their nuclearity and geometrical structures of the ...
Answer and Explanation:1 We need to determine the mass number of uncharged Au with 100 neutrons. In order to determine the mass number, we need to know the number of protons... Learn more about this topic: Subatomic Particles | Properties, Characteristics & Ty...

In this manuscript, the main harmonic of a high-frequency Nd:YAG laser is applied to forming gold and silver NPs individually; whereas, second harmonic irradiation with 532 nm wavelength, is used for the synthesis Au/Ag BNPs. The main goal is to characterize optical properties and to find ...
process conditions (characterized in terms of the composition and two atomic deposition characteristics) onto eight indicators of material structure (consisting of X-ray diffraction (XRD), thickness, density, and surface roughness), and onto two indicators of material properties (hardness and resistivity...
