Pt3Cu, also known as orthocuproplatinum, is a metallic-lustred, non-transparent alloy that belongs to Nickel Strunz class AG (alloys of the platinum-group elements) [14]. Three different synthesis methods are used to create Pt3Cu nanoparticles on multiwall carbon nanotubes (MWCNT): a thermal...
1. The electronic structure and bonding in these crystals appear to be quite similar, but there are subtle differences in bonding in these crystals due to differences in their compositions in different metallic elements and crystal geometry. 2. The presence of very narrow metallic state of Cu in...

A long-standing crucial question with atomic nuclei is whether or not α clustering occurs there. An α particle (helium-4 nucleus) comprises two protons and two neutrons, and may be the building block of some nuclei. This is a very beautiful and fascina
2f). Although the overall fold of the MTase domains of dengue NS512 and SARS-CoV-2 nsp169 is similar, the loops connecting the secondary structural elements of NS5 MTase are longer and have a slightly different orientation than nsp16. The sequence identity between the two MTases is low (...
