The possibility of passivizing the nanoparticle surface with organic molecules is a way to control the nanoparticle shape. Using separation techniques such as electrophoresis, it is possible to obtain a batch of particles with the same mass in average and hence the same number of atoms. Passiv...

Clusters in systems as diverse as metal atoms, virus proteins, noble gases, and nucleons have properties that depend sensitively on the number of constituent particles. Certain numbers are termed ‘magic’ because they grant the system with closed shells
Due to the difference in Z-contrast, the supported Pt species can be easily distinguished from Sn atoms, as shown in Fig. 1. As a control, the obtained Pt NPs of Pt/ND@G (nanoparticle diameter, d = 2.81 ± 0.95 nm) were located on the ND@G surface (Supplementary Fig...
We provide a base stock comprising hydrocarbons with consecutive numbers of carbon atoms, wherein the base stock has a boiling range from 388 to 538°C, a VI from 105 to less than 120, and a Noack volatility from 6.6 to 11.5 wt % or a CCS VIS at -25°C from 2500 to 4500 mPa.s...
In many cases, laser-nanoparticle interactions result in the formation of plasmonic nanobubbles, and the dynamics of nanoparticles and nanobubbles are inseparable. So far, very little attention has been paid to the number density. Here we report the first observation of number-density-dependent ...
The invention relates to a reactor for consuming a nuclear fuel that contains atoms of elements having a low atomic number (Z) and a low mass number (A), wherein the nuclear reactor (1) comprises a vessel (2) containing a reaction chamber (3). This reaction chamber (3) is topped and...
We build nanoparticles in an atomically defined manner through the use of a high-fidelity molecular container we call an atomic metron, which is used to select and count the metallic ions that will make up the resultant nanoparticle. After a defined number of ions are selected, the metron may...
Two different magic number behaviors in supported metal clusters, which contain several to hundreds of atoms, are revealed on a series of fcc(001) metal surfaces based on the calculations with the tight-binding potential. The magic number sequence persists on some surfaces while gradually disappears...
