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

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
than that of Pt SAs. Szanyi et al.19found that Ru clusters favored CH4formation in contrast to Ru single atoms. Due to the limited ability to activate hydrogen, single Ru atoms can only allow CO formation but cannot further hydrogenate it to CH4. However, we find later that the modulation...
We describe a series of isostructural porphyrin-based coordination polymers, each containing Au single atoms (COFX-Au, X = 1 through 5), which are applied to photocatalytic nitrogen fixation. Au single atoms, as well as light-harvesting antennae, are immobilized by the porphyrin building blocks...
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 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...
3.The nuclear reactor (1) according to claim 2, wherein the nuclear fuel comprises atoms of elements with a low atomic number (Z) and a low mass number (A). 4.The nuclear reactor (1) according to claim 1, wherein the nuclear fuel comprises one or more of the following elements: Li...
Hinterwirth and co-workers [23] employed a similar mathematical equation to calculate number concentration of the gold nanoparticles in their formulation. Taking their study as an instance, if initially 55 mL of 1.14 mM Au(III) atoms was used in the construction of particles and the number of...
The method used permitted to verify a striking correlation between the intensity of the vdW forces and the number of contacts.This result shows that the current way we think at interfaces is not valid. In addition to the huge impact at the level of fundamental science, the results of the ...
