Precise control of thermophysical properties of liquids through tailor-made design of the liquid molecular structure is a goal that, if achieved, could have significant positive impacts on machine design, performance and durability. In this work we show how the breakdown of the Green–Kubo relations...
Selective hydrogenation of the carbonyl bond in α,β-unsaturated carbonyl compounds is rather challenging owing to the more feasible hydrogenation of ethylenic bond from both thermodynamic and kinetic aspects. Here, we demonstrate a facile emulsion-based molecule-nanoparticle self-assembly strategy for t...
Reagent used in the preparation method for the atomic scale precious metal nanoparticle stable colloidal suspension is common, synthesizing steps are simple, cost is low, pollution cannot occur, mass production is easy to conduct, and addition of surfactant and additional reducing agent is can not ...
Isotopes up to 254Fm and beyond can be produced by intense neutron irradiation of lower elements, such as plutonium, using a process of successive neutron capture interspersed with β-decays until these mass numbers and atomic numbers are reached. Heavier elements are produced by fusion reactions....
active sites and the mass transport properties34,35,36. The ORR catalytic efficiency and kinetics are correlated with multiple steps, including the adsorption and activation of substrates, charge transfer, and desorption of products4,37. Remarkable ORR enhancement is difficult to achieve by optimizing...

However, molecular mass determination by gel filtration may be not accurate due to the poor resolution of the NATURE COMMUNICATIONS | 8:16064 | DOI: 10.1038/ncomms16064 | www.nature.com/naturecommunications 9 ARTICLE NATURE COMMUNICATIONS | DOI: 10.1038/ncomms16064 gel filtration retention times ...
Bertholletover that very proposition. Dalton’s measurements, crude as they were, allowed him to formulate theLaw of Multiple Proportions: When two elements form more than onecompound, the masses of one element that combine with a fixed mass of the other are in a ratio of small whole ...
In combination with the enhanced mass transport originating from these cavitation phenomena, this allows homogeneous dispersion of the NPs throughout the support channels-provided appropriate sonication times (~h) are applied [69]. In the case of in situ synthesis, the small size of precursor ...
