Atomic absorption measurements were performed on various elements in steel, aluminium, brass and zinc alloys and in all cases the water vapour reduced the number of free atoms. The extent of the reduction depended on the type of sample being sputtered and the sputtering current. At the chosen ...
Notably, the TOF number of Au1/BP nanosheets was higher than those of Au NPs/BP, M1/BP, and M NPs/BP (M = Pt, Rh, and Pd) nanosheets (Supplementary Fig. 13). The TOF number of Au1/BP nanosheets was comparable to that of the state-of-the-art catalysts under similar ...
The changing models of atomic structure over time and the use of evidence to accept or reject particular models. Atomic structure in terms of the numbers of protons, neutrons and electrons for atoms and ions, given the atomic number, mass number and any ionic charge....
active sites from the opposite side of the “initialized” state. Such an “initialized” transient state is key to the high catalytic efficiency: the stably attached oxygen reduces the ionization of the metallic atom, therefore inducing decomposition of the H2O2molecule more efficiently. We calculate...
When all of the fluorine edge atoms are terminated, the interior fluorine atoms can be added in a rather random way, so that an unpaired spin can be observed with some probability. When two fluorine atoms are at nearest neighbor carbon sites, the total number of electrons around the fluorine...
In this invited review in honor of 100 years since the Stern-Gerlach (SG) experiments, we describe a decade of SG interferometry on the atom chip. The SG effect has been a paradigm of quantum mechanics throughout the last century, but there has been surprisingly little evidence that the ori...

and the resulting sulphuric acid precipitated as barium sulphate by the addition of a solution of 100 parts by weight of barium chloride (BaC12.2H20) in 300 parts by weight of water. After filtering off the precipitate and evaporating the filtrate in vacuo, 4,5-dimethyl-thiazole hydrochloride ...
(Fig.3b). The Pd metal foil and 1% M-Pd/TiO2showed an intense Pd-Pd feature at around 2.5 Å, which was absent in the O-Pd/TiO2samples (Fig.3b), confirming that no Pd-Pd bonds were present in the O-Pd/TiO2. And the fitting results showed the coordination number of Pd-O ...
