We demonstrate an approach to the development of many-body interatomic potentials for monoatomic metals with improved accuracy and reliability. The functional form of the potentials is that of the embedded-atom method, but the: interesting features are as follows: (1) The database used for the ...

Dicopper(II) complexes of 20-membered N4 binucleating macrocycles L1–L3 derived by a cyclic [2 + 2] condensation of diformylthiophene or diformylfuran with the appropriate diamine have been synthesised and characterised by analytical, spectroscopic, magnetic, and X-ray diffraction methods. A pair ...
the said light fraction is reacted with a cracking gas containing at least one C2-C5 monoolefin, in contact with a dealuminised mordenite catalyst having an overall atomic ratio Si/Al greater than 20, so as to give an alkylated fraction and c. the said alkylated fraction is mixed with ...
Method and apparatus for gas chromatography/mass spectroscopy including a retention gap, a capillary gas chromatography column and a mass spectrometer, the improvement being a valve that facilitates temporarily venting the carrier gas from between the retention gap and the capillary gas chromatography colu...
Long term monitoring of the /sup 14/C:/sup 12/C ratio in three closed-basin lakes in the western United States has resulted in reliable estimates of the mean CO/sub 2/ invasion rates. When normalized to sea level pressure the results are 6 mol m/sup -/2 yr/sup -/1 for Pyramid La...
al., J. Appl. Phys.118, 159902 (2015)]), Allen and co-workers measured the mean square amplitudes of graphene lattice vibrations between 100 and 1300K and used a simplified theoretical approximation for the acoustic phonon modes to evaluate the maximum phonon wavelengths supported by the ...
