Accurate Density Measurement: The SKZ300A Solid Gold Purity tester Precious Metal density meter Gold densitometer offers an accuracy of 0.001g/cm3, ensuring precise measurements for various objects, including solid, granular, film, and floating bodies in liquids. Wide Measurement Range: This device ...
A density-functional study of C, Si, and Ge metallic liquids is reported. Pair potentials are constructed from pseudopotentials which reproduce the Kohn-Sham densities. These lead to structure factors S(k) in good agreement with experiment, and with more elaborate Car-Parrinello calculations. It ...
An additional, in-plane field enhances the interlayer coupling for Hp(T) < H⊥ < Hc2(T), consistent with the presence of PDW correlations (thin hatched lines). Except for the thick solid line, other lines do not represent phase boundaries, but correspond to finite-temperature ...
Time-dependent density functional theory continues to draw a large number of users in a wide range of fields exploring myriad applications involving electronic spectra and dynamics. Although in principle exact, the predictivity of the calculations is lim

Estimation of the Packing density of solid polymers—III. Crystalline polymers The degree of the packing of polymer chains cannot always be estimated from a study of the density of the polymer since the density of the substance depends, not only on the average distance between its molecules, but...
3D structural modelling and implications for targeting gold mineralisation in western Victoria A 150脳150聽km area of western Victoria has been modelled in three dimensions to a depth of 20聽km. This was constructed through integrated analysis and se... FC Murphy,TJ Rawling,CJL Wilson,... - ...
The atomic structures of gold supported on (1 1 1) and (1 1 0) surfaces of CeO2 have been studied using density-functional theory calcu... Ying,Chen,and,... - 《Surface Science》 被引量: 71发表: 2008年 Stabilizing a Molecular Switch at Solid Surfaces: A Density-Functional Theory Stud...
Results show that, by selecting an optimum value for wavelength to crack length ratio, the accuracy of predictions of test data can reach R2 > 96% with mean square error (MSE) < 25e-4 (normalized values). Overall, we found that: (i) performance of both CNN and LSTM is highly ...
A family of di-, tri-, and tetranuclear copper(I) complexes supported by length-controlled silaamidinate ligands have been synthesized to show short Cu(I)-Cu(I) distances (2.43-2.62 ) and feature a linear or bent metal-metal arrangement, which is elucidated by a relativistic density functio...
