n-butaneenergy-current autocorrelation functionsatomic contributionsmolecular centremass positionsDifferent momentum and energy-current autocorrelation functions are obtained in polyatomic fluids depending upon whether the individual atomic contributions of mass, linear momentum and energy are supposed to be ...
To further reduce the mass of the vest the protective material varies in thickness to account for pelvic bone marrow depth and the natural attunation properties of human tissue. StemRad 360 Gamma antiradiation vest left: rear view, right: front view it hangs down farther in the rear compared...
(2) the highest and negative prices of the elements of the same family are the same (3) all single qualities are shown to be zero 3 elemental melting point (1) the same period element increases with the number of atomic number, the melting point of the metal single mass of the element...
Platinum-nanoparticle-based catalysts are widely used in many important chemical processes and automobile industries. Downsizing catalyst nanoparticles to single atoms is highly desirable to maximize their use efficiency, however, very challenging. Here
achieve a current density of 10 mA cm−2. Moreover, the mass activity of Pt-ACs/CoNC is 28.6 A mg−1at the overpotential of 50 mV, which is superior to the commercial Pt/C with 20 wt% of Pt under identical testing conditions. This simple method has been extended ...
There were some reports that claimed iced or frozen turbines were a significant cause of lost wind power generation, but the real culprit was a relatively common, and predicted winter storm weather pattern that included long periods where high pressure covered a huge land mass. When atmospher...
Reactions of atomic transition-metal ions with long-chain alkanes Understanding metal ion interactions with long-chain alkanes not only is of fundamental importance in the areas of organometallic chemistry, surface chemis... C Rui,L Liang - 《Journal of the American Society for Mass Spectrometry》...
Pt/C. In addition, the Pt–Ru dimers exhibit better HER activity than Pt single atoms. We further calculated the mass HER activities based on the mass loading at the overpotential of 0.05 V (The metal mass loadings for Pt/C, Pt single atoms, and Pt–Ru dimers on the electrode are...
where c is the measure of the composition such as mole fraction, concentration in moles, or mass per unit volume. Here, a and b are the two components of the mixture to be separated, and 1 and 2 are the two product streams after the separation. The extract is enriched with one of th...
Total mass attenuation coefficients, 碌m, effective atomic number, Zeff, and effective electron density, Neff, of different gases - carbon dioxide, methane, acetylene, propane, butane, and pentane used in radiation detectors, have been calculated for the photon energy of 1 keV to 100 GeV. Each...
