A REVISION OF THE ATOMIC WEIGHT OF CADMIUM. V. The Electrolytic Determination of Cadmium in Cadmium Sulfate. Gravimetric synthetic mixtures of seven enriched, purified cadmium isotope materials were used to determine the correction factors for mass fractionation (... GP Baxter,CH Wilson - 《Journal...
But the atomic mass number of oxygen is 16. QED The chemists used a "atomic mass unit" (amu) scale such that the natural mixture of oxygen isotopes had an atomic mass 16, while the physicists assigned the same number 16 to only the atomic mass of the most common oxygen isotope (16O...

Effective atomic numbers have been calculated for a range of ferrous-sulphate and polymeric gel dosimeters using mass attenuation coefficient data over the energy range 10 keV to 10 MeV. Data is presented relative to water to allow direct comparison over a range of energies. These data provide ...
During the sampling phase, time steps of 4.0 fs were used, enabled by constraining all bonds involving hydrogen atoms64 to their equilibrium lengths as well as applying the hydrogen mass repartitioning method65. Data analysis was performed using VMD 1.9.366 and CPPTRAJ67. Simulation set-up ...
A method for simultaneous determination of Cu, Cd, Fe, As, Ag and Al in zinc-lead bulk concentrate was developed using inductively coupled plasma- atomic e... 范丽新 - 《中国无机分析化学》 被引量: 9发表: 2013年 Simultaneous determination of zinc, cadmium and lead in manganese sulphate ele...
(in terms of mass) to use a CELSS instead of transporting consumables. With a primitive CELSS this happens at about 145 days, increasing the efficiency will bring the break-even duration point lower. The mass of the CELSS is constant regardless of mission duration, the mass of consumables ...
Here the reversible deposition and dissolving of atomic Sn on the Cu electrode was directly confirmed by the EQCM characterization. As shown, the mass on the electrode presented a clear and sharp increase as a result of the Sn deposition and then gradually decreased to the original value because...
Technical advances in proteomics mass spectrometry: identification of post-translational modifications. The importance of post-translational modifications (PTMs) of proteins has become evident in the proteomic era as it plays a critical role in modulating cel...

volumes discarded through port 4 and the ¯ow of the sample carried to the detector were evaluated by determining the mass collected in the time intervals established. The optimisation of each step to eliminate chemical interferences was performed using aluminiumas inter- ferent. In fact, prelimina...
