In many cases, diffusion of oxygen controls sintering, grain growth, and creep. High oxygen diffusivity is critical for efficient operation of many fuel cells. Additionally, oxygen diffusivities are an essential ingredient in any point defect model. Secondary ion mass spectrometry (SIMS) is the ...
Find the molar mass, moles of each element, and number of atoms of each element for 0.9992 g NaCl, 0.9822 g C12H22O11, 0.9510 g NH4Cl, 0.9723 g C6H5OH, and 1.0038 g C9H20. Find the molar mass of NaCl. What is the mass of two moles of NaCl? ...
detailed characterizations show a unique core/shell (metastable/stable phase) structure within the core of the metastable hcp phase RhMo alloy and the shell of the stable fcc phase RhMo alloy. Based on the theoretical simulations, the polymorphic ...
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 ...
Comparing the distribution difference of vertical 调平固液界面平坦度的方法resistivity of single crystal head and tail The method of adjusting plainness of solid-liquid interface 杂质条纹、生长层、平坦界面生长层形状、旋转性条纹、旋转 性表面条纹
(2 cm × 3 cm) electrode and dried under an infrared lamp to obtain a working electrode with a catalyst mass loading of 1 mg cm−2. The cathodic and anodic compartments were separated by an anion exchange membrane. Before the measurement, the KHCO3aqueous solution was purged by ...
The solubility of these monovalent metal salts strongly depends on the size and the polarizability of the metal, the solvent, and the halogen substituent.91,155 While the cesium salts are sparingly soluble in water (e.g., solubility of Cs2[B12Br12] at 25 °C is 6.36 mass %), the ...
Molecular mass markers in kilodaltons (kDa) are shown on the left. Experiments were performed two times independently with similar results. pORF43 and pORF34 of VZV are homologs of pUL17 and pUL25 of HSV-1, respectively, and represent two putative components (c1 and c2) of VZV CATC. ...
CuN4/CoN4@NC is attributable to the enhanced O2activation capability, and reduced reaction energy barriers over CoN4arising from the synergetic interactions of CuN4. Moreover, the inter-connecting hierarchical pores can largely facilitate the mass transfer and promote the accessibility of hetero-SA ...
During the heating process, the amount of hydrogen atoms (H) released from the specimen was determined by means of a mass spectrometer. The resulting data were compared with those of the standard sample prepared by implanting a known amount of hydrogen atoms into a hydrogen-free sample. (ii...
