. The solubility of these monovalent metal salts strongly depends on the size and thepolarizabilityof the metal, the solvent, and the halogen substituent.91,155While thecesiumsalts are sparingly soluble in water (e.g., solubility of Cs2[B12Br12] at 25°C is 6.36 mass %), thesilversalts ...
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 ...
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-
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 ...
The main limiting factor of the imaging rate of AFM is the response speed of the moving components of the atomic force microscope, i.e., the probe and the scanner. The response speed of these components is a function of the inverse of the square root of their mass (v∼1/m). ...
The Rutherford Atom 1911 Simulation Evidence: Gold Foil Experiment % of alphas are not deflected % of alphas are radically deflected Theory 1.Most of the atom is empty space. 2.There is a small dense nucleus in the center of the atom that makes up most of the mass. Electrons circle the...
The formation and photodissociation of group Ⅳ(Si,Ge,Sn,Pb)/P binary cluster ions,produced by laser ablation,were studied with a tandem TOF mass spectrometer.The stability of these cluster ions is influenced by their electronic and geometric structures,and the geometric stability becomes more impor...
the mass activities of RhMo Nanosheets/C is 6.96 A mgRh−1; this is 21.09 times higher than that of commercial Pt/C (0.33 A mgPt−1). Density functional theory calculations suggest that the interface aids in the dissociation of H2and the H species can then spillover to weak...
Since the depth of characteristic X-rays produced by electrons is about one or two micrometers for the elements with medium atomic mass28, the whole MnS with diameter of several hundred nanometers is in the detection range of EPMA. Therefore, the co-existence of Mn and Cu signals in Fig....
