James G.SpeightPhD, DSc, PhD, inHandbook of Industrial Hydrocarbon Processes (Second Edition), 2020 3Molecular weight Themolecular massof a substance is the mass of one molecule of that substance, in unifiedatomic mass units(Drews, 1998; Speight, 2015). This is distinct from therelative molecu...
Bioaccumulation of Cobalt (Co) and Chromium (Cr) in periprosthetic tissues. (a) Co ion concentrations in periprosthetic tissues surrounding control (CTR) and metal-on-metal (MoM) implants, as detected by inductively coupled plasma mass spectrometry (ICP-MS). Significant differences in Co concentrati...
The products have been characterized by their proton NMR and mass spectra, and by single crystal X-ray diffraction investigations. (η 5-C 5H 5) 3Y · OC 4H 8[η 5-C 5H 5) 3 La · OC 4H 8] crystallizes in the monoclinic space group P2 1/ n[ P2 1/ n] with unit cell ...

是指一个 formula unit 的 particle 的 relative mass。本来是该用于没有 molecule 的 particle 的 relative mass。例如 NaCl 含 ions 而不含 molecules,所以没有 r.m.m.,但 NaCl 含一个 Na+ ion 和一个 Cl- ion,所以 f.m. of NaCl = 23 + 35.5 = 58.5。但 f.m. 可应用于任何...
Such a direct nonadiabatic (DNA) approach, see Section 2.3, accounts strictly for the (nonadiabatic) effects of the finite mass of the nuclei and has been intensively developed in recent years. Such calculations are relatively costly considering a large number of rovibrational states of the ...
The molecule mass here has been set equal to 1, while \(\zeta\) is the viscous drag and the Gaussian white noise satisfies the following properties: \(\langle \xi _{BM}(t)\rangle =0\) and \(\langle \xi _{BM}(t_1)\xi _{BM}(t_2)\rangle =2k_BT\zeta \delta (t_1-t_2)...

Cytokines are not only responsible for autocrine and paracrine signaling within the myocardium but also for endocrine signaling throughout the body, especially affecting striated muscle mass through the induction of muscle wasting and cachexia. Transforming growth factor signaling and alterations to...
