Molar mass of ethane ( CH3CH3 ) =12x2+1x6 =30 Molar mass of ethanol ( CH3CH2OH ) =12x2+1x6+16x1 =46 As you see the their molar mass is similar with pared to the large hydrocanbon molecule. 分子或其他化合物有多大，可以从它们的摩尔质量得知，当然，前题是它们有相同的结...
Protein tyrosine nitration (PTN), in which tyrosine (Tyr) residues on proteins are converted into 3-nitrotyrosine (NT), is one of the post-translational modifications mediated by reactive nitrogen species (RNS). Many recent studies have reported that PTN

In this paper,the application of molecular catalysis for steam reforming of ethanol(SRE)is reviewed.Eight metals(Ni,Co,Cu,Pt,Rh,Pd,Ir and Ru)have shown high catalytic activity for SRE.Among them Ni and Rh are very promising because of high d character in the metal bond and low metal-oxy...

while the density of clusters is equal to the particle mass density78,79. We computed the Wigner–Seitz radius (rw), the number of ENMs in the analysed agglomerate (n), the number of surface elements (S), the surface–volume ratio (SV) and the aggregation parameter (AP)78. The Wigner...
The alcohol biomarker phosphatidylethanol (PEth) comprises a group of ethanol-derived phospholipids formed from phosphatidylcholine by phospholipase D. The PEth molecular species have a common phosphoethanol head group onto which 2 fatty acid moieties are attached. We developed an electrospray ionization...
