Cohen and Turnbull formula for the translational self-diffusion coefficient was tested in the free-volume cast, which itself was correlated against the isothermal compressibility, which can explain the phenomenon of transport properties in liquids, D∝exp-γ/Vf/V∗. The fractional Stokes-Einstein ...
The crystal structure of EAMT with an empirical formula of C11H18N2O3S and a formula weight of 258.34 g/mol was determined in the monoclinic crystal system with space group P21/c. This means that the crystal has a monoclinic lattice and a glide plane as the symmetry element. The non-orth...
In formula 1 above, R preferably represents a C1to C10aliphatic, alicyclic or aromatic hydrocarbon radical such as ethyl (Et), phenyl, isopropyl, butyl, propyl, n-butyl, i-butyl, t-butyl, hexyl, cyclohexyl, octyl, napthyl, etc. Non-limiting, illustrative examples of formula (1) and (2...
Based on the analysis of Fig.1, we can see that the resource technology for dewatered dewage sludge is a complicated and multi-scale science problem. It needs consider both of water treatment effect in the upstream and a series of target optimizing foundation in the downstream for the resourc...
What is the explanation for the fact that the following two compounds, which have the same molecular formula, are different molecules that do not interconvert? They are isomers, and it is unclear why they exist as different compounds. Addit...
The compound is presumed to have the formula where x is from 010 to 030, R is an alkylene radical having 2 to 5 carbon atoms and Y is the anion of a silver salt which is soluble in an alkanolamine. The alkanolamine is for example monoethanolamine, #-amino-n-propanol, #- hydroxy-...
If we measure the change in dissolved oxygen or hydrogen peroxide concentration using an electrochemical device, it is possible to measure the glucose concentration— if we know the relationship between the change and the glucose concentration before measurement. As we can see in the above formula,...
conductometric and magnetic measurements. The results suggest that the symmetrical Schiff-base is a bivalent anion with tetradentate N2S2donors derived from the thiophenole groups and azomethine nitrogen. The formulae was found to be [M(mabenzil)] for the 1:1 non-electrolytic complexes. Alumina-...
Figure 1 General formulae of carboxamide (a), amidine (b), amidinate complexes (c), and amidinosilanes prepared in this work (d). Since about two decades the research of our group is concerned with different types of silicon-nitrogen compounds like silicon carbodiimides (Balan et al., 20...
and about 1-6 molar proportions of a proton donor selected from glycols and compounds corresponding to the formula ROH wherein R is hydrogen, alkyl, aryl, alkaryl, or aralkyl and wherein any alkyl group contains up to five carbon atoms and any aryl group is phenyl or naphthyl, the improv...
