Technical note: Statistical analysis of pellet size variation in commercial catalysts
The size of commercial catalyst pellets is distributed over a range of values. The suitability of the normal, log-normal and Weibull distributions to model pellet size variation was judged by three quality-of-fit criteria: the coefficient of determination, Akaike information criterion and Kolmogorov-Smirnov test, respectively. It is concluded that the normal distribution is most appropriate to r...

Micellar electrokinetic chromatography analysis of tetrahydrogestrinone and related anabolic androgenic steroids.
Tetrahydrogestrinone and related anabolic androgenic steroids (AASs) have been used extensively for performance enhancement (doping) in sports due to their ability to accelerate protein synthesis and improve phys. performance (F. C. W. Wu, Clin. Chem., 1997, 43, 1289-1292). The sepn. of these AASs was performed by micellar electrokinetic chromatog. (MEKC) using borate/borax buffer (200/50 mM...

A novel failure analysis of multi-walled carbon nanotubes in epoxy matrix
The failure analysis of reinforcing elements is of great significance to understand the structure-property relationship in polymer composites. Herein, we reported an improved methodology to ascertain and contrast the failure modes from one pair of homologous fracture surfaces of multi-walled carbon
nanotubes (MWCNTs)/epoxy samples at high-magnification using scanning electron microscopy....

Crystalline Structure of Injection Molded β-Isotactic Polypropylene: Analysis of the Oriented Shear Zone
Although both shear flow and β-nucleating agent (β-NA) could separately induce β-crystal in isotactic
polypropylene (iPP), their combination, particularly in the typical industrial processes, in fact has received comparatively little
attention. In the current study, two-dimensional wide-angle X-ray diffraction and small-angle X-ray scattering (2D-WAXD/
SAXS) measurements were performed to inves...

Complexation of different metals with a novel N-donor bridging receptor and Hirshfeld surfaces analysis
A novel N-donor bridging receptor R: 4,40-methanediylbis(2-ethyl-5-methyl-1H-imidazole) has been synthesized from 2-ethyl-4-methyl-1H-imidazole and formaldehyde in the presence of potassium hydroxide. This receptor then formed complexes with different transition metals ([Co(NO3)2, CoCl2, Ni(NO3)2 and CuCl2]) in different solvent systems and obtained ?ve different complexes. Wherein, the complex fo...

Comparison and Thermodynamic Analysis of Crystallinity of noncrosslinking and Crosslinking Fluorinated Acrylate Copolymers Films
In this manuscript two different fluorinated acrylate copolymers films, one was non-crosslinking Stearyl acrylate/2-(perfluorooctyl) ethyl methacrylate (SA/FOEMA) and another was cross-linked SA/2-hydroxyethyl methacrylate(HEMA)/FOEMA/hexamethylene diisocyanate trimers (N3300), were prepared and their crystallinities were investigated by means of X-ray diffraction (XRD) and differential scanning c...

An analysis of Lyocell fiber formation as a melt-spinning process
In order to gain an understanding of the process of Lyocell fiber formation, the melting and solidification behaviors, heat capacity and density of cellulose N-methylmorpholine-N-oxide monohydrate (NMMO-MH) solutions were studied by differential scanning calorimetry (DSC) and dilatometry, and the diameter development of Lyocell fibers in the air gap was measured online. It was found that the ...
