Influence of structure parameters

To evaluate the influence of structural parameters governed by the cyclophosphazene core concerning the valency and the spatial orientation of epitopes, as well as the nature of linkers directly related to the ligation technique used for the mannoside incorporation, the authors performed preliminary kinetic turbidimetric assays with Con A. Insoluble cross-linked complexes formed rapidly for all compounds, without marked difference for the hexavalent analogues. On the other hand, the incorporation of additional mannosyl units led merely to statistical binding-affinity enhancements, notably for the less-dense decamer 194, which presents favorable extended intersugar distances. 

The assessment of relationships between fracture resistance and structural parameters would require analyzing experimental results obtained at constant (Tg — T). Unfortunately, most of the results reported in the literature for materials of different Tg were obtained at room temperature. Conclusions regarding the influence of structural parameters on the fracture... 

This chapter is concerned with the improvement of catalyst performance through a better pellet design. This design relates to the physical properties of the catalyst pellets for given kinetics and does not involve the chemical composition of the catalyst. Examples are given to illustrate the influence of structural parameters on catalyst performance.

Roussel and Popescu [54] extended this work by developing a lipophilicity parameter, log k w The authors were able to explain the relationship between chiral retention of the enantiomers and their lipophilic interactions with the CSPs. Quantification of the influence of structural parameters Xi, X2 and X3 was also possible. The relationship between lipophilicity and chiral chromatographic behavior was explained for compounds 23-30 and an extension to other alkyl substituted atropisomers was made. A related study concerning the resolution of 23-30 on various p-methylbenzoyl cellulose beads has also been published [55] but will not be described here because it employs the same methodology as above. 

Subsequently, two pathways may be entered, one leading to perthiyl (plus thio-late), while the other results in thiyl radicals (plus perthiolate). An example shedding light on the strong influence of structural parameters on the relative yields of these two options has been described by Everett et alJ who report reaction 31a to dominate for penicillamine derivative (> 95%), as opposed to an only =20% yield of this process in the reduction of cysteine trisulfide. A similarly striking difference between these two trisulfides was found with respect to the OH-induced formation of perthiyl radicals (63% for R=Pen and 10% for R=Cys).

In practice, tack experiments, translation tribometry, and atomic force microscopy (AFM) are used to quantify adhesion and friction at the macro- and nanoscales. In order to record dissipation phenomena, the influence of structural parameters (degree of crosshnking and presence of free chains) and experimental factors (friction speed, normal force) is analyzed. 

For the purpose of studying of influence of structural parameters of NR samples processed in various temperature time intervals on properties of rubber compounds and rubbers on their basis, within the standard filled compounding for NR [5] rubber mixes were made and their vulcanizing properties and physicomechanical properties of vul-canizers were defined. Results of the conducted researches are given in Table 10.2.
