WC grains in WC-Co alloys are shaped as truncated triangular prisms, each with a basal plane of a (0001) truncated triangle and two {1100} prismatic planes, one narrower and one wider. This anisotropic shape is related to the polarity of the WC lattice, which comes from the difference in...
If this is so, does this lead to the exclusion of putative interactions involving the C‒H low polarity bonds of the ‒CH3moiety? If interactions involving the latter are not insignificant, do they contribute to controlling the tilting of PbI64−octahedra in o-CH3NH3PbI3and can they be...
With regard to drug design, introducing IMHBs has been put forward as a strategy to mask regions of higher polarity that might otherwise reduce cell permeability28. However, prior to the advent of the EPSA technique, identification of IMHBs, by either computation or experimentation, was ...
In practice, however, the photophysics of many fluorescent probes are more or less sensitive to the polarity, pH, and presence of quenching molecules. These properties may, of course, differ considerably between different regions of a protein. Consequently, the choice of fluorescent label is ...
The calculated molecular descriptors indicated that all compounds in the series (1–11 and indinavir) were uncharged at physiological pH and had rather high molecular weights (>613.9 g/mol), lipophilicities (>3.19), rotatable bonds (>12), and TPSAs (>120.0 Å2), as shown in Table 1. ...
In alternative embodiments, the dehydroiodination reaction may be conducted by contacting an aqueous solution of said basic substance with a solution of the trihydroiodoperfluoroalkane in one or more organic solvents of lower polarity such as an alkane (e.g., hexane, heptane, or octane), ...
23. The method of claim 22 wherein nitrogen nuclear quadrupole resonance polarity is achieved prior to decreasing the field intensity. 24. The method of claim 18 including the step of obtaining both of said NMR responses in timed sequence after the baggage is polarized in a magnetic field. ...
The energy source may comprise a voltage source that is electrically connected to the metal layer and the electrode with a polarity such that the metal layer forms an anode and the electrode forms a cathode. The anodization system may be configured to perform electrochemical and/or photoelectrochemi...
Although specific conductivity types or polarity of potentials have been described in the examples, it will be appreciated that conductivity types and polarities of potentials may be reversed. Each signal described herein may be designed as positive or negative logic. In the case of a negative logi...
