of an polyalkyl ether/polyaryl ether sulfone copolymer which is composed of repeating units of (i) the formula -Ar1-X-Ar2-O-, (ii) the formula -Ar3-Y-Ar4- and (iii) the formula (-RO-)k, [X is SO2; Ar1 to Ar4 are each a (nucleus-substituted) 6-30C bifunctional aromatic ...
RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992) Interactions NAAL SILICATES BOUND...
High molecular weight temperature-resistant polymers of polytriazine structure obtained by heating cyanamides of the formula I r -- (nh-cn)n in which R represents an aliphatic, cycloaliphatic, heterocyclic or aromatic radical, optionally interrupted by oxygen and n is a number from 2 to 5, with...
A polymer compound comprising a repeating unit of below formula (1) or (2), and having a polystyrene reduced number average molecular weight of 10<3> to 10<8>, <CHEM> (wherein, Ar<1> and Ar<2> each independently represent a trivalent aromatic hydrocarbon group or a trivalent heterocyclic...
The generation of O2 (1Dg) by energy transfer from HRP- catalyzed production of excited triplet acetone from IBAL oxidation was monitored using water-soluble EAS, which can react with O2 (1Dg), yielding EASO2 as the specific oxidation product (Fig. 4). To this end, EAS was incubated at...
The structure of kinesin is shown in Fig. 1A. Its spherical head is used to generate power, like an electric motor; And its tail is combined with cargo and then transport [25]. The total molecular weight of kinesin is 380 × 106. There are approximately 45 species in kinesin ...

The IR bands at 1049 and 1014 cm−1 were attributed to vibrations of sulphate salts and that at 1385 cm−1 to the νasSO2 mode of organic covalent sulphates. In the 1300–1180 cm−1 range various contributions of alkyl and aryl sulphate salts, sulphonamides, sulphoamines and organic...
(d) An isosurface representation of the HOMO of SO2, shown in red and blue to encode the phase, is overlaid on top of a ball and stick model. We see the highest electron density in the b-axis direction, which should result in higher rates of ionization and recombination in this ...
