In contrast, as shown in Figure 2, with the Li/Si molar ratio of 1 3 in the reaction mixture, a mixture of meta-stable Li2Si2O5 (space group of Pbcn[36, 37]) and Li2SiO3 is obtained after 48 h.
Three different series of pyridine based polybenzimidazole (PyPBI) random copolymers consisting of meta-para pyridine linkages were synthesized from various stoichiometric mixtures of meta (2,4; 2,6 and 3,5) and para (2, 5) structure pyridine dicarboxylic acids (PDA) with 3, 3', 4, 4'- tetra-aminobiphenyl (TAB) by solution polycondensation in polyphosphoric acid (PPA).
Binary mixtures consisting of meta-kaolin out-performed ternary mixtures consisting of ground glass powder with meta-kaolin at equivalent dosage level.
In the crystals, the protein was found to be in the Pr state, whereas diffraction data together with resonance Raman spectroscopic and theoretical results indicate a ZZZssa and a ZZEssa chromophore configuration corresponding to a mixture of Pr and Meta-R state, the precursor of Pfr.
Unfortunately, analysis of the broadband excitation signals could not extract Lumi-Ff as a separate component because of the limited time window, and the Meta-Fr SADS was the mixture of Lumi-Ff and Meta-Fr populations.
Nadimide and tetrahydrophthalimide end-capped oligomers have been synthesized from a mixture of para- and meta-phenylenediamine, 4,4′- hexafluoroisopropylidene diphthalic anhydride (HFDA) and nadic or tetrahydrophthalic anhydride.
The objective of this paper is to study the crosslinking copolymerization of styrene (S) with a mixture of para- and meta-divinylbenzenes (mixed-DVBs).
The ethylation and the disproportionation of ethylbenzene on ZSM-5 zeolites yield a mixture of the three isomers ortho-, meta- and para-diethylbenzene.
Commonly called "meta solution," a mixture of potassium metabisulfite or sodium metabisulfite, diluted in water.
