The present invention relates to novel fused ring analogs of nitrogen containing heterocycles, and specifically, to compounds of formula (I), wherein R?1, R2, R3, R4, R5, R6, R7, R8, x, y, and z and m are defined as below. These novel compounds are useful in the treatment of ...
Alkali silicates are represented by the chemical formula SiO2× M2O, where M is typically sodium (Na) or potassium (K). Available in liquid or solid forms, silicates can form stable dispersions in WBFs at high pH (approximately pH 10 or greater). These small silicate species are able to en...
FUSED RING ANALOGS OF NITROGEN CONTAINING NONAROMATIC HETEROCYCLES The present invention relates to novel fused ring analogs of nitrogen containing heterocycles, and specifically, to compounds of formula (I), wherein R1, R2, R3, R4, R5, R6, R7, R8, x, y, and z and m are defined as belo...
a solvent. The mixture containing aromatics is introduced to a distillation zone maintained at the boiling point of the mixture of aromatics with steam being introduced at the bottom of the distillation zone. Thus, a distillation zone is necessarily employed to remove the aromatic-type compounds. ...
The formation of nonacene 1 by loss of two carbonyl groups is also evident during the high-resolution DCI MS measurement of 7a/7b in which only a peak at m/z 478.1731 from 7a or 478.1727 from 7b corresponding to the formula C38H22 (calcd m/z: 478.1722) was recorded. The de...
The LZ formula has been exploited to predict whether an ET reaction is adiabatic or nonadiabatic; however, experimental manifestation of the theory becomes a challenge. Moreover, identification of the intermediate between the two limits and elucidation of system transformation from one to the other ...

Figure 3. Chemical formula of selected xenobiotic pollutants. Microbial degradation of chlorinated solvents can involve aerobic or anaerobic pathways, depending on the number of chlorine atoms on the molecule8,22: Higher chlorinated compounds are subjected to sequential reductive dechlorination catalyzed by...
Dental nanocomposite resins have been proposed as potential restorative materials that are inevitably challenged with dynamic oral conditions. This investigation focused on the contribution of miscellaneous silane blends, used as coupling agents, to the
The general formula of zeolite is Mx/n[(AlO2)x(SiO2)y].mH2Mx/n[(AlO2)x(SiO2)y].mH2 where M is the metal or hydrogen ion of valency “n” occupying the exchangeable site in the zeolite framework [70]. Figure 3 shows the schematic of the tetrahedral arrangement of SiO4 and AlO4 ...
