Sentence examples for additional acid from inspiring English sources

Third, acid rain is in part a cumulative problem; as the acid-neutralizing capacity of soils gets depleted the ecosystems become increasingly sensitive to additional acid inputs.

Based on their permanent charge, these chiral ionic liquids could be applied as organocatalysts in asymmetric aldol reaction of 4-nitrobenzaldehyde and acetone, and good yields and selectivities up to 80%ee could be obtained without additional acid.

The raw rice husks (RH) can be directly phase transited into the amorphous SiO2 (RHstructureucture with highly nanoporous fragments by the thermal annealing with additional acid hydrolysis process.

The subsequent dehydration to THF can be promoted by applying higher temperatures; however, selectivities to tetrahydrofuran remain low over typical Cu/ZnO catalysts unless additional acid sites are implemented.

At higher surface loadings corresponding to dry impregnation or pore volume filling that are more representative of industrial catalyst preparation recipes, however, the pH buffering effect of the oxide becomes so pronounced that additional acid is required to sufficiently charge the oxide surface and facilitate full platinum uptake.

Chugh et al. (2007a) presented additional acid-base accounting data for CCPW and FCPW samples collected from another similar preparation plant and found that: (1) the FCPW represented 10%15%% of the coal waste, and (2) the sulfur content is typically lower for FCPW as compared to CCPW.
