believe that exchange soil acidity may be due to the presence in an adsorbed condition of both hydrogen and aluminum ions in different proportions. Hydrolytic soil acidity is caused by the presence in the soil of hydrogen ions not displaced by neutral salts from the adsorbing complex but capable...
The Stability of Lubricant Oil Acidity of Biogas Fuelled Engine due to Biogas Desulfurization The degree of acidification is considered a crucial property of lubricating oils for some applications, e.g. gas engines, as corrosive wear of machine components may be caused by acidic contaminations. For...
It was concluded that variation of H + concentration of water on conifer needles due to evaporation during the presence of cloud is likely to be less important than that due to the other reasons. In particular the increase in H + concentration from the reduction in droplet volume, due to ...
consider skunks consisting of the lower molecular weight of thiol and it is easily detectable by humans. it is also responsible for some sort of wine faults that have resulted due to some unintended reactions caused between sulphur and yeast. not all kinds of thiols hold bad odour; there are...

Solid Lewis acidity of boehmite γ-AlO(OH) and its catalytic activity for transformation of sugars in water Aqueous-phase transformation of C3- and C6-sugars toward valuable intermediates such as lactic acid and 5-hydroxymethylfurfural (HMF) using boehmite, an abundant, inexpensive and simple ...
°c for three days. the two-point bending test results revealed that water's performance significantly affected the fatiguestrengthof hma and led to its fracture before the end of the predicted fatigue life. in addition, the damage caused by water was intensified with increasing the temperature ...

quickly than they had predicted. The scientists, who gathered at Oxford University, warned that entire ecosystems, such as coral reefs, could be lost in the generation. Already the number of fish is dropping, leading to a risk of rising food prices and even starvation in so...
Nitrate underestimation caused by evaporation loss due to temperature variation during sampling may result in significant underestimation of particle acidity. In this work, a continuous system, PILS (particle-into-liquid system) coupled to two ion chromatographs (IC), was used to obtain PM2.5 ionic...
