pH - Basic (alkaline) vs. Acidic Introduction to pH - the acidic and basic (alkaline) definition. pH can be viewed as an abbreviation for power of Hydrogen - or more completely, power of the concentration of the Hydrogen ionin a liquid. The mathematical definition of pH is a bit less...
8月20日,中山大学化学学院院长苏成勇带领的研究人员,在期刊 National Science Review 发表题为 Acidic open-cage solution containing basic cage-confined nanospaces for multipurpose catalysis 的论文。李康和吴凯为论文共同第一作者。 National Science Review (NSR) is an open access, peer-reviewed journal aimed...
Microtitration was adapted to deter mine the acidic-basic property and the change of the buffering systems in different pH of the aqueous solution in which the PM is suspended. The major alkalinity and buffer capacity of par ticles were analyzed and calculated. The average carbonate buffer ...
Human aFGF,encoded by the FGF1 gene,is a member of the fibroblast growth factor(FGF)family.Fibroblast growth factor was found in pituitary extracts in 1973 and then tested in a bioassay that caused fibroblasts to proliferate.After further fractionating the extract using acidic and basic pH,two ...

1.Basic, acidic extrusive and volcanoclastic rocks are known as the main rock types. 石炭纪末期本区的岩浆活动开始,早二叠世晚期和晚二叠世早期是两个主活动期。 2.The particulates have more acidic pollutants with strong acidity and have the corrodibility to grottoes. 细粒子中有较多的酸性污物并比...
These charge variants are generally referred to as acidic or basic compared with the main species. The chemical nature of the main species is usually well-understood, but understanding the chemical nature of acidic and basic species, and the differences between all three species, is critical for ...
