This combination of properties is unexpected, since a strong negative charge would normally make it more difficult for a protein to store electrons, as they are likewise negatively charged, and ...

See, everything around us is made up of atoms which have a positively charged nucleus surrounded by negatively charged electrons. Normally, the positive and negative charges cancel out because ...

Soils are composed of a mixture of sand, silt, clay and organic matter. Both the clay and organic matter particles have a net negative charge. Thus, these negatively-charged soil particles will ...

Direct, cationic, basic or positive dyes: contain positively charged groups. Examples include methylene blue, basic fuchsin, and crystal violet. These dyes directly bind to and stain the negatively ...

A team of researchers at the Max Planck Institute for Medical Research made a striking discovery—a protein with contradictory properties: a strongly negative charge, yet a very high propensity ...
