What immediatelycatches the careful reader's eyeis thatthe term elementis applied only to the first class of substances, and throughout the book only the members of this category are calledelements or principles, the other members of the table being called either simple bodies or “oxydable or...
Throughout the manuscript, the word ‘metastability’ refers to a sample condition describing a stable state of a dynamical system other than the system’s state of least energy. Depending on the context, the term applies both to phase equilibria and electronic defect states. The starting point ...
In the petroleum literature, an additional distinction is often made within the latter category between mixtures with low volume fraction of gas dispersed, called ”energized fluids”, while the label ”foam” is restricted to high gas volume fraction systems. The term ”energized fluid” is ...
The term “nanofluid” was first coined by Choi and Eastman [1] more than 26 years ago. Originally, the term described nanometre-sized copper particles dispersed in water to improve its thermal conductivity. Today, a nanofluid can be more accurately defined as an engineered colloidal suspension ...
it may be possible to overcome application problems while lowering environmental and human health hazards. Additionally, it was believed that the creative fusion of these two very different sorts of materials would produce a variety of property improvements in addition to structural diversity. The main...
An ink containing water, a water-soluble organic solvent and a colorant, wherein the ink exhibits a (γ cos θ)1/2 value of 4 to 6, and satisfies Formula (I): 0.3≦((γ′ cos
alkali precipitates an amphoteric yellow-brown hydroxide of trivalent gold, Au(OH)3, with mainly acidic properties; for this reason, the hydroxide is called auric acid and its salts, aurates. Heat converts auric hydroxide (trivalent gold) to auric oxide, Au2O3, which decomposes above 200°C:...
We evaluated the ionic behaviour of the biosurfactant extract, observing its amphoteric properties due to the charges of the amino acids found in its composition [25]. The dependent variables quantified were the CIELAB colour parameters (L*, a*, b*), as well as the colour differences ...
Each glucose group in a cellulose macromolecular chain has three hydroxyl groups, which can be esterified with acids. During the esterification reaction with nitric acid, nitrocellulose is produced. A nitrocellulose with a cellulose backbone has amphoteric nitro groups, which generate strong non-covalent...
