Evidence of the electrical conductivity of DNA and of its important mechanisms has been discussed for a long time and has led to a theory of electron conduction in biopolymers [25, 82]. From this it appeared that the major carrier of conductivity is either electronic or ionic, depending on the temperature of the sample, the water content, and the fact that the conductivity of native samples is higher than that of denatured samples. Following electrochemical oxidation of dsDNA and ssDNA in electrolyte solutions over a wide range of pH, interesting electrochemical properties of a glassy carbon electrode with dsDNA or ssDNA adsorbed on the electrode surface were observed [68]. [Pg.101]

A further distinguishing feature of MOFs over other classes of porous materials is the extreme diversity of their surface chemistry, which can range from aromatic to highly ionic depending on the chemical nature of the building units used. This notably includes the achievement of multiple pore environments within individual materials. An important consequence of this versatility is that the surface chemistry can be tuned for highly specific molecular recognition and catalytic processes (see Sections 1.2.2, 1.2.3 and 1.2.4). [Pg.8]

Conduction of electric current in conductors can be electronic or ionic, depending on the type of charges involved. Electronic conduction is found in all metals and also in certain other nonmetals. Ionic conductors are also known as electrolytes. Substances that ordinarily are not conducting can produce ionic conduction after being dissolved in water or another solvent (e.g., electrolyte solution and weak electrolyte ). The relative amount of substance present in a solution or a mixture is known as its concentration. The different concentration units used mostly are molarity, molality, normality, and mole fraction. The acidity or basicity of a solution is measured by a relative measurement called the pH of solution. It is defined as the cologarithm of the activity of dissolved hydrogen ions (H" "). Pure water is said to be neutral. The pH for pure water at 25 °C (77 °F) is close to 7.0. Solutions with a pH less than 7 are said to be acidic and solutions with a pH greater than 7 are said to be basic or alkaline. [Pg.29]

In composition they are fine dispersions or suspensions of synthetic polymer particles (0.1 p to 5-6 p) in an aqueous stabilisation medium. The process of polymerisation can be of either of two types addition polymerisation or condensation polymerisation. The main components of the aqueous stabilisation medium, apart from water, are colloids such as polyvinyl alcohol, cellulosic or starch materials and/or surfactants, being anionic, cationic or even non-ionic depending on the polymer type. [Pg.219]
