The temperature coefficient of the potential of zero charge of stepped faces of gold in contact with aqueous perchloric acid solutions

Potentials of zero charge, E_σ=0, and the temperature coefficients of E_σ=0 for stepped surfaces of gold single crystals (511), (533), (331) and (311) were obtained from the minimum of the differential capacity curse in dilute HClO₄ solutions. The results are compared with those obtaine for the low index faces and discussed in terms of the effect of the surface density of steps and the step orientation. The possible relevance of the effect of steps on the interaction of water with gold surfaces is discussed.

Differential Scanning Calorimetry and Hydrodynamic Study of Bacterial Viruses. About possible heat effects in hermetically closed calorimetric vessels with free volume above the liquid

The phase transitions occurring in aqueous solutions of macromolecules and their complex structures (like order-disorder transitions in proteins or nucleic acids solutions) are usually accompanied by small changes in their specific partial volumes. If the quantity of these substances in the closed calorimetric vessels is relatively large (few mg) and if the phase transition is accompanied by a high change of specific partial volume (like in solution of bacteriophages),it is possible to detect some imaginary heat effects in the DSC calorimeters which have closed (sealed) vessels with free volume above the liquid.
