    Abstract Dating needs an age-dependent phenomenon (a "clock"), a procedure for monitoring the advance of time by measuring a physicochemical quantity, and, in the case of archeological artifacts, a sampling procedure that guarantees the representativity and integrity of the dated objects. Metal corrosion in an aerobic atmosphere is a phenomenon whose advance can in principle be used as a clock that depends on the environmental conditions. In spite of the limitation imposed by differences in local conditions of corrosion, a new approach for age determinations has been developed and applied as a feasible tool for age determinations of metallic specimens studied by archeologists and historians. These techniques allow the recording of specific electrochemical features characterizing the state of growth of corrosion patinas, i.e., they are based on corrosion clocks. The application of corrosion clocks for age determination is possible in favorable cases where the corrosion happened to proceed uniformly and continuously. The proposed methods for dating of lead, copper/bronze, leaded bronze, and gold are mainly based on the voltammetry of immobilized particles (VIMP). This technique is exceptionally useful in the archeological domain because it requires only submicrogram sample amounts and permits sampling of different locations on the object, thus yielding representative data collected essentially noninvasively. Reported methods for dating of metals include lead, copper/bronze, and gold, obviously in all cases assuming uniform conditions of corrosion in a moderately aggressive environment. In the case of lead, age markers are porous PbO and PbO

    Abstract For the first time, an all-pseudocapacitve supercapacitor based on Co and Fe nanospinel oxide coatings was developed for application in alkaline solution. The Co3O4 nanoflakes and the Fe3O4 nanospheres are coated on Ni foam by a simple autocombustion method without a binder. They exhibit pseudocapacitive behavior with high areal capacitances of 691 m F cm−2 and 404 m F cm−2, respectively, that originates from multiple electron transfer reactions. Furthermore, systematic studies of the two electrodes during 4000 charge-discharge cycles by cyclic voltammetry, field emission scanning electron microscopy, and electrochemical impedance spectroscopy reveal high performance stability that are due to the multiple reversible redox reactions. Finally, the practical application of the electrodes was investigated in an asymmetric supercapacitor. The supercapacitor showed a capacitance of 191.6 m F cm−2, and average energy and power densities of 52.5 μWh cm−2 and 1.2 mW cm−2. This performance for a supercapacitor that is developed by a low-cost and sustainable process is highly appealing for practical applications.

    Abstract Insertion electrochemical electrodes exhibit simultaneous electron and ion transfer, with the two transfers proceeding across different interfaces. Herein the thermodynamics of the overall electrochemical electrode reaction is discussed with respect to the thermodynamics of these two charge-transfer equilibria. This Minireview includes insertion electrochemical systems where the redox centers are in a solid phase and the ions are transferred between that phase and a solution, and also systems where the redox centers are in a liquid phase that is immiscible with another liquid phase and ions are transferred between the two liquid phases. The Minireview is intended to spark similar studies on battery materials to improve their performance.
