چکیده

Chemicals and thermal treatments Two types of commercial anatase TiO2 with a specific surface area of 300 m2 g-1 and 95 m2 g-1were used as-received from Sachtleben Chemie (Duisburg, Germany). Annealing was carried out in a horizontal furnace equipped with a quartz tube reactor. Typically, the TiO2 powder sample (1 g) was heated in a quartz boat at a temperature gradient of 10 oC min-1 till reaching 300 oC under flowing helium (99.999 %, 100 sccm). After reaching the desired temperature, the gas flow was switched to pure hydrogen (99.999 %, 100 sccm) and maintained for 4 or 24 h before cooling down to room temperature.

A trio of nanoswitches in redox-potential controlled communication.

A potential-controlled two-step bidirectional communication protocol between the nanoswitches [Cu(1)](+), 2 and 3 is set up, in which ligand followed by metal-ion oxidation drives two subsequent metal ion translocations (self-sorting) changing the switching state at each switch. The communication is reset to its starting point by a two-electron reduction.
