Electrochromic smart window for modulation of infrared heat by Loke, Jie Yi

“…The improved electrochromic performance is due the existence of Nd-Mo co-dopants that restrict the trapping of Li+ ions within the α-WO3 framework. This reduces the degree of crystallization of α-WO3 layer and improves the electronic conductivity by transferring excess electrons to the conduction band of the SnO2. …”

Engineering memristor : control over the fourth fundamental element for memory application and beyond by Ge, Ning

“…This is especially shown in the recent neuromorphic computing since both neuron and memristor operate in ions. In many ways, a memristor is very similar to a synapse (a biological connection between two neurons), which is able to modulate and tune the efficiency of signal transmission between neurons with a high level of plasticity. …”

Electrochemical modification of electrodes with metal nanoparticles by Mavrokefalos, C

“…For the first time, this study contradicts the classical theories for electrochemical nucleation and growth which proceed only by the fresh reduction of ions. It demonstrates that electrochemical nucleation and growth at the early stages is overpotential dependent and in fact proceed also by the aggregation of small clusters through surface diffusion when deposited at relatively higher overpotentials. …”
