“…It is possible to model the band structures, electron effective masses and mobilities in this way. 69 AZOs have been synthesised by a number of means including atmospheric-pressure (thermal) chemical vapour deposition, 72 RF and DC magnetron sputtering, 78,79 atomic layer deposition, 80 pulsed laser deposition, 81 sol-gel 82 and spray pyrolysis techniques. Still, the error appears to be systematic, meaning this remains a useful tool for comparative screening of materials at the early stages.…”

This article focuses on n-type doped transparent conducting binary oxides -namely, those with the general formula M x O y :D, where M x O y is the host oxide material and D is the dopant element. Such materials are of great industrial importance in modern materials chemistry. In particular, there is a focus on the search for alternatives to indium-based materials, prompted by indium's problematic supply risk as well as a number of functional factors. The important relationship between computational study and experimental observation is explored, and an extensive comparison is made between the electrical properties of a number of the most interesting experimentally-prepared materials. In writing this article, we aim to provide both an accessible tutorial of the physical descriptions of transparent conducting oxides, and an up-to-date overview of the field, with a brief history, some key accomplishments from the past few decades, the current state of the field as well as postulation on some likely future developments.

“…In order to enhance these properties ZnO should be doped with various dopants. Doping of ZnO with Al, In and Ga were widely investigated by various group of researchers [6][7][8] and it resulted in ntype conductivity. In the present study bismuth (Bi) has been selected as the doping element.…”

“…The O1s peak can be decomposed into three components, centered at 530.4 ± 0.1 eV, 531.6 ± 0.1 eV and 536.1 ± 0.1 eV, and are defined by Gaussian fitting O I , O II and O III . The lower binding energy O I peak (530.4 eV) can be ascribed to the O 2− ion on the wurtzite ZnO structure, which is surrounded by Zn atoms and forms a fully complementary state with the surrounding adjacent O 2− ions [ 32 , 33 ]. The O II peak at intermediate binding energy (531.6 eV) is correlated with the O 2− ions in the oxygen-deficient region of the ZnO matrix [ 33 ].…”

The intensity of the component further reflects the concentration of oxygen vacancies, which can be assigned to the Zn-O bond and adsorbed oxygen including physically adsorbed or chemisorbed oxygen and hydroxides within the surface layer, respectively [ 34 , 35 , 36 ].…”

Mitochondrial membrane potential regulation through the mitochondrial permeability transition pore (mPTP) is reportedly involved in the ischemic postconditioning (PostC) phenomenon. Melatonin is an endogenous hormone that regulates circadian rhythms. Its neuroprotective effects via mitochondrial melatonin receptors (MTs) have recently attracted attention. However, details of the neuroprotective mechanisms associated with PostC have not been clarified. Using hippocampal CA1 pyramidal cells from C57BL mice, we studied the involvement of MTs and the mPTP in melatonin-induced PostC mechanisms similar to those of ischemic PostC. We measured changes in spontaneous excitatory postsynaptic currents (sEPSCs), intracellular calcium concentration, mitochondrial membrane potential, and N-methyl-D-aspartate receptor (NMDAR) currents after ischemic challenge, using the whole-cell patch-clamp technique. Melatonin significantly suppressed increases in sEPSCs and intracellular calcium concentrations. The NMDAR currents were significantly suppressed by melatonin and the MT agonist, ramelteon. However, this suppressive effect was abolished by the mPTP inhibitor, cyclosporine A, and the MT antagonist, luzindole. Furthermore, both melatonin and ramelteon potentiated depolarization of mitochondrial membrane potentials, and luzindole suppressed depolarization of mitochondrial membrane potentials. This study suggests that melatonin-induced PostC via MTs suppressed the NMDAR that was induced by partial depolarization of mitochondrial membrane potential by opening the mPTP, reducing excessive release of glutamate and inducing neuroprotection against ischemia-reperfusion injury.
