Abstract We have obtained conducting inks through the hybridization of indium tin oxide (ITO) and polypyrrole. Different conductive were at different ITO loadings. The zeta potentials polypyrrole-ITO investigated as functions pH solution. exhibited zero potential approximately = 5, varied with solution, which also significantly depended on range. Thermogravimetric analysis was performed to inve...

Through a catalyst- and transfer-free process, we fabricated indium tin oxide (ITO)-free organic solar cells (OSCs) using a carbon nanosheet (CNS) with properties similar to graphene. The morphological and electrical properties of the CNS derived from a polymer of intrinsic microporosity-1 (PIM-1), which is mainly composed of several aromatic hydrocarbons and cycloalkanes, can be easily control...

Given two k-independent sets I and J of a graph G, one can ask if it is possible to transform the one into the other in such a way that, at any step, we replace one vertex of the current independent set by another while keeping the property of being independent. Deciding this problem, known as the Token Jumping (TJ) reconfiguration problem, is PSPACE-complete even on planar graphs. Ito et al. p...

Thin metal film stands out as a promising indium tin oxide (ITO)-free transparent conductor, by its good optoelectronic performance, excellent mechanical flexibility, and simple fabrication process. In their Review (article number 2001298), Cheng Zhang, L. Jay Guo co-workers discuss the past progress future challenges of ITO-free conductors that are based on thin films. This comprehensive revie...

Polymer solar cells have shown good prospect for development due to their advantages of low-cost, light-weight, solution processable fabrication, and mechanical flexibility. Their compatibility with the industrial roll-to-roll manufacturing process makes it superior to other kind of solar cells. Normally, indium tin oxide (ITO) is adopted as the transparent electrode in polymer solar cells, whi...

in this paper, indium tin oxide (ito) nanoparticles has been prepared by chemical methods under given conditions with solution of indium chloride (incl3·4h2o), tin chloride (sncl4·5h2o) in ammonia solution. the samples were characterized by x-ray diffraction (xrd) and scanning electron microscopy (sem) analyses after heat treatments. the sem results showed that, the size of the ito particles pr...

In 1984 Bannai and Ito conjectured that there are finitely many distance-regular graphs with fixed valencies greater than two. In a series of papers, they showed that this is the case for valency 3 and 4, and also for the class of bipartite distance-regular graphs. To prove their result, they used a theorem concerning the intersection array of a triangle-free distance-regular graph, a theorem t...

The origin of plasma-induced damage on a p -type wide-bandgap layer during the sputtering of tin-doped indium oxide (ITO) contact layers by using radiofrequency-superimposed direct current (DC) sputtering and its effects on the forward voltage and light output power (LOP) of light-emitting diodes (LEDs) with sputtered ITO transparent conductive electrodes (TCE) is systematically studied. Changi...
