this research evaluates the efficiency of nanosized zno in the catalytic ozonation of 4-chloro-2-nitrophenol and determines the effect of ph on heterogeneous catalytic ozonation. the combined use of ozone and zno catalyst leads to conversion of 98% 4-chloro-2-nitrophenol during 5 min. in addition, it was found that in zno catalytic ozonation, the degradation efficiency of 4-chloro-2-nitrophenol...

In this work, the insulating properties of poly(4-vinylphenol) (PVP) and SU-8 (MicroChem, Westborough, MA, USA) dielectrics are analyzed and compared with each other. We further investigate the performance behavior of organic field-effect transistors based on a semiconducting liquid-crystal polymer (LCP) using both dielectric materials and evaluate the results regarding the processability. Due ...

In a collaboration between Pennsylvania State University and Princeton University, we have been laying the foundations for flexible display technology. Flexible substrates including plastic or steel foil, backplanes of organic or silicon transistors, and directly printed RGB organic light emitting diodes are issues central to this collaboration. We present an overview of key recent results. Sil...

Mechanical buckling usually means catastrophic failure in structural mechanics systems. However, controlled buckling of thin films on compliant substrates has been used to advantage in diverse fields such as micro-/ nanofabrication, optics, bioengineering, and metrology as well as fundamental mechanics studies. In this Feature Article, a mechanical buckling model is presented, which sprang, in ...

The purpose of this study was to develop and implement an in silico model of indigoid-based single-electron transistor (SET) nanodevices, which consist of indigoid molecules from natural dye weakly coupled to gold electrodes that function in a Coulomb blockade regime. The electronic properties of the indigoid molecules were investigated using the optimized density-functional theory (DFT) with a...

Organic thin-film transistors (TFTs) are of interest for flexible, large-area electronics applications, such as rollable or foldable information displays, conformable sensor arrays, and plastic circuits [1]. The vast majority of the organic TFTs that have been developed to date are p-channel TFTs, meaning that the electric currents in these transistors are due to the flow of positive charge car...
