“…Thus, the fabrication temperature is limited to %100 °C or lower on PET substrate. [11,12] In the fabrication of the thin-film semiconductor layer, the low-temperature fabrication process is required in order to realize flexible transistors on PET substrate. Conjugated polymer materials having high mobility require high thermal anneal temperature.…”

We have fabricated flexible organic thin film transistors with liquid crystalline organic semiconductor, 2‐decyl‐7‐phenyl‐benzothienobenzothiophene (Ph‐BTBT‐10), which is suitable for flexible transistor material because the polycrystalline thin films can be easily fabricated at about 100 °C or lower by solution process. 25 μm thick polyethylene terephthalate (PET) film and photosensitive resin poly(vinyl cinnamate) (PVCi) are used as flexible substrate and gate insulator, respectively. The PVCi gate insulator layer is crosslinked by UV light and the crosslinking reaction increases solvent resistance of PVCi gate insulator. Uniform Ph‐BTBT‐10 polycrystalline thin films are fabricated on the PVCi gate insulator and the crystallinity and electrical characteristics of Ph‐BTBT‐10 are not damaged by PVCi gate insulator. The entire process is performed below 130 °C considering the heat resistance temperature of the PET film. The fabricated transistors show the mobility of 0.24±0.084 cm2V−1s−1 and threshold voltage of 0.57±0.38 V.This article is protected by copyright. All rights reserved.

“…Due to its high solubility, underground water sources and even drinking water are easily contaminated with cyanide, and this results from various anthropogenic activities like metal mining processes, electroplating, manufacturing of petrochemical and pharmaceutical products and plastic burning. [4,5] By reason of its high toxicity, the World Health Organization (WHO) and the European Union have respectively set the maximum allowable limit in drinking water as 70 and 50 μg/L. [6] Exposure of humans to cyanide may occur through ingestion, inhalation or via skin absorption, and these exposures could lead to health effects such as vertigo, partial blindness, headache and paresis.…”

Cyanide (CN−) is known to be a very harmful ion that may accumulate in the air, soil and water, and become a critical risk to organisms, even at trace levels. Hence, it is very critical to develop sensitive and accurate analytical methods for the determination of this anion. In this study, a highly sensitive and simple approach was developed for the quantitative determination of cyanide by UV‐Vis spectrophotometry with the aid of synthesized silver nanoparticles (AgNPs) solutions. AgNPs are promising probes frequently used in the determination of both organic and inorganic pollutants. The AgNPs were prepared by reducing silver nitrate (AgNO3) with sodium borohydride (NaBH4) in the presence of Triton X‐100 as a stabilizer. The UV‐Vis absorption spectra showed that the interaction between cyanide ions and AgNPs made significant decreases in the absorption peak of the surface plasmon resonance (SPR) band at 405 nm. The developed colorimetric sensor exhibited exceptional sensing towards cyanide ions with good linearity in the range of 0.5 and 3.5 mM. The limit of detection (LOD) and the limit of quantification (LOQ) were estimated as 0.09 and 0.29 mM, respectively. Moreover, the proposed colorimetric method was successfully applied to different water samples.
