comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولHumidity Sensing in Drosophila
Environmental humidity influences the fitness and geographic distribution of all animals [1]. Insects in particular use humidity cues to navigate the environment, and previous work suggests the existence of specific sensory mechanisms to detect favorable humidity ranges [2-5]. Yet, the molecular and cellular basis of humidity sensing (hygrosensation) remains poorly understood. Here we describe ...
متن کاملImpedance characteristics of thin films humidity sensing elements based on Bi - doped TiO 2
The paper proposes results from the investigations of humidity sensing elements based on Bi-doped TiO 2 thin films, prepared by a sol-gel method. Titanium n-butoxide was used as a starting material for the preparation of the experimental samples, and bismuth acetate as doping compound. The samples were sintered at 400°C. Afterwards, the samples were placed into a calibrated humidity chamber and...
متن کاملBiochars as Innovative Humidity Sensing Materials
In this work, biochar-based humidity sensors were prepared by drop-coating technique. Polyvinylpyrrolidone (PVP) was added as an organic binder to improve the adhesion of the sensing material onto ceramic substrates having platinum electrodes. Two biochars obtained from different precursors were used. The sensors were tested toward relative humidity (RH) at room temperature and showed a respons...
متن کاملSynthesis, Humidity Sensing, Photocatalytic and Antimicrobial Properties of Thin Film Nanoporous PbWO4-WO3 Nanocomposites
A humidity sensor thin film based on nanoporous PbWO4-WO3 composites has been prepared by spin coating technique with different weight ratio of PbWO4 (Pb) and WO3 (WO) (PWWO-01, PWWO-82, PWWO-64, PWWO-46, PWWO-28, PWWO-01) and their humidity sensing properties have also been investigated at different relative humidity (RH) in the range of 5% - 98% at room temperature with dc resistance. It is f...
