In this research, the effect of PEO procedure time on the distinct properties of coatings such as morphology, chemical composition, roughness and corrosion has been studied. A scanning electron microscopy equipped with an energy dispersive spectroscopy was used to study the microstructure of the coatings. In addition, x-ray diffraction (XRD) and roughness meter were used to evaluate the chemica...

Phenothiazines belong to the oldest, synthetic antipsychotic drugs, which do not have their precursor in the world of natural compounds. Apart from their fundamental neuroleptic action connected with the dopaminergic receptors blockade, phenothiazine derivatives also exert diverse biological activities, which account for their cancer chemopreventive-effect, as: calmodulin- and protein kinase C ...

Partially coating perpendicularly aligned carbon nanotube arrays with an appropriate polymer thin film along their tube length provides a novel concept for developing new sensors of high sensitivity, good selectivity, and excellent environmental stability for the detection of a broad class of chemical vapors with low power consumption. The absorption and desorption of chemical vapors by the pol...

Resistance of diamondback moth (DBM) to insecticides in Southeast Asia remains notorious despite repeated efforts by the chemical industry and academia to manage it. New insecticides continue to lose their efficacy a few seasons after their introduction for use. Scientific knowledge on the DBM resistance profile and resistance mechanisms in the literature is voluminous. However, there is still ...
