To date, the foremost challenge for developing a new nanolubricant is particle suspension. Numerous NPs have recently been investigated for use as oil additives. Nanopowders of some metals and their compounds exert an especially effective influence on the characteristics of lubricants. The use of NPs that include Ni, Cu, Fe, TiO2 and other metallic NP additives in lubricating oils provides good friction reduction and anti-wear behavior. In this paper, we described the preparation of nickel nanopowders by the method of the electrical explosion of wire and their tribological performance as additives in oils. The obtained nickel nanopowders were investigated by the methods of scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD). The results of the investigation by SEM and TEM showed that the average diameter of these nanopowders is equal to 55.5 nm and their shape is spherical. Results of XRD investigation showed that nickel nanopowder has a pure fcc phase. The four-ball test results indicate that nickel nanopowders are potential additives for lubricating oils, and the tribological performance of lubricating oils can be improved significantly by dispersing nickel nanopowders in oils. Studies of tribotechnical properties have shown that the SAE-30 with nickel additives at concentrations of 0.4 wt. % has the best anti-wear properties in comparison with pure oil and other concentrations of nickel additive. The wear spot diameter has been reduced from 0.73 mm to 0.40 mm. The relative percentage of the friction coefficient has decreased by 47 percent
Dataset for transcriptome analysis of abscisic acid degrading bacterium Novosphingobium sp. P6W
Β© 2019 The Author(s) Plant growth-promoting rhizobacteria (PGPR) improve plant productivity and stress resistance. The mechanisms involved in plant-microbe interactions include the modulation of plant hormone status. The Novosphingobium sp. strain P6W was previously described as the bacterium capable of abscisic acid (ABA) degradation, and its inoculation decreased ABA concentrations in planta. The metabolic pathway for the ABA degradation in bacteria is still unknown. Here we present transcriptome data of Novosphingobium sp. P6W grown in the medium supplemented with ABA or fructose as the carbon source. Cleaned FASTQ files for the RNA-seq libraries are deposited in the NCBI Sequence Read Archive (SRA, Identifier: SRP189498) and have been assigned BioProject accession PRJNA529223
Comparative Study of the Abscisic Acid Metabolism Using Analogue Tritium-Labeled in the Cyclohexene or Side Moiety
Β© 2020, Pleiades Publishing, Ltd. Abstract: A procedure was developed for introducing tritium into the side chain of the abscisic acid (ABA) molecule. The reaction was carried out in dioxane in the presence of the Lindlar catalyst. The yield of the labeled product was 70% and the molar radioactivity was 44 Ci/mol. The tritium-labeled abscisic acid analogue was found to be a growth substrate for soil bacteria that incorporate a radioactive label into cellular metabolites. The absorption of the label by bacteria from the side chain of abscisic acid is more than an order of magnitude higher than that for labeling in the cyclohexene moiety. The results indicate the existence of a previously unknown metabolism pathway of ABA in microorganisms
