Rajitha, Kamalon published the artcileSynthesis of graphene oxide-based nanofillers and their influence on the anticorrosion performance of epoxy coating in saline medium, COA of Formula: C13H10N2S, the publication is Diamond and Related Materials (2020), 107974, database is CAplus.

The present study investigated the anticorrosion performance of epoxy coating by the incorporation of two different functionalized graphene oxides as nanofillers in saline media. GO was functionalized with 2-aminothiazole (AT) and 2-amino-4-(1-Naphthyl)Thiazole (ANT) and modified compounds were characterized by X-ray diffraction (XRD), Fourier transform IR spectroscopy (FT-IR), Thermogravimetric anal. (TGA), Raman spectroscopy, and SEM. 0.2 Weight% of neat epoxy and epoxy nanocomposites (GO-AT/EP and GO-ANT/EP) were coated on mild steel substrate by a spin coating method and the formation of a protective film on the steel surface was confirmed using SEM, Atomic Force Microscopy (AFM) and contact angle test. The electrochem. impedance spectroscopy was employed to study the corrosion protection properties of nanocomposite coatings in 3.5% NaCl medium. The results signify the better anticorrosion performance of nanocomposite coatings due to their two-dimensional sheet structures, uniform dispersion and exfoliation in the epoxy matrix, hydrophobic nature and stopping up tiny pores properties. The GO-ANT/EP coating exhibited higher coating resistance (6.598 x 107 Ω cm²) than GO-AT/EP (1.017 x 105 Ω cm²) and pure epoxy (1270 Ω cm²) coating. The crowded structure of GO-ANT helps in forming highly crosslinked compact epoxy coating and therefore displays excellent corrosion protection efficiency than other coatings.

Chloroacetylation of I (R = H) followed by substitution with morpholine and piperidine gave I (R = morpholinoacetyl, piperidinoacetyl). Cycloaddition of I (R = H) with HSCH₂CO₂H yielded thiazolidinone derivatives II. I and II have satisfactory fungicidal activity against Curvularia at 500 ppm. The mass spectra of I (R = H) were discussed.

Keil, Oliver published the artcileHyphenation of capillary high-performance liquid chromatography with matrix-assisted laser desorption/ionization time-of-flight mass spectrometry for nano-scale screening of single-bead combinatorial libraries, Computed Properties of 92-36-4, the publication is Rapid Communications in Mass Spectrometry (2002), 16(8), 814-820, database is CAplus and MEDLINE.

This paper focuses on the tech. aspects of chem. screening from 384-well plate nano-scale single-bead combinatorial libraries. The anal. technique utilized is a combination of capillary liquid chromatog. with UV detection and matrix-assisted laser desorption/ionization (MALDI) mass spectrometry. The HPLC/MALDI-MS hyphenation is achieved by means of a micro-fraction collector with a peak detection system that automatically collects the peaks onto the MALDI targets for subsequent characterization. Several exptl. parameters such as type of 384-well plate, well-plate sealing foils, and a column-switching procedure were investigated using a small test library of nine components. Addnl., the influence of different MALDI matrixes, different MALDI targets and sample-spotting techniques on the MALDI detection sensitivity as well as the ruggedness and sample throughput capacity of this technique were studied. Optimum results for the analytes investigated were obtained with 2,5-dihydroxybenzoic acid using online mixing of HPLC effluent and matrix solution To demonstrate the potential of this capillary HPLC/MALDI-TOFMS method, its application to several single-bead libraries was investigated. The instrumental method allowed for the rapid identification and purity assessment of combinatorial libraries with detection limits down to the higher femtomole level using both UV detection and MALDI mass spectrometry.
