Sulfamethoxazole (SMX) is a widespread and persistent antibiotic pollutant in the aquatic environment. In this paper, SMX was degraded by gamma irradiation, and various influencing factors were explored. The experimental results revealed that after 1.5 kGy irradiation, 20 mg/L SMX could be compl...

The present work describes the synthesis and spectroscopic characterization of ten different metal complexes of sulfabenzamide and sulfamethoxazole as ligands (M-SBZ, M-SMZ). Spectroscopic methods such as 1H NMR, UV-Vis spectroscopy analysis, FTIR and XRD confirmed the coordination of both ligan...

Microplastics and sulfamethoxazole (SMX) are ubiquitous in aquatic environment. In this study, we investigated the sorption of SMX onto six types of microplastics (polyamide (PA), polyethylene (PE), polyethylene terephthalate (PET), polystyrene (PS), polyvinyl chloride (PVC) and polypropylene (P...

A short and efficient route for the synthesis of aminoalkyl 8-aminoadenylates, potential aminoacyl-tRNA synthetase inhibitors, is presented. Aminoalkyl 8-aminoadenylates were synthesized using a 5′-H-phosphonate strategy involving minimal protecting group manipulations and a single final deprot...

Thermal decomposition of catalytically-inert iodotrimethylplatinum(IV) tetramer in the presence of olefin and organosilicon hydride substrates leads to soluble platinum catalysts that actively promote hydrosilation. Characterization of the complexes formed on tetramer decomposition and their rel...

The infrared spectra from 4000 to 30 cm-1 and the Raman sperm of chloro-, bromo- and iodotrimethylplatinum(IV) in the solid state have been recorded and qualitative assignments made. Very strong Raman lines at 581, 574 and 560 cm−1 are assigned to PtC stretching vibrations in the three compounds...

The preparation and antigenic properties of three different types of estradiol 17-glucuronide-bovine serum albumin (BSA) conjugates in which the haptens are linked to the carrier protein through the C-2 (or C-4) position have been described. All antibodies raised against these antigens in rabbit...

17α-estradiol 17-N-acetylglucosaminide (17αE2 17NAG) is an estrogen metabolite hitherto obtained only in rabbits. To gain insight into this unique conjugate, an enzyme immunoassay (EIA) was established by using antiserum elicited against 3-[3-(1-carboxypropyl)] ether of 17αE2 17NAG-bovine ser...

The coordination structures of the nickel(II) complexes of 4-ethyl-a-pheneyl-1,3-octadione (denotes A) formed upon solvent extraction from ammoniacal media have been investigated. The combination analysis of their X-ray absorption spectroscopy with IR, UV–Vis and NMR spectroscopies provides a m...

ZnO nanoparticles of different sizes, from 20 to 200 nm in length, and morphologies, nanorods and coral-like structures, were synthesized via a simple one-pot synthesis by refluxing an oversaturated solution of zinc acetylacetonate hydrate in 1-butanol and isobutanol.On the basis of 1H and 13C N...

We report synthesis, spectroscopic characterization, and thermal analysis of zinc acetylacetonate complex adducted by nitrogen donor ligands, such as pyridine, bipyridine, and phenanthroline. The pyridine adducted complex crystallizes to monoclinic crystal structure, whereas other two adducted c...

The chemical generation of atomic iodine using a chemical combustor to generate the atomic fluorine intermediate, from the reaction of F2 + H2, followed by the production of atomic iodine, from the reaction of F + HI, was investigated. The maximum conversion efficiency of HI into atomic iodine w...

Experimental results of the hyperfine structure (hfs) constants of levels of the iodine atom are reported. The absorption spectra of 50 transitions in the near infrared spectral region were observed using concentration modulation technique with a tunable single-mode cw Ti:Sapphire laser. Magneti...

We report the hyperfine Structure (hfs) splitting observations of neutral iodine atom (II) in the 6000 – 10,000 cm−1 near infrared spectral region. The measurements were carried out using a high-resolution Fourier Transform Spectrometer (FTS), where an electrodeless discharge lamp (EDL), excite...

The formation energies, diffusion barriers, vibration frequencies of complex iodine defects in 3C-SiC are calculated. The effective diffusion rates of these complex defects are evaluated in the temperature range from 300 K to 2000 K. The iodine interstitial diffusion is the dominant diffusion me...

Samarium is a rare-earth metal with several applications in materials science.
