Magnetocaloric effect (MCE) and heat capacity during the magnetization of (5,10,15,20-tetrakis(3,5-di-tert-butyl-4-hydroxyphenyl)porphynato) manganese (III) chloride (1), (5-(4-hydroxyphenyl)-10,15,20-tris(3,5-di-tert-butyl-4-hydroxyphenyl)porphynato) manganese (III) chloride (2), and (5-(4-palm...
The iron and cobalt(II) clathrochelates were functionalized with one, two and six 2,6-di-tert-butylphenolsulfide and phenylsulfide ribbed substituents by nucleophilic substitution of their chlorine-containing clathrochelate precursors. The cycloaddition of the corresponding phenol-containing α-...
This study unveils the in vitro and in vivo antibiofilm potential of 2,6-Di-tert-butyl-4-methylphenol (DTBMP) from Chroococcus turgidus against Vibrio spp. In the preliminary study, cell free culture supernatant (CFCS) of C. turgidus inhibited the violacein production in biomarker strain Chromob...
The reaction of [(Dpp-Bian)AlH(THF)] (I) (Dpp-Bian = 1,2-bis[(2,6-diisopropylphenyl)imi-no]acenaphthene) with 1,3-dicyclohexylcarbodiimide (DCC) is accompanied by reduction of the carbodiimide C=N bond giving the complex [(Dpp-Bian)Al(DCC(H))] (II). In the reaction of hydride I with 2,6-di-tert-...
Radiation-induced destruction of the ionol molecules in liposomes built of L-α-lecithin depends on the ionol concentration in the lipids and on the concentration of the lipid in the dispersion.
Transformer oils were analyzed at different service times by IR spectrometry and by a kinetic method using a model reaction of initiated cumene oxidation. The concentrations of an antioxidant additive (ionol) and the degrees of formation of new oxidation inhibitors in transformer oils can be dif...
Technologically simple and low-cost method is suggested for processing of wastes from manufacture of ionol, a resin from the rectification stage, by isolation of 4,4′-ethylenebis(2,6-di- tert -butylphenol) via dissolution in hexane with the subsequent crystallization. A high activit...
Eltanolone is the lipid emulsion formulation, for intravenous use, of the steroid anaesthetic 5-β-pregnanolone. We have screened this agent in malignant hyperthermia susceptible (MHS) Landrace swine to assess its potential to trigger the Malignant Hyperthermia (MH) syndrome in MHS subjects or t...
A high-performance liquid chromatographic method for the determination of eltanolone in plasma has been developed. Plasma samples containing eltanolone were diluted with acetonitrile to precipitate plasma proteins, and derivatized with 2,4-dinitrophenylhydrazine before direct injection onto a C ...
Changes in the expiratory dimensions of the rib cage and abdomen on induction of anaesthesia with eltanolone, propofol and thiopentone were measured in 76 patients using respiratory inductance bands. Calibration of the respiratory inductance plethysmograph was by simultaneous flow measurement wi...
Behavior of cubic spinel phase of Ag 2 MoO 4 is investigated at high pressure using X-ray diffraction and Raman spectroscopy. The P–V data are fitted to a third order Birch–Murnaghan equation of state using a value of B 0 =113GPa and B′ 0 =4. The compound is al...
Chitin gel-membranes (CGM), which fabricated directly from chitin solution in NaOH/urea aqueous system at low temperature, were applied for in situ synthesis of Ag 2 Mo 2 O 7 nanoparticles to obtain hybrid nanomaterials. The microporous structure of CGM at wet state was s...
Ag2MoO4 ceramic was prepared by using the solid‐state reaction method, which could be sintered at 450°C for 2 h, having a relative permittivity of 8.08, a Qf value of 17 000 GHz, and a temperature coefficient of resonance frequency about −133 ppm/°C. Ag2MoO4 ceramic was chemically compatible ...
The conductivity relaxation in the frequency range from 10 Hz to 2 MHz and in the temperature range from 108 to 303 K for the fast ion conducting AgI–Ag 2 O–MoO 3 glasses has been reported. It has been observed that the conductivity relaxation in these glasses is highly non-exp...
Glass-nanocomposites in the system Ag 2 S–Ag 2 O–MoO 3 have been synthesized by quenching of melts. Microstructural studies of the samples have been accomplished using X-ray diffraction, high-resolution transmission electron microscopy and field emission scanning electr...
