In this report the thermochemical conversion of Sm2O3 to SmCl3 using AlCl3 in LiCl-KCl melt at 773 K is discussed. The final product was a mixture SmCl3, Al2O3, unreacted and chloride melt. electrochemical attributes analyzed with cyclic voltammetry (CV) square wave (SWV). crystallographic phases were studied X-ray diffraction (XRD) technique. major chemical optimized by varying effective param...

The studies concern the effect of addition acid whey in combination with sodium ascorbate on selected parameters related to proteolysis uncured dry-fermented sausages. Four sausage samples (with different additives: curing mixture (C); sea salt (S); and liquid (SAW); salt, (SAWA)) were taken at day 0, 7, 14 21 ripening assess basic physicochemical properties, thiobarbituric acid-reactive substa...

Experimental hypertension studies are few in the hooded (Aguti) rat. The present study was designed to investigate the usefulness of this rat strain for experimental hypertension studies and to test the hypothesis that the hypertension may be associated with a diminution of endothelium dependent and independent relaxations. Hypertension was induced in inbred hooded rats (n=8 each) by administer...

Methods for the direct chiral chromatographic separation of the four stereoisomers of meta-hydroxyphenylpropanolamine (MHPA) on an analytical and preparative scale are described. Separations were carried out on a Crownpak CR (+) chiral column with 113 mM aqueous perchloric acid as the mobile phase. Baseline resolution of the more retained (+)-stereoisomers (1S configuration) and partial resolut...

In our study, we show by solid-state (15)N NMR measurements that an important zirconium metal-organic framework (UiO-66) with amino-functionalized links is composed of a mixture of amino and -NH(3)(+)Cl(-) salt functionalities rather than all amino functionality to give a composition of Zr(6)O(4)(OH)(4)(BDC-NH(2))(4)(BDC-NH(3)(+)Cl(-))(2) (UiO-66-A). UiO-66-A was postsynthetically modified to f...

Strains tentatively identified as Bacillus sp. were isolated from sewage sludge and soil and shown to elaborate extracellular enzymes that degrade the extracellular polysaccharide (xanthan gum, polysaccharide B-1459) of Xanthomonas campestris NRRL B-1459. Enzyme production by one strain was greatly enhanced when the strain was incubated in a mixed culture. Products of degradation were identifie...

The synthesis of furanic derivatives (5-hydroxymethylfurfural (HMF), furfural . . . ) from carbohydrates is of high interest for a wide range of applications. These reactions are carried out in the presence of various solvents, and among them choline chloride can be used. It is a salt that can form a low melting mixture with a carbohydrate (fructose, glucose . . . ) or a deep eutectic mixture w...

In 1937, Schrader, Prickett, and Salmon3 reported that rats fed on a diet low in potassium exhibited extensive pathologic changes in the intestine, pancreas, kidneys, and heart. Prior to this, Miller2 had reported that rats fed on a low potassium diet were abnormally "alert" and that growth was slow; Leulier and Vanhems' found that their animals survived only 12 to 24 days and did not grow. The...
