A photo-radiation method was applied to decompose oxalate precipitates so that it can be dissolved into dilute nitric acid. This work has been studied as a part of partitioning of minor actinides. Minor actinides can be recovered from high-level wastes as oxalate precipitates, but they tend to be coprecipitated together with lanthanide oxalates. This requires another partitioning step for mutua...

This work contains the results of studies on the influence of new lysosomotropic substances on an erythrocyte membrane. The compounds studied were hydrochlorides of N,N-dimethylglycine alkyl esters (DMG-n) and N,N-dimethylalanine alkyl esters (DMAL-n) having two different-length alkyl chains (n = 12 and 16), oxalates of dimethylaminoalaninates (DMAL s -n; n = 8, 10, 12, 14 and 16) and methobrom...

Total, soluble and insoluble oxalates were extracted and analyzed by high performance liquid chromatography (HPLC) following the preparation of kimchi using silver beet (Beta vulgaris var. cicla) stems and leaves. As silver beet contains high oxalate concentrations and consumption of high levels can cause the development of kidney stones in some people, the reduction of oxalate during preparati...

Organic salts, such as Fe, Ca, and Mg oxalates acetates, may be widespread radiolysis oxidation products of organic matter in Martian surface sediments. Such salts are challenging to identify by evolved gas analysis but the ubiquitous CO2 CO pyrolysis data from Sample Analysis at Mars (SAM) instrument suite on Curiosity rover indirectly points their presence. Here, we examined laboratory result...

Crystalline and nanostructured cobalt (CoFe2O4), nickel (NiFe2O4), zinc (ZnFe2O4) and manganese (MnFe2O4) spinel ferrites are synthesized with high yields, crystallinity and purity through an easy, quick, reproducible and low‐temperature hydrothermal assisted route starting from an aqueous suspension of coprecipitated metal oxalates. The use of water as a reaction medium is a further adva...

The relationship between the product patterns and the configurations of 1,2-cycloheptane- and 1,2-cyclooctanediols 9 in the cyclocondensations with oxalyl chloride in the presence of triethylamine at 0 degrees C has been shown analogous to that obtained for 1,2-disubstituted acyclic ethylene glycols 1: cis-1,2-cyclooctanediol (9f) produced the cyclic oxalate 14f as the major product, while tran...

The intake of foods derived from plants has been proposed as an useful strategy in the prevention several chronic diseases. However, also possess a group substances known antinutrients, which may be responsible for deleterious effects related to absorption nutrients and micronutrients, or exert beneficial health effects. This review compiles scientific evidence regarding physiological impact so...
