Olivine-type lithium metal phosphates (LiMPO₄) are promising cathode materials for lithium-ion batteries. LiFePO₄ (LFP) is commonly used in commercial Li-ion cells but the Fe3+/Fe2+ couple can be usefully substituted with Mn3+/Mn2+, Co3+/Co2+, or Ni3+/Ni2+, in order to obtain higher redox potentials. In this communication we report a systematic analysis of the synthesis condition of LiCoPO₄ (LC...

The ion atmosphere around nucleic acids is an integral part of their solvated structure. However, detailed aspects of the ionic distribution are difficult to probe experimentally, and comparative studies for different structures of the same sequence are almost non-existent. Here, we have used large-scale molecular dynamics simulations to perform a comparative study of the ion distribution aroun...

INTRODUCTION The aim of the study was to evaluate stability of 48 total parenteral admixtures for pediatric patients who require home parenteral nutrition. Admixtures contain high amounts of electrolytes. In a clinical practice electrolytes-enrichment of the parenteral nutrition admixtures is a usual demand, especially on the neonatal/pediatric wards. The supplementation of parenteral nutrition...

Incubation of purified recombinant human tau protein with aluminum salts at concentrations > or = 100 microM induces aggregation of tau that prevents its entry into SDS-polyacrylamide gels and filtration through nylon membranes. This effect is noncovalent and can be reversed by addition of EDTA. However, when incubated along with ATP, GTP, or CTP, aluminum catalyzes a covalent linkage that resu...

Sci., 20: 503-509 Marinating is commonly used method which involves injection, tumbling or immersion to disperse in the muscle tissue solutions contained water, salt and other ingredients. There are several types of marinating according to added solution ingredients. While a...

The equilibrium dissociation constant of the DNA binding domain of interferon regulatory factor 1 (IRF1 DBD) for its DNA binding site depends strongly on salt concentration and salt type. These dependencies are consistent with IRF1 DBD binding to DNA, resulting in the release of cations from the DNA and both release of anions from the protein and uptake of a cation by the protein. We demonstrat...

A critical appraisal of single-step extraction procedures of chromium species from soil was done in terms of their selectivity towards Cr(III) and Cr(VI) species. Samples of natural mineral and organic soil and samples of soil enriched with different chromium compounds of various solubility (in liquid or solid form) were used to simulate contamination of soil by liquid and solid wastes. The eff...

The application of calorimetric principles to the determination of phosphorus is especially desirable in view of the long drawn out and laborious gravimetric method now customarily employed. The accuracy of calorimetric methods, the ease with which most calorimetric procedures are carried on and their employment where only small amounts of material are available for analysis would make a reliab...

Greenwald and Lewman (1) described a method in which the protein and carbonic acid of blood are removed by picric acid, so that the alkali of the proteinates and bicarbonate is replaced by an equivalent of alkali picrate, which is measured. The picric acid precipitates the protein and frees the COZ, which is boiled off from the filtrate. The alkali picrate is measured as total picric acid minus...

Leifson (1936) reporting on the use of a selenite enrichment media for the isolation of typhoid and paratyphoid bacilli, pointed out several factors which affect the inhibitory properties of the selenium salts. Among these were the influence of phosphates, the composition of medium particularly in regard to the peptone used, and composition and concentration of the product examined. Unfortunate...
