In this paper, we have proposed a simple method to covalently conjugate biotin to magnetic nanoparticles, which can be targeted to the tumour sites by using pretargeting approach with avidin or streptavidin. Magnetic nanoparticles of manganese ferrite were synthesized by alkaline coprecipitation of ferric chloride hexahydrate, ferrous sulphate heptahydrate and manganese sulphate monohydrate usi...

In a previous paper (Loureiro a Janz, 1942) we compared the iodometric and oxalic acid titres of permanganate solutions under various conditions, and verified that the values obtained in titrating small samples of oxalic acid in the usual way in hot dilute acid solution may differ appreciably from those yielded by the permanganate-iodide-thiosulphate reaction. This merely confirms a well-known ...

The influence of surfactants (anionic sodium dodecyl sulfate, and nonionic tert-octylphenol ethoxylate with 9.5EO) and their mixtures on the adsorption of carboxymethylcellulose (CMC) in the presence of 0.001 M NaCl on the manganese dioxide surface (MnO(2)) was studied. The increase in CMC adsorption was observed in all measured systems in the presence of surfactants. The reason for this is the...

We measured the solubility of apolipoprotein E (apo E) after precipitation, with heparin-Mn2+ or dextran sulfate-Mg2+, of lipoproteins containing apo B. Data from 46 randomly selected subjects suggest that apo E is readily precipitated by dextran sulfate-Mg2+, but that heparin-Mn2+ preferentially precipitates apo E associated with apo B-containing lipoproteins while leaving the apo E-containing...

In an attempt to search for mixed alkaline-earth and transition metal pyroborates, the title compound, barium manganese(II) pyroborate, has been synthesized by employing a flux method. The structure of BaMnB2O5 is composed of MnO5 square pyramids that form Mn2O8 dimers by edge-sharing and of pyroborate units ([B2O5]4-) that are composed of two corner-sharing trigonal-planar BO3 units. These bui...

Ocean Drilling Program Leg 201 was the first ocean drilling expedition dedicated to the study of life deep beneath the seafloor. Its seven sites were selected to represent the general range of subsurface environments that exist in marine sediments throughout most of the world’s oceans. In water depths as great as 5300 m and as shallow as 150 m, the expedition drilled as deep as 420 m into ocean...

Manganese oxide-supported palygorskite (MnOx/PG) catalysts are considered highly efficient for low-temperature SCR of NOx. However, the MnOx/PG catalyst tends to be poisoned by SO2. The effect SO2 on activity SO2-pretreated poisoning under ammonia-free conditions was explored. It determined that considerably deactivated in absence ammonia and water-washed regeneration can completely recover cat...

The crucial role of manganese(III) species in the oxidative and catalytic reactivity manganese oxides have been widely reported. However, direct activation radical precursors by Mn(III) is still a matter discussion. In this work, ability Mn(III)-bearing oxide (Mn2O3) for peroxydisulfate (PS) peroxymonosulfate (PMS) was evaluated compared using caffeine (CAF) as model pollutant. Complete CAF rem...

Electrolytic manganese residue (EMR) contains a large number of soluble ions and ammonia nitrogen, which seriously endangers the surrounding environment. Solidifying removing nitrogen has become primary method for controlling EMR. In this study, an EMR stacking yard in Guangxi was used as study site to solidification removal by mixed bacteria under natural conditions. Further, Illumina MiSeq hi...
