Extensive application of silica nanoparticles (SNPs) in various industrial products has led to the development of silica extraction methodologies out of various waste products. Rice husk is an agricultural waste with a high content of amorphous silica. However, the presence of metal ion impurities and unburned carbon in the rice husk content may present an adverse effect on product color and pu...

A novel liquid argon (LAr) purity monitor was developed with a sensitivity to elec-tronegative impurities of the order of ppb (O 2 equivalent). Such a high purity is e.g. needed in a LAr drift chamber. The principle is to measure the lifetime of quasifree electrons in LAr, since this is the important parameter for the operation of a drift chamber. Free electrons are produced by ionizing the LAr...

in this paper a fast and novel stability-indicating ultra fast lc method for separation and estimation of impurities in clopidogrel and aspirin in their combined tablet dosage form and omeprazole was developed. the separation of usp related substances of clopidogrel (a, b and c), aspirin (d), omeprazole (a, b and c) and few other unknown impurities was detected by using ultra fast liquid chroma...

conclusions taken together, pomegranate juice did not affect serum cytokines levels in patients with oa. its role in improving physical function in these patients most likely involves other mechanisms. background osteoarthritis (oa) is the most common musculoskeletal disorder causing disability and loss of function, particularly in the elderly. preclinical and in-vitro studies for mitigation of...

Mahanarva fi mbriolata (Stål) is an important pest in Latin America and causes signifi cant reduction in sugarcane productivity. There is no information regarding the effect of this pest on the quality of cane juice used for sugar and alcohol production. This work aimed at evaluating the quality of sugarcane juice from plants attacked by spittlebugs. The experiment was arranged in a completely ...

Peptides are becoming an important class of molecules in the pharmaceutical field. Closely related peptide-impurities in peptides are inherent to the synthesis approach and have demonstrated to potentially mask biomedical experimental results. Quorum sensing peptides are attracting high interest in R&D and therefore a representative set of quorum sensing peptides, with a requested purity of at ...

This paper reports the results of an investigation of the effects of purity level and nature of impurities on the properties of recycled polycarbonate and recycled acrylonitrile-butadiene-styrene polymers blended with the corresponding virgin resins. The relevant thermal, mechanical and flow properties were measured. It is concluded that properties of recycled polymers depend not only on the am...

Union Co-operative Limited has historically had a problem with the mixed juice purity bcing lower than the direct analysis of cane pul-ity, indicating sucrose loss. Tests wcrc conducted to identify the cause. Based on this work, blocides have been dosed in recent ycars, resulting in the mixed juice purity becoming higher than the dircct analysis of cane pusty. This indicates reduccd losses in t...

Supercritical fluid extraction analyses are often compromised by trace impurities present in the solvent carbon dioxide. These impurities, commonly used as lubricants in the specialty gas industry, can produce significant background levels, increasing limits of detection and quantification. This problem is especially severe when electron capture detection (ECD) is used for trace concentrations ...

exploitation of the full potential of any hybrid requires the possessing of genetically high-purity seeds. commercial soybean hybrids have been developed using a cytoplasmic male sterility (cms) system. in order to avoid reduction in yield caused by using low-purity seeds, development of a simple, rapid, and accurate method for hybrid purity assessment is of great essence and significance. ther...
