Besides maintaining homeostasis with respect to metals including iron, copper, manganese, and zinc (which play a fundamental role in numerous intracellular processes such as enzyme catalysis, protein folding, and signaling), microorganisms in deep-sea sediments of the polymetallic nodule province have to...
A previous study in female dugongs ana- lyzed elements in the 55 annual incremental longitudinal sections of tusks, and reported the presence of nine elements: barium (Ba), lithium (Li), sodium (Na), calcium (Ca), iron (Fe), magnesium (Mg), phosphorus (P), strontium (Sr) and zinc ...
X-ray absorption spectroscopy demonstrates that the atomic coordination of zinc and sulfur is different within eumelanised regions compared to pheomelanised regions. This not only impacts our fundamental understanding of pigmentation in extant organisms but also provides a significant contribution to the ...
After addition of 10 mL of a 6 N HCl solution sparged with N2, AVS was liberated as H2S, which was then stripped from solution during 40 min using N2 as a carrier gas, and collected in a trap containing 10 mL 5% zinc acetate (ZnAc), with a drop of antifoam. We expect that H2S ...
In solution, this zinc derivative exists as a trimer but crystallizes as a dimer 144 with two molecules of THF coordinated to each zinc center.183 In a similar way, the 1-mercuraindane 20 reacts with elemental magnesium to afford 1-magnesaindane 145, which is dimeric in THF at room ...
Moreover, powdered aluminum is unique in this respect inasmuch as other forms of elemental aluminum as well as other metals such as copper, zinc, cadmium, iron and the like produce unacceptable spurious polymerization problems. Moreover, only acrylic monomer systems comprising a urethane acrylate ...
Inorganic compounds of zinc and/or magnesium and/or calcium and/or boron may be added, also inorganic compounds of copper and/or manganese and/or selenium and/or molybdenum may be added to the liquid sulphur/urea melt. The inorganic compounds may be added in amounts of 1.0-2.5 weight %,...
(9 elements) while FTIR data contain 226 points between 1800 and 900 cm−1after interpolating the FTIR spectra to obtain one data point every 4 cm−1, each LA-ICP-MS data point has been quintupled. It makes correlation analysis more clearly readable and gives a significant weight ...
Zinc is also depleted in the vasculature of the leaf. Chromium is located mainly in the central vein, and in the prominent lesion, although the concentrations are relatively low [compared to Ni and Co]. Figure 4 Micro X-Ray Fluorescence (μXRF) image of a Glochidion cf. sericeum leaf ...
