PtCo, and PtNi IMCs nanoparticles on the whole carbon black supports with narrow particle size distributions (Fig.3a–c). The statistical analyses of particle size based on the HAADF-STEM images were consistent well with the XRD results. Moreover, elemental mapping with energy-dispersive X-ray ...
This underes- timation can be seen from Fig. 2 by comparing the magnetic moment of a collinear from a calculation where the spin-orbit coupling is neglected (green squares) with tchluesmteorm(ee.gn.tTs obb3,tTaibn5eadnfdroTmb6a) calculation which includes spin-orbit coupling (red open...
The differential-pressure variation (lower-surface pressure minus upper-surface pressure) along a body of revolution a t small angle of attack is obtained from the second- o r d e r shock-expansion method of reference 6 by evaluating the variation of the slope of the elemental normal-force ...
These U. rotundata mats interpose a barner for oxygen diffusion between the sediment and water or air and may have a local impact on biogeochemical P and N fluxes. The aim of the present study was to descnbe the sea- sonal vanation of phosphate, ammonium and oxygen fluxes between the ...

It is important in determining the elemental composition of a molecule and in gaining partial structural insights using mass spectral fragmentations. GC-MS based metabolomics can comprehensively resolve more than 300 compounds, but is limited to the analysis of compounds typically less than <500 Da....
Sediment samples were sieved and the fraction of particle sizes <63 µm were analyzed for total Hg (EPA Method 7473) [43] as well as organic carbon and total nitrogen using an elemental analyzer (EPA Method 440.0) (Costech, Valencia, CA, USA) [43,44]. Samples were weighed before and...
The Hg exposure of miners has been tested in various studies using urine (elemental Hg), hair (methylmercury), and blood (organic Hg). The significant difference in the Hg levels of the three sample groups indicates that human scalp hair can be used as an alternative biological indicator in ...

Xcalibur software was used for instrument control and calculation of mass errors and elemental compositions. The identity of target metabolites eluting at slightly different retention times in the mucus samples relative to the reference standard solutions or those that showed nearby eluting compounds with...
