The characteristic mass which gave an integrated absorbance of 0.0044 s was found to be 46 pg. An absolute detection limit (3s) of 36 pg was obtained. The method was applied successfully in the determination of germanium in coal fly ash, soil and river sediments following the decomposition of...
I[nNa2 simplified model where the HER is the only competing reac- tion of the NRR and the mass and electron transfer are not rate-determining factors, the Faradaic efficiency (FE) for the NRR can be estimated by the Boltzmann distribution [63, 83]: fNRR = 1/[1 + exp(−...
The temperatures of single-bubble sonoluminescence We observe extraordinarily intense single‐bubble sonoluminescence (SBSL) from concentrated sulfuric acid (H2SO4) containing noble gases. Strong atomic Ar ... KS Suslick,DJ Flannigan - 《Journal of the Acoustical Society of America》 被引量: 0发表:...
Spatially dependent changes in the atomic emission and atomic fluorescence intensities in an argon inductively coupled plasma (ICP) as a function of the aerosol transport rate (mass of aqueous aerosol introduced per unit time) have been observed. The ion emission intensity per mass of analyte introd...
Briefly, it consists on the reaction of graphite flakes with concentrated H2SO4 and KMnO4 in order to obtain individual sheets in an oxidized state. The resultant suspension was extensively washed with distilled water by filtration and centrifugation and finally subjected to dialyses to remove ionic...

The present work describes the total Se determina-tion in urine samples by focused microwave-assisted digestion and,nal detection by HG-AFS.Complete digestion of the sample is obtained by using the mix-ture HNO3–H2SO4.The reduction of Se(VI) to Se(IV)has been performed in a sand-bath ...
pristine MS and alloyed MSSE structures were analysed by aberration-corrected scanning transmission electron microscopy (ac-STEM) using HAADF imaging (also known as Z-contrast mode), where the intensity of the HAADF signal is proportional to the total mass of the atoms in a given column [51,52...
