Zeolite, as received, was in the Na form, was ion exchanged to the NH4+ form using an aqueous solution of NH4NO3 and was subsequently dried at 373 K for 24 h.
The IMS of Ag-NPs in Purolite C100E resin was carried by following the standard procedure which included the loading of the functional groups of the polymer in the initial Na form with Ag+ ions by using 0.1 M AgNO3 solution followed by their reduction with NaBH4 solution.
Shengli brown coal in different forms (H-form and Na form) has been gasified in fuidised-bed quartz reactor to examine the effect of AAEM (particularly Na) on the char yields at different temperatures.
These different types of HA and NA form the basis of the H and N distinctions in, for example, H5N1.
The Internet "is robbing slang of a lot of its sociolinguistic exclusionary power," said Robert A. Leonard, a linguistics professor at Hofstra in Hempstead, N.Y., whose slang credentials include being a founding member of the doo-wop group Sha Na Na, formed in the late 1960s.
The technique of diffusion gradients in thin films (DGT) is designed to measure in situ labile trace metals; in a DGT device, the metal species are trapped in a resin gel comprising a Chelex resin in its Na-form after their diffusion across a diffusion layer comprising a polyacrylamide hydrogel.
Metastable pits (appeared here as oscillations in current in the nA range) form at potentials close to the pitting potential (Epit).
The *čan 1 etymon is found throughout Burmic, also in a nasal-prefixed form in Na languages and in many Qiangic languages.
With the two-stage reactor configuration, the AAEM-free volatiles generated from the pyrolysis of the H-form coal in the fluidised bed came into direct contact with the char from NaCl-loaded or Na-form coals in the fixed bed.
The different volatilizing extents of Na for different coal samples 5H-form coal, 0.02H-form coal, raw coal and Na-form coal) demonsamples 5H-forme remaining Na in coal after acid wash was in fairly stable forms.
