Raschman, Leaching of stibnite by mixed Na2S
and NaOH solutions, Acta Technica Corviniensis, Bull.
The researchers mixed tea leaf extract with cadmium sulphate (CdSO4) and sodium sulphide (Na2S
) and allowed the solution to incubate, a process which causes quantum dots to form.
Buffer solution modulation: Buffer solutions were prepared as described by Menke et al  to include a trace-element solution, a carbonic acid buffer solution, a phosphate buffer solution, a sodium sulfide reducing solution (Na2S
) and a resazurin indicator.
The electrode is then dipped into 0.1 M Na2S
methanol solution at room temperature for 30 sec, rinsed with methanol, and dried by heating in air.
After rinsing, 2 ml of sodium sulfide solution (0.32% Na2S
in 100 mM phosphate buffer pH 7.4) and a sulfide glutaraldehyde solution (0.16% Na2S
and 3% glutaraldehyde in 100 mM phosphate buffer pH 7.4) were bolus injected.
The association between lead contamination on the hand and blood lead concentration: a workplace application of the sodium sulphide (Na2S
The GO-AgNP sheets were crosslinked by PEG in the presence of Na2S
44, which was accomplished by adding 200 mg of PEG dissolved in 5 mL of water under continuous sonication for 10 min, followed by addition of 20 mg of Na2S
dissolved in 5 mL water.
Then, the detecting sensors were successively inserted in six kinds of different concentrations of Na2S
solution formulated by PBS buffer (5 [micro]L, 10 [micro]L, 20 [micro]L, 40 [micro]L, 80 [micro]L, and 160 [micro]L).
Preparation of Artificial Saliva: The artificial saliva used in this study was of the following composition: Sodium chloride (NaCl) 0.400 g; Potassium chloride (KCl) 0.400 g; Calcium chloride monohydrate (CaCl2H2O) 0.795 g; Sodium dihydrogen phosphate (NaH2PO4) 0.69 g; Disodium sulphide hydrate (Na2S
x 9H20) 0.005 g; Urea 1.0 g; Distilled water 1000 ml.
The application of Na2S
increases the phosphorylation of serine 1179 in eNOS to raise serum nitrite and nitrate levels and attenuates cardiac arrest-induced mitochondrial dysfunction.
.9H2O (0.5 g/l) generally added before inoculation.
