Calibrated Inductively coupled plasma optical emission spectrometry (ICP-OES; Perkin Elmer, Optima 4100DV, Germany) was used [19] to analyze the concentration of heavy metals in the muscle tissue and water samples after they had been treated with nitric acid (Merck, Darmstadt, Germany) and filter...
In this work, the electronic properties of gallium nitride nanosheets (GaNNSs) as a semiconductor can be tuned by transition metals (TM = Ti, Cr, Fe, Ni and Zn) doping for adsorbing of nitric oxide molecule at Grimme-corrected PBE/double numerical plus polarization (DNP) level of theory. ...
About 5-10 mg of sediment samples were weighed in tin containers and introduced into the combustion reactor through the Thermo Scientific™ MAS Plus Autosampler with oxygen. For TC and TN determination, after combustion, the resultant gases were conveyed by a helium flow to a layer packed with...
Following the sample drying process, a 1 g sample was digested using nitric acid and perchloric acid, as described by Mupambwa and Mnkeni [11]. The digested samples were analyzed for selected heavy metals using a calibrated Atomic Absorption Spectrophotometer (PinAAcle 900F, PerkinElmer Inc., ...
Prior to ultrasonication, 62.5 µL of a TEMPO solution (25 mM) is dissolved into 10 ml DI water to which 10 mg catalyst is added. The signal of TEMPO is then measured at given time intervals during ultrasonication on a Bruker EMXplus-9.5/12. The measurements were conducted in...
Finally, the acid digests were brought up to 5 ml with ultrapure water. The final concentrations of each element studied were expressed as mg gÀ1 of dry material weight. Reagents. De-ionized water with a resistivity of X18 MO cmÀ1 obtained using a MilliQPLUS 185 system, Millipore (...
Aqua regia is a mixture of two strong acids—nitric acid and hydrochloric acid. He found that most of the platinum metal dissolved, leaving a small amount of black powder. Other chemists had not bothered to study the powder. But Tennant did. He discovered that it had properties very ...
The interactive treatment, which induced TSW or ADW at 25 or 50% plus 50 mM Glycine betaine (GB) produced significantly greater amount of the aforementioned leaf photosynthetic pigments. Elemental status of the Kapok seedlings Irrigation with TSW and ADW at 100% significantly decreased the ...
Moreover, the lowest cell viability occurred in PCP-Mn-DTA@GOx@1-MT plus glucose after 48 h post-incubation. The results indicated that the nanosystem effectively killed the tumor cells through GOx-catalyzed ROS generation (Fig. 4d, e), and the addition of glucose further promoted the ...
