Water temperature was controlled at 28 ± 0.5 °C by using a water heating/cooling unit (AB Aqua Medic, Gewerbepark, Germany). The water quality parameters (pH, ammonia, nitrate, nitrite, dissolved oxygen) were assessed weekly. Fish received feed (D-4 Alterna Basic 2P, Skretting, Spain) ...

The presence of Co improves hot electrons’ lifetime due to some charge stabilisation. Still, the cobalt centre is the same since this would lead to the disappearance of the ‘free carrier’ infrared absorption behaviour, which only happens for at least 1 ns. The TIRAS observation is also ...
However, this nanoparticle-salt interaction can also be found in chemical applications in which nanoparticles have proved suitable to be used as an adsorbent for nitrate removal given their high specific surface, reactivity and ionic exchange capacity. In this work, the ionic exchange capacity ...
“Ensure access to water for all”, states Goal 6 of the UN’s Sustainable Development Goals. This worldwide challenge requires identifying the best water disinfection method for each scenario. Traditional methods have limitations, which include low effe
These slow heating rates (up to 4 °C/min) were adopted so as to observe the various thermodynamic reaction processes clearly15. When conducting DSC experiments, the sample masses can affect the calorimetry results49: if the sample mass is too high and the heating rate is too fast, self...
Formation of cracks in the alumina layer, which is of great importance in the deterioration of alumina layer and failure of the insulator and can lead to short circuiting between the conductive substrate and the heating element, can be observed in Fig. 18. Based on the results obtained from ...
Exposures to PM2.5 and five of its major components, including black carbon (BC), organic matter (OM), inorganic nitrate (NO3−), sulfate (SO42−), and soil particles (SOIL), were estimated using satellite-based spatiotemporal models. The associations between long-term exposures to PM2.5...
Heat storage enables the optimization of the sizing of installations in heating networks, particularly with respect to the extension of existing networks. The main elements of a thermal energy storage system are displayed in Figure 6. Figure 6. The main elements of a thermal energy storage system...
heating to produce soluble complex compounds with the compositions Pb(HSO4)2and H2[PbCl4]. Nitric, acetic, and certain organic acids (for example, citric) dissolve lead with the formation of Pb(II) salts. Lead salts are classified according to water solubility as soluble (acetate, nitrate, ...
