Photocatalytic water splitting for hydrogen evolution is one of the most promising methods to mitigate environmental and energy-related issues. In this study, manganese cadmium sulfide (Mn x Cd 1-x S) solid solution is used to construct a p–n heterostructure with NiCo 2 O 4 through a hydrothermal method.

Abstract. The divalent cations of cobalt, zinc, and nickel are essential nutrients for bacteria, required as trace elements at nanomolar concentrations. However, at micro- or millimolar concentrations, Co 2+, Zn 2+, and Ni 2+ (and "bad ions" without nutritional roles such as Cd 2+) are toxic. These cations are transported into the cell by ...

The nickel–cadmium battery system still uses the same positive electrode as the nickel–iron one, while the negative electrode is cadmium. The maximum cell voltage during charge is 1.3 V, and the average cell voltage is 1.2 V. In eqns [4]– [6], the cell reactions during charging and discharging are presented. At the cathode electrode,

In contrast to cadmium, copper, zinc, and nickel, cobalt showed a clear increase in the surface water. The profile in Fig. 6b shows a representative picture of the cobalt distri- bution. In the surface water down to 500 m the average con- centration found is 33 pM and for the deep water (>500 m), 26 pM for all stations.

Heavy metals such as lead (Pb), nickel (Ni), chromium (Cr), cobalt (Co), copper (Cu), and cadmium (Cd) are exported at greater levels. Untreated wastes generated as a result of production processes have detrimental causes on the environment (Gavrilescu 2004 ; Chandra and Kumar 2017a ; Kumar et al. 2021a ).

The objective of this research is to investigate a novel hydrometallurgical route to recover cadmium, cobalt and nickel from hydrochloric acid leachates of spent …

Abstract. Activated sludge processes are often inhibited by nickel, cadmium, and cobalt. The inhibitory effect of these heavy metals on a synthetic wastewater treatment process was tested through pulse microrespirometry; i.e., pulse of substrate injected in a microreactor system. The inhibitory effect was tested under different conditions ...

Nickel-cadmium (Ni-Cd) batteries have high power and energy density, high efficiency of charge/discharge, and a low cycle life ( Table 2 ). The primary demerit of Ni-Cd batteries is a relatively high cost because the manufacturing process is expensive. In contrast, Cadmium is a toxic-heavy metal, hence posing issues associated with the disposal ...

Rhizopus stolonifer and Cunninghamella blakesleeana trained after five passages to tolerate elevated concentrations of copper simultaneously acquired a tolerance to elevated levels of cadmium, cobalt, nickel, and lead. The acquired tolerance to copper was not stable in the absence of the metal, as serial transfers to a copper-free medium …

copper (Cu), nickel (Ni), cobalt (Co), cadmium (Cd), and manganese (Mn), among others, have garnered attention for their biological utilization by phytoplankton and have been studied to determine the influence they exert on primary production in the oceans (Sunda 1989; Bruland et al. 1991; Morel and Price 2003; Twining and Baines 2013).
