Adsorption of lead(II) from aqueous solution using Africa elemi seed, mucuna shell and oyster shell as adsorbents and optimization using Box–Behnken design

“…Various methods for the removal of these heavy metals from industrial wastewater have been developed such as electrochemical treatment (Kobya et al 2016), coagulation/flocculation (Luo et al 2017;Gaikar et al 2016;Sen et al 2017), adsorption (Berber-Villamar et al 2018;Wang et al 2016a, b), ion exchange processes (Yang et al 2015;Ansari et al 2017), solvent extraction (Lam et al 2018) and membrane filtration (Samadder et al 2017;Aravind et al 2018). Among all the stated techniques, adsorption process appears to be the alternative method due to its excellent removal capacity, convenience, economic cost and simplicity (Lalchhingpuii et al 2017;Okoye et al 2018;Lu et al 2018;Lowe et al 2015).…”

Conversion of single crystals of a nickel(II) dithiocarbamate complex to nickel sulfide crystals

“…Techniques utilizing separate reactants have been applied to the synthesis of NixSy compounds, with varying degrees of success. Synthetic methods include solvo-and hydrothermal, [20,[41][42][43][44][45][46] solidstate, [47][48][49] microwave-assisted, [11,17] spray pyrolysis [50,51] and solution-based [52] techniques. In these cases, the phase and morphology of the resultant NixSy material is adjusted by varying the solvent, capping ligand, precursors, reaction temperature and time.…”

3D nanorhombus nickel nitride as stable and cost-effective counter electrodes for dye-sensitized solar cells and supercapacitor applications

“…Hence the observed peak shis mainly occur at a lower resistance, showing the pseudo-capacitive characteristic of the Ni 3 N electrode. 40,41 All of the CV curves show a similar response even when the scan rate is increased to 500 mV s À1 , this could be caused by fast ion and charge mobility in the KOH electrolyte. The areal capacitance of the Ni 3 N electrode was derived from the integral area under the curve of the obtained CV curves using the following equation (eqn (1)); 41 Areal capacitanceðCÞ ¼…”
