The excellent gold extraction performance is accounted to the graphene areas and oxidized regions of rGO. The graphene areas spontaneously reduce gold ions to metallic gold, and the oxidized regions allow good dispersibility of the rGO material so that efficient adsorption and reduction of gold ions ...
In addition, the direct synthesis of core-shell like MOF@COF and the innovative deposition methodology used in this study offer a more efficient strategy in terms of time consuming compared to previous drop casting methods. Furthermore, the utilization of the DPV technique in this study provides ...

With over 200 gold and silver electrowinning cells installed worldwide, our systems are known for their high-current efficiency, safety, ease of sludge removal, and durability. It’s little wonder they have been trusted time and again to deliver cost-effective precious metals recovery. ...
second-order kinetic model. The best fitted models for MO and CR adsorption were the Langmuir isotherm and the Dubinin–Radushkevich, respectively. In addition, a possible adsorption mechanism was proposed for both dyes. The findings showed that α-Mn2O3nanoparticles are very efficient adsorbents ...
The chemicals known as PFAS are considered a severe threat to human health. Among other things, they can cause liver damage, cancer, and hormonal disorders. Researchers at the Technical University ...
There is an urgent need for highly efficient sorbents capable of selectively removing 99TcO(4)- from concentrated alkaline nuclear wastes, which has long been a significant challenge. In this study, we present the design and synthesis of a highperformance adsorbent, CPN-3 (CPN denotes cationic ...
This suggested that cleavage by the Cas9-sgRNA complex was less efficient at the pfpalm gene than at the pfcsp gene. Because the sgRNA for pfpalm was controlled under the PbU6 promoter, its transcriptional activity in P. falciparum might be weaker than that of the PfU6 promoter. This ...
