For each ton of steel produced from a typical steelmaking plant, up to several tens of kilograms of dust, containing significant amounts of valuable and/or environmentally harmful metals, are also produced. A hydrometallurgical ...

Continuous simulated moving bed (SMB) type ion exchange processes are usually operated in cross-current mode for metal separations whereas counter-current mode is commonly used for fine chemicals. The use of both process ...

Prevailing theories in biological pattern formation, such as in morphogenesis or multicellular structures development, have been based on purely chemical processes, with the Turing models as the prime example. Recent studies ...

Family business groups are highly complex ownership structures. In this chapter, we suggest that owning a family business group needs to create benefits that overcome the transaction costs and ownership costs emerging from ...

Electrodialysis (ED) is a promising emerging electrochemical membrane technology for nutrient concentration and recovery from wastewater. However associated environmental safety aspects have to be assessed before utilizing ...

The Internet of Things (IoT), a type of cyber-physical system, has led to a drastic growth in the number of devices and sensors connected to each other and to the digital word. This has further led to an exponential increase ...

Arsenic-contaminated sulfuric acid solutions are produced in large quantities as by-product during pyrometallurgical processing of sulfide minerals. Options for re-using such acid solutions are increased if the arsenic is ...

We draw insights from the perspective of theory of complex adaptive systems to gain knowledge about complex interactions and the dynamic nature of entrepreneurial family business groups. We develop a theoretical understanding ...

Herein, to meet the requirement of the stringent sulfur emission and discharge rate standards based on World Health Organization (WHO) and Environmental Protection Agency (EPA), polyamide/titanium dioxide (PA/TiO2) thin ...

In this research, the separation of Li, Ni, and Co by solvent extraction was studied from synthetic Li-ion battery waste leachate. The purpose was to propose a process for producing all the metals with over 99.5% purities, ...
