TL;DR: In the detailed literature survey, value distributions for different electronic waste samples were calculated, and it was showed that the major economic driver for recycling of electronic waste is from the recovery of precious metals.

TL;DR: A review of the current state-of-the-art in the evaluation of steel cleanliness can be found in this paper, where a wide range of important operating conditions throughout the steelmaking and casting processes are discussed.

TL;DR: In this article, a review of gas-liquid two-phase flow in minichannels or microchannels related to PEM fuel cell applications is presented, where the authors focus on water management in fuel cells.

TL;DR: In this article, a review of recent developments in modeling phenomena related to fluid flow in the continuous casting mold region, and the resulting implications for improving the process is presented, including the transport of bubbles and inclusion particles, multi-phase flow phenomena, the effect of electromagnetic forces, heat transfer, interfacial phenomena and interactions between the steel surface and the slag layers.

TL;DR: In this paper, the authors extensively review published research on inclusions in ingot steel and defects on ingot products, methods to measure and detect inclusions, the causes of exogenous inclusions and the transport and entrapment of inclusions during fluid flow, segregation, and solidification of steel cast in molds.
