Hygiene measures were intensified when the COVID-19 pandemic began. Patient contacts were limited to a minimum. Visitors were either not allowed for a certain period or limited for the rest of the time. The hospital staff began to wear masks and gloves continuously. Clinical examinations and routine wound controls were also performed under intensif...

Two typical wastes (acidic wastewater and vanadium-bearing steel slag) produced in the metallurgical process of vanadium-titanium magnetite not only pose a huge threat to the environment, but also waste a lot of resources such as V, Ti, and Fe. In order to effectively treat the two wastes and recover the resources such as V, Ti, Fe and Ca, a collab...

A GPU-based, massively parallel coarse-grained CFD-DEM method was adapted to study the scale-up effect of residence time distribution of polydisperse particles in continuously operated multiple chamber fluidized beds, where the bed is scaled up either by keeping a constant length of each chamber and increasing the number of chambers (Scaling method...

A one-step electrodeposition approach to make a micro-nano superhydrophobic structure on the surface of copper was developed by using Choline chloride (ChCl)-based ionic liquid as the electrolyte. As compared with bare Cu, the contact angle of electrodeposited superhydrophobic coating reaches 157.8 degrees. The corrosion behavior of superhydrophobi...

Drag model is of critical importance for CFD simulation of flow characteristics in bubble columns. In this study, a novel drag model termed DBS-Local for the ratio of effective drag coefficient to bubble diameter is derived from the Dual-Bubble-Size (DBS) model based on Energy-Minimization Multi-Scale (EMMS). A thorough comparison demonstrates that...

The Hoganas method is considered the most effective method for producing reduced iron powder (RIP). How-ever, this method does not remove impurities; therefore, high-purity magnetite must be used as raw materials. In this study, when RIP was produced using magnetite concentrate (TFe = 64.86%), a strong raw material flexi-bility was observed. The in...
