The separation of graphites and cathode materials from spent lithium-ion batteries (LIBs) is essential to close the loop material used in LIBs. In this study, roasting characteristics LIB are carefully analyzed, effects on surface morphology elemental chemical states electrode fully investigated by thermogravimetric analysis, SEM-EDS, XPS explore roasting–flotation enhancement mechanism. Then, ...

It is possible to obtain good performance from a flotation plant but it has proved difficult to maintain such performance. Recovery rates on a flotation plant can be around 90% and often lower, making flotation one of the least efficient processes in the concentration path. Hence, over the last few decades much research and development has gone into the stabilization and optimization of flotati...

Auditory neurons preserve exquisite temporal information about sound features, but we do not know how the brain uses this information to process the rapidly changing sounds of the natural world. Simple arguments for effective use of temporal information led us to consider the reassignment class of time-frequency representations as a model of auditory processing. Reassigned time-frequency repres...

Porous silica-based microspheres encapsulating aqueous glycerol can be potential curing agents for one-component foams (OCFs). Such agents have the advantage of an enhanced sustainability profile on top of being environmentally friendly materials. A synthetically convenient and scalable sol-gel process was used to make silica and organosilica microspheres doped with aqueous glycerol. These meth...

We report a very rare case of acute pulmonary edema caused by hypoglycemia from insulin overdose during an attempted suicide. A 16-year-old woman with type 1 diabetes was brought to our hospital because of hypoglycemic coma. She exhibited severe hypoxia; upon intubation, bloody froth poured out of the tube. Chest X-ray revealed bilateral infiltrates. Endocrinological data revealed high concentr...

of blood-stained froth came out through the wound, very close to the line of fracture. There was a moderate amount of haemoptysis just after the occurrence of the injury. Evidently the lung was wounded at the point where it was caught between fragments of the broken rib and through which air excaped, leaving the prolapsed portion with 110 chance ,of being inflated. Under the circumstances I tho...

A flotation bank is a serial arrangement of cells. How to optimally operate a bank remains a challenge. This article reviews three reported strategies: air profiling, mass-pull (froth velocity) profiling and Peak Air Recovery (PAR) profiling. These are all ways of manipulating the recovery profile down a bank, which may be the property being exploited. Mathematical analysis has shown that a fla...
