Prior to the mechanical processing, discharging is necessary to prevent hazards. While the discharging process, different phenomena can occur changing the characteristics of the functional units of LIB. This study reveals the influence on the mechanical recycling and the obtained material when different discharge levels are used for various cells differing in their cell chemistry. It shows that for different cells, for example, copper deposits happen on the cathode as well as active material deposits on the separator foil. These new properties deteriorate the black mass quality and show contamination of the products with other material streams. It is being tested whether established sub-processes are suitable. However, it becomes clear that further recycling steps (e.g. flotation, hydrometallurgy) can be influenced as well as their product quality and element specific yield.

Background: As a common postoperative neurological complication, postoperative delirium (POD) can lead to poor postoperative recovery in patients, prolonged hospitalization, and even increased mortality. However, POD's mechanism remains undefined and there are no reliable molecular markers of POD to date. The present work examined the associations of cerebrospinal fluid (CSF) sTREM2 with CSF POD biomarkers, and investigated whether the effects of CSF sTREM2 on POD were modulated by the core pathological indexes of POD (Aβ42, tau, and ptau).

The demand for rapid, field-deployable detection of hazardous substances has intensified the search for plasmonic sensors with both high sensitivity and fabrication simplicity. Conventional approaches to plasmonic substrates, however, often rely on lithographic precision or complex chemistries limiting scalability and reproducibility. Here, a facile, one-step synthesis of vertically aligned 2D nanosheets composed of intergrown CuO/CuO crystallites is presented, fabricated via oxygen plasma discharge on copper substrates.

Background: Tacrolimus is a commonly used immunosuppressant with well-defined side effects, including hypertriglyceridemia and hyperglycaemia. However, acute pancreatitis is still not widely recognized as an adverse event related to tacrolimus.
Case Presentation: A 60-year-old male was admitted to the intensive care unit with symptoms and signs of acute pancreatitis.
