Recovery of Metals from Electronic Waste-Printed Circuit Boards by Ionic Liquids, DESs and Organophosphorous-Based Acid Extraction.

The extraction of metals from waste printed circuit boards (WPCBs) with ionic liquids (ILs), Deep Eutectic Solvents (DESs) and organophosphorous-based acid (Cyanex 272) has been presented. The study was undertaken to assess the effectiveness of the application of the new leaching liquids, and the new method of extraction of metals from the leachate and the solid phase with or without the leaching process. Solvent extraction from the liquid leachate phase has been studied in detail with popular ILs, such as tetraoctylphosphonium bromide, {[P][Br] and tributyltetradecylphosphonium chloride, [P][Cl] using Aqueous Biphasic Systems (ABS) method.

Ectopic bone formation by gel-derived bioactive glass-poly-L-lactide-co-glycolide composites in a rabbit muscle model.

In this study we aimed to assess the in vivo osteoinductive properties of two composite scaffolds made of PLGA (poly-L-lactide-co-glycolide) and two types of gel-derived bioactive glasses, namely a high silica S2 bioactive glass (S2-PLGA composites) or high lime A2 bioactive glass (A2-PLGA composites). To achieve that, the potential of the composites to induce ectopic bone formation in a rabbit muscle has been examined along with the control PLGA scaffold. Cylinder-like scaffolds of 7  ×  3 mm (width  ×  height) were implanted into pouches created in the latissimus dorsi muscle of 18 New Zealand rabbits.

Fatty acids composition in erythrocyte membranes of athletes after one and after a series of whole body cryostimulation sessions.

SYNTHESIS AND ANTIMICROBIAL PROPERTIES OF NEW MANDELATE IONIC LIQUIDS.

Novel mandelate ionic liquids with quartenary ammonium cations were synthesized and characterized. The compounds exhibit antimicrobial activity and the most potent one is of similar efficacy against Gram+ bacteria as its counterpart chloride. On the other hand, the mandelates are much less active against Gram-bacteria and fungi.

Rheological properties of erythrocytes in patients infected with Clostridium difficile.

Methodology of selecting the reference source for an active noise control system in a car.

At the end of the 20th century, a significant development in digital technologies of signal processing made it possible to apply active noise control methods in new domains. A proper selection of the reference signal source is a main problem in implementing such systems. This paper presents an estimation method based on an indicator of the coherent power level.
