Abstract: Metal recovery and separation systems and methods, and, more particularly, electrothermal chlorination (ETC) and electrothermal carbochlorination (ETCC) methods and systems for the selective metal extraction, such as extraction of critical metals from waste streams. Alternatively, other oxidants, such as fluorine, bromine, or iodine can be used in place of, or in addition to, chlorine. Further, alternatively, other reductants, such as metal(0) (like tin(0)) and H2, (including H2 in argon, such as between 1% and 5% H2 by volume in argon) can be used in place of, or in addition to, carbon. Embodiments of the present invention can utilize ETC in selective recovery of In from ITO-containing wastes and ETC coupled with ETCC for Ta recovery from capacitor waste.

Abstract: Provided herein are systems, devices, and methods for performing a medical procedure on a patient. The system includes a catheter device and a console for operating the catheter device. The catheter device includes a functional assembly that is located on the distal portion of the catheter and includes one or more electrodes. The console includes a diagnostic module for recording signals from the electrodes and a processing unit for processing the recorded signals.
