Title: Analysis of Swap-in-Capillary Electrospray Ionization in Drugs and Biofluids
Abstract: An issue that has started to be tackled is pretreatment of samples when they are in bio fluids (e.g. blood), before they can be analyzed in an ESI-MS. Spray-in-capillary electrospray ionization (SC-ESI) is a variant of liquid ionization that can simultaneously extract sample analytes and deliver them through a capillary for ionization and subsequent detection using mass spectrometry. While traditional approaches can be used to extract drugs from bodily fluids, the capacity to directly analyze fluids has considerable benefits. The SC-ESI setup is well-suited to address the challenges of rapid and efficient sample extraction. While its use can extend to bodily fluids, the use of swabs as a sampling mechanism can also extend to the evaluation of drugs in capsule and pill forms. This literature review will present the pertinent details of SC-ESI, its ability to detect drugs from blood and saliva and highlight potential future uses. With a disposable swab that is connected to a holder, no pretreatment of the sample is required which allows for increased data collection rates and increased confidence when considering its capacity to rapidly capture multiple replicates.

Title: Effects of the Lorentz Force in Electrochemical Systems
Abstract: Advances in electrochemistry depend on a better fundamental understanding of complex reactions at the electrode/electrolyte interface. A promising direction is to investigate reactions at the atomic scale, which could lead to new insights into catalytic processes and enhanced performance. Magneto-electrochemistry has recently become an attractive fundamental topic for manipulating and improving electrocatalytic performance and offers many strategic advantages in controlling and understanding electrochemical reactions that prove difficult to regulate in conventional electrochemical experiments. Magneto-electrochemistry is a cross-disciplinary approach involving electrochemistry and magnetism often leading to unexpected experimental outcomes. However, a focused investigation into magneto-electrochemistry can lead to unexpected insights into fundamental electrochemical processes, and technological breakthroughs, providing significant opportunities for advancing the broad application of electrochemistry. There are reports of using the Lorentz force towards improved mass transport, uniform morphology of electrodeposits, electrode kinetics, and enhanced electrocatalytic performance. This literature review provides insights on some effects of the Lorentz force in electrochemistry with some recent applications.
