Semiconductor-based photoelectrochemical (PEC) organic transformations usually show radical characteristics, in which the reaction selectivity is often difficult to precisely control due to the nonselectivity of radicals. Accordingly, several simple organic reactions (e.g.

Article Synopsis
  • Chloride measurement is essential for determining the anion gap, yet bicarbonate can interfere with these measurements, leading to inaccuracies depending on the type of electrode used.
  • Different electrodes showed varying levels of non-selectivity towards bicarbonate, with some becoming more biased over time while others gained selectivity.
  • Adjusting calibrator bicarbonate concentrations significantly improved measurement accuracy, highlighting the need for laboratories to recognize and manage bicarbonate's impact on chloride assessments.

Non-enzymatic saccharide sensors are of great interest in diagnostics, but their non-selectivity limits their practical diagnostic abilities. In this study, we investigated the electrochemical oxidation of monosaccharides at nanoporous gold (NPG) catalysts with different contributions of surface crystallographic orientations. Fructose elicited no clear electrochemical response, but glucose, galactose, and mannose produced clear oxidative current.

The frequent detection of propranolol, a widely used β-blocker, in wastewater effluents and surface waters has raised serious concern, due to its adverse effects on organisms. UV/hydrogen peroxide (UV/HO) and UV/persulfate (UV/PDS) processes are efficient in eliminating propranolol in various waters, but the formation of oxidation products in these processes, as well as the assessment of their toxicity, has not been systematically addressed. In this study, we identified and compared transformation products of propranolol produced by hydroxyl radical (OH) and sulfate radical (SO).
