Noninvasive Glucose Detection with Biodegradable Electrodes from Rice Starch Functionalized with a Carbon Quantum Dot/Nickel Oxide Nanocomposite

Analysis &Sensing, EarlyView.
The graphical abstract shows an eco‐friendly approach to fabricating a biodegradable electrochemical sensor. Carbon quantum dot/nickel oxide (CQD/NiO) nanocomposites are synthesized using Aloe arborescens leaf extract, which served as a natural reducing and stabilizing agent.

Deep oxidation of NO via catalytic ozonation

Journal of the Air & Waste Management Association
In addition to selective catalytic reduction (SCR) and selective non-catalytic reduction (SNCR) which are available to remove NOx from flue gas, oxidation method is receiving more and more attention because this method makes it possible to remove NOx and SO2 from flue gas simultaneously by wet scrubbing.

Catalytic ozonation of 2-dichlorophenol by metallic ions

Water Science and Technology, 2003
This research is mainly to explore functional improvement by adding various kinds of metallic ions in the ozonation of 2-chlorophenol solution. During the experiment, various kinds of metallic ions (Pb+, Cu2+, Zn2+, Fe2+, Ti2+, and Mn2+) were added; it was found that the reaction rate increased in all cases.

Synergism and Radicals Dynamics in the Efficient Degradation of Basic Blue 41 via UV/Chlorine Process: Dependence on Processing Conditions

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The UV/chlorine process, a promising advanced oxidation process, demonstrates remarkable synergism and radical dynamics for the efficient degradation of Basic Blue 41 (BB41). This study investigates the effects of processing conditions, including solution temperature (25°C–45°C), pollutant dose (10–40 mg/L), chlorine concentration (100–1000 μM)
