We report a facile and low-cost methodology for the simultaneous determination of codeine (COD) and its common co-formulated drugs acetaminophen (APAP) and caffeine (CAF) utilising cerium oxide nanopar- ticles modified screen-printed electrodes (CeO2-SPEs) for the first time. Interestingly, CeO2-SPEs offer a promising, sensitive, robust and chemically stable non-enzymatic electrochemical sensor for the simul- taneous determination of APAP, COD and CAF ... Read more

Herein, nanostructured metal oxides of essential soil nutrient elements (i. e. CuO and CaO) with definite shape and size were simply synthesized and their pesticidal activities against cotton leafworm (Spodoptera littoralis) were explored for the first time. These metal oxide nanostructures represented novel economic and eco:friendly nano:pesticides for sustainable plant protection and might boost the nutrient content of soil. The ... Read more

Recent advancements in electrode design are substantially linked to state-of-the-art nanomaterial fabrications. Herein, we report a simple one-pot hydrothermal synthesis of Cd(OH)2 with a platelet-like morphology, which was subsequently annealed at relatively high temperatures to produce a CdO/ Cd(OH)2 nanocomposite for the first time. It was found that the control of thermal treatment allowed tunable charge transport across the nanometre ... Read more

received high concern recent years. Thus, efficient removal of these organic pollutants and minimize their usage in environment are highly recommended. Herein, we report hydrothermal chemical modifications of commercial kaolin (CK) in presence of sodium hydroxide (alkaline-modified kaolin; AMK) and disodium hydrogen phosphate (phosphate-modified kaolin; PMK) reagents. Interestingly, these chemical modifications altered the physico-chemical characteristics of CK in term of ... Read more
