Summary: In this study, the extract of acanthopanax senticosus leaf (ASLE) prepared using a one-step pure water extraction method is used as a sustainable eco-friendly corrosion inhibitor for carbon steel in acidic solutions. The corrosion inhibition efficiency is evaluated by weight loss method and electrochemical tests, and the compositions and microstructures of ASLE and corrosion products are analyzed. The results show that ASLE is an efficient mixed-type corrosion inhibitor for carbon steel in 1 mol/L HCl, with a maximum corrosion inhibition efficiency of 98.79% after 144 h immersion with the addition of 150 mg/L. It also displays superior long-term corrosion inhibition performance.

Summary: This study evaluated the inhibition performance of Randia monantha pulp and seed extract on the corrosion of A36 mild steel in 1M HCl solution. The results showed that the extract had a good inhibition effect, achieving an inhibition efficiency of 91% at a concentration of 1000 ppm. Electrochemical measurements indicated that the molecules of the extract acted as a mixed-type inhibitor and their adsorption process obeyed the Langmuir isotherm primarily through a physisorption mechanism. Surface analysis confirmed the adsorption of compounds from the extract, and chemical quantum calculations provided insights into the electronic properties and interactions between the inhibitor and metal surface.

Summary: This study aimed to establish a protocol for in vitro multiplication of kiwano plants using meta-topolin, silver nanoparticles, and LED treatments. The results showed that silver nanoparticles did not show a positive effect on shoot growth but may have improved rooting of Cucumis metuliferus explants. Red:blue light and white light had similar effects on explant growth, while the absence of red or blue lights caused abnormalities in plantlets. Meta-topolin was identified as a suitable cytokinin for in vitro growth of Cucumis metuliferus cultures.

Summary: In this study, nitrogen-doped carbon dots (NDCDs) were developed as a drug carrier for anti-cancer drug delivery using quercetin (QC) as a model drug. The NDCDs were prepared using a simple hydrothermal method and exhibited small particle size and enhanced fluorescence properties. The NDCDs-QC conjugate showed nontoxicity to colon cancer cells and demonstrated the ability to kill cancer cells in the NDCDs-QC form. This development holds promise for drug delivery and bio-imaging in cancer therapy.
