ZnO nanofluids – A potential antibacterial agent
Open accessAbstract
In this work, ZnO nanofluids were produced by a medium mill with a pH value of about 7.2 and characterized by Nano-Sizer and SEM. After milling, ZnO nanofluids were formed with an average particle size of ∼198.4 nm. The ZnO nanofluids used for testing were stored for different periods (1-, 90- and 120-day) and kept in different conditions (under the light and in the dark). The antibacterial activities of these ZnO nanofluids were evaluated by estimating the reduction ratio of the bacteria treated with ZnO. The results showed that the ZnO nanofluid stored for 120 days under the light had the best antibacterial behavior against Escherichia coli DH5α. SEM images suggest that an interaction between the ZnO particles and the E. coli bacteria cells caused by electrostatic forces might be a mechanism.

Photocatalytic materials are currently utilized to convert solar energy into chemical energy by oxidization or reduction of materials to get useful components such as hydrogen.
“Photocatalytic materials are currently being utilized in order to convert solar energy into chemical energy by oxidization or reduction of materials to get useful components such as hydrogen.”
From Renewable energy harvesting with the application of nanotechnology: A review (2019) · cites this paper as [50]
The Introduction discusses photocatalytic activity, and §3.2 (Antibacterial tests) describes light-promoted reactions that produce oxidizing species harmful to bacteria. Neither passage addresses converting solar energy into chemical energy or producing hydrogen; searches for those terms found no supporting passage in our copy. (LLM, conf=0.74)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
