ZnO nanoparticles (ZnO-NPs) were successfully fabricated by soft chemical technique from zinc acetate di-hydrate (Zn(CH3COO)(2)center dot 2H(2)O) and octadecylamine (CH3 (CH2)(17)NH2). The crystallinity of the grown product was analyzed by the XRD technique revealing the as-prepared nanoparticles (NPs) have hexagonal wurzite structure. Their morphology was investigated by FE-SEM and TEM, which showed that well dispersed spherical particles of 10 +/- 4 nm in diameter had been formed. The optical property of ZnO-NPs was confirmed by the photoluminescence spectroscopy showing an intense room temperature photoluminescence in the violet region of 382 nm. Furthermore, the synthesized ZnO-NPs showed a better photo-catalytic activity than that of commercial Degussa P-25 powder during photochemical degradation of methyl orange (MO) dye. Also, the Zn-2p1/2, Zn-2p3/2, and O-1s peaks in XPS clearly suggest that the grown nanoparticles are ZnO. Additionally, liquid chromatography mass spectroscopy (LC-MS) was applied to observe the degradated compounds from photo-catalytic degradation of methyl orange (MO) dye in presence of ZnO-NPs.

Homogenous Sono-Fenton reaction can trigger long term bactericidal effect against Acinetobacter baumannii due to residual stress induced by reactive oxygen species

Pranjal, Soujanya Ghosh, A. P. Habeeb Rahman, Sankha Chakrabortty, Shirsendu Banerjee, Ramesh Kumar, Amrita Mishra, Byong-Hun Jeon, Cecilia Stalsby Lundborg, Suraj K. Tripathy

Summary: A systematic study was conducted to understand the bactericidal mechanism of ultrasound assisted Fenton reaction (Sono-Fenton) against multidrug resistant Acinetobacter baumannii. The study found that SF achieved approximately 99% inactivation efficiency against A. baumannii within 90 minutes under weak acidic conditions. The combination of ultrasound and H2O2 was found to be more efficient, and the generation of multiple reactive oxygen species (ROS) may have led to the membrane damage of the bacteria.

Prediction of phosphate adsorption amount, capacity and kinetics via machine learning: A generally physical-based process and proposed strategy of using descriptive text messages to enrich datasets

Baiqin Zhou, Huiping Li, Ziyu Wang, Hui Huang, Yujun Wang, Ruichun Yang, Ranran Huo, Xiaoyan Xu, Ting Zhou, Xiaochen Dong

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
