Summary: This study investigated the effects of different nanoparticles on lettuce grown in soil and found that the co-interactions of nanoparticles can affect their accumulation and distribution in plants. Additionally, the size of nanoparticles varied between roots and shoots, possibly as a result of the dissolution of nanoparticles in the rhizosphere or the formation of transformed nanoparticles.

Summary: This study investigates the combined use of cold argon plasma (CAP) and metal oxide nanoparticles for antibacterial treatment. The results demonstrate that the combination of CAP and redox-active metal oxide or metal fluoride nanoparticles effectively inhibits bacterial growth, damages DNA, and disrupts the cell wall. The combination of CAP and CeF3 nanoparticles shows the strongest antimicrobial effect on plasmid DNA, while the CAP and WO3 combination is most effective against bacterial genomic DNA. CeF3 nanoparticles exhibit strong antimicrobial and DNA-damaging properties for the first time.

Summary: An elegant method for synthesizing nanocomposites consisting of cerium-containing nanoparticles stabilized by carboxymethyl cellulose (CMC) macromolecules at room temperature was introduced in this study. The nanocomposites were characterized using microscopy, XRD, and IR spectroscopy analysis. The crystal structure of the inorganic nanoparticles, corresponding to CeO2, was determined and a mechanism for nanoparticle formation was proposed. The study demonstrated that the size and shape of the nanoparticles in the resulting nanocomposites were independent of the ratio of the initial reagents. Spherical particles with a mean diameter of 2-3 nm were obtained in different reaction mixtures with a cerium mass fraction ranging from 6.4% to 14.1%. The study also proposed a dual stabilization scheme for CeO2 nanoparticles involving carboxylate and hydroxyl groups of CMC. These findings suggest that the easily reproducible technique has promise for the large-scale development of nanoceria-containing materials.

Summary: This study found that engineered ZnO nanoparticles (NPs) exist in particle and ion states in aqueous solutions, and the phytotoxicity of ionizable metal oxide NP dispersions negatively affects root elongation. Exposure to ZnO NPs leads to accumulation of zinc in roots, inhibition of chlorophyll synthesis, and abnormal cell wall metabolism, which ultimately result in root elongation stagnation and plant death.

Summary: To survive in low oxygen water, water spiders collect and replenish air into their diving bell. Inspired by this strategy, researchers have developed a nanofiber coating that displays excellent and sustainable scalephobic capability underwater. This coating inhibits scale nucleation and reduces scale adhesion, resulting in a 98% reduction in scale deposition even after a month-long test. This air-replenishing strategy may lead to advanced long-term scalephobic materials.

Summary: The toxicity of graphene oxide (GO) in aquatic systems was evaluated using the freshwater planarian Dugesia japonica. GO not only impaired the growth of normal worms, but also inhibited the regeneration processes of regenerating worms. High concentration of GO killed all the worms. Mechanistic analysis suggests that GO disturbed the antioxidative system and energy metabolism, causing oxidative damage and retardance of neuron regeneration.

Summary: The development of nanotechnology and the widespread use of metal-based nanoparticles in consumer products have led to the release of nanoparticles into soil, particularly in agricultural systems. This review examines the interaction between metal-based nanoparticles and the plant rhizosphere microenvironment, using examples of commonly used nanoparticles such as Ag NPs and ZnO NPs. Factors such as soil pH, organic matter, microorganisms, and rhizosphere exudates can influence the behavior of nanoparticles in the environment. Moreover, nanoparticles can alter the soil chemistry and microbial properties in the rhizosphere, subsequently affecting their behavior and biological effects.

Summary: As antimicrobials, graphene materials (GMs) have potential advantages over traditional antibiotics. The antibacterial mechanism of GMs, whether it originates from parallel or perpendicular interactions or a combination of both, remains unclear. This study demonstrates that GMs with high surface oxygen content (SOC) predominantly attach in parallel to bacterial cell surfaces in suspension. The interaction mode shifts to perpendicular when the SOC reaches a threshold of around 0.3. These findings help to understand the different physical mechanisms leading to the antibacterial activity of GMs.

Summary: As antimicrobials, graphene materials (GMs) have potential advantages over traditional antibiotics due to their physical mechanisms of action, which reduce the chance of microbial resistance. This study shows that GMs with high surface oxygen content (SOC) primarily attach in parallel to the bacterial cell surface, while the interaction mode shifts to perpendicular when the SOC reaches a certain threshold. The rigidity of GMs is closely related to these distinct interaction modes. By understanding the interaction mode of GMs with bacteria, the antibacterial activity of GMs can be better understood.

Summary: The use of catalyst materials as biological fillers in wastewater treatment offers a new approach to enhance microbial degradation and achieve economic and energy saving benefits. In this study, the commonly used catalyst/carrier gamma-Al2O3 is used as a filler to treat kitchen-oil wastewater with low biodegradability, resulting in a COD removal rate of approximately 50%. The complexation of cationic vacancies on the surface of Al2O3 with extracellular polymeric substances (EPS) secreted by microorganisms in wastewater leads to the polarization of electron distribution on the biofilm. This enables efficient degrading bacteria to be enriched at the reaction interface, allowing them to obtain electrons and maintain electron dynamic balance, ultimately enhancing the degradation of pollutants. The aluminum vacancies on the surface of Al2O3 accelerate the microbial degradation process. The cationic vacancies in the catalyst structure facilitate the acquisition of exogenous electrons by microorganisms without the need for external energy, providing a new idea for improving wastewater degradation using catalytic fillers.
