Summary: This study aimed to investigate the feasibility of applying soaking root fertilizer to Eucalyptus urograndis seedlings by dipping the roots, and its effectiveness in improving seedling growth quality. The results showed that soaking root fertilizer had a positive effect on seedling growth and biomass, but also had some negative effects on growth height, photosynthesis, and root morphology. Compound fertilizers showed potential for high growth rate and quality. Root traits were significantly correlated with aboveground indices of seedlings, and dipping roots significantly promoted seedling growth traits.

Summary: This study investigated the effects of different sources of iron oxide nanoparticles (NPs) applied to roots and leaves on the growth and physiological responses of maize seedlings. The results showed that different sources of iron oxide NPs and root application had varying effects on maize. Root application of iron oxide NPs significantly increased the biomass of maize, while foliar application had a smaller effect. Both foliar and root applications increased the chlorophyll content, but foliar application had a more pronounced effect. Reactive oxygen species showed no significant response to the application of iron oxide NPs on maize.

Summary: La-doped α-Fe2O3 nanoparticles were synthesized by hydrothermal method, and the effects of pH value on their morphology, structure, and electrochemical stability were investigated. The La-doped α-Fe2O3 nanoparticles exhibited a uniform spherical morphology at pH = 6 and improved electrochemical stability. However, at pH = 4 and 8, the nanoparticles were agglomerated with poor dispersion.

Summary: In this study, mesoporous CeO2 nanorods were hydrothermally synthesized and a novel S-scheme heterojunction alpha-Fe2O3/CeO2 photocatalyst was constructed. The optimized S-scheme Fe2O3/CeO2 nanocomposites displayed a superior photocatalytic H2 evolution rate of 2973.2 mu molg- 1h- 1, which was 5.43 folds greater than that of CeO2 nanorods. The electron transport channels in S-scheme Fe2O3/CeO2 nanocomposites facilitated the spatial migration and separation of photocarriers. The high H2 evolution rate of the Fe2O3/ CeO2 photocatalyst was attributed to its synergistic effect, porous architecture, oxygen vacancies, small particle size and high visible light absorption ability. The durability and stability of the Fe2O3/ CeO2 nanocomposite were confirmed by the consistent H2 evolution rate after five cycles.

Summary: Au@α-Fe2O3 nanoparticles with a well-defined structure were synthesized using hydrothermal and magnetron sputtering methods. After depositing 4.6% Au, the Au@α-Fe2O3 showed a new absorption peak at 550 nm in the UV-Vis spectrum, and its bandgap decreased from 2.20 to 1.93 eV. The fluorescence intensity and electrochemical impedance of 4.6% Au@α-Fe2O3 decreased significantly, while the photocurrent increased from 0.20 to 0.56 μA cm-2. The Au nanoparticles enhanced visible-light absorption and hindered electron-hole pair recombination in Au@α-Fe2O3 particles. The photocatalytic efficiency of Au@α-Fe2O3 particles was approximately 1 times higher than that of α-Fe2O3 particles.

Summary: An optimized acetone gas sensor based on Ti3C2/alpha-Fe2O3 (TF) composite materials was synthesized using microwave and etching methods. The TF composites exhibited improved gas-sensitive performance to acetone due to the increased specific surface area and surface defects, as well as the excellent electrical conductivity and high free charges transfer ability of Ti3C2 MXene. The response of TF gas sensor to 100 ppm acetone was significantly higher than pure alpha-Fe2O3 gas sensor, with a lower detection limit of 1 ppm. The TF gas sensor also demonstrated excellent selectivity, long-term repeatability, and stability for acetone.

Summary: In this study, a magnetic photocatalyst alpha-Fe2O3/reduced graphene oxide (rGO) was developed to enhance photocatalytic efficiency under a magnetic field. The introduction of rGO improved the transfer of photogenerated carriers and the interface effect between alpha-Fe2O3 and rGO enhanced magnetization intensity. The alpha-Fe2O3/rGO composite photocatalyst demonstrated excellent photocatalytic performance, especially at a mass ratio of 10:1, and the magnetic field further improved the photocatalytic reaction.

Summary: This study reports a flotation separation method for efficiently separating coal dust from foundry dust, with enhanced results through pre-soaking assisted mechanical stirring. Pre-soaking promotes the water-absorbing swelling of clay minerals, while mechanical stirring facilitates the dissociation of foundry dust, leading to improved flotation results. The optimal stirring speed and time were found to be 2400 rpm and 30 min, respectively. This pre-soaking assisted mechanical stirring method shows great promise for promoting flotation separation and complete recycling of foundry dust.

Summary: The widespread use of engineered nanoparticles in consumer products has resulted in their increased presence in natural water systems. The transformation rates and physicochemical properties of ENPs are primarily influenced by interactions with natural organic matter, as well as parameters related to water chemistry and hydrodynamics. Future nanomanufacturing processes should consider health, safety, and environmental impacts while maintaining the functionality of consumer products.
