Summary: A novel microreactor was constructed by anchoring nZVI on the rGO/PPy substrate within the microchannel, which catalyzed the Fenton-like reaction to remove >99% PNP within 50 seconds. The rGO/PPy composite substrate stabilized the nZVI, facilitated the decomposition of H2O2, and promoted the redox cycle of Fe(III)/Fe(II). The significant convection and highly-effective mass transfer within the microreactor also contributed to the ultrafast PNP removal. The rGO/PPy/nZVI microreactor shows promise for pollutant removal from water.

Summary: PdCu alloy nanocatalysts supported on NiFe layered double hydroxide (PdCu-LDHs) were prepared by a green ultrasound-assisted reduction method. The action of ultrasound dissociated hydroxyl groups on the surface of LDHs to reduce Cu2+ and Pd2+ to Cu-0 and Pd-0, promoting the synergy between Pd alloy and LDHs. The electronic effects between Cu and Pd improved the catalytic performance and stability of PdCu-LDHs for the reduction reaction of 4-NP.

Summary: This study developed a novel four-step sequential modification procedure to increase the efficiency of reductive p-nitrophenol (PNP) degradation using carbon felt (CF). The modified CF promoted the removal of PNP with high efficiency and less accumulation of toxic intermediates. Additionally, the constructed anaerobic-aerobic process with modified CF achieved further removal of carbon and nitrogen containing intermediates and partial mineralization of PNP. This study proposes a new strategy for efficient and sustainable PNP bioremediation using engineered conductive material to enhance the direct interspecies electron transfer (DIET) process.

Summary: In this study, LiFePO4 was synthesized successfully with a home-made spray drying device, and the influence of spray drying temperature on its memory effect in LIBs was investigated. The results showed that an increase in spray drying temperature strengthened the memory effect of LiFePO4, while also leading to a decrease in capacity. XRD refinement and FTIR spectra indicated that the enhancement of memory effect was attributed to the increase of Li-Fe dislocations.

Summary: Despite extensive research on nanocomposites, a fundamental theory on the interface region is still difficult to achieve. In this study, three types of nanocomposites were prepared using epoxy resin and nano-SiO2, nano-SiC, and nano-ZnO, and their dispersion characteristics and dielectric permittivity were investigated. The results showed that the reduction of permittivity at a slight filler concentration was absent at the terahertz range. The interaction between nano-SiO2 and nano-SiC particles and epoxy resin was strengthened with the modification of the silane coupling agent, while the modification of nano-ZnO particles was ineffective. The Lorentz harmonic oscillator model was used to fit the dispersion characteristics and establish the relationship between the damping constant and dielectric permittivity. The findings demonstrate the potential of terahertz time-domain spectroscopy in advancing the theory of nanocomposite dielectrics.

Summary: The development of stimuli-responsively degradable porous carriers for controlled drug release is important for clinical translation. In this study, a new type of Fe-MOF nanocrystals is engineered as an acid-degradable drug carrier and hydrogen donor. Fe-MOF nanocrystals exhibit acid-responsive degradation for H-2 generation and simultaneous drug release, and can effectively inhibit cancer metastasis and sensitize MDR cancer cells for enhanced chemotherapy. The high anti-MDR/antimetastasis efficacies and biocompatibility make Fe-MOF nanocrystals and Fe-MOF-based nanomedicine highly promising for clinical translation.

Summary: In this study, it was found that miR-4443 was significantly increased in the placentas of severe preeclamptic patients, and upregulation of miR-4443 inhibited the migration and invasion of HTR-8/SVneo cells. The inhibitory effects of miR-4443 were mediated by the suppression of MMP2. This study suggests that miR-4443 may play an important role in the pathogenesis of preeclampsia through the HB-EGF/EGFR pathway.

Summary: In this study, a polydopamine (PDA)-mediated antibacterial system was synthesized to achieve in vitro and in vivo antimicrobial activities. The surface modification of nanodiamonds (NDs) was precisely controlled using a mathematical model of PDA deposition. The synthesis conditions, including dopamine concentration, reaction time, and kinetic constant k (1), were discussed. Simulation results showed that PDA deposition was positively correlated with various factors and would be terminated if dissolved O-2 levels were inadequate. The controlled thickness of PDA layers regulated the formation of silver nanoparticles (AgNPs), resulting in enhanced Raman peaks and predicted antibacterial activity against E. coli in vitro. An optimized antibacterial hydrogel incorporating NDs-PDA/Ag was prepared and characterized. Antibacterial tests were performed to promote in vivo wound healing, and the results were confirmed by pathological and immunohistochemical-stained tissue sections. This work provides a theoretical foundation for predicting the PDA-assisted surface modification of NDs, leading to a predictable antibacterial effect and promoting in vivo wound healing.

Summary: This study investigates the influence of the flexible spacer parity of a guest photoactive liquid crystalline dimer on the photonic bandgap features of the cholesteric and twist grain boundary smectic C phases of the host molecule. The results show that the parity of the photoactive dimer affects the width of the photonic bandgap and the blue-shift of the cholesteric phase. Additionally, the parity of the dimer also affects the layer spacing and two-dimensional periodicity of the liquid crystalline phases.

Summary: This work focuses on the thermochemistry of solvation of azeotropes. The enthalpies of dissolution of azeotropes in different mediums were determined, and the impact of the structure of the azeotropes on their properties in solution was discussed. A correlation between enthalpies of solvation and molar refraction was used to determine the vaporization enthalpies of azeotropes for the first time. The results were found to be consistent with literature data, obtained using direct and calculated methods. These findings contribute to the analysis of the structure-property relationships of azeotropes.

Summary: In this study, the interactions between doped and pristine coronenes and adenine nucleobases were investigated using Density Functional Theory. The optimal configurations, adsorption energies, charge transfer, and electrical properties of each complex were calculated. It was found that doped coronene had stronger adsorption strength and charge transfer compared to pristine coronene. The stability of the complexes was attributed to non-covalent interactions in the interactive region. The change in electrical conductivity of coronenes after adsorption suggested their sensitivity towards DNA bases. The predicted energy gap and prolonged recovery time for adenine-coronene configurations indicated the potential application of pristine/doped coronene in DNA detection.

Summary: This study evaluated the adsorption of zolpidem on magnetic graphene oxide and synthesized magnetic graphene oxide adsorbents for zolpidem removal. The best magnetic nanoadsorbent was found to have a removal percentage of 87.07% at specific pH and temperature conditions. The results suggest that the removal of zolpidem is related to the surface chemistry of the adsorbent rather than the surface area of graphene oxide. The adsorbent showed excellent adsorption efficiency and magnetic behavior, making it a promising material for removing zolpidem from aqueous solutions.

The results show that volume fraction and temperature have a significant impact on the thermal conductivity, while sphericity also needs to be considered. A support vector machine regression model was created to analyze the sensitivity of the thermal conductivity to different parameters. The findings indicate that temperature, sphericity, and volume fraction are the most sensitive variables.
