Summary: Rapid industrial development, vehicles, domestic activities, and mishandling of garbage are the main sources of pollutants that are destroying the atmosphere. Continuous monitoring of these pollutants is necessary for the safety of the environment and human beings. Hybrid materials containing organic and inorganic components show potential for gas sensing applications. Polymeric nanohybrids, composed of various polymeric materials and metal/metal oxide nanoparticles, exhibit better performance due to their larger surface area and synergistic effect.

This method does not require specific surface structures or functionalities on the pre-formed cores. The controlled diffusion rate of alkaline vapors regulates the growth of MOFs and encapsulation of NPs.

Summary: The exploration of high-performance NO2 sensors is important for air quality monitoring and human health. This study fabricated Au-doped ZnO@ZIF-7 core-shell nanorod arrays for sensitive and selective NO2 detection. The heterostructured ZnO-Au@ZIF-7 sensor showed excellent performance in terms of sensitivity, selectivity, anti-humidity capacity, and long-term stability. This approach combining noble metals doped semiconductor metal oxides (SMOs) and MOF filtration membranes can be extended to the development of advanced chemiresistive gas sensors.

Summary: With endogenous redox systems and multiple enzymes, living cells can store and utilize external energy through photo/ultrasonic synthesis/catalysis. In artificial systems, however, sonochemical energy is rapidly dissipated due to electron-hole pairs recombination and ROS termination. In this study, a nanohybrid (LMND@ZIF-90) is synthesized by integrating zeolitic imidazolate framework-90 (ZIF-90) and liquid metal (LM), which efficiently captures sonogenerated holes and electrons, suppressing electron-hole pairs recombination and storing ultrasonic energy for over ten days. The nanohybrid also exhibits acid-responsive release and faster dye degradation rate.

Summary: Organic-inorganic halide perovskites (OIHPs) have attracted tremendous attention due to their low cost and excellent properties. However, stability and toxicity issues in lead-based OIHPs (POIHPs) and efficiency and stability weaknesses in tin-based OIHPs (SOIHPs) have hindered their commercial application. Doping strategies for both POIHPs and SOIHPs have shown promising potential in improving these issues. This review systematically summarizes the doping strategies and provides guidance for future research, as well as discussing the doping strategies for Pb-Sn mixed OIHPs.

Summary: This study synthesized undoped, doped, and co-doped vertically aligned zinc oxide nanorods (NRs) using a sonicated sol-gel immersion method and investigated the structural, morphological, optical, and photoconductivity properties of NRs with different dopants. The results showed that the incorporation of Fe improved the growth of NRs, while the incorporation of Ag had a detrimental effect. Co-doping enhanced the light harvesting efficiency and reduced the persistent photoconductivity.

Summary: In this study, the role of Pt metal cocatalyst and hydroxyl additives in the mechanism and activity of hydrogen evolution over the PCBM/PF3T organic nanohybrid was investigated. It was found that the addition of hydroxyl additives improved the hydrogen evolution reaction (HER) performance, achieving up to 70 mmol g(-1) h(-1) (AQY = 2.0%), which is among the best results for an organic HER photocatalyst. The enhanced activity is attributed to the binding of hydroxyl additives to Pt, which facilitates proton adsorption and more efficient H-2 formation. These findings have important implications for future organic photocatalyst designs.

Summary: In this study, SnO2-rGO and N-doped SnO2-rGO nanohybrids were synthesized by a facile hydrothermal method. The synthesized nanohybrids exhibited a tetragonal rutile structure of SnO2 lattice. Various characterization techniques were used to investigate the structural, chemical, morphological and optical properties of the nanohybrids. The gas sensing properties of the nanohybrids were also studied in detail, showing excellent NO2 sensing response at low temperature and low gas concentration, as well as remarkable stability. The superior performance can be attributed to the synergetic effect of small particle size, high defect concentration and high surface area.

Summary: Recent progress in nanotechnology has led to the incorporation of small particle size quantum dots (QDs) in industrial activities and products, resulting in undesired environmental impacts. This study focuses on the removal of metal quantum dots, such as silver and gold, from industrial water samples using a coagulative method. A novel biosorbent, COFs@MagZ@AGH, was developed and showed promising results for the removal of Ag-QDs and Au-QDs. The biosorbent was characterized and optimized under various experimental factors to achieve high removal efficiency. The recovered Ag/Au-QDs@COFs@MagZ@AGH were also explored as efficient catalysts for the degradation of an antibiotic in water, showing excellent oxidative degradation efficiency. The reusability and applicability of the biosorbent and catalysts in real industrial water samples were successfully demonstrated.

Summary: The aim of this study was to investigate the influence of various StQ substituents on the luminescence, structural, and optical properties of StQ-containing copolymers. The study found that the change in the nature of the substituent affects the emission band wavelength and can cause a transition in fluorescence color. FTIR and Raman spectroscopies were used to measure the structural properties, while absorbance measurements provided the optical parameters. Computational DFT analysis supported the application of these systems in optoelectronic devices.

Summary: This study explores the use of novel Cu/ZnO/ZnAl2O4/PAAH hybrid nanomaterials as catalysts for glycerol hydrogenolysis. The structural properties of these materials, including specific surface area, Lewis acidity, sizes and dispersion of copper nanoparticles, were modulated through sol-gel processes. The presence of PAAH and aluminium during synthesis improved the dispersion and metal-support interaction. Optimization of the catalysts led to high conversions of glycerol and selectivity towards 1,2-propanediol. Furthermore, the catalysts showed recyclability potential after reactivation.

Summary: This study investigated the influence of very high pressure on the sintering temperature, phase transition, and grain growth of a 15 nm TiO2 nanopowder during Spark Plasma Sintering (SPS). In situ synchrotron X-ray diffraction was used to track the evolution of crystalline phases and crystallite size as a function of temperature at pressures of 1.5 and 3.5 GPa. Laboratory SPS experiments were also conducted using a Paris-Edinburgh press and a high-pressure module adapted to standard SPS equipment, exploring the pressure effect in the range of 76 MPa to 3.5 GPa. The results showed that highly dense nanostructured ceramics can be achieved at low sintering temperatures under very high pressure. By heating at only 560 degrees C under 1 GPa pressure, the grain growth was limited to an average size of 233 nm, and a relative density of 98% was achieved.

Summary: Ti0.5Sn0.5O2 nanoparticles of different sizes were studied under high pressure using Raman spectroscopy. The results showed a phase transition in particles with a diameter of 10 nm at 20-25 GPa, while no phase transition was observed in particles with a diameter of 5 nm up to 30 GPa. The Ti0.5Sn0.5O2 solid solution exhibited extended stability at the nanoscale, thanks to the mixing of Ti and Sn.
