Summary: An adhesive and visualized hydrogel-based detector is designed to monitor the solar radiation dose required for plant growth by the discoloration of methylene blue (MB) under sunshine. The hybrid hydrogels prepared from photoinitiated polymerization on the graphitic carbon nitride (g-C3N4) surface and polypropylene (PP) fabrics as a substrate enable better photodegradation capability and improved mechanical properties of the hydrogel-based detector. By pasting the detector on the leaf of a plant, the radiation dose can be accurately traced from the change in color to ensure sufficient radiation for plant growth and avoid burn to the leaves under sunlight.

Summary: Air pollution caused by nitrogen oxides (NO2) from exhaust gas is a long-standing problem that requires new capture and abatement technologies. Electrochemical conversion of NO2 to value-added chemicals is a promising strategy for mitigating imbalances in the global nitrogen cycle. We propose an electrochemical cell based on an aqueous Zn||NO2 system with a nano-NiO catalyst. The cell efficiently captures and converts NO2 to NO2- and value-added NH3 while generating electric power.

Summary: The swelling behavior of PNIPMAM thin films containing magnesium salts in water vapor is investigated for their potential applications as nanodevices. In situ time-of-flight neutron reflectometry is used to probe the extent and kinetics of the swelling ratio and water content. In situ Fourier-transform infrared (FTIR) spectroscopy and two-dimensional FTIR correlation analysis are utilized to study the solvation events and enhance the sensitivity of PNIPMAM thin films. The addition of Mg(ClO4)2 or Mg(NO3)2 results in higher water uptake and thickness gain in the swollen state, with Mg(NO3)2 showing the highest relative water uptake.

Summary: In this study, a series of organic room-temperature phosphorescent (RTP) polymers with tunable color luminescence were prepared by incorporating phosphorescent rotors into polymer backbones. Experimental and theoretical calculations revealed that the various molecular conformations of the monomers are responsible for the excitation wavelength-dependent (Ex-De) RTP behavior. By gaining insights into the underlying mechanism, dynamic control of Ex-De RTP behavior was achieved through thermal energy driven molecular rotations of the monomers. These findings provide new opportunities for controlling the response behaviors of smart-responsive RTP materials through external stimuli rather than conventional covalent modification methods.

Summary: A robust aqueous solid-electrolyte interphase (SEI) is successfully constructed by introducing a ladderized heterocyclic polymer electrode into a water-in-salt electrolyte, enabling ultra-stable dual-ion storage with long-term calendar life. The sophisticated SEI composed of fluorinated/oxygenated species is formed through a proton co-intercalation process, consuming water in the solvation shell of Li+ ions to trigger the decomposition of organic anions. This new SEI formation path is expected to broaden the applications of aqueous SEI and facilitate the design of versatile electrode materials for advanced aqueous Li-ion batteries (ALIBs).

Summary: Inorganic perovskite nanosheets (Cs3Bi2I9, Cs3Sb2I9) are synthesized at the liquid-air interface by drop-casting the precursor solution with the addition of iodine. The thickness and lateral size of the nanosheets can be adjusted through the iodine concentration. The iodine repairs iodine vacancies during perovskite growth, resulting in enhanced optical and optoelectronic properties. The liquid-air interfacial growth of ultrathin perovskites provides flexibility for constructing perovskite-based heterostructures and devices at the atomic scale.

Summary: Platinum (Pt) drugs are widely used in cancer therapy, but their efficacy is compromised by side effects and drug resistance. Precise delivery and release of Pt drugs have become important with the development of immunotherapy and imaging-guided therapy. Targeted delivery of Pt drugs increases accumulation at tumor sites and enhances antitumor efficacy. Combining Pt drugs with other theranostic agents in nanosystems achieves synergistic therapy and real-time monitoring.

Summary: The influence of humidity on the resistance properties of post-treated PEDOT:PSS films was investigated. It was found that elevated humidity increased the resistance of reference samples without post-treatment, while the post-treated samples showed a reverse behavior. Morphological changes in the film, such as increased PEDOT domain distances, were observed with in situ GISAXS measurements. This led to a deterioration in interdomain hole transport and a rise in resistance. Additionally, EIS measurements revealed additional contributions of ionic charge carriers in the post-treated PEDOT:PSS films.

Summary: This study synthesized a high-molecular-weight polystyrene-b-poly(methyl methacrylate) block copolymer as a soft matrix to fabricate nanocomposites containing magnetic nanoparticles. The influence of different ratios of PMMA-coated FePt nanoparticles on the self-assembled morphology was investigated. Statistical analysis revealed that the particles mainly self-assembled inside the PMMA phase at low particle concentrations, while higher particle ratios had a negative effect on the morphology. The magnetic addressability of the nanoparticles inside the nanocomposite films was confirmed using bimodal magnetic force microscopy.
