Summary: In this study, an Au@Cu2O heterostructure with multienzyme-like activities is designed, which shows significantly improved antioxidant capacity compared to pure Cu2O. The heterostructure can scavenge highly cell-damaging secondary reactive oxygen species (ROS), namely center dot OH. The presence of oxygen vacancies, redox couples, and electron deficiency at the metal-semiconductor interface of the heterostructure enables enhanced adsorption and activation of ROS and avoids the production of center dot OH.

Summary: Rapid identification and analysis of pesticide residue on real-world sample by a portable platform is of growing interest for monitoring food safety and safeguarding human health. Herein, we developed a robust surface-enhanced Raman spectroscopy (SERS) sensor based on ZrO2@TiO2/Ag substrate for the analysis of pesticide residues. The synergetic effects of the metal organic framework (MOF)-derived porous ZrO2@TiO2 heterostructure induced charge transfer enhancement and the electromagnetic enhancement from the plasmonic silver nanoparticles (AgNPs) hotspot generate significant SERS enhancement signal. The SERS substrate exhibits superior long-term stability and signal homogeneity for SERS quantitative analysis. The platform has the capability to detect not only model molecule of 4-ATP but also pesticides of triazophos and fonofos at the extremely low concentration of 10(-8) M. Moreover, we simulate the quantitative detection of pesticide residue on real objects by spraying pesticides on dendrobium and chrysanthemum leaves, followed by transferring to the SERS platform to perform analysis. The nearly linear fitting curve with a wide concentration range suggests the superior qualitative detection capability. Remarkably, two components and three components of the pesticides are readily identified in a rapid way. The approach provides the rapid analysis, low-cost device, and portable and quantitative pesticide identification and offers a clear path to multicomponent analysis at a trace level.

Summary: This study investigates the surface wrinkling and post-wrinkling bifurcation using a micropattern configuration at a 3-dimensional level. The presence of the pattern allows for the regulation of local strain energy distribution, enabling a programmable transition from wrinkles to post-wrinkling morphologies. Finite element analysis reveals that the post-wrinkling bifurcation is caused by stress concentration at the edge of the micropattern. This finding has important implications for designing future smart surfaces, sensors, and actuators.

Summary: The one-step hydrothermal reduction method was used to synthesize platinum nanoparticle-modified molybdenum disulfide-silica nanocomposites with excellent peroxidase-like activity. These nanocomposites showed the ability to decompose hydrogen peroxide into hydroxyl radicals and superoxide radicals, and were able to oxidize colorless 3,3',5,5'-tetramethylbenzidine into a blue oxidation product. A colorimetric sensing device for hydroquinone was developed using the nanocomposites, with a linear range of 0.5-9 μM and a low limit of detection. This sensing platform exhibited satisfactory sensitivity and selectivity in tap water and river water samples.

Summary: Terephthalic acid reformed Al/Zn metal organic nanoflake functionalized with trie-thylamine (T-AlZn) exhibits remarkable performance in removing trace lead (II) ions (Pb2+), with an adsorption equilibrium reached within 35 min and a removal rate ≥ 97%. After four regenerations, the decline in removal rates of T-AlZn for Pb2+ is only 16.73%. The adsorption of T-AlZn for Pb2+ follows the Langmuir isotherms model and pseudo-second-order dynamics model, with the utmost adsorption competence of 215.27 mg g-1. T-AlZn adsorbent shows a bright prospect in the adsorption for Pb2+ and is a considerable candidate in the disposal of industrial sewage.
