Exploring novel p-hydroxyphenylpyruvate dioxygenase (EC 1.13.11.27, HPPD) inhibitors has become one of the most promising research directions in herbicide innovation. On the basis of our tremendous interest in exploiting more powerful HPPD inhibitors, we designed a family of benzyl-containing triketone-aminopyridines via a structure-based drug design (SBDD) strategy and then synthesized them. Among these prepared derivatives, the best active 3-hydroxy-2-(3,5,6-trichloro-4-((4-isopropylbenzyl)amino)picolinoyl)cyclohex-2-en-1-one (23, IC50 = 0.047 μM) exhibited a 5.8-fold enhancement in inhibiting Arabidopsis thaliana (At) HPPD activity over that of commercial mesotrione (IC50 = 0.273 μM). The predicted docking models and calculated energy contributions of the key residues for small molecules suggested that an additional π–π stacking interaction with Phe-392 and hydrophobic contacts with Met-335 and Pro-384 were detected in AtHPPD upon the binding of the best active compound 23 compared with that of the reference mesotrione. Such a molecular mechanism and the resulting binding affinities coincide with the proposed design scheme and experimental values. It is noteworthy that inhibitors 16 (3-hydroxy-2-(3,5,6-trichloro-4-((4-chlorobenzyl)amino)picolinoyl)cyclohex-2-en-1-one), 22 (3-hydroxy-2-(3,5,6-trichloro-4-((4-methylbenzyl)amino)picolinoyl)cyclohex-2-en-1-one), and 23 displayed excellent greenhouse herbicidal effects at 150 g of active ingredient (ai)/ha after postemergence treatment. Furthermore, compound 16 showed superior weed-controlling efficacy against Setaria viridis (S. viridis) versus that of the positive control mesotrione at multiple test dosages (120, 60, and 30 g ai/ha). These findings imply that compound 16, as a novel lead of HPPD inhibitors, possesses great potential for application in specifically combating the malignant weed S. viridis.

A setaria viridis-like TiN nanofibers with hierarchical structure (noted HSTFs) is synthesized via electrospinning and hydrothermal method. The results reveal that the synthesized HSTFs nanofibers belong to the TiN crystalline phase. The surface of the fibers is uniformly distributed with pore-structured nanorods, which have an average diameter of 55 nm. The HSTFs exhibits a higher specific surface area. Comparing to the TFs||TFs symmetric supercapacitor device, the HSTFs||HSTFs device demonstrates a significantly higher specific capacitance of 177 F g −1 at a current density of 10 mA g −1 . The enhanced electrochemical performance is attributed to the hierarchical and porous structure of TiN fibers, which provides a larger surface contact area and more active sites. This structure is conducive to the construction of a conductive network and improves the reversible proton insertion and chemisorption of electrolyte-electron. This research presents a promising approach for the design and synthesizes of high-performance supercapacitor materials.

Biomimetic Setaria viridis interlocking structures for piezoresistive sensors use low-cost fabric and PPy. • The sensor has 33.45 kPa⁻¹ sensitivity (≤2.3 kPa), 40 kPa detection range and 0.052 g detection limit. • Simple fabrication (surface layer removal + gas-phase polymerization) ensures low cost and scalability. • It enables uses in motion monitoring, sound discrimination, pressure mapping, Morse code transmission. A biomimetic piezoresistive material based on a Setaria viridis-inspired interlocking structure was fabricated from air interlayer fabric and polypyrrole (PPy) for application in flexible pressure sensors featuring high-sensitivity and low-detection-limit. A high-resilience air interlayer fabric was selected for the design. One side of the fabric substrate was removed. The middle support layer creates a high-specific-surface-area fiber layer with a biomimetic Setaria viridis-like structure. Two biomimetic Setaria viridis fabrics are stacked support-layer-to-support-layer. The formed interlocking structure is sandwiched between two copper foil electrodes to build a sandwich architecture. External pressure concentrates stress on the fibers of the support layer. This flexible sensor achieves a wide detection range of 40 kPa and an ultrahigh sensitivity of 33.45 kPa −1 below 2.3 kPa. Piezoresistive sensors based on the biomimetic Setaria viridis interlocking structure have achieved promising applications in human motion monitoring, sound discrimination, spatial pressure distribution, and Morse code-related information transmission.

Biomass-derived carbons are promising supports for electrochemical CO 2 reduction (ECO 2 R) due to their natural abundance and renewability. However, achieving high selectivity and industrially relevant current densities with biomass-derived carbon catalysts remains challenging. Here, inspired by the porous microchannel and bristle-like structure of Setaria viridis (SV), a one-pot co-pyrolysis strategy was employed to synthesize hierarchically porous silver-decorated nitrogen-doped carbon catalysts. The SV-derived carbon, combined with optimized nitrogen doping and silver decoration (Ag/N-SV1), yields a hierarchically porous carbon catalyst with tuned electronic states that enhance CO 2 adsorption and stabilize the ⁎ COOH intermediate, thereby improving CO selectivity. In an H-cell, Ag/N-SV1 achieved a CO Faradaic efficiency (FE CO ) of 89% with a partial current density (j CO ) of -6.7 mA cm -2 at -0.98 V vs. RHE, while maintaining stable operation for 20 hours. In contrast, nitrogen-doped SV (N-SV1) primarily produced formate, highlighting the critical role of Ag in CO selectivity. Furthermore, the hydrophobically treated Ag/N-SV1 gas diffusion electrode (GDE) achieved a j CO of -123 mA cm -2 in the flow cell, demonstrating scalability and practical promise. Density functional theory (DFT) calculations revealed that Ag-N coordination lowers the energy barrier for ⁎ COOH formation, resulting in enhanced CO selectivity. This study highlights Setaria viridis as a renewable and sustainable biomass precursor, validating the co-pyrolysis approach as an effective strategy for designing cost-effective Ag-N materials for sustainable electrochemical applications.

With increasing water pollution and human health problems caused by oily wastewater, the fabrication of oil–water separation materials has become an urgent task. However, most of the reported materials have a single function and poor performance. In this paper, a multifunctional zinc oxide/polyaniline/polyacrylonitrile (ZnO/PANI/PAN) nanofibrous membrane with needle-like ZnO nanorods was prepared by in situ synthesis of PANI and a hydrothermal reaction on a highly stable self-standing PAN blow-spinning fibrous membrane. Due to the electronic synergistic effect of ZnO and PANI, the fibrous membrane exhibits excellent antibacterial activity and visible-light degradation ability of organic dyes. Moreover, the micro-/nanosized pores of the ZnO/PANI/PAN fibrous membranes also guarantee its excellent emulsion separation performance, including an ultrahigh surfactant-free emulsion permeate flux (∼8597.40 L/(m2 h)), ultrahigh surfactant-stabilized emulsion permeate flux (∼2253.50 L/(m2 h)), and excellent separation efficiency (above 99%). Furthermore, the composite membrane maintains stable underwater superoleophobicity and hydrophilicity under adverse conditions, shows good biological safety, and is harmless to the water environment. These excellent properties endow the ZnO/PANI/PAN nanofibrous membranes with great potential in treating oily wastewater.

Transition metal selenides are widely used in electrocatalysis on account of high electrical conductivity , good stability and low cost. In this study, using nickel-cobalt layered double hydroxide (NiCo-LDH) as precursor, a simple two-step method was used to prepare three-dimensional (3D) Setaria viridis-like NiCoSe 2 nanoneedles arrays on nickel foam (NiCoSe 2 NNA/NF). Benefiting from the abundant catalytic active sites provided by the 3D nanoneedles array structure, the covalent reciprocity between Ni, Co and Se can effectively facilitate the free movement of ions and electrons on the electrode surface. As a hydrazine sensor, the electrochemical performance of the NiCoSe 2 NNA/NF was studied by cyclic voltammetry (CV) and other electrochemical techniques , which exhibits outstanding electrocatalytic performance. When the signal-to-noise ratio is 3 (S/N = 3), the sensitivity is 16170 μA mM −1 cm −2 , the lower detection limit is 0.5 μM. It also shows well anti-interference and long-term stability. In addition, the successful applications in water environments samples also demonstrated the feasibility of the sensor. This method provides a new idea for the development of selenide-based electrochemical sensors .

Nowadays, it is very necessary to develop high-efficiency nanoadsorbents to remove drug contaminants from wastewater. Inspired by a biomimetic Setaria viridis-like structure, we provide a simple and general approach for the preparation of hydrophilic magnetic surface molecularly imprinted core–shell nanorods (HMMINs) via a two-step surface-initiated atom transfer radical polymerization in a green alcohol/water solvent mixture at room temperature, with magnetic halloysite nanotubes (HNTs, a hollow tubular structured natural clay mineral) used as nano-cores. HMMINs showed a well-defined core–shell structure with an ultra-thin imprinted film (12 nm) and hydrophilic polymer brushes (2–4 nm), where magnetic nanoparticles (11 nm) were uniformly dispersed onto the surface of halloysite nanotubes. HMMINs possess good magnetic properties and thermal stability. Surface grafting of the hydrophilic polymer brushes enhanced the adsorption selectivity and kinetics. HMMINs exhibited a large adsorption capacity (37.64 ± 1.36 μmol g−1) and fast kinetics (within 45 min) towards a typical antibiotic drug sulfamethazine (SMZ) from pure water. Adsorption isotherm and kinetics data were well described by the Freundlich isotherm model and pseudo-second-order kinetic equation, respectively. HMMINs displayed good selectivity towards SMZ as compared with other antibiotics, as well as good regeneration performance, providing a potentially practical application in the highly efficient and selective removal of antibiotic contaminants from wastewater.

The setaria viridis-like TiN fibers with efficient electromagnetic wave absorption in the whole X and Ku bands were prepared by electrospinning and hydrothermal methods. The results of XRD, Raman, and XPS suggested the presence of cubic TiN phase with TiO x N y solid solution form in fibers. The nanoneedles uniformly grew on the fibers’ surfaces along the (2 0 0) plane of cubic TiN crystal and formed a setaria viridis-like morphology. The bionic hierarchical structure gave rise to a large number of interfaces and pores, which would provide the suitable impedance matching, multiple reflections and scatterings, conductivity loss, and Debye relaxation through the synergistic effect. Hence, the superior absorption properties were achieved in the whole X and Ku bands by adjusting the fibers’ filler loading. The optimal reflection loss could reach −45.8 dB (X-band) at a thickness of 1.38 mm and −47.8 dB (Ku-band) at the thickness of 1.11 mm as the fibers absorbent contents were 20 wt% and 15 wt%, respectively. Furthermore, the effective absorption bandwidth covered the entire X and Ku bands with a thin thickness of 1.0–2.0 mm.
