Abstract	Nitrogen (N) and subsurface drainage water management are crucial and challenging components of sustainable crop production on poorly drained claypan soils. During extreme precipitation events, N fertilizer management is difficult in a corn (Zea mays L.)–soybean (Glycine max L.) rotation that balances productivity and environmental quality. This 4‐year (2018–2021) experiment was conducted on a poorly drained soil to examine the interactive effects of drainage (subsurface tile drainage [SD] and no drainage [ND]) and corn N fertilizer treatments (non‐treated control [NTC], fall‐applied anhydrous ammonia [AA] at 190 kg N ha⁻¹ with nitrapyrin [fall AA + NI], pre‐plant AA [spring AA] at 190 kg N ha⁻¹, and top‐dressed urea [TD urea] as 42 kg N ha⁻¹ SuperU and 126 kg N ha⁻¹ ESN as a 25:75% granular blend) on yield and nutrient uptake. Corn grain yield was 1.22–1.53 Mg ha⁻¹ greater with fertilizer treatments in SD compared to ND. Drought conditions in 2018 lowered corn grain yield compared to 2020. Average over 2 years, corn yield in SD soils was ranked as spring AA > fall AA + NI > TD urea > NTC. While soybean yield following corn was 13% greater in the NTC compared to TD urea. The SD treatment increased soybean yield by 0.6–2 Mg ha⁻¹ compared to ND. This study results showed that fall AA + NI produced corn yields similar to spring AA in SD and ND soils in temperate humid climatic conditions.

Abstract	The characterization of protein-protein interactions (PPIs) is fundamental to the understanding of biochemical processes. Many methods have been established to identify and study direct PPIs; however, screening and investigating PPIs involving large or poorly soluble proteins remains challenging. Here, we introduce ReLo, a simple, rapid, and versatile cell culture-based method for detecting and investigating interactions in a cellular context. Our experiments demonstrate that ReLo specifically detects direct binary PPIs. Furthermore, we show that ReLo bridging experiments can also be used to determine the binding topology of subunits within multiprotein complexes. In addition, ReLo facilitates the identification of protein domains that mediate complex formation, allows screening for interfering point mutations, and it is sensitive to drugs that mediate or disrupt an interaction. In summary, ReLo is a simple and rapid alternative for the study of PPIs, especially when studying structurally complex proteins or when established methods fail.

Abstract	Developing behavioral policies designed to efficiently solve target-search problems is a crucial issue both in nature and in the nanotechnology of the 21st century. Here, we characterize the target-search strategies of simple microswimmers in a homogeneous environment containing sparse targets of unknown positions. The microswimmers are capable of controlling their dynamics by switching between Brownian motion and an active Brownian particle and by selecting the time duration of each of the two phases. The specific conduct of a single microswimmer depends on an internal decision-making process determined by a simple neural network associated with the agent itself. Starting from a population of individuals with random behavior, we exploit the genetic algorithm NeuroEvolution of augmenting topologies to show how an evolutionary pressure based on the target-search performances of single individuals helps to find the optimal duration of the two different phases. Our findings reveal that the optimal policy strongly depends on the magnitude of the particle’s self-propulsion during the active phase and that a broad spectrum of network topology solutions exists, differing in the number of connections and hidden nodes.

Abstract	The present research is targeted at E. cardamomum-derived TiO₂-photocatalyst synthesis, reporting for the first time. The structural properties observed from the XRD pattern reveal that EC:TiO₂ has an anatase phase and crystallite size is assessed by Debye-Scherrer's method (3.56 nm), WH-method (3.30 nm), and Modified-Debye-Scherrer's method (3.27 nm). An optical study by the UV–Vis spectrum shows strong absorption at 313 nm, and the corresponding band gap value is 3.28 eV. The topographical and morphological properties revealed by SEM and HRTEM images, elucidate the formation of multi-shaped particles of nano-size. Further, the phytochemicals on the EC:TiO₂ NPs' surface are confirmed by the FTIR spectrum. The photocatalytic activity is well studied under UV light towards Congo Red dye, along with an effect of the dose of catalyst. EC:TiO₂ (20 mg) has exhibited high photocatalytic efficiency up to 97% for 150 min of exposure due to the morphological, structural, and optical properties. CR degradation reaction exhibits pseudo-first-order kinetics, displaying a rate constant value of 0.01320 min⁻¹. Reusability investigations reveal that after four photocatalysis cycles, EC:TiO₂ has an effective efficiency of >85%. Additionally, EC:TiO₂ NPs have been assessed for antibacterial activity and show potential against two bacterial species (S. aureus and P. aeruginosa). Therefore, these research outcomes from the eco-friendly and low-cost synthesis, are promising for the use of EC:TiO₂ as a talented photocatalyst towards the removal of crystal violet dye as well as an antibacterial agent against bacterial pathogens.

Abstract	The present work encompasses a simple strategy to synthesize highly porous TiO₂ by incorporating PANI polymer into the sol-gel chemistry of Titanium dioxide/Titanium (IV)-iso-propoxide (TiO₂/TTIP). A series of TiO₂ samples by varying wt.% of PANI, have been synthesized. A probable growth mechanism has been presented for the formation of a porous ginger-like nanostructure of TiO₂-PANI (TP). HRTEM images reveal that the particle size range is 6–16 nm for pristine TiO₂ and 5–13 nm for TP samples. XPS analysis confirms the presence of the hydrogen bonds in-between surface hydroxyl groups (Ti–OH) of TiO₂ and the protonated nitrogen of PANI. UV–visible absorption study reveals a small shift towards longer wavelength for TP8 sample than that of pristine TiO₂ (λₘₐₓ = 314 nm) as well as reduction in Eg value from 3.02 eV to 2.89 eV. FTIR results confirm the successful interaction of PANI and TiO₂. BJH and BET analysis confirms an increase of porosity in TP8 sample with an average pore volume of 0.36 cm³ g⁻¹. High photocatalytic activity (98.77%) towards Methylene blue dye degradation is observed for TP8 sample having 8 wt% of PANI and it is explained through the combined effect of structural porosity of TiO₂ and synergic effect of PANI. The Kₐₚₚₐ value at pH 11 (0.01372 min⁻¹) is found to be 7.84-folds higher than that of the photocatalytic reaction at pH 3 (Kₐₚₚₐ = 0.00175 min⁻¹). While pristine TiO₂ exhibits the minimum removal efficiency (89.57%) with Kₐₚₚₐ of 0.00756 min⁻¹. Kₐₚₚₐ value of catalysis reaction for TP8 is found to be almost 2-fold higher than pristine TiO₂. Quantum Yield value for TP8 is found to be 3.59 × 10⁻⁴ molecules photon⁻¹. This high Quantum Yield value of present photocatalytic system explicates the low energy consumption for the treatment of textile dye pollutant. Additionally, STY value (1.79 × 10⁻⁵ molecules photon⁻¹ mg⁻¹) confirms the outstanding mineralization strength of TP8 by a unit mass for high amounts of MB dye per unit time. Thus, the present study offers an excellent photocatalyst i.e., TP8 having 8 wt% of PANI for the degradation of MB dye.

Abstract	The present study portrays a facile, cost-effective, and environmentally benign way for the preparation of TiO₂ nanoparticles utilizing C. limon extract, which possesses phytochemicals as reducing and stabilizing agents. Structural characterization by XRD reveals that C. limon/TiO₂ NPs exhibit anatase-type tetragonal crystallinity. An average crystallite-size is calculated using Debye Scherrer's method (3.79 nm), Williamson–Hall plot (3.60 nm), and Modified Debye Scherrer plot (3.68 nm), which are very closely intercorrelated. The absorption peak at 274 nm (UV–visible spectrum) corresponds to the bandgap (Eg) value of 3.8 eV. The existence of different phytochemicals containing organic groups like N–H, C=O, and O–H, has been elucidated from FTIR along with Ti–O bond stretching at wavenumber 780 cm⁻¹. Micro-structural investigations of TiO₂ NPs using FESEM and TEM display different geometrical configurations involving spherical, pentagonal, hexagonal, heptagonal and capsule-like structures. BET and BJH analysis show mesoporous characteristics of synthesized nanoparticles with specific surface-area (97.6 m² g⁻¹), pore-volume (0.018322 cm³ g⁻¹), and mean pore-diameter (∼7.5 nm) values. In adsorption studies, the influence of reaction parameters, i.e., catalyst dosage and contact-time, for removal of Reactive Green dye is explored along with Langmuir and Freundlich models. The highest adsorption capability is ∼219 mg g⁻¹ for green dye. TiO₂ displays an excellent photocatalytic efficiency of ∼96% towards the degradation of reactive green dye within 180 min and excellent reusable performance. C. limon/TiO₂ is found to have an outstanding performance with a quantum yield value of 4.68 × 10⁻⁵ molecules photon⁻¹ for Reactive Green dye degradation. Additionally, synthesized nanoparticles have exhibited antimicrobial activity against gram-positive Staphylococcus aureus (S. aureus) and gram-negative Pseudomonas aeruginosa (P. aeruginosa) bacteria.
