The present investigation aims to optimize the effect of biochar and zeolite-based nano composites (Zn and Fe) on the various factors such as nutrient content and nutrient uptake and Agronomic fortification of Zn and Fe in rice. Seven types of completely randomized design treatment were examined using Aduthurai-43 rice (ADT 43) with three replications, namely, Tr-1 – RFD NPK(120:40:40) (Control), Tr-2 – RFD + FeSO4 at 25 kg·ha−1 + ZnSO4 at 25 kg·ha−1, Tr-3 – RFD + nano FeO + nano ZnO foliar at 500 ppm, Tr-4 – RFD + 1 g·kg−1 of nano zeolite composite, Tr-5 – RFD + 1 g·kg−1 of nano biochar composite, Tr-6 – RFD + nano FeO + nano ZnO foliar each at 500 ppm + nano zeolite composite, and Tr-7 – RFD + nano FeO + nano ZnO foliar each at 500 ppm + 1 g·kg−1 nano biochar composite. To determine the major and micro nutrient contents, grain samples and straw samples (harvest) were collected and examined using two acid extract, prepared from H2SO4 and HClO4 solution with 5:1 ratio. Among the treatments, Tr-7 significantly increased the NPK content of 0.99, 0.30 and 0.69 and Zn and Fe content by registering 22.4 and 246 mg·kg−1 of Zn and Fe, respectively, by grain and 50.7 and 241 mg·kg−1, respectively, by straw.

A theoretical study of the model dyad and triad complexes of general formula PG(HX), PG(Y)− and PG(HX)(Y)− (HX = HF, HCl and Y = F−, Cl−, C≡N−, N≡C−) has been carried out using density functional theory at B3LYP/6-311++G(2d,2p) computational level and basis set. Four distinctive non-covalent interaction patterns, including pnictogen bond (PnB), tetrel bond (TtB), chalcogen bond (ChB), and hydrogen bond (HB), were found for complex formation between phosphangulene (PG) with CN−, NC−, F−, Cl− anions and HF, HCl neutral molecules. Each HX and Y component can interact on the apex or at basal sites of the PG molecule and result in PG(HX)a(Y)b− or PG(Y)a(HX)b− aggregates. From the anticipated models, stabilities of the PG(CN)a(HF)b−, PG(NC)a(HF)b−, PG(F)a(HF)b−, PG(F)a(HF)b−, and PG(Cl)a(HF)b− triads are greater than other types. The electron release of PG to the HX molecules helps it to take electron from Y ions, thus PG(HX)(Y)− triads show greater stability and considerable cooperative effect relative to corresponding dyad adducts. Natural bond orbital theory (NBO) and Bader’s theory of “atoms in molecules” (AIM) methods have been applied to analyze the intermolecular interactions. Strong correlations have been observed between stabilities and charge transfer (qCT) in the analyzed systems.

This study focuses on the design, synthesis, and comprehensive biological evaluation of novel quinazoline derivatives as potential therapeutic agents. The structures of nine synthesized compounds were confirmed using spectral methods such as infrared (IR), proton nuclear magnetic resonance (1H NMR) spectroscopy, and elemental analysis. These compounds were assessed for antimicrobial, antioxidant, and anticancer activities against human cancer cell lines including hepatocellular carcinoma (HepG-2), breast cancer (MCF-7), and colorectal carcinoma (HCT-116). Among them, Compounds 8 and 9 exhibited remarkable biological activities. Both compounds demonstrated significant antimicrobial and antioxidant effects, alongside potent antiproliferative activity against (HepG-2), breast cancer (MCF-7) and colorectal carcinoma (HCT-116) cell lines. Notably, Compound 8 showed superior cytotoxicity with IC50 values of 30.81, 53.41, and 76.73 µM against HepG-2, MCF-7, and HCT-116 cells, respectively, outperforming Compound 9. Molecular docking studies corroborated these results, revealing strong binding affinities of Compounds 8 and 9 to key protein targets implicated in antimicrobial and anticancer mechanisms, including Escherichia coli DNA gyrase, Staphylococcus aureus dihydropteroate synthase (DHPS), CDK2 and EGFR. Furthermore, in-silico ADMET predictions indicated favorable drug-likeness and low toxicity risks, aligning with Pfizer’s drug design guidelines. Overall, Compounds 8 and 9 emerge as promising leads with broad-spectrum therapeutic potential for pharmaceutical and food industry applications.

This study focuses on the synthesis of six novel thioether derivatives with potent antimicrobial activity against Ralstonia solanacearum, the causative agent of tobacco bacterial wilt. This disease, which has caused significant economic losses, has become increasingly resistant to traditional bactericides. In response, the study investigates the potential of thioether derivatives, known for their broad spectrum of biological activities, as eco-friendly alternatives. Through SEM observations, molecular docking, and DFT calculations, we identified DHFR as a potential target for these compounds, particularly highlighting compound R4, which showed superior activity compared to conventional controls. Additionally, toxicity predictions and ADME simulations suggest that compound R4 could be a promising, safe agricultural antimicrobial agent. This research aims to expand the range of agricultural chemical frameworks and contribute to the development of more effective and environmentally friendly solutions for pest and disease control.

To enhance the photovoltaic attributes of organic solar cells, six new molecules (A-D-A type) are tailored through end-capped modification of the existing DNO15T molecule. To evaluate their properties, various computational calculations have been performed using density functional theory (DFT) with B3LYP/6–31G(d,p) functional. We studied several geometrical attributes such as density of states (DOS), dipole moment, excitation and binding energy, open circuit voltage (VOC), fill factor, molecular electrostatic potential, alignment of frontier molecular orbitals, transition density matrix (TDM), reorganizational energy, molecular planarity, deviation of planarity of all the tailored molecules (DN1–DN6) along with the reference DNR. NCI graphs and isosurfaces were additionally employed to analyze their non-covalent interactions. These newly designed molecules exhibited noteworthy enhancements in optoelectronic and performance-based metrics than the reference. Almost all molecules showed a bathochromic shift in their absorption profile, with the value of λmax ranging from 612 to 818 nm in chloroform solvent. A remarkable reduction in energy loss value has also been observed in tailored molecules except DN6. New end-capped molecules DN1, DN2, DN3, and DN6 exhibited less bandgap value than the reference. Similarly, DN3–DN5 has remarkable improvements in the value of open circuit voltage and fill factor. In short, almost every newly designed molecule has showcased remarkable outcomes in terms of numerous assessed attributes.

Black phosphorus (BP), a two-dimensional (2D) layered material, has emerged as a highly promising candidate for next-generation electrochemical biosensing platforms. Its unique combination of a layer-tunable direct bandgap, high charge carrier mobility, and pronounced in-plane anisotropy distinguishes it from other 2D materials such as graphene and transition metal dichalcogenides. These intrinsic properties render BP highly responsive to local electronic perturbations, enabling sensitive transduction for low-abundance biological targets. However, practical deployment is severely hampered by rapid degradation under oxygen, water, and light. This review is primarily focused on BP-enabled electrochemical biosensing, emphasizing stability engineering, surface functionalization for biointerfaces, and device integration toward flexible and wearable sensing; imaging or drug-delivery studies are discussed only when they provide transferable stabilization or biocompatibility insights. We analyze BP degradation mechanisms, then compare stabilization strategies with explicit attention to the tradeoffs between physical encapsulation and chemical functionalization (covalent versus non-covalent). We next summarize electrochemical detection across representative analyte classes, spanning small molecules (e.g. neurotransmitters) to macromolecular biomarkers (e.g., nucleic acids and proteins), and we close by outlining wearable integration routes and the remaining barriers for real-world operation in complex biofluids and scalable manufacturing.

Its unique combination of a layer-tunable direct bandgap, high charge carrier mobility, and pronounced in-plane anisotropy distinguishes it from other 2D materials such as graphene and transition metal dichalcogenides. These intrinsic properties render BP highly responsive to local electronic perturbations, enabling sensitive transduction for low-abundance biological targets.

The development of structurally diverse heterocyclic frameworks remains a cornerstone in the search for new antimicrobial agents. In this work, four sulfur-bridged heterocyclic scaffolds (S1–S4) featuring thiazole, thiadiazole, pyridine, and triazine cores were synthesized using a one-pot base-promoted nucleophilic substitution strategy facilitated by phase-transfer catalysis. Structural elucidation was achieved using spectroscopic techniques, including FT-IR, UV-Visible, 1H,13C NMR, and ESI mass spectrometry. Single-crystal X-ray diffraction data for scaffold S4 confirmed its symmetrical, rigid architecture. The electronic absorption spectra revealed dominant π → π* transitions, consistent with high molecular planarity and delocalized electronic systems. Further insight into the electronic properties of S4 was obtained through density functional theory (DFT) calculations, which supported its extended conjugation and electron-donating potential. Antibacterial studies showed all scaffolds displayed varying inhibition against both Gram-positive and Gram-negative strains, with S4 consistently exhibiting the largest inhibition zones. Although Ciprofloxacin exhibited larger inhibition zones, the consistent measurable activity of S4 highlights it as a promising lead scaffold for future antibacterial development. The favorable performance of S4 is attributed to its highly conjugated structure and physicochemical properties, underscoring the importance of scaffold design in medicinal chemistry. Future molecular docking studies will be undertaken and correlated with in vitro antibacterial results to provide deeper insights into binding interactions and structure–activity relationships.

In this study, a series of novel thiochroman-4-one derivatives incorporating a semicarbazone functional group were successfully synthesized and thoroughly characterized via1H NMR,13C NMR, and HRMS analyses. Biological evaluations revealed that the synthesized compounds 6a–6k exhibited moderate in vitro antioxidant effects, as demonstrated by their ability to scavenge DPPH and ABTS radicals, along with notable α-glucosidase inhibition. Among them, compound 6h stood out with significant in vitro inhibitory potency against α-glucosidase, yielding an IC50 value of 84.65 µg/mL, which was substantially lower than that of acarbose (237.48 µg/mL). The molecular docking analysis revealed that compound 6h interacts strongly with the active site of human intestinal α-glucosidase (PDB ID: 3TOP) via several binding interactions, exhibiting a binding energy of −8.6 kcal/mol. Moreover, the predicted ADMET properties and drug-likeness evaluation suggest that compound 6h possesses promising pharmacokinetic characteristics and a low toxicity risk, fulfilling essential requirements for prospective therapeutic candidates.
