ABSTRACT A new Schiff base ligand, HNMPC , was prepared and reacted with some metal ions, including Cu(II), Ni(II), Co(II), Mn(II), VO(IV). The infrared, electronic, mass, electron spin resonance, nuclear magnetic thermal elemental analysis, molar conductance, susceptibility measurements were used to characterize the complexes. ligand acts as a monoanionic tridentate ONO donor in all complexes, coordinating sites are C=O pyridone C=N, phenolate anion. All complexes exhibit octahedral configurations, results showed that ion:ligand ratio 1:2. molecular structural parameters of its determined based on DFT level implemented Gaussian 09 program B3LYP/GENECP method at 6‐311G(d,p) basis set for C, H, N, O atoms SDD (Stuttgart/Dresden) atoms. theoretical data correlated experimental results. Gram‐positive bacteria, Gram‐negative yeast, fungi test current compounds' antimicrobial activity. Investigating antitumor activity against HepG2 cell lines encouraging IC 50 values par those cisplatin . In order determine affinity binding pattern synthesized compounds toward VEGFR‐2 active site, docking studies conducted, data. Based obtained results, future work aimed synthesize category bases their derived from aminopyridine derivative diverse aldehydes ketones.

Mercury, known for its severe health and environmental impacts even in trace amounts, necessitates effective removal from water systems. This research focuses on preparation of a novel adsorbent 3,9−bis((4−amino−5−hydroxy−1 H−pyrazol−3−yl)amino)−2,4,8,10−tetraoxa−3,9−diphosphaspiro[5.5] undecane 3, 9−dioxide (PADP) Hg(II) ions adsorption. To validate functionalization steps elucidate PADP's physical chemical properties, comprehensive array assays, including FTIR, surface area, BET, TGA, 13CNMR, Mass spectra, 31PNMR and1HNMR were employed. The study systematically examined several factors controlling mercury sorption, temperature, dosage, pH, interaction time, concentration using the batch technique. Optimal sorption effectiveness was achieved at pH 5, with an time 50 min, 80 mg dose, ambient temperature. newly devised exhibited impressive adsorption capacity (qe) 357 per Litre, empirical data fitting Langmuir Dubinin−Radushkevich isotherm models. kinetics followed second-order Elovich Thermodynamic aspects, ΔGº, ΔSº, ΔHº, also investigated, providing appreciated perceptions into energetic dynamics process. Thermodynamics has shown that is both endothermic spontaneous. Additionally, occurrence other explored, highlighting selectivity modified Pyrazole – Phosphoramidate removal. PADP demonstrates superior performance removing wastewater effluents, outshining range natural synthetic adsorbents previously used this purpose. superiority evident when comparing (qo) against those adsorbents, showcasing exceptional efficacy purifying contamination.

ABSTRACT This work presents a fluorescence sensor based on nitrogen‐doped carbon dots (N‐CDs) utilized for sequential detection of Hg 2+ and TNT. The N‐CDs were produced by simple efficient hydrothermal process involving the combination black bean extract with citric acid (CA) ethylenediamine (EDA). resulting exhibit steady blue significant quantum yield 12%. We conducted thorough investigation into mechanism which NCDs is reduced in presence . Our analyses, included Stern–Volmer quenching tests, confirmed development stable complex between When NCDs‐Hg was exposed to TNT, selectively restored. “on–off–on” sensing capacity allows monitoring both demonstrating good sensitivity selectivity. has low limit (LOD) 3.1 46 nM ions TNT linear range 0–40 0–30 μM, respectively. study emphasizes potential application detecting heavy metals explosives at same time. It highlights their usefulness sophisticated environmental technologies that are suitable important applications.
