In this figure, MgFe₂O₄@SiO₂ nanorods created at ambient conditions were characterized by UV-VISIBLE, TGA, XRD, FE-SEM, HR-TEM, and BET analysis to establish their physical nature. As revealed by VSM, these rods are magnetic. EDS confirms elemental composition. XRF affords fluorescence properties. These rods are capable of quickly degrading methyl orange. More details will be discussed by Prof. Radhakrishnan M. Tigote and his coworkers on page 1032–1041 in this issue.

1. The enhancement of hydrogen bond of BHI fluorophore facilitates the ESIPT process.
2. The charge redistribution is favorable for promoting the ESIPT reaction.
3. The increasement of solvent polarity favors the ESIPT behavior of the BHI system.

This work presents a novel p-type SnO₂/n-type NiWO₄ heterojunction was synthesized via simple chemical impregnation method. The obtained NiWO₄/SnO₂ possessed a p-n heterojunction structure at the contact interface. Visible light response range and carrier transmit status were successfully adjusted in heterojunction. The electron-hole pairs from photogenerated process accelerated to the degradation of Amaranth dye.

The synthesized magnetic MgFe₂O₄@SiO₂ nanorods show an optical band gap of 3.1 eV, with λmax at 334 nm and average particle size 36 nm, with FCC crystal structure. SEM & TEM confirm the rod-like structure. EDS, XRF studies reveal the presence of Si, Mg, Fe and O. The surface area, pore volume, and pore diameter are 19.2 m² g⁻¹, 2.46 cm³ g⁻¹, 5.10 nm respectively.

The CuGaO₂/g-C₃N₄ composite has been found to form a p-n heterojunction capable of generating an increased photocurrent for water reduction, compared to its isolated components. Its activity lies in the enhanced photo-generated charge transfer in the photo-catalyst. Orbital hybridization possibly enable this phenomenon, as was evidence by XPS and XAS analyses.

Modified chitosan with epichlohydrin and bidentate Schiff base ligand (CEP) was successfully synthesized, characterized and its removal ability of Pb²⁺ and Cd²⁺ ions was studied. At optimal conditions, the maximum removal percentage of Pb²⁺ and Cd²⁺ ions was found to be 95 and 79%, respectively. The adsorption process followed the second-order kinetic model for Pb(II) and the first-order kinetic model for Cd(II). In addition, the effect of interface ions was investigated and it was found that the presence of divalent cations only affected the adsorption of Pb(II) and Cd(II) using CEP. Finally, the CEP adsorbent has undergone five regeneration experiments and adsorption efficiency was reduced by about 9 and 12% for Pb(II) and Cd(II) ions, respectively.

In this study, a novel potentiometric sensor was developed for the determination of Cu²⁺ ions. The developed sensor exhibits a linear response over a wide concentration range and has a very low detection limit. In addition, the copper(II)–selective sensor has advantages such as high selectivity, short response time, low cost, good repeatability, and stability.

A method based on themodified quick, easy, cheap, effective, rugged, and safe method (QuEChERS) wasdeveloped for the determination of 6 common types of anthocyanins inblueberries using LC-MS/MS. This proposed method provided an efficient andsensitive approach for the qualitative and quantitative determination of thecommon anthocyanins in blueberry samples.

In this work, a new modified Gd₂O₃/SrFe₁₂O₁₉ nanocomposite/Schiff base chitosan was prepared, and it was characterized using FT-IR, XRD, DSC, VSM, FE-SEM, X-ray energy dispersive spectrum (EDS), and map analysis. All results confirm that the Gd₂O₃/SrFe₁₂O₁₉ nanocomposite/Schiff base chitosan was successfully prepared. EDS and map analysis predicts that all elements are well distributed to the compound. VSM shows that the title compound has high saturation magnetic of 17.35 emu/g with high coercivity of 4664 Oe. In addition, Gd₂O₃/SrFe₁₂O₁₉ nanocomposite/Schiff base chitosan was used as a new adsorbent for the removal of Pb(II) and Cd(II) ions from aqueous solution, and the results confirm that the removal efficiency of Pb(II) (98%) is higher than Cd(II) (78%) ion. At best conditions, the maximum adsorption capacity for Pb(II) is 183.75 and for Cd(II) is 146.25 mg/g. According to adsorption results, we proposed thio compound to removal of other heavy metal ions such as Hg(II), Cr(VI), and Zn(II) using the adsorption process.

The effect of the addition of EDTA in colored soft beverages was studied to prevent dye degradation by the Fenton reaction. The stability of the naphtol blue black, used as a model, was monitored by UV–visible spectrometry in the presence of FeSO₄ and H₂O₂ at pH = 3.4 and at other pHs.

3,5,6-Trichloropyridin-2-yl based molecules derivatives were synthesized. The compounds were designed to meet the urgent need for novel antimicrobial agents. Most of compounds exhibited superior antibacterial activity compared to amoxicillin. Molecular docking and ADMET parameters of the compounds were in silico computed.
