AI Article Synopsis
- The study introduces an eco-friendly method for creating Laser-Induced Graphene (LIG) supercapacitor electrodes using abundant silver nanoparticles (AgNPs).
- LIG was produced via a CO laser technique on polyimide, with AgNPs applied using drop-coating from plant extracts and screen-printing with commercial Ag-ink.
- The resulting supercapacitors exhibited excellent performance, with screen-printed electrodes achieving higher specific capacitance and energy density, and showed potential anti-fungal properties against Candida sp.
Article Abstract
This study presents a simple and an environmentally friendly approach to make Laser-Induced Graphene (LIG) based supercapacitor electrodes anchored with abundant Silver Nanoparticles (AgNPs). LIG, was synthesized using a CO laser writing technique on polyimide substrate. The LIG-Ag composite was prepared using two techniques, drop-coating, and screen-printing. Ag nanoparticles prepared using the plant extract of Swietenia Macrophylla was utilized to drop-coat AgNP on LIG substrate. Screen-printing was done by using a commercial Ag-ink and a suitable mesh. The supercapacitor made from screen-printed electrodes and supercapacitor made form drop-coated electrodes showed a high specific capacitance of 118 mF/cm, 38 mF/cm, and a high energy density of 2.42 mWh/cm, 0.05 mWh/cm respectively. The screen-printed composite of LIG and AgNP was further studied for its anti-fungal properties and proved to be effective against Candida sp.

The resistance of pathogenic bacteria to various clinical antibiotics is the major problem in treating bacterial keratitis. Dimethyl fumarate (DMF) has good anti-fungal and anti-inflammatory effects in fungal keratitis, but its effect on bacterial keratitis is unclear. This study aims to investigate DMF's anti-inflammatory and antibacterial effects.

This research focused on the design and characterization of two new transition metal complexes, NiMetPhe and CuMetPhe, derived from Methionine (Met) and 1,10-phenanthroline (Phe), coordinated with Ni(II) and Cu(II) ions, respectively. Structural elucidation through analytical techniques, Conductivity, Elemental analysis, FTIR spectra, Electronic spectra, magnetic moment, Mass spectra, and Thermal degradation, confirmed their octahedral geometries with the formulas [Ni(Met)(Phe)(Cl)(H₂O)] and [Cu(Met)(Phe)(Cl)(H₂O)]. Thermal analysis revealed their stability and decomposition patterns, while DFT calculations validated the structures and provided insights into quantum chemical parameters such as HOMO-LUMO energies, molecular orbitals, and electronic distributions.

Article Synopsis
- - This study investigates Fe(III) and Co(II) complexes synthesized from Albendazole and Norfloxacin, highlighting their thermal stability, low water solubility, and neutral conductivity characteristics that make them suitable for various applications.
- - Spectroscopic analyses (FTIR and UV-Vis) confirm strong ligand-metal interactions and reveal octahedral geometries; the complexes exhibit a 1:1:1 stoichiometry and substantial thermal stability alongside unique decomposition behaviors.
- - DFT calculations indicate that the metal complexes have reduced energy gaps compared to the original ligands, suggesting increased reactivity and biological activity, which enhances their antibacterial, anti-fungal, and anti-inflammatory properties beyond those of standard antibiotics.
