Copper or nickel: metal choice steers dye capture in cellulose-MOF films
Researchers fabricated two otherwise identical cellulose-supported MOF films and found the copper-based version adsorbed more methylene blue while the nickel-based ...
Plant-made magnesium oxide nanoparticles degrade dyes and curb bacteria
Green-synthesized magnesium oxide nanoparticles from Ecbolium ligustrinum extract degraded methylene blue and basic fuchsin under sunlight and inhibited two bacterial ...
Methylene blue helps PANI/MnO2 nanocomposite electrodes keep nearly all their capacitance over thousands of cycles
A methylene blue-assisted PANI/MnO2 nanocomposite electrode retained 99.3% of its capacitance after 3000 cycles, and a symmetric supercapacitor built from ...
Carbon-Decorated Bismuth Ferrite Nanocomposite Stores Charge and Degrades Dye Under Visible Light
A sol–gel synthesized bismuth ferrite–activated carbon nanocomposite achieved a specific capacitance of 404.0 F/g with 81.38% retention over 5000 cycles ...
Dye-and-chelator bilayer electrode detects diazinon pesticide in fruit samples
A two-layer glassy carbon electrode combining electropolymerized methylene blue and 1,5-diphenylcarbazide detected diazinon in fruit extracts down to 0.093 micromolar ...
