  • Nickel (Ni) can help soybeans grow better, but it can also hurt them if there’s too much, showing a weird effect called plant hormesis.
  • Researchers studied how different amounts of Ni (ranging from none to 9.0 mg) changed what minerals were in soybeans, like increasing good nutrients and reducing harmful ones.
  • The best results were seen at lower amounts of Ni, while too much nickel caused plants to grow worse, showing that it’s important to use the right amount for healthy soybeans.

Sensitive electrochemical detection of methimazole based on a unique copper and exfoliated graphene oxide nanocomposite.

Chemosphere

October 2024

Electrochemical Technology Centre, Department of Chemistry, University of Guelph, 50 Stone Rd E, Guelph, Ontario, N1G,2W1 Canada. Electronic address:

Herein, we report the creation of a novel sensitive electrochemical sensing platform based on a copper and exfoliated graphene oxide (Cu-eGO) nanocomposite using a facile synthesis technique, which simultaneously removes the sodium ions that result from the exfoliation process to generate eGO from graphite. This novel Cu-eGO nanocomposite was characterized via SEM, EDX, Raman and XPS. The Cu-eGO/GCE exhibited much greater activity for the electrochemical oxidation of methimazole than the eGO/GCE or bare GCE.
