Summary: Ni-Co LDHs were synthesized with different Ni/Co molar ratios and used as cathode materials for Ni-MH batteries. Compared with Ni(OH)2, Ni-Co LDHs electrodes exhibited higher discharge capacity and cycling stability. The NC 2 electrode with a Ni/Co molar ratio of 4:1 showed the highest discharge capacity and capacity retention after 200 cycles. The unique morphology and enlarged interlayer spacing of Ni-Co LDHs promoted ion transmission and charge transfer, while their structural stability and synergies with Co-Co LDHs were important for electrochemical performances.

Summary: Due to the complexity and cost of traditional methods for detecting heavy metal pollution in water, there is a need for rapid and simple methods. In this study, a nanobiosensor based on molybdenum disulphide (MoS2) nanosheets and fluorophore labeled oligonucleotides was proposed for detecting Hg2+ or Ag+ ions in water using fluorescence spectroscopy. The sensor works by forming stable double-stranded DNA (dsDNA) structures through the mismatching of single-stranded DNA (ssDNA) rich in thymine (T) or cytosine (C) with Hg2+ or Ag+. The sensor showed high sensitivity and selectivity, with minimum detection limits of 6.8 nM and 8.9 nM for Hg2+ and Ag+ ions, respectively.
