Article Synopsis
  • Scientists are trying to create better materials to help save energy and the environment by using non-precious metals instead of expensive ones for a process called the oxygen evolution reaction (OER).
  • They developed a new method to make a special material called iron-modulated NiS, which is built on nickel foam and helps improve the efficiency of this reaction.
  • Tests showed that this new material works really well, needing less energy to create a strong electrical current, and it stays stable during long use, making it a good option for future energy solutions.

Electrochemical water splitting is a promising approach to produce hydrogen gas, but sluggish four-electron transfer of the oxygen evolution reaction (OER) severely limits the overall energy conversion efficiency of water splitting. Herein, as an excellent OER electrocatalyst, a technique of synthesizing Fe doped CoNiSe nanosheet (Fe-CoNiSe) whole series using CoFe prussian blue analog produced by Co-ZIF-L reaction as a template is proposed here. The introduction of iron ions promotes the redistribution of the cobalt-nickel charge density, which enhances the OER kinetics.

A novel LUX (Light Upon eXtension) primer-based real-time PCR assay was developed and evaluated in this study, which was designed to provide a cost-effective, specific and highly sensitive method for viral load determination of hepatitis B virus (HBV). The assay employed an effective and rapid nucleic acid extraction system based on magnetic beads. To evaluate its efficacy, this new viral DNA preparation method was compared with QIAamp Blood Mini Kit and the results showed a good correlation (r=0.
