Article Abstract
This study reported one-pot hydrothermal synthesis of 3D garland BiOI, spherical ZnO, and carbon nanofibers (CNFs) onto Ni foam substrate with improved supercapacitor performance and enhanced electrochemical properties. The synthesized nanocomposites exhibited high specific capacitance (SC) of 1073 g at a current density of 1 A/g and excellent cycling stability with 88.6% retention of original capacity after 5000 cycles in 2M KOH aqueous solution. The findings highlight the potential of 3D materials for use as electrode materials in advanced supercapacitor applications due to their high energy storage capabilities.

Lead (Pb) is a highly toxic heavy metal that causes significant health hazards and environmental damage. Thus, the detection and removal of Pb ions in freshwater sources are imperative for safeguarding public health and the environment. Moreover, the transformation of single resources into multiple high-value products is vital for achieving sustainable development goals (SDGs).

A polyethyleneimine (PEI)-assisted simple and efficient one-pot hydrothermal reduction method is reported to prepare high-quality gold nanodendrites (AuNDs) on a carbon nanotube (CNT) sheet. We observed that the prepared AuNDs have a well-defined backbone-multiple branching structure. With the systematical investigation of the growth mechanism, it was found that the bromide (Br) ion concentration has an essential effect on the formation of AuNDs.

Epinephrine (Ep) is an important neurotransmitter, which plays an important role in the nervous system and glycogen metabolism of living organisms. Hence, a novel NCQDs/FeCoFe-PBA composite with FeCoFe-Prussian blue analogues (PBA) as the core and nitrogen-doped carbon quantum dots (NCQDs) as the shell was constructed by a one-pot hydrothermal method, and it was used for the efficient detection of Ep. As a good electroactive material, NCQDs in the composite not only improved the weak conductivity of FeCoFe-PBA, but also limited the self-aggregation of FeCoFe-PBA, and formed a uniform shell on FeCoFe-PBA.

For separation of deoxyribonucleic acid (DNA), positively charged amino-modified magnetic nanoparticles (MN) can effectively adsorb negatively charged DNA through electrostatic interaction. However, the reported preparation of amino-modified MN is usually tedious and time-consuming. Therefore, a simple synthesis method of amino-modified MN is necessary for DNA extraction.
