Sensitivity equivalent to 17.4 μA mM -1 BOD could be achieved. An application of the modified BDD for a biochemical oxygen demand (BOD) sensor using Rhodotorula mucilaginosa UICC Y-181 as the biosensing agent was also demonstrated with glucose solutions as the solution model. Good linearity in a concentration range from 2 to 9 ppm could be achieved with a sensitivity of 0.0138 mA ppm -1 and limit detection of 1.98 ppm. A stronger Q2 performance across the portfolio has kept Barrick on course to achieve its annual gold and copper production guidance while continuing to. Moreover, around two times higher current responses of oxygen reduction reaction were observed at BDD. It was also found that the use of allylamine as the bridge can attach more gold than copper nanoparticles. Obtaining core-shell metallic nanofoams such as copper and nickel appears to be possible through electrospinning, thermal treatments, and subsequent electroplating, but controlling the thickness of the shell of nickel over the copper ligaments of the nanofoam requires further experimentation and can be done on different types of metals. Past work with this material has shown strong biological efficacy for protecting solid wood and tree health ( e.g., Qi et al. Comparison among the BDD modified with and individual gold nanoparticles showed that nanoparticles created around 3 times higher gold coverage on the BDD surface than normal gold nanoparticles. Copper/carbon core/shell nanoparticles (CCCSNs) are a newly available type of industrial material that is prepared using a proprietary manufacturing technology (Lian and Wu 2012). These nanoparticles were then attached to the BDD surface by using allylamine as the bridge. Nanorod particles with a diameter size of around 10 nm and a length of around 20 nm were successfully synthesized. TNTAs are fabricated using a cheap and effective electrochemical anodization method, and high-density copper nanowires are synthesized via excess-electrodeposition with a novel peeling-off strategy. Bimetallic copper-gold nanoparticles were synthesized and utilised to modify boron-doped diamond (BDD) electrodes. In this paper, we report an electrochemical method to produce a novel memristor based on copper nanowire-titanium dioxide nanotube arrays (TNTAs), a core-shell composite material.
