  • Copper Micro-Flowers for Electrocatalytic Sensing of Nitrate Ions in Water

    The progressive increase in nitrate’s (NO) presence in surface and groundwater enhances environmental and human health risks. The aim of this work is the fabrication and characterization of sensitive, real-time, low-cost, and portable amperometric sensors for low NO concentration detection in water. Copper (Cu) micro-flowers were electrodeposited on top of carbon screen-printed electrodes (SPCEs) via…

  • Effect of Data-Processing Methods on Acceleration Summary Metrics of GNSS Devices in Elite Australian Football

    This study aimed to measure the differences in commonly used summary acceleration metrics during elite Australian football games under three different data processing protocols (raw, custom-processed, manufacturer-processed). Estimates of distance, speed and acceleration were collected with a 10-Hz GNSS tracking technology device from fourteen matches of 38 elite Australian football players from one team. Raw…
