Drilling performance analysis of a polycrystalline diamond compact bit via finite element and experimental investigations
(Elsevier, 20 August 2024)The significance of improving the drilling productivity and reducing the cost and non-productive time of drilling process, substantially relies on the efficiency of drilling performance. This paper provides a comprehensive ... -
Implementation of circular economy in a developing economy’s mining industry using institutional theory: The case of Namibia
(Elsevier, 13 August 2024)Despite the global focus on sustainability, transitioning from linear to circular production systems is slow in the mining sector of most developing economies like Namibia. However, mining plays a crucial role in supporting ... -
New insights into coarse particle lifting performance of a hydraulic ejector with an ultra-large area ratio
(Elsevier, 14 August 2024)Hydraulic ejectors with ultra-large area ratios (HE-ULAR) have potential applications as particle lifting equipment in fluidized coal mining. This study analyzed the effects of area and pressure ratios on the coarse ... -
A nonenzymatic reduced graphene oxide-based nanosensor for parathion.
(Beilstein-Institut, 28 July 2022)Organophosphate-based pesticides (e.g., parathion (PT)) have toxic effects on human health through their residues. Therefore, cost-effective and rapid detection strategies need to be developed to ensure the consuming food ... -
Performance analysis of multiple energy-storage devices used in electric vehicles
(MDPI, 8 August 2024)Considering environmental concerns, electric vehicles (EVs) are gaining popularity over conventional internal combustion (IC) engine-based vehicles. Hybrid energy-storage systems (HESSs), comprising a combination of batteries ...
