EFFICIENCY OF MATERIAL REMOVAL AND MACHINING IN CUTTING

open access: yesCutting & Tools in Technological System, 2020
Among the methods and parameters used for analyzing the productivity of machining procedures, this paper deals with an analysis based on the efficiency (material volume removed in unit time) of material removal. The paper focuses on how this specific indicator, the material removal rate (MRR), changes when different machining procedures and production ...

Enhanced arsenic removal using lateritic bauxite modified by heating and blending

open access: yesWater Science and Technology, 2022
The use of bauxite to remove arsenic from wastewater has been confirmed to be effective, but its removal efficiency in literature is not up to 90%, hence the need to devise a more effective method to remove arsenic from wastewater. In this study, a novel

Pb Removal Efficiency by Calcium Carbonates: Biogenic versus Abiogenic Materials

open access: yesCrystal Growth & Design, 2023
The sorption of heavy metals on mineral surfaces plays a key role in controlling the fate and bioavailability of harmful elements through dissolution-precipitation reactions. Here, we investigate the efficiency of Pb removal from highly contaminated waters by two calcium carbonate hard tissues, scallop shells (up to 99.9 mol %; -biocalcite) and ...

An efficient recyclable magnetic material for the selective removal of organic pollutants [PDF]

open access: yesBeilstein Journal of Nanotechnology, 2016
Wastewater cleaning strategies based on the adsorption of materials are being increasingly considered, but the wide variety of organic pollutants at low concentrations still makes their removal a challenge. The hybrid material proposed here consists of a zwitterionic polyethylenimine polymer coating a magnetic core.
