For applications of aluminum where the smoothness or reflectivity of the aluminum matters, electropolishing is necessary to polish the aluminum surface sufficiently. This electropolishing is traditionally done with hazardous solutions in non-ideal conditions, such as low-temperature perchloric acid-ethanol mixtures. Here, we describe electropolishing of aluminum using a deep eutectic system composed of propylene glycol and choline chloride, with polishing accomplished at room temperature and using an inexpensive apparatus. This polishing was performed using both 99.5 and 99.99% pure aluminum, and scanning electron microscopy images show substantial improvement with both purities of aluminum. In addition, reflectivity measurements show significant improvement over sanding of aluminum. This method provides a simple, green method for electropolishing aluminum that can be used in any research where careful polishing of aluminum is necessary.

Different flavone extracts from apple peel and aldehydes from grape stems were investigated as restraints of the anodic aluminum dissolution procedure in 60% HPO:40% HSO. The potential-limiting current correlation for Al anode was assessed and associated with regularly improving apple peel and grape stems extract concentration (100 to 1000 ppm range). The limiting current reduces whereas retardation effectiveness (%) increases as the concentrations of apple peel and grape stems extract rise.

The conditions applied during the electrochemical polishing of aluminum were found to be important parameters for the successive formation of nanoporous alumina films. First, a high-purity Al foil was electrochemically polished in an aqueous solution containing CHOH and HClO at various sets of conditions, such as applied potential (5-35 V), temperature (0-20 °C), and process duration (10-180 s). Extensive studies of the topography of Al after polishing by scanning electron microscopy and atomic force microscopy allow verification of the correlations between conditions applied during the substrate pretreatment and dimensions of the nanopatterns generated on the metal surface.

The laser ablation process has been presented as a state-of-the-art and robust method for eliminating surface layers of metallic bulk materials on the micro/nanoscale with considerable accuracy and speed. These capabilities make it an ideal instrument for the primary step of metallic bulk sample preparation for transmission electron microscopy (TEM) analysis with minimal damage to the crystal structure of the sample. This work prepared a pure aluminum plate by fiber laser scanning immersed in a 5 % perchloric acid and 95 % ethanol (by volume) solution.

Climate change has worsened droughts and floods, and created conditions more likely to lead to pathogen contamination of surface water and groundwater. Thus, there is a growing need to disinfect livestock water. Ultraviolet (UV) irradiation is widely accepted as an appropriate method for disinfecting livestock water, as it does not produce hazardous chemical compounds and kills pathogens.
