Hydrogen evolution at Ni foam electrodes and Ni-Sn coated Ni foam electrodes
(Elsevier B.V., 2023)
The hydrogen evolution reaction (HER) was investigated in 1.0 M KOH at 25 °C at Ni foams with different pore sizes (450–1200 µm), and at the Ni-Sn/Ni foam electrodes, where Ni-Sn alloys were electrodeposited from the ...
Advancing PHBV Biomedical Potential with the Incorporation of Bacterial Biopigment Prodigiosin
(Switzerland : Multidisciplinary Digital Publishing Institute (MDPI), 2023)
The quest for sustainable biomaterials with excellent biocompatibility and tailorableproperties has put polyhydroxyalkanoates (PHAs) into the research spotlight. However, high productioncosts and the lack of bioactivity ...
Magneto-Mechanical and Thermal Properties of Nd-Fe-B-Epoxy-Bonded Composite Materials
(MDPI, 2023)
Polymer-bonded magnets are a class of composite material that combines the magnetic properties of metal particles and the molding possibility of a polymeric matrix. This class of materials has shown huge potential for ...
Effects of liquid surface tension on gas capillaries and capillary forces at superamphiphobic surfaces
(NLM (Medline), 2023)
The formation of a bridging gas capillary between superhydrophobic surfaces in water gives rise to strongly attractive interactions ranging up to several micrometers on separation. However, most liquids used in materials ...
Non-Destructive Examination for Cavitation Resistance of Talc-Based Refractories with Different Zeolite Types Intended for Protective Coatings
(MDPI, 2023)
In many industrial processes that include fluid flow, cavitation erosion of different engineeringstructures (pumps, turbines, water levels, valves, etc.) during their operation is expected. Metallic,ceramic, and composite ...
Recovering the Soybean Hulls after Peroxidase Extraction and Their Application as Adsorbent for Metal Ions and Dyes
(Hindawi Limited, 2023)
This study is aimed at extending the soybean hulls' lifetime by their utilization as an adsorbent for metal ions (Cd2+ and Cu2+) and dyes (Reactive Yellow 39 (RY 39) and Acid Blue 225 (AB 225)). ATR-FTIR spectroscopy, ...
A closed cycle of sustainable development: Effective removal and desorption of lead and dyes using an oxidized cellulose membrane
(Elsevier B.V., 2023)
Oxidized cotton linters, TOCell, were used as an adsorbent or derived membrane there from by linters
cross-linking with citric acid. The adsorption/desorption study of Pb2+, methylene blue (MB), and crystal
violet (CV) ...
From Aloe vera Leaf Waste to the Extracts with Biological Potential: Optimization of the Extractions, Physicochemical Characterization, and Biological Activities
(MDPI, 2023)
In the study, the optimization of the extraction from Aloe vera leaf waste was performed via varying solid-to-solvent ratio, solvent type, extraction time, and technique (maceration, heat-, ultrasound-, and microwave-assisted ...
Influence of Ultrasonic and Chemical Pretreatments on Quality Attributes of Dried Pepper (Capsicum annuum)
(MDPI, 2023)
This study investigates the effects of ultrasound, in combination with chemical pretreatments, on the quality attributes (total phenolic and carotenoid content, antioxidant activity (2,2-Diphenyl-1-picrylhydrazyl assay ...
Effect of Shielding Gas Arc Welding Process on Cavitation Resistance of Welded Joints of AlMg4.5Mn Alloy
(MDPI, 2023)
The effect of the shielding gas arc welding process on the cavitation resistance of the three-component aluminum alloy AlMg4.5Mn and its welded joints was investigated. Welding was performed using the GTAW and GMAW processes ...
