Building insulators reducing the natural gas required for interior heating or heating load reduction, have a positive impact on energy saving. Paints containing nano-silica aerogel can be applied as façade coatings and building insulators. In this study, the heating load was assessed for a building in a Mediterranean climate. Acrylic paint containing nano-silica aerogel was […]
Fe-doped Bi2WO6/CeO2 nanocomposite materials were prepared by co-precipitation and hydrothermal methods. The physicochemical properties and photocatalytic activities of Bi2WO6/CeO2 nanocomposites after doping with Fe3+ ions were systematically investigated. The 0.2Fe-doped Bi2WO6/CeO2 nanocomposites exhibited the optimal photocatalytic activity in the degradation of rhodamine B (RhB), reaching to 62% degradation after 120 min irradiation, which was 10.3 and […]
The commercially available bleach activator, N,N,N′,N′-tetraacetylethylenediamine (TAED), has been widely used in laundry detergents to enable efficient low-temperature bleaching. However, the competitive hydrolysis of TAED limits its use in liquid detergents. Herein we report the synthesis of two TAED derivatives, N,N,N′,N′-tetracetylpropylene-1,2-diamine (TA(Me)ED) and N,N,N′-triacetylpropylene-1,2-diamine (TriA(Me)ED), through the acetylation of propylene-1,2-diamine. The hydrolytic and perhydrolytic activity […]
The standard method (ISO 4264) for determining the cetane index of hydrogenated gas oil is time-consuming and expensive for routine laboratory tests. Conversely, near infrared (NIR) and Raman spectroscopies are high-speed and cost-effective techniques. In this study, these tools were used to create two models for the determination of the hydrogenated gas oil cetane index. […]
The oxidation of sulfide-based ores is industrially relevant as it facilitates the extraction of valuable metals and eliminates undesired elements from an ore. Even though oxidation can be done thermally (pyrometallurgy), solution-based (hydrometallurgical) methods are currently sought as they represent a more sustainable option. Here, the leaching of a sulfide ore (32% Fe, 2% Cu) […]
