Abstract:

Electrochemical capacitors operating in an aqueous electrolyte solution have become ever-more popular in recent years, mainly because they are cheap and ecofriendly. Additionally, aqueous electrolytes have a higher ionic conductivity than organic electrolytes and ionic liquids. These materials can exist in the form of a liquid or a solid (hydrogel). The latter form is a very promising alternative to liquid electrolytes because it is solid, which prevents electrolyte leakage. In our work, hydrogel polymer electrolytes (HPEs) were obtained via photopolymerization of a mixture of acrylic oligomer

The performance of porous carbon (PC)-based supercapacitor especially the energy density for the most part is dependent on its electrolytic system. Sodium sulfate (Na2SO4) is the most studied neutral aqueous electrolyte system studied so far for the PC-based electric double-layer capacitors (EDLC). But the theoretical value for the working potential of Na2SO4 is limited to only 1.23 V, and hence it limits the energy density of the storage system.

This study presents the fabrication of a samarium-doped Ti/Sb-SnO2/PbO2 electrode and investigates its applications in polluted water treatment and energy conversion. Physicochemical properties were characterized by scanning electron microscopy with energy-dispersive X-ray spectroscopy, X-ray powder diffraction analysis, and Raman spectroscopy. The Ti/Sb-SnO2/Sm-PbO2 electrode showed 2.5 times higher oxygen evolution potential activity than the Ti/Sb-SnO2/PbO2 electrode. Density Functional Theory was used to conduct first-principles calculations, and the obtained results indicated that Sm dopi

The flotation separation (FS) of both scheelite and calcite minerals with similar physicochemical properties remains challenging, since the Ca active sites exist on their surfaces. The present work investigated the effects of different addition points of MnCl2 on the FS of scheelite and calcite by micro-flotation tests, zeta potential measurements, UV-Vis spectrophotometer measurements, infrared spectrum analysis, and X-ray photoelectron spectroscopy (XPS) tests, and the mechanism of separation is elucidated. Interestingly, the recovery of scheelite was 91.33% and that of calcite was 8.49% whe

Abstract Starch can be produced from many plant varieties and through various processing methods. Breadnut (Artocarpus camansi) is a plant variety containing seeds that are rich in carbohydrates to produce starch. However, it has not been widely used and converted into useful products because it is still traditionally considered waste. Starch can be produced physically, chemically, and enzymatically. In this study, the starch extraction from breadnut seeds was conducted using a chemical method, namely immersion into sodium metabisulfite (Na2S2O5) at concentrations of 600, 800, and 1000 ppm. Ch

Tannins from Myrcia splendens from the Amazon rainforest were used for the first time in the formulation of a urea-tannin-formaldehyde (UTF) resin. The objective was to evaluate the effect of different tannin proportions on the glue line performance in Pinus sp. woods, glued with UTF adhesive. The tannins were extracted in a water bath, using 1500 mL of water and 100g of dry bark (liquor/bark 15:1), with addition of 3% Na2SO3, at a temperature of 70 °C for three hours. The adhesives formulations were based on the gradual replacement of mass of the urea-formaldehyde (UF) adhesive by tannin powd
