Sulfur cathodes in lithium-sulfur batteries (LSBs) have received a boost in electrochemical performance through developing various sulfur hosts. However, it remains great challenges in achieving fast electron and ion conduction while accommodating the dramatic volume change and suppressing sever...

Molecular surrounding environment is one of the important factors that can modify nonlinear properties of materials. For precise investigation, in this paper, single beam Z-scan technique was used for measuring the third order nonlinear responses of Basic Blue 55 molecules in different solvent m...

Recently, Zeolitic imidazolate framework-8 (ZIF-8) has drawn considerable attention in preparing mixed matrix membranes (MMMs) because of high specific surface area and unique pore structure. However, the structure degradation of ZIF-8 was found in the preparation process of a polyimide (PI)-bas...

In this work, zeolitic imidazolate framework-8 (ZIF-8) was successfully synthesized by a facile reaction via water and alcohol solvents at room temperature. Additionally, Ag/[email protected] was successfully fabricated by doping Ag/AgCl onto ZIF-8, which were characterized by powder X-ray diffr...

The role of water in the TiO2-based photocatalytic phenomenon is not yet fully understood. The photocatalysis of methylene blue dissolved in propylene carbonate and different concentrations of water was studied. It was observed that the photocatalytic activity of TiO2 (P25 from Evonik) peaks whe...

Inefficient blue emission is one of the key bottlenecks limiting the development of solution processable displays and white light sources, which is essentially governed by the film quality of the solution-processed emission layer (EML). Here, we use an efficient blue thermally activated delayed ...

The solubility of methylene blue in methanol, ethanol, 2-propanol, acetone, ethyl acetate, and water was measured at 303.15 K and 0.1 MPa. The solubility of methylene blue in ethyl acetate was very low while the solubility in methanol and 2-propanol was very high and not precisely measurable. In...

This investigation elucidated the decolorization of C.I. Reactive Red 2 (RR2) in US/TiO2, UV/TiO2 and UV/US/TiO2 systems and evaluated the effect of ultrasound (US) irradiation in photocatalysis. The effects of RR2 concentration, temperature and the addition of NaCl, Na2S2O8 and radical scavenge...

An analysis is provided of the various concepts and theories that have been proposed to account for the manner by which added NaCl or Na2SO4 promotes the uptake of direct dyes on cellulosic fibres. Although conventional approaches to describe the mechanism by which direct dye adsorption occurs e...

This study discusses the effects of ultrasound (US) irradiation on the decolorization of C.I. Reactive Red 198 (RR198) in UV/ZnO system. The influences of ZnO dosage, pH and the addition of NaCl or a radical scavenger were evaluated. The decolorization rate of RR198 increased with the ZnO dosage...

The present study aims at developing Grey triggerfish skin gelatin films containing phenolic extracts from blood orange (Citrus sinensis) peel, as an alternative for the existing synthetic packaging films. The effect of drying pretreatment on the phenolic compounds’ profile and antioxidant and ...

To examine the effect of sugar reduction on the sensory perception of sweetened beverages, an orange juice soft drink model flavoured with seven characteristic compounds (hexanal, decanal, linalool, ethyl butanoate, α-pinene, β-myrcene and (Z)-3-hexen-1-ol) was developed. Five samples were pre...

Mesoporous δ-Bi2O3 samples with high surface area and small crystallite sizes were prepared by using different SBA-15 silicas as hard templates. The latter were synthesized hydrothermally using tetraethylorthosilicate (TEOS), sodium metasilicate (SMS), and water glass (WG) as silica sources. Th...

In testing a series of bismuth oxybromo-iodide (BiOBrxI1−x; 0 ≤ x ≤ 1) solid solutions, BiOBr0.9I0.1, due to its superior charge-carriers separation, exhibited the best performance in the visible-light-driven photocatalytic degradation of pharmaceutical and personal care products (PPCPs). Subs...

Solution-processed Methylammonium iodo bismuthate (MBI) perovskite solar cell is fabricated by spray technique with changed applied voltages from 0 to 1000 V during the deposition of MBI thin film. The morphology and surface roughness of MBI films are influenced significantly by the electric fie...

To improve the uptake effect of iodide anions from aqueous solution, mesoporous Fe-based MOFs ([email protected]) were prepared by mixing Bi(III) and MIL-101(Fe) in Teflon-lined autoclave using solvothermal synthetic method.
