The commercial azo dye C.I. Reactive Orange 4 in its reactive and hydrolysed forms can be efficiently photodegraded, using commercial samples of TiO2 as a photocatalyst. With UV light, aqueous solutions containing only dye and no dyebath additives are decolourised slightly more rapidly with Ried...

This paper reports the results of a study on the surface fluorinated titanium dioxide Wackherr’s “Oxyde de titane standard”, which shows very interesting photocatalytic activity. Characterization of FTiO2 Wackherr reveals that FTiO2 has smaller size compared to TiO2 Wackherr. The effect of fl...

Photocatalytic activity of surface fluorinated TiO2-P25 (F-TiO2-P25) in the degradation of a chlorotriazine azo dye Reactive Orange 4 (RO 4) under ambient conditions was investigated in this study. Characterization of F-TiO2-P25 reveals that the catalyst has a strong absorption in the UV range a...

In the present work, degradation of reactive orange 4 dye (RO4) has been investigated using hydrodynamic cavitation (HC) and in combination with other AOP’s. In the hybrid techniques, combination of hydrodynamic cavitation and other oxidizing agents such as H2O2 and ozone have been used to get ...

The catalytic ozonation using mesoporous SBA-15 supported copper catalyst (Cu/SBA-15) was employed for the degradation of reactive orange 4 (RO4) azo dye in aqueous solution. The catalyst was synthesized and characterized using BET, SEM, TEM and EDX techniques. The characteristic results reveale...

The purpose of this article is to present a qualitative model that allows researchers and practitioners to analyze activities that can contribute to eco-efficiency in the context of Green Supply Chain Management. A literature review identified 21 green practices, organized in four groups using c...

With the increase in demand for bio-based coatings with lower volatile organic compound (VOC) emissions, methacrylated cardanol (MACO) and triethoxysilane-functionalized cardanol (TSCO) have been investigated as bio-based reactive diluents for formulating alkyd coatings as a substitute for volat...

This study investigates green tea extract synthesized conditions impacting on the reactivity of iron nanoparticles (Fe NPs) used for the degradation of malachite green (MG), including the volume ratio of Fe2+ and tea extract, the solution pH and temperature. Results indicated that the reactivity...

The nucleus is in charge of the metabolism and heredity of the cell, and genetic mutations are closely related with tumour multidrug resistance (MDR). Indocyanine green (ICG), the FDA-approved photosensitizer, is widely used for tumour photodynamic therapy (PDT) and photothermal therapy (PTT). F...

The in vivo mechanism of tea polyphenol-mediated prevention of many chronic diseases is still largely unknown. Studies have shown that accumulation of toxic reactive cellular metabolites, such as ammonia and reactive carbonyl species (RCS), is one of the causing factors to the development of man...

This paper describes the reduction of p-nitrophenol by green rusts (GRs) interlayered with common inorganic anions (Cl−, SO42− and CO32−). Modifying of GRs with zero-valent Cu nanoparticles (Cu0 NPs) can greatly enhance the reductive reactivity of GRs via the formation of a galvanic couple betwe...

Melatonin, an important and conserved indoleamine compound, is involved in many plant physiological functions. Postharvest diseases caused by fungal pathogens lead to huge economic losses worldwide, but nothing is currently known about the role of melatonin in fruit resistance to postharvest dis...

The effect of green bodies’ mesostructure on the porosity, optical properties and laser performance of reactive sintered Y3Al5O12:Nd3+ transparent ceramics was studied. Only minor changes in microstructure were revealed for green bodies without annealing and those annealed at 600, 800, 1000 °C...

In the present work, we investigate the degradation of recalcitrant industrial textile dye (Reactive green 12) in aqueous solution by TiO2 impregnated polyester at room temperature. The TiO2 loading on polyester was optimized using different polyester pretreatments (plasma surface activation and...

In this study, CuO/Cu(OH)2 (denoted as CuONs) nanostructures were synthesized relying to a cheap and rapid chemical co-precipitation method using copper sulfate and liquid ammonia as precursors. Results obtained from X-ray diffraction, and field emission scanning electron microscopy analysis rev...

A preventive approach to reduce the environmental burden associated with textile processing was demonstrated by creating a fully recyclable reactive dyeing process for cotton. Reactive dyeing is the most commonly used coloration method for cotton, yet it generates the most problematic effluents ...

In this study, we report a simple method to synthesize a novel green nanocatalyst using titanium dioxide, graphene and Citrus sinensis peel extract using a low-power CO2 laser fabrication.
