The production of fertilizers has been evolving steadily in the last 300 years. It involves a high number commodities and reagents that share large portion costs emissions greenhouse gases (GHGs), particularly carbon dioxide (CO2). Phosphorus, nitrogen, potassium components represent more than 200 million tonnes annually. Given most fertilizer process is dependent on fossil fuels as fuel feedstock, amount CO2 generated at least 3 per tonne fertilizer. introduction, future, less intensive...
The coronavirus pandemic, which appeared in Wuhan, China, December 2019, rapidly spread all over the world only a few weeks. Faster testing techniques requiring less resources are key managing either to enable larger scale or even just provide developing countries with limited resources, particularly Africa, means perform tests manage crisis. Here, we report an unprecedented, rapid, reagent-free and easy-to-use screening spectroscopic method for detection of SARS-CoV-2 on RNA extracts. This...
Abstract Intense visible nano-emitters are key objects for many technologies such as single photon source, bio-labels or energy convertors. Chalcogenide nanocrystals have ruled this domain several decades. However, there is a demand cheaper and less toxic materials. In scheme, ZnO nanoparticles appeared potential candidates. At the nanoscale, they exhibit crystalline defects which can generate intense emission. even though photoluminescence quantum yields high 60% been reported, it still...
Abstract In this work, five phenanthroline derivatives substituted with different methyl groups have been selected to synthesize β‐diketonate‐based europium complexes check the influence of substitutions on degradation effect those in poly(methyl methacrylate) (PMMA) films. The photophysical properties Eu(III) complexes, including absorbance, excitation, and emission carefully investigated solution, solid‐state, doped PMMA film. all these states, exhibit an impressive red at 614 nm a high...
This study deals with the immobilization of mixtures two semiconductor oxides Cuo and TiO 2 on fi brous palygorskite clay minerai in order to evaluate their photocatalytic activity for removing Orange G dye as model pollutant from aqueous solutions.The elaboration CuO-TiO:!Palygorskite nanocomposites was carried out by impregnation Cu 2+ before hand synthesized sup ported (Pal) followed air annealing 5 h at 550 •c.ln composite materials, different Cuo+ molar ratios were used obtain a content...
Composed of two europium complexes doped in polyvinyl butyral as the host material, a novel photoluminescent ink has been formulated by synthesizing Eu(FAC)3Phen red luminescent down-shifting emitter and employing SrAl2O4:Eu, Dy long persistent green phosphor. Both emitters are incorporated to design with binary emission under single UV excitation wavelength, where light is emitted when exposed 325 nm, subsequently becoming upon being switched off. The concept presented here unequivocally...
Mesoporous silicate materials (MSMs) exhibit tremendous intrinsic characteristics suitable for diverse adsorption-based processes. However, the challenges brought on by lack of sustainable production methods pose obstacles to large-scale synthesis...
This study reports the successful synthesis of supported TiO2_Palygorskite nanocomposites by a one-pot dry mechanochemical route. Indeed, elaboration procedure involved an in-situ reaction between accessories carbonates present in raw fibrous palygorskite clay and titanyl sulfate (TiOSO4) precursor under variable grinding conditions, essentially ball/solid matter mass ratio rotation velocity. yielded after air annealing at 600%C for 1 h to immobilization anatase TiO2 nanoparticles (≈8 nm...
