Iridium oxohydroxide thin coatings have been prepared by a dynamic oxidation electrodeposition method from complex oxalate solutions that induce template effects in the final coating at nanoscale. The preparation induces formation of with reproducible stoichiometry and sponge-like quasiamorphous open structure, high ionic mobility, significant behavior as compared other reported iridium oxides derived X-ray diffraction, XPS, TGA. Reproducible mixed valence states are also observed local...
The effects of adding zero-valent iron nanoparticles (nZVI) on the physicochemical, biological and biochemical responses a semi-continuous anaerobic digestion sewage sludge have been assessed. Two sets consecutive experiments 103 116 days, respectively, were carried out in triplicate. nZVI magnetically retained reactors, effect punctual doses (from 0.27 to 4.33 g L−1) over time was studied. Among different parameters monitored, only methane content biogas significantly higher when added....
Solid-state fermentation (SSF) is part of the pathway to consolidate waste as a relevant alternative for valorization organic waste. The objective SSF produce one or several bioproducts added value from solid substrates. can use wide variety substrates thus, it an excellent candidate in framework circular bioeconomy change status feedstock. development was boosted previous decade by scientific efforts devoted production hydrolytic enzymes. Nowadays, has expanded other valuable products:...
The removal of heavy metals from industrial wastewater is nowadays one the most interesting challenges in water remediation using adsorbent nanomaterials. present study presents a novel (Fe3O4@[email protected]2) nanocomposite (NC), by functionalization carboxymethyl cellulose (CMC) cross-linked to magnetic chitosan nanoparticles (Fe3O4@CS NPs) with aminopropyl triethoxysilane layer (APTES), and evaluate its performance toward lead (II) wastewater. synthesized NCs were characterized several...
The effect of magnetite nanoparticles and nanocomposites (magnetite impregnated into graphene oxide) supplement on the recovery overloaded laboratory batch anaerobic reactors was assessed using two types starting inoculum: granular sludge (GS) flocculent (FS). Both nanomaterials recovered methane production at a dose 0.27 g/L within 40 days in GS. Four doses from 0.075 to 1 process FS systems between 30 50 relaying dose. presence helped reverse volatile fatty acids inhibition enabled...
Abstract The valorization of biogas as a renewable energy source faces major obstacle regarding its purification. Siloxane is one the impurities that cause problems such damages to equipment combustion engines, turbines, and boilers used for conversion heat electricity. In this review, adsorption siloxane removal widely discussed, with two specific approaches: adsorbents sensitivity water regeneration, essential points industrial application. Thus, determining factors in capacity,...
In the present work, effect of pure lactonic sophorolipids (SL) on anaerobic digestion biowaste was investigated. For this purpose, crude SL were produced from organic waste (a mixture molasses and winterization oil cake) through solid-state fermentation (SSF) in a 22L pilot-scale aerobic bioreactor using yeast Starmerella bombicola as SL-producing microorganism. The material extracted SSF exhaust solid contained several forms it purified High-Performance Liquid Chromatography (HPLC)...
Nowadays, there is a growing awareness of the great environmental impact caused by enormous amounts carbon dioxide emitted. Several alternatives exist to solve this problem, and one them hydrogenation into methanol using nanomaterials as catalysts. The aim alternative produce value-added chemical, such methanol, which cheaply available feedstock. development improved materials for conversion reaction deeper study existing ones are important obtaining higher efficiencies in terms yield,...
Composting has demonstrated to be an effective and sustainable technology valorise organic waste in the framework of circular economy, especially for biowaste. can performed various technological options, from full-scale plants community or even individual composters. However, there is scarce scientific information about potential impact composting referred gaseous emissions. This work examines emissions methane nitrous oxide as main GHG, ammonia, VOC odours different active sites placed...
Innovative neurostimulation therapies require improved electrode materials, such as poly(3,4-ethylenedioxythiophene) (PEDOT) polymers or IrOx mixed ionic-electronic conductors and better understanding of how their electrochemistry influences nerve growth. Amphibian neurons growing on transparent films electronic (metal) electronic-ionic (polymers semiconducting oxides) are monitored. Materials not connected directly to the power supply, but a dipole is created wirelessly within them by...
Abstract Cu/ZnO/CeO 2 nanocomposite was supported on metal organic framework (MOF-5) to enhance active sites dispersion and control the nanoparticles agglomeration during synthesis through strong metal-support interactions. The incorporation of MOF-5 alleviated obstacle facing commercial ternary Cu/ZnO/Al O 3 regarding low surface area due agglomeration. In addition, @MOF-5 gave higher methanol selectivity than catalyst which can be accounted for by interfacial generated between Cu/ZnO...
The increasing emission of carbon dioxide into the atmosphere has urged scientific community to investigate alternatives alleviate such emissions, being that they are principal contributor greenhouse gas effect.

Nanoscale zero-valent iron (nZVI) has the potential to degrade a diversity of chlorinated compounds, and it is widely used for remediation contaminated groundwaters. However, some frequently detected contaminants such as dichloromethane (DCM) 1,2-dichloroethane (1,2-DCA) have shown nearly no reactivity with nZVI. Here, we tested feasibility combining anaerobic dechlorinating bacteria, Dehalobacterium Dehalogenimonas, nZVI treatment train detoxify methanes (i.e., chloroform-CF- DCM), 1,2-DCA....
