This review provides a state-of-the-art summary of distributed zeolite technology, as well identifying strategies to further promote the absorption these materials in various areas study. Zeolites are that can be synthesized or found natural rock deposits with basic composition consisting Al, Si, and O. Zeolite’s consideration future material is due many facile synthesis methods obtain different structures variations pore size, surface area, volume physical properties. These developed using...
The esterification of free fatty acids (FFA) can be used to produce biodiesel from high FFA oils. In this work, a new eco-friendly catalyst for the oleic acid with methanol has been prepared waste material, Amazon flint kaolin, that was thermally treated (at 850 and 950 °C) activated sulfuric solutions (1 M 4 M). metakaolin samples were characterized by X-ray diffraction, scanning electron microscopy, N2 adsorption–desorption adsorption studies pyridine using TG/DTG FTIR analysis. leached at...
Two bentonites from Paraíba (Northeastern Brazil) were impregnated with heteropoly phosphomolybdic H3PMo12O40 (HPMo). The materials produced characterized by various techniques such as N2 adsorption-desorption (specific surface area, SSA), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Thermogravimetric analysis (TGA/DTG), Scanning Electron Microscopy (SEM) equipped Dispersive Energy (EDS), ultraviolet-visible (UV-vis), acid-base titration analysis. catalytic...
The growing global demand for renewable energy sources can be reached using biofuels such as biodiesel, example. most used route to produce biodiesel is the transesterification reaction of oils or fats with short-chain alcohols, generating fatty acid esters (biodiesel) and a very important by-product, glycerol (Gly). Gly widely in different sectors industry, order add value this heterogeneous catalysis becomes relevant tool, whether transform into other chemical products interest even use it...
Glycerol is a platform molecule allowing the production of high value-added molecules with numerous industrial applications in many different fields.
Recent advances in long-read sequencing (LRS) and assembly algorithms have made it possible to create highly complete genome assemblies for humans, animals, plants other eukaryotes. However, there is a need ongoing development improve accessibility affordability of the required data, increase range usable sample types, reliably resolve most challenging, repetitive regions. 'Cornetto' new experimental paradigm which process adaptively integrated with programmable selective nanopore...
The esterification of free fatty acids (FFA) is an alternative for the production biodiesel from oils with high concentrations FFA. In this paper, catalysts oleic acid methanol were prepared two Amazon kaolins (Century and flint) standard (KGa-1b KGa-2) that thermally treated at 950 °C leached 4 M sulfuric solutions. activated metakaolin samples characterized by X-ray diffraction, scanning electron microscopy, N2 adsorption–desorption pyridine adsorption studies using TG/DTG FTIR analysis....
Chitosan comprises polymeric macromolecules with technical and biological properties that have been used in biomedical healing applications requiring anti-microbial anti-inflammatory capacities worldwide. In the tropical regions, green banana peel extract andiroba oil are considered natural products wound properties. The present study, for first time, synthesized chitosan/green extract/andiroba (CGA) membranes analyzed them using scanning electron microscopy (SEM) swelling moisture tests....
The distillate produced by deodorization of palm oil (DDPO) is a waste that corresponds to 4% the product formed in this process. DDPO 83% free fatty acids (FFA), making it good material for biodiesel production. In paper, catalyst prepared from material, Amazon flint kaolin, was used esterification with methanol. Leached metakaolin treated at 950°C and activated 4M sulfuric acid (labeled as MF9S4) offered maximum activity (92.8%) 160°C DDPO:methanol molar ratio 1:60 4-h reaction time....
Amazon flint kaolin, considered useless from an economic and industrial point of view, was calcined at 850 950 °C to obtain metakaolin samples. These samples were subsequently treated with sulfuric acid (4 M) by assisted heating microwave radiation. The prepared characterized X-ray diffraction, scanning electron microscopy N2 physisorption; the surface acidity determined titration 0.2 M KOH. materials obtained used as catalysts in esterification oleic methanol. Metakaolin that activated 400...
The biotechnological potential of 8 Amazon cyanobacteria was studied and some species shown to be promising biodiesel source.
Developing a biomimetic material to wound care is an emerging need for the healing process. Poly (ε-caprolactone) (PCL) polymer with necessary dressing’s requirements often used in medicine. Their surface, physic-chemical and biological properties can be modified by adding bioactive compounds, such as andiroba seed oil (Carapa guianensis). This Amazonian natural plant has medicinal pharmacological properties. For this purpose, PCL polymeric films incorporated were investigated. The synthesis...
