Two high-capacity thiol functionalized adsorbents are prepared, using sol−gel processing, and applied to the removal of lead(II) from aqueous streams. The first adsorbent (SN) is prepared by co-condensing oligomers tetraethoxysilane (TEOS) 3-mercaptopropyltrimethoxysilane (MPS); second (MI) synthesized a combined co-condensation/molecular imprinting route TEOS MPS. resulting physicochemical properties investigated nitrogen sorption measurements, elemental analysis, Fourier transform infrared...
The present work inspects the preparation of bio-composites cassava starch with particles eucalyptus wood through application a novel method thermal compression. Bio-composites different amounts (5 to 30%), particle sizes 4 and 8 mm, were obtained. Chemical mechanical evaluation these samples was carried out using optical microscopy, infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), moisture absorption effect. effect amount size tested by comparison...
Abstract In this work, biocomposites made of polyhydroxyalkanoates (PHA) with natural fibers were produced via compression molding. particular, polyhydroxybutyrate (PHB) and polyhydroxybutyrate‐co‐hydroxyvalerate (PHBV) reinforced 20 wt% agave fibers. Different compatibilization strategies investigated to improve the fiber‐matrix interaction: fiber surface treatment in PHA solution, maleated propionylation, extrusion PHA. The characterized terms morphology, mechanical properties, water...
Abstract Wood is one of the most versatile materials, including religious symbols and carved works art. However, it a material that vulnerable to biodeterioration by insects, fungi, other organisms. Biodeterioration xylophagous insects main problems for conservation wooden objects; however, control methods are focused on insecticides which can be harmful toxic humans environment. In this work, use zinc oxide nanoparticles obtained green synthesis with an aqueous extract agro-industrial waste...
Two materials, pure poly(acrylic acid) (PAA) and nanocomposites with a matrix of PAA carbon nanotubes (CNTs) as reinforcing agent were synthesized by semi-continuous heterophase polymerization (SHP). CNTs prepared chemical vapor deposition technique purified steam. characterized high resolution scanning electron microscopy (HRSEM) Raman Fourier transform infrared spectroscopies. Nanocomposites with: (i) (CNTsp) or (ii) functionalized possessing an acyl chloride moiety (CNTsOCl). In both...
In this study, two different surface treatments were evaluated to improve the compatibility of coir fibers with poly(lactic acid). The chemical modifications achieved by fiber treatment a maleic anhydride grafted acid) (MAPLA) solution or poly(methyl vinyl ether‐alt‐maleic anhydride) (MA‐c‐PMVE) aqueous solution. analyzed attenuated total reflectance‐Fourier transform infrared determine type and level modification. biocomposites compounded via extrusion molded injection. Mechanical testing...
LysCel is a cellulose-based material in which l-lysine molecules are grafted with their amino side chains to the cellulose hydroxyl groups. This modification increases considerably mechanical strength and resistance of cellulosic structures toward water. It has been attributed formation double salt bridges between lysine aminocarboxyl groups zwitterionic state. In order characterize this unusual structure, we have performed high-resolution solid-state 15N 13C CPMAS NMR experiments on samples...
Acmella radicans (Asteraceae) is a plant native to America. Despite it having medicinal attributes, studies on its phytochemical properties are scarce, and biotechnological do not exist for this species. In study, we established an adventitious root culture from A. internodal segments in shake flasks with indole-3-butyric acid (IBA), then elicited jasmonic (JA) salicylic (SA). The total phenolic content antioxidant activity were evaluated, comparison was made using vitro plantlets wild...
The discharges enriched with heavy metals, particularly Cr(VI), are a serious environmental problem. In this work, it is presented the use of biosorbents from eggshells membranes ostrich, quail, duck and chicken; were easily prepared studied for removal Cr(VI) aqueous solutions. Maximum uptake 1.41 mmol g −1 membrane permitted identification ostrich as material highest uptake. N 2 adsorption experiments to classify mesoporous materials, since they had pore size 14.8 nm. This represented an...
Gold nanoparticles (AuNPs) stabilized by imidazolium salts derived from amino acids [glycine (1), rac-alanine (2), l-phenylalanine (3), and rac-methionine (4)] were prepared. The AuNPs the most 4, which kept particles dispersed in water for months at pH > 5.5. These exhibited a well-defined absorption band 517 nm had an average particle size of 11.21 ± 0.07 nm. 4-AuNPs reversibly aggregated controlling solution. Chiral R,R-4-AuNPs S,S-4-AuNPs synthesized, chiral environment on nanoparticle...
