Electroactive hydrogels were prepared using commercial citric pectin, either raw (PC) or purified through dialysis (dPC), and chemically synthesized polypyrrole (PPy). 1H NMR analyses showed that PC is a low methoxyl pectin (degree of methoxylation, DM=46%) and dPC is a high methoxyl pectin (DM=77%). The pyrrole polymerization was monitored through UV-vis spectroscopy and both samples were observed to be good stabilizers for PPy in aqueous medium. The dispersions were used to prepare the hydrogels h- ...

Biopolymer-based hydrogel electrolytes can be described as alternative materials for supercapacitors due to their good ionic conductivity, no liquid leakage, and no toxicity, allowing the construction of flexible devices. This work reports the preparation of alginate gels crosslinked with Ca2+, H+, and a combination of Ca2+ and H+, for use as electrolytes in a symmetric supercapacitor with polyaniline (PANI) films as electrodes. Results indicated that the gel formed with both Ca2+ and H+ showed to ...

Electroactive nanoparticles combining gum arabic (GA) and polyaniline (PANI) were prepared by chemical synthesis. The gum consists of highly branched anionic polysaccharides with some protein content. GA was structurally modified by Smith controlled degradation, in order to reduce its degree of branching (GAD), aiming the elucidation of the relationship between the structure and the properties of complex polysaccharides. The modification was studied by SEC, GC–MS, 13C NMR and colorimetric methods. ...

Research and development of conductive nanomaterials based on biocompatible matrices has been greatly rising in the past decade since synergistic properties can be achieved by combining metallic nanoparticles and natural/conductive polymers. Poly(3,4-ethylenedioxythiophene) (PEDOT) is known to be an intrinsically conductive polymer, difficult to handle in aqueous medium. Therefore, in this work, we present a physical-chemical perspective in the development of novel aqueous dispersible nanocomposites ...

Abstract Developing new flexible and electroactive materials is a significant challenge to producing safe, reliable, and environmentally friendly energy storage devices. This study introduces a promising electrolyte system that fulfills these requirements. First, polypyrrole (PPy) nanotubes are electropolymerized in graphite‐thread electrodes using methyl orange (MO) templates in an acidic medium. The modification increases the conductivity and does not compromise the flexibility of the electrodes. ...

This work dealt with the morphology and permeability properties of polypropylene/organoclay nanocomposites prepared using an acrylic acid grafted polypropylene (PP-g-AA) as compatibilizing agent. Two PP-g-AA containing the same acrylic acid content (6 wt.%) and having different molar masses were tested. The o-MMT content was 0, 1 or 5 wt.% and the PP-g-AA/o–MMT mass ratio was 0/1, 1/1, 2/1 or 5/1. Results of wide angle X-ray scattering (WAXS) and transmission electron microscopy (TEM) showed that without ...

The chemical investigation of Heliotropium transalpinum var. transalpinum Vell. (Boraginaceae) led to the isolation of transalpinecine (1), a novel pyrrolizidine alkaloid, in addition to known alkaloids subulacine (1β-2β-epoxy-1α-hydroxymethyl-8α-pyrrolizidine) (2), and 1α-2α-epoxy-1β-hydroxymethyl-8α-pyrrolizidine (3). The structures of the isolated compounds were elucidated based on spectroscopic data and theoretical calculations.

Photoacoustic spectroscopy (PAS) was applied as a method to quantify dyed food samples, and was compared with First Derivative Spectrophotometry (FDS). The dyes Brilliant Blue (B), Sunset Yellow (S) and Tartrazine (T), which are common food additives, were employed for the comparisons. Polyester-type Polyurethane (PU) foam was used for extraction of the dyes from a solution containing the food matrix. For the spectrophotometric determinations, the adsorbed dyes were recovered by using dimethylformamide. ...

Micellar aggregates produced in DMF (selective solvent for polystyrene) from the same set of samples were previously successfully characterized through light scattering measurements. The X-ray scattering profiles of starlike (from the diblock copolymer sample) and flowerlike ...

Transesterification and epoxide ring-opening reactions are two mechanism routes that explain chemical modifications of macromolecules by glycidyl methacrylate (GMA). Although the coupling reaction of the GMA with macromolecules has widely been investigated, there are still mechanisms that remain to be explained when GMA is processed in an aqueous solution at different pH conditions. To this end, reaction mechanisms of poly(vinyl alcohol) (PVA) and poly(acrylic acid) (PAAc) by GMA in water in acidic ...

Aortic root (AoR) dilatation is more frequently observed in hypertensive individuals and is independently associated with left ventricular (LV) hypertrophy. Although the LV structure has sex-specific predictors, it remains unknown whether there are gender-related differences in the determinants of AoR size. We carried out a cross-sectional analysis of clinical, laboratory, anthropometric, funduscopic and echocardiographic features of 438 hypertensive patients with LV hypertrophy (266 women and 172 ...

A new morphology of crew-cut aggregates prepared from highly asymmetric triblock copolymers of 5-(N,N-diethylamino)isoprene and styrene in dilute solution is reported. After quaternization of the polar block, using dimethyl sulfate, the copolymers consist of a long block of polystyrene (PS) with short poly[5-(N,N,N-diethylmethylammonium)isoprene] (PAI) blocks at both chain ends. The aggregates were prepared by first dissolving the copolymers in a common solvent for both blocks and then adding water ...

The objective of this work was to investigate co-dried fish silage as an alternative animal protein source for diets of pacu, Piaractus mesopotamicus.The diets did not differ significantly (P >0.05) with respect to average weight gain, ration consumption, apparent feed conversion, protein efficiency and specific growth rates. However, apparent protein digestibility ...
