Pecan nutshell (PNS) is generally treated as a residue or being used in low value applications. The understanding of thermal, chemical and morphologic characteristics PNS great importance to determinate its application field possibilities. There are some studies for applications, but none them characterized it polymer composites application. So, this study intends characterize focusing on polymeric were through morphological, thermal analysis. Degradation kinetics was performed...
Abstract Purpose Time to closure and morbidity are significant issues associated with ileostomy reversal after rectal cancer resection. This study aimed investigate the rate, time, procedure. Methods Between February December 2022, patients who underwent protective surgery across 45 Italian surgical centres were prospectively included. Data on times, methods, complications collected analyzed. Both univariate multivariate statistical tests employed assess stoma rates occurrence of...
ABSTRACT Poly(lactic acid) (PLA), the polymer object of this study, degrades by a biotic process after an abiotic hydrolysis process. Its degradation was evaluated 600 days exposure in simulated marine environment (SME), as buriti fiber‐reinforced composites having triacetin coupling agent. Composites were obtained extrusion and films produced compression molding. After between 60 exposure, PLA had weight loss 2.5%, PLA/T 1.5%, 10–12% for PLA/B PLA/B/T, respectively. intercalates reduction,...
Abstract Purpose The incidence of inguinal hernia is higher in elderly because aging-related diseases like prostatism, bronchitis, collagen laxity. A conservative management common to reduce surgery-related risks, however watchful waiting can expose obstruction and strangulation. aim the present study was assess impact emergency surgery a large series with complicated groin identify independent risk factors for postoperative morbidity mortality. predictive performance prognostic scores has...
Powder coatings have been used for coating metal substrates in industrial applications. The incorporation of nanofillers as muscovite mica and montmorillonite (MMT) can improve the properties coatings. objective this study is to develop, apply characterize a hybrid powder (30% epoxy/70% polyester) adding concentrations 2, 4 6 phr separately twin screw extruder. characterization was performed by thermal, mechanical chemical analysis. clay into polymer increased surface roughness resulting...
Polymer coatings have been used for the corrosion protection of metal surfaces acting as a physical barrier against several corroding media. In spite good efficiency these their resistance is limited due to presence localized defects which give place corrosion. Aiming improve properties this work has proposed use nanocomposites powder based on standard formulation commercial varnish. Nanocomposites with 2 and 4 wt% contents organophilic montmorillonite (OMMT) were obtained in molten state...
ABSTRACT Polypropylene (PP) and polyethylene (PE) are two of the most widely used polymers in world, consequently main polymer waste that contributes to pollution oceans. Because they considered inert degradation, such becomes a threat marine life. In this study, it was possible collect data on recyclability PP PE collected from Great Pacific Garbage Patch. First, degradation conditions suffered by these materials were evaluated. The Fourier transform infrared spectroscopy assays presented...
Abstract Background Frailty assessment has acquired an increasing importance in recent years and it been demonstrated that this vulnerable profile predisposes elderly patients to a worse outcome after surgery. Therefore, becomes paramount perform accurate stratification of surgical risk undergoing emergency Study design 1024 older than 65 who required urgent procedures were prospectively recruited from 38 Italian centers participating the multicentric FRAILESEL (Frailty Emergency Surgery...
Abstract Heterogeneous photocatalysis represents a solution for several environmental problems. However, achieving photocatalyst separation from reaction media on large scale remains challenge, one that might be overcome by the immobilization of photocatalysts into supports. To this end, composites polyvinylidene fluoride and zinc oxide (ZnO) were prepared three different techniques: mixing (SM) followed Nonsolvent Induced Phase Separation; melt blending at both low‐ high‐shear rates (LS HS)...
ABSTRACT Despite the efforts of scientific community, carrying out photocatalyst immobilization so that industrial application photocatalysis becomes economically feasible is still a challenge to be overcome. In this work, polyvinylidene fluoride (PVDF)/ZnO composites were prepared by solution mixing based on solid knowledge membrane technology and with help powerful experimental design for systematic evaluation interaction among variables. A strategy variable screening was used, followed...
ABSTRACT Powder coatings have been receiving attention because they are environmentally friendly. They do not contain solvents in their composition, and components decorative corrosion‐protection functions, among many others. However, the presence of polymers composition increases risk combustion adverse situations. In this context, study aims to develop characterize acrylic‐based powder paints with addition 2 wt % 4 montmorillonite clays (MMT) as Cloisite 30B (MMT‐30B) 15A (MTT‐15A),...
