Influence of annealing-induced phase separation on the shape memory effect of graphene-based thermoplastic polyurethane nanocomposites

Abstract: Thermoplastic polyurethane (TPU) is a multiblock copolymer that exhibits an attractive shape memory effect (SME). Its morphology consists of a soft segment (SS), which corresponds to the polyol or a long-chain diol, while the hard segment involves the intercalation of a diisocyanate and a chain extender. Due to the Leia mais…

The modeling and simulation of waste recovery processes applied to the Orange juice industry

Abstract: Orange-juice production represents a significant, world-leading economic sector in Brazil. Orange processing residues, however, correspond to 50% to 60% of the in natura fruit mass. Despite the high amount of generated waste, which is disposed of in landfills or used as raw material to produce low-value animal feed, studies Leia mais…

Agarose fibers with glycerol and graphene oxide and functional properties for potential application in biomateirals

Abstract: Agarose has numerous applications in biochemistry and medical textiles. This study aimed to produce agarose graphene oxide-glycerol fibers and analyze their properties. The agarose gel was prepared by dissolving the polymer in 9:1 (v/v) dimethyl sulfoxide (DMSO): H2O, followed by spinning in an ethanol bath (1:1 (v/v) ethanol: H2O) Leia mais…

Characterization of na inactive dumpsite using electrical resistivity tomography and hydrochemcical data: a case study in Brazil

Abstract: Open dumping is one of the most common solid waste disposal methods in developing countries. As they lack planning and basic environmental protection engineering measures, dumpsites represent environmental and health risks that should be investigated. However, several dumpsites are abandoned without appropriate land-use management, difculting their proper environmental assessment. Leia mais…

Feasibility of laser-induced breakdown spectroscopy for determinations of neodymium in magnet alloys

Abstract: The quantification of rare earth elements in (Nd-Pr)-FeB alloys used in the production of super magnets is required to ensure the quality of the raw material and a final product with suitable properties. Laser-induced breakdown spectroscopy is attractive to this aim by avoiding the need for decomposition of the Leia mais…
