Development and dynamic simulation of single screw extruder for the production of cassava and yam starch nanocomposites CIGR Journal
Fadeyibi, Adeshina; Osunde, Zinash Delebo; Gbabo, Agidi; Egwim, Evans Chidi.
A research was conducted to develop a single screw extruder from a locally available material for the mixing and homogenization of bulk solids, such as the composites of cassava and yam starch-glycerol with nanoparticles. The design was made by computing the hopper outlet size, shaft diameter, screw geometry, barrel volume and the capacity of the conveyor, empirically. The stresses in the conical section of the hopper were also evaluated to assess its load requirement, thus avoiding any problem associated with the flow of materials through the hopper opening. The extruder was dynamically simulated to assess its throughput at the feeding, compression and metering zones. This was done by investigating the dynamic effect of the time of operation, with respect...

Surface, thermal and hemocompatible properties of novel single stage electrospun nanocomposites comprising polyurethane blended with bio oilTM Anais da ABC (AABC)
AYYAR,MANIKANDAN; MANI,MOHAN PRASATH; JAGANATHAN,SARAVANA KUMAR; RATHINASAMY,RAJASEKAR; KHUDZARI,AHMAD ZAHRAN; KRISHNASAMY,NAVANEETHA PANDIYARAJ.
ABSTRACT In this work, the physicochemical and blood compatibility properties of prepared PU/Bio oil nanocomposites were investigated. Scanning electron microscope (SEM) studies revealed the reduction of mean fiber diameter (709 ± 211 nm) compared to the pristine PU (969 nm ± 217 nm). Fourier transform infrared spectroscopy (FTIR) analysis exposed the characteristic peaks of pristine PU. Composite peak intensities were decreased insinuating the interaction of the bio oilTM with the PU. Contact angle analysis portrayed the hydrophobic nature of the fabricated patch compared to pristine PU. Thermal gravimetric analysis (TGA) depicted the better thermal stability of the novel nanocomposite patch and its different thermal behavior in contrast with the pristine...

Potential applications of nanotechnology in the agro-food sector Ciênc. Tecnol. Aliment.
García,Mario; Forbe,Tamara; Gonzalez,Eric.
Nanoscience and nanotechnology are new frontiers of this century. Their application to the agriculture and food sectors is relatively recent compared with their use in drug delivery and pharmaceuticals. Smart delivery of nutrients, bioseparation of proteins, rapid sampling of biological and chemical contaminants, and nanoencapsulation of nutraceuticals are some of the emerging topics of nanotechnology for food and agriculture. In this review, some applications of nanotechnology in agro-food sector are discussed.

Rapid protocol to evaluate the photoprotective effect of film-forming formulations on mangoes Rev. Bras. Frutic.
Araújo,Ana Laressa Feitosa; Britto,Douglas de.
Abstract Sunburn is responsible for significant losses in post-harvest and has motivated studies to diminish its effect on different types of cultivars. Thus, the present study proposes a rapid protocol to evaluate the photoprotective effect of suppressive formulations. The experiment consisted in placing fruits (mango) covered with different suppressor formulations about 7 centimeters from an incandescent source and measuring the surface temperature variation employing a thermometer and thermal camera. The formulations were based on a filmogenic polysaccharide (galactomannan) and reflective additives (hydroxyapatite, montmorillonite and bentonite clays). The best result was achieved with a coating with bentonite as an additive, which showed a statistical...
