“…Applications of clay-nanocomposites are diverse. Nanoclay technology is in high demand in automotives, from interior and exterior car parts to tires, sporting goods, packaging, coatings, wire and cables, fuel cells, and aerospace industries (for example, PMMA (poly(methyl methcrylate)-epoxy-nanoclay composites, polypropylene-nanoclay composites, polyvinylidene fluoride nanoclay-nanocomposites and nanoclay-modified rigid polyurethane foam) . The biomedical applications of nanoclay-composite materials are reviewed by Peña-Parás and the group .…”

Clay-nanocomposite materials have been widely exploited as drug delivery systems, but their application in agriculture is less explored. In clay-nanocomposite, the combination of nanoclay and the active ingredient (i.e., metal, nonmetal, oxide nanoparticles) can produce a biocompatible and environmentally friendly delivery vehicle of micronutrients, pesticides, etc. for better crop growth. Clay-nanocomposites have been researched to address the problem of nontarget effects of agrochemicals, their leaching into groundwater, and the fast breakdown of sprayed chemicals. Here, we present a review of the synthesis of clay-based nanocomposites and their application as a delivery vehicle for agrochemicals and nucleic acids, as well as their antimicrobial properties. This review would be helpful in identifying and addressing the current issues of the delivery of active ingredients and biological macromolecules for crop protection, improved growth, and sustainability.

The cold chain is responsible for perishable products preservation and transportation, maintaining a proper temperature to slow biological decay processes. Often the efficiency of the cold chain is less than ideal, significantly increasing food waste and energy consumption. Refrigerated transport is a critical phase of the cold chain because of its negative impact on energy consumption and greenhouse gas emissions. It is estimated that around 15% of global fossil fuel energy is used in the refrigerated transport sector, so there has been a growing interest in the last decades in the optimization of these systems in order to reduce their environmental impact. Vapor compression refrigeration units, usually powered by means of a diesel engine, are the most commonly used systems in road refrigerated transport. This paper provides a review of (a) currently used systems and alternative technologies that could reduce the environmental impacts of road refrigerated transport and (b) optimization models and methods used to minimize fuel/energy consumption and greenhouse gas emissions, focusing both on reducing the thermal loads and solving the refrigerated vehicle routing problem.

“…PP not only used for its excellent corrosion resistance and easy to manufacture but also an insulation in the sandwiched material used for refrigerated vehicle walls box panel with the potentials of weight reduction, low thermal conductivity, reduction in engine power, CO2 gas emissions, fuel consumption and cost saving. Uwa et al, [14] introduced, in their study, the composite of PPMAPPNC (Polypropylene (PP) /Maleic-Anhydride-grafted-Polypropylene (MAPP)/ Nano clay). Test results revealed that tensile strength and stiffness improved with low clay contents.…”

“…Thermal conductivity analysis showed that composites with high proportion of clay have high resistance to heat. PP98MAPP4NC3 composite was optimal, and could be used as a better replacement to the conventional sheets in Refrigerated Vehicles [14]. Liu et al, [15] compared the metal and plastic bi-directional tidal turbine rotor models by experimentally evaluate the performance, in which result showed a substantial decrease in maximum power performance for the plastic rotors -about 40% decrease at a tip speed ratio of around 3.0 compared with the metal rotors.…”

The high-performance plastics usage is increasing in the automobile field because of its advantages over other metals and alloys. Corrosion resistance, light weight, low cost, flexibility in design are the major advantages of plastics above the conventional metallic materials. In this paper a metal version component converted into plastic version in order to increase efficiency, reduce the overall cost of a two-wheeler and to improve the production rate of component. Different types of material such as PP + 15% TALC, PP + 30% GF, PP + 30% TALC, Nylon 6 + 15% GF, Nylon 66 UF, Nylon 6 UF, Nylon 66 + 30% GF, ASA LI941 and ASA LI913 tested for 10,000km road test, vibration test and fitment test. An injection moulding used to produce the component and ‘Mouldx3D’ software was used for mould flow analysis and other simulation. The different parts of injection moulding tool made up of C45, P20 and D2 materials. Among different materials, ASA LI913 was selected since it has better weather resistance than others and the impact strength matched to metal version component. Finally, it was found that the cost of the component made of Plastic considerably less than same component made of metal.
