“…At very small fraction, the presence of silica slightly increases the composite stiffness due to smaller of the contact formed. When it is slightly added, its effect is more apparent as increasing of the contact formed, even at certain fraction the compressive stength attaining 40.47 MPa is maximum value, that it means that contact occured is also maximum and if the fraction is added again, the silica can not interact effectively with PU/solid waste composite due to maximum contact formed, instead it interact with the neighboring silica that increases the brittleness of composite [7,21,22]. As result the composite strength decreases.…”

Effect of turbulence modelling to predict combustion and nanoparticle production in the flame assisted spray dryer based on computational fluid dynamics AIP Conference Proceedings 1712, 040002 (2016) A solid waste composite was successfully made. Preliminary, the composite was synthesized using polyurethane (PU) as binder mixed with the solid waste using simple mixing method and then hot-pressed at at pressure of 4 metric-tons and temperature of 80 C for 20 minutes. To enhance its strength, quartz sand partilces with varied content then were added into the PU-solid waste mixture. From the compressive strength test, it was obtained that PU/solid waste composite with PU fraction (w/w) of 0.43 has optimum compressive strength of 38.91 MPa. Having been added quartz sand having average particles size of 0.94 m, its compressive strength attains maximum at 40.47 MPa for quartz sand fraction (w/w) of 4.27 x 10 -3 . The strength is comparable to that of clay brick, slate stone, sandstone, limestone, alder wood, aspen wood, black cherry and pine woods. Therefore, this composite is very adequate to compete the building materials such as the bricks, stones and woods.

Porous metal frameworks offer potentially useful applications for the aerospace, automotive and bio-medical industries. They can be used as electrodes, actuators, or as selective membrane films. The versatility of the physical features (pore size, pore depth, overall porosity and pore surface coverage) as well as the large range of surface chemistries for both metal oxides and pure noble metals offers scope to functionalise metal nano-particles and networks of nano-porous metal structures. As well as traditional routes to producing metal structures, such as metal sintering or foaming, novel high-throughput techniques have recently been investigated. Nanoparticle self-assembly, metal ion reduction and deposition as well as metal alloy de-alloying were identified as sustainable routes to produce large surface areas of such nano-porous metal frameworks. The main limitations of the current fabrication techniques include the difficulty to process stable and homogeneous arrays of nano-scale pores and the control of their morphology due to the high reactivity of nano-structured metal structures. This paper aims at critically reviewing the various fabrication techniques and surface functionalization routes used to produce advanced functional porous metal frameworks. The limitations and advantages of the different fabrication techniques will be discussed in light of the final material properties and targeted applications.

“…It is well known that the interfacial effects of nanoscale fillers have a significant role in the bulk properties of polymer composites [4,5]. Therefore, it is vital that we understand the effects of particle size and surface area on the structure and chain dynamics of polymer in the interphase region around filler aggregates, and consequently on the dielectric properties of such composites [6,7].…”

Interfacial effects on dielectric properties of ethylene propylene rubber–titania nano- and micro-composites

et al. 2015

The influence of titania particle size on dielectric properties of ethylene-propylene rubber (EPR) composites was investigated, with an emphasis on the chain dynamics in the interphase region. We hypothesized that a reduction in the conformational entropy of rubber chains in the interphase region would make the restricted chains more prone to orient along the applied electric field and increase dielectric permittivity than the chains in the bulk. The morphology and microstructure of the composites was characterized using scanning electron microscopy and atomic force microscopy, and a notable difference was detected in the average aggregate size and microstructure of the interphase between the nano-and microcomposites. We predicted that the physical attraction between nano-and micro-fillers and polymer, as characterized by the surface energy of fillers, would be similar. However, differences in the chain dynamics investigated by dynamic mechanical thermal analysis and dielectric spectroscopy confirmed the presence of more restricted chains, quantitatively and qualitatively, in the interphase region of the nanocomposites compared to the micro-composites. We concluded that the higher dielectric properties of the nanocomposites could be explained by the lower conformational entropy of chains in these composites compared to those in the micro-composites.
