In this study, the effect of fish waste powder, base material polyethylene , and also the quantity of coupling agent (MAPE) on physical and mechanical properties of wood-plastic composite were studied. For this purpose, wood powder at 40% was mixed with 60% of HDPE. Fish waste in three levels (5, 10 and 15%) mixed int…
This study shows the possibility of tuning microstructure and magnetic properties of cobalt ferrite powders produced by co-precipitation and subsequently processed by ultra-fast milling. Short milling times (3 minutes) are sufficient to obtain high coercive isotropic powders for permanent magnet applications.
In this study, chemical treatments of rice husk flour on physical and mechanical properties of rice husk flour / high density polyethylene composites were studied. Rice husk was milled and its flour through the sieve of 60 meshes was selected for using. Initially, dried rice husk flour was subjected to chemical treatm…

Transmission properties of a linear chain of nanorings with 6 quantum dots (QD) per ring are investigated with and without magnetic field effects. The rings are connected serially by a linear segment. A tightbinding Hamiltonian is solved exactly, giving the transmission for any number of rings in series. The Aharonov-…
Back Cover: Polyphosphate (PolyP), if encapsulated into nanoparticles, is engulfed by the target cells. In response, the gene encoding the alkaline phosphatase (ALP) is abundantly expressed and the enzyme is then translocated to the surface of the cells. Further details can be found in the article by W. E. G. Müller e…
On page 5816, Hua Kuang and co-workers report the fabrication of gold-gap-silver nanostructures (GGS NSs) with distinctive plasmon-induced chiroptical performance in the visible region. The nanogap size of the GGS NSs can be tailored by altering the amount of chiral cysteine. The chiral GGS NSs show unusual circularly…
Wormlike micellar fluids are viscoelastic and can support shear waves. Phase transitions of the micellar aggregates are temperature dependent and can manifest as sharp changes in the shear wave speed as a function of temperature. In this work, the variation of shear speed with temperature of 200 mM CTAB/NaSal micellar…
Abstract The light leakage and the color shift of an liquid crystal display (LCD) and especially vertically aligned (VA) panel drastically increases with viewing angle. Particularly for dark images the color gamut gets poorer and the color remarkably shifts with change of viewing angle. In this article, we investigate…
The switched reluctance motor (SRM) is a low cost motor option. However it has lower power factor than competing motors and this has led to the incorrect perception that the power electronics are expensive. This paper shows that using the inverse of power factor as a proxy for converter rating and hence cost is incorr…
Summary form only given. With the long-term future of fossil fuels in considerable doubt, Europe's roads are seeing the arrival of the first electric vehicles (EVs); the majority of which are hybrid EVs. Crucial to the widespread uptake of pure EVs is the development of superior next-generation electric motors; which…
This paper reports the scattering of electromagnetic plane wave by a synthetic dielectric made of one-dimensional (1D) periodically stratified dielectric layers along the radial direction. Interestingly, the bi-static echo width of the synthetic dielectric in a specific frequency range of operation is almost identical…
Abstract The organic light‐emitting diode (OLED) technology is now maturing. The unique physics and chemistry of quantum dots (QDs) result in a wider color gamut and increased stability over organic dyes meaning they have significant potential over organics in light‐emitting devices. This article reviews the state of…
Abstract The new flavonoid glycoside lancifolide A (I) is isolated from the flowers of Lilium lancifolium together with five known flavonoid glycosides.
The Landau-Lifshitz equations are generalized to the case of spin accumulation and dynamics of localized spins in the conductive magnet, in terms of the Rashba spin-orbit scattering mechanism. The effects of the spin-orbit transfer torque caused by longitudinal current flowing through the conducting heterostructure wi…
Tube-type Li-organic batteries are demonstrated by S. Y. Hong, J. Cho, and co-workers on page 5141. Prototype flexible and flowable rechargeable lithium batteries show excellent electrochemical performance under repeated mechanical bending and stretching. This concept is regarded as an effective way to operate flowabl…
