Plastics Engineering is the official publication of the Society of Plastics Engineers (SPE). We provide plastics professionals with a wealth of information about machinery, technological advances, materials innovations, sustainability, and more.
CuInSe 2 single crystals, grown by the vertical Bridgman technique were studied using polarisation resolved photoluminescence (PL) at cryogenic temperatures. The emission lines related to the first ( n = 2) excited states for the A and B free excitons were observed in the PL spectra at 1.0481 and 1.0516 eV, respective…

Titanate nanotube (TN) synthesized by hydrothermal reaction of titania nanoparticles in alkali solution, then the TNs were modified by acetamide. X-ray diffraction analyses, scanning electron microscopy and Fourier transform infrared spectrometry are used to determine the structure of the TNs. Under DC electric field,…

The SiC/FexSiycomposites were synthesized by reaction sintering process with iron tailings as raw material and carbon as reductant. The room and high temperature flexural strengths and fracture toughness of composites were studied in this paper. Fracture surfaces were observed by means of a scanning electron microscop…
Using the method of differential subordination, we investigate some properties of certain classes of multivalent functions, which are defined by means of convolution.
Nowadays, power converters in the railway industries are increasingly more compact and powerful. This progress is due to the use of fast and efficient components capable of working at high frequency such as IGBT. However, this evolution leads to a considerable loss of harmonics in transformers and complicates their de…
The fabrication of ferroelectric nanocrystal materials such as Pb(Zr,Ti)O3has been widely researched because of the development of high capacity ferroelectric random access memory devices (FeRAM) and ferroelectric domain physics at the nano scale. The ultra flat surface of electrically conductive materials such as Pt…
A facile route to synthesis silver nanoparticles into polyvinylpyrrolidone (PVP) or silica (SiO2) matrices using sol-gel method has been developed. The influence of matrices on the size and optical properties of silver nanoparticles were studied. Because the particle size increases at different rate with silver nitrat…
Nitrogen oxides (NOx) are one kind of harmful substances causing serious pollution on atmospheric environment. Characteristics of NOx from coal-fired utility boilers are massive and lean. In this paper, large coal-fired boilers were chosen as the object, NOx formation mechanism and control were studied, and comparativ…
The inclusions are to a large extent prevented from contamination and many temporal changes as they are embedded within minerals. However, an essential part of the investigation procedure is the method of extracting fluids from such minerals. Since mechanical drilling or polishing involves a high risk for contaminatio…
Ultrasound contrast harmonic imaging techniques based on shelled microbubbles' nonlinear oscillation have been used in clinical diagnosis successfully, however a parameter characterizing the nonlinear scattering properties of a single bubble has not been found yet. In this study, based on Church Hoff equation describi…
The low-frequency dielectric function and conductivity at ferroelectric phase transition have been analyzed in monoclinic TlInS2 crystals doped with different impurities. Complementary, room-temperature optical absorption and photoconductivity have been examined to identify shallow and deep energy levels caused by the…
One-dimensional SrSn(OH)6nanowires were successfully synthesized through a rapid simple methods sonochemical synthesis at room temperature without using any templates or surfactants. The growth mechanism has been proposed, and the reaction conditions were carefully investigated. The experimental results revealed that…
This paper reports on the first demonstration of high-Q 1D photonic crystal nanocavities in the chalcogenide glass Ge11.5As24Se64.5. This material has a high nonlinear figure of merit due to its low two-photon absorption and large Kerr nonlinear coefficient, making it ideal for ultrafast switching applications. The ca…
Experiments were conducted to investigate the decolorization of methyl orange simulated wastewater in order to assess the effectiveness and feasibility of ultrasound(US) enhanced high-purity chlorine dioxide(ClO2) oxidation process. The results showed that in ClO2/US system the decolorization rate of methyl orange was…
To prevent the silica scale formation in the geothermal water recycling process, the silicic acid perfectly removed from geothermal water as calcium silicate by calcium nitrate. Ordered mesoporous silica was synthesized at strong acidic condition by using low cost calcium silicate as silicon source, which was separate…
In this contribution, the simultaneous and switchable laser operation is reported at 523 nm and 640 nm. A dual wavelength laser operation at 607 nm and 640 nm of Pr:YLF was previously obtained by the use of intracavity prisms.
