A detection system using room-temperature, microstructured solid-state thermal neutron detectors with very low leakage current has been developed at Rensselaer Polytechnic Institute (RPI) with the ability to provide positional and spectral information about an unknown neutron source. The Directional and Spectral Neutron Detection System (DSNDS) utilizes a set of small-but-scalable, zero-bias so...

Different types of recycled plastic have been used in concrete and most studies focused on the behaviour a single type plastic. However, separating wastes increases cost time processing. To tackle this problem, research presents an experimental investigation to determine effect incorporating different combinations three waste aggregates—Polyethylene terephthalate (PET), High Density Polyethylen...

This study reports an application of instrumental color measurement for quantifying and comparing the optical properties of high density polyethylene HDPE and low density polyethylene LDPE blend films and the effect of blending ratio and miscibility on these properties. The technique of spectrophotometry in transmission and reflectance modes can be used as a versatile tool to evaluate the color...

injection molding is one of the most common processes which are used for manufacturing different plastic parts. this method includes 3 continuous steps: filling of the mold, cooling and driving the part out. a wide range of plastic and non-plastic materials can be used as raw material in this process. one of the most important advantages of this way of production is that it is very economic. in...

This work is concerned with the hypothesis that lightning impulses can lead to accelerated ageing of extruded polymeric cables. The behaviour of an insulation material when suffering lightning impulses is different from that for DC or power frequency over-voltages. Shaped HDPE material samples have been manufactured using a mould tool. The samples then may be electrically aged using one of the ...

Biochar from waste has emerged as a vital solution for multiple contemporary issues. While the organic content and porous structure of biochar have granted it benefits. Where use is proven to be beneficial enhancing soil water nutrients retention ability, therefore, saving boosting yields in arid regions. Moreover, capable sequester carbon atmosphere permanently store within soil. As such, this...
