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...

Abstract Microplastics are plastic particles less than 5 mm in size but larger 0.1 µm. Widespread microplastic pollution aquatic and terrestrial environment is raising serious concern globally due to its detrimental impacts on living beings. This urge for the necessity of a sensitive analytical tool, which can facilitate reliable identification microplastics. Micro-Raman spectroscopy enables mo...


 The quest to discover more and enhance the qualities of agro-residue for use as natural reinforcement polymers continues attract attention researchers because environmental friendliness. Hyphaene thebaica also known doum palm is a fruit tree native Nile in Egypt found abundance many parts Africa. Doum contains probably hardest toughest nut. nuts (DPN) are most under-used hard-nut despite...

Solubility of carbon dioxide in poly(vinyl acetate) (PVAc), poly(2,6-dimethyl-1,4-phenylene ether) (PPO), polypropylene (PP), and high-density polyethylene (HDPE), poly(butylene succinate) (PBS), poly(butylene succinate-co-adipate) (PBSA) and polystyrene (PS) are modeled by adaptive neuro-fuzzy inference system (ANFIS) in wide range of pressure and temperature. The results obtained in this work...

The mechanical properties of polyethylene (PE) materials are greatly influenced by their molecular structures, environmental temperature, and strain rate. In this study, static dynamic compression tests were performed on two semicrystalline PE materials—ultrahigh weight (UHMWPE) high-density (HDPE). stress–strain curves HDPE UHMWPE under uniaxial at temperatures −40–120 °C rates 0.001–5500 s−1 ...

The UK Dairy Roadmap has set a target of achieving 50 wt.-% high density polyethylene (HDPE) recyclate in their HDPE milk bottles. Such content will lead to the accumulation recyclates that have been subjected different number melt extrusion cycles supply chain. This work investigates structure-property relationship blending virgin (vHDPE) with these grades repeatedly melt-extruded (rHDPE). was...

The focus of this research is to investigate the potential of using exfoliated graphene nanoplatelets, GNP, as the multifunctional reinforcement in fabricating polymer/GNP nanocomposites and then explore their prospective applications in bipolar plates for polymer electrolyte membrane (PEM) fuel cells. Firstly, high density polyethylene (HDPE)/GNP nanocomposites were fabricated using the conven...

Among many lightweight materials used in marine applications, sandwich structures with syntactic foam core are promising because of lower water uptake amid face-sheets damage. HDPE (high-density polyethylene) filament is to 3D print skin, and glass microballoon (GMB) reinforced filaments for the core. The optimized parameters prepare blends 20, 40, 60 volume % GMB HDPE. These foamed extruded fo...

The aim of this study is to investigate the kinetic characteristics high-density polyethylene (HDPE) waste pyrolysis process based on thermogravimetric analysis (TGA) and using a fixed bed pyrolytic reactor (FBPR) at different temperatures. In addition, influence material thickness yield distribution composition products was examined over temperature range 425–550°C. A higher wax fraction obtai...

The influence of intensity the ?-irradiation on commercial high and low density polyethylene (LDPE HDPE) granules (Kazanorgsintez PJSC, Kazan, Tatarstan, Russia) their rheological morphological properties at irradiation doses 5 10 kGy was studied. Experiments in oscillation mode revealed an increase dynamic moduli values with increasing radiation dose compared to initial samples. At same doses,...
