Multilayer Flexible Packaging Waste (MFPW) represents the largest fraction of packaging waste and is mainly composed multiple plastic films laminated with Al foil.
In this study, graphene nanosheets (GNs) were incorporated into polyethersulfone (PES) by phase inversion approach for preparing PES-GNs mixed matrix membranes (MMMs). To investigate the impact of filler content on membrane surface morphology, thermal stability, chemical composition, porosity and mechanical properties, MMMs constructed with various GNs loadings (0.01, 0.02, 0.03, 0.04 wt%). The performance prepared was tested separation selectivity CO2, N2, H2 CH4 gases at pressures from 1...
Abstract The rate of delayed hydride cracking (DHC) has been measured in Zircaloy-4 fuel cladding several metallurgical conditions using the pin-loading tension technique. In light water reactor (LWR) cold-worked and stress-relieved conditions, followed Arrhenius behavior up to about 280 °C, but at higher temperatures declined with no above 300°C. Non-LWR appeared behave same manner. LWR recrystallized condition, was highly variable because it depended on KI within test range 25 MPa√m,...
This study conducted an in-depth examination of the delamination process multi-layer packaging waste (MLPW) recycling, intending to find effective solution for recycling MLPW. The such materials can be challenging due complexity separating different layers and components. However, this proposed using nitric acid facilitate recover polymers from multilayer food packaging—the research aimed investigate mechanical properties obtained through method. Our on polymer exposed chemicals revealed...
In order to implement timely sustainability solutions, road transportation is gradually transitioning electric power. However, the maritime sector faces challenges in finding ways shift towards more sustainable fuel. From perspective of long-distance shipping, transport economically impractical. Therefore, alternative solutions or proposals contributing global reduction pollutant gas emissions are vitally important. This investigation aims find that enhance ecological efficiency...
Abstract Recently the reactors of both units Ignalina NPP in Lithuania were shutdown for decommissioning (in 2004 and 2009). According to design, spent fuel should be returned reprocessing Russia. However, up now, all assemblies are still stored pools dry storage facility on-site NPP. Thus, safety justification short intermediate term is very important. The most important barrier, preventing release radioactivity from matrix environment rod cladding. condition (integrity) cladding at end may...
Goal of this research was to find out if reorientation can influence cladding failure and determine conditions possible mechanism failure. Reorientation tests were done on zircaloy nuclear fuel specimens. Specimens made having two triangular notches along specimen axis which are similar the surface flaw that form during operation. Loading applied using PLT loading fixture give stress proportional a distance from front. When loaded, cooled 340 40 °C at cooling rate 0.25 °/min., total duration...
