Design and Commercial Validation of a Hierarchical Three-Tier Quality GradingSystem for Post-Industrial and Post-Consumer Recycled Thermoplastic Resins in US Industrial SupplyChains
Abstract: Quality grading systems for recycled thermoplastic resins providing industrial buyers with a standardized, documented quality classification framework for secondary raw material procurement are a foundational requirement for the reliable integration of recycled materials into industrial supply chains. Despite this requirement, no standardized grading scale has been established for post- industrial and post-consumer PP, HDPE, and LDPE resins in industrial supply chain contexts. This paper presents the design, operational implementation, and …

Investigation of Tangential Shear Stress and Frictional Torque Coefficient over a Rotating Disk of the Rotor-Stator System
Abstract: Abstract The study investigates the prediction of tangential shear stress and the frictional torque coefficient over a rotating disk in a rotor-stator system under laminar inward flow conditions. The interaction between the rotating and stationary disks is governed by key parameters, such as volumetric flow rate, rotational speed of the disk, and the axial clearance between the two surfaces. These parameters are expressed in terms of dimensionless quantities, including the …

Different type of catalysts used in the Baylis-Hillman reaction
Abstract: The Baylis-Hillman reaction in the present-day version is an atom-economic carbon-carbon bond-forming reaction between the α-position of the activated alkenes and carbon electrophiles under the influence of a catalyst or catalytic system offering diverse classes of densely functionalized molecules. If the substrate contains both the activated alkene and electrophile components in appropriate positions, there is the possibility of developing an intramolecular version of this reaction leading to the synthesis of …
