Analysis of Thermal Dynamics of Floating Photovoltaic Systems

Solar RRL, EarlyView.
A scalable methodology couples computational fluid dynamics‐derived wind decay functions with a dynamic heat transfer model to capture spatial temperature variations across large floating photovoltaic systems and is validated with data from the Netherlands floating photovoltaic systems (FPV) site.

Processing Stabilization of Polyolefin Recyclates Using Alditols in Combination With α‐Tocopherol: A Sustainable Alternative to Phosphites

Journal of Vinyl and Additive Technology, EarlyView.
A novel bio‐based stabilizer system significantly improves the quality of polyolefin recyclates during multiple recycling cycles. ABSTRACT This study introduces a novel bio‐based stabilizer system for polyolefin recyclates that combines alditols with small amounts of α‐tocopherol as a sustainable alternative to conventional phosphite additives. The aim

Microplastic Detectability Investigation in Soils Using X‐Ray Microtomography

X-Ray Spectrometry, EarlyView.
ABSTRACT X‐ray microtomography (microCT) is a promising tool for investigating microplastic (MP) contamination in soils, offering non‐destructive 3D visualization and quantitative analysis of particles embedded in complex matrices. This study evaluated its applicability by mixing plastic fragments (PET, PEHD, PS, and PP) with humus‐rich and sandy soils

Physics‐Driven Deep Neural Networks for Solving the Optimal Transport Problem Associated With the Monge–Ampère Equation

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Monge–Ampère equations (MAEs) are fully nonlinear second‐order partial differential equations (PDEs), which are closely related to various fields including optimal transport (OT) theory, geometrical optics and affine geometry. Despite their significance, MAEs are extremely challenging to solve.

Dielectric Loss Suppression of Polyethylene Cable Insulation by Motion Restriction of Ultralow‐Content Grafted Maleic Anhydride

High Voltage, EarlyView.
ABSTRACT Maleic anhydride (MAH) grafting modification is an effective approach to enhance the insulating performance of polyethylene (PE) cable insulations. However, the high polarity of MAH often causes considerable dielectric loss, making it unsuitable for AC systems.

An investigation of the improvements of mechanical and thermal properties of high-density polyethene/nano clay composites

European Mechanical Science, 2019
The incorporation of different loadings of nanoclay (NC) into high-density polyethylene (HDPE) was studied. A series of different ratios of NC (2, 4, and 8 wt %) in fixed particle size, 300μm was blended with HDPE matrix and prepared via melt mixing ...

Cost–benefit analysis of landfill emergency securing: Two applications in Southern Italy

Annals of Public and Cooperative Economics, EarlyView.
Abstract The systematic use of landfills as a method of waste disposal is leaving a heavy legacy in terms of environmental pollution, especially in the case of illegal or non‐compliant disposal sites. When no environmental precaution is adopted, harmful substances' release imposes relevant health risk to the surrounding population.
