CFD Analysis of Dual‐Layer PCM Roofs for Thermal Mitigation in Residential Buildings

Heat Transfer, EarlyView.
ABSTRACT This study presents a computational fluid dynamics analysis of dual‐layer phase change material (PCM) roofs for passive cooling in residential buildings under the hot and humid climate of Bangladesh. A three‐dimensional transient model was developed in ANSYS Fluent using the enthalpy–porosity approach to simulate coupled heat conduction ...

Surface Chemical Analysis of Plastic Materials by X‐Ray Photoelectron Spectroscopy: Understanding Weathering, Fragmentation and Contaminant Uptake in Marine Environments

Macromolecular Materials and Engineering, EarlyView.
This Perspective demonstrates how X‐ray photoelectron spectroscopy (XPS) uncovers surface chemical changes in plastics, providing insight into weathering‐driven fragmentation and contaminant adsorption. The Perspective underscores XPS's pivotal role in elucidating fragmentation mechanisms, predicting pollutant–plastic interactions, and guiding ...

Polyolefin ductile-brittle transition temperature predictions by machine learning

Frontiers in Materials
Polymers show a transition from ductile-to brittle fracture behavior at decreasing temperatures. Consequently, the material toughness has to be determined across wide temperature ranges in order to determine the Ductile-Brittle Transition Temperature ...

Development of Fibrillar Morphology in a Polypropylene Under Time‐Dependent Shear Flow

Macromolecular Materials and Engineering, EarlyView.
The effects of isothermal, non‐constant flow on morphology development in iPP are studied. Two tests, applying the same total work but with different time evolution of the shear rate, are considered. The pattern of shear flow, not just the intensity, influences morphology.

Successive Mechanical Recycling of Poly(lactic Acid) by Injection Molding: Evolution of Molecular, Thermal, and Mechanical Properties

Macromolecular Materials and Engineering, EarlyView.
This study investigated how successive injection molding recycling affects the properties of poly(lactic acid) (PLA). Gel permeation chromatography showed a two‐thirds molar mass reduction after ten reprocessing cycles. Differential scanning calorimetry revealed lower glass transition and cold crystallization temperatures.

Effects of SUpport preparation on the perfonnance of the catalysts Ziegler-Natta based in TiCI4/MgCI2

Revista Técnica de la Facultad de Ingeniería, 2011
The properties of supported Ziegler-Natta catalysts depend mostly on the preparation of the support. Four kinds of Ziegler-Natta catalysts consisting of TIC4 supported on MgCh were prepared, differting mainly by the method used to prepare the support ...
