Study of the Thermal and Hydrothermal Aging Effects on the Properties of 3D‐Printed Thermoplastic Polyurethane

Journal of Vinyl and Additive Technology, EarlyView.
Effect of post‐aging conditions on mechanical and thermal properties of FDM‐printed parts. ABSTRACT In this study, the thermal and hydrothermal aging of TPU produced with the FDM technique was simulated and subjected to a series of tests. The alterations in the internal structures of the samples that had been subjected to tensile, hardness, adhesive ...

‘The White Hordes From the West’: Race and Refuge in Australian Media Commentary About White Rhodesians During Zimbabwe's Decolonisation

Australian Journal of Politics &History, EarlyView.
ABSTRACT This article explores Australian media commentary on white Rhodesians migrating to Australia, focusing on the period of Malcolm Fraser's prime ministership (1975–1983). The main argument is that the Australian media debates about whether to classify white Rhodesians as ‘migrants’ or ‘refugees’ were not merely semantic but reflected a deeper ...

Investigation on high-temperature creep behavior at 300 °C in laser-welded joints of a novel heat-resistant Al alloy of Al–12Ce-0.4Sc

Journal of Materials Research and Technology
The scarcity of studies on the high-temperature creep behavior of laser welds in heat-resistant Al alloys limits their widespread application. This study examines the effects of laser welding and heat treatment on the high-temperature creep performance ...

From plant to fabric: Environmental opportunities associated with annatto dye for sustainable development in the textile industry

Coloration Technology, EarlyView.
Abstract Natural dyes are compounds that occur naturally in several organisms and are classified based on chemical structure and application method. The literature cites several natural dyes used in industrial transformation processes. Annatto dye is used in the food industry, and its biological pigment is extracted from the annatto seed. However, this

Enhancing the fastness characteristics of weld‐dyed cotton and recycled nylon 6,6 fabrics via sodium alginate and titanium dioxide

Coloration Technology, EarlyView.
Abstract This study investigates a sustainable dyeing and finishing strategy for recycled nylon 6,6 and organic cotton fabrics dyed with weld. Following meta‐mordant dyeing using alum under Natural Organic Dye Standard (NODS)‐compliant conditions, the fabrics were subjected to functional finishing with titanium dioxide as a multifunctional ...
