Development of Vertical Wind Turbine Blades Using 4D Printing of Composites

open access: yesPolymer Composites, EarlyView.
Vertical axis wind turbine: White blade: Commercial. Black blade: Composite. ABSTRACT This paper presents the procedure to make vertical wind turbine blades using the technique of 4D printing of composites (4DPC). The blades are made using carbon/epoxy composite materials with a fiber volume fraction of about 60%.

Quantifying Dual‐Color Photopolymerization in Xolography via Raman Spectroscopy

open access: yesJournal of Polymer Science, EarlyView.
A dual‐wavelength Raman spectroscopy workflow is presented for the quantitative assessment of dual‐color photoinitiators. Contrast and efficiency parameters are extracted from in situ curing curves and spatial Raman mapping is used to find inhomogeneities in printed objects.

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

open access: yesJournal 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 ...

Cytochrome P450 1A1 influences obesity‐induced pulmonary hypertension

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose The contribution of obesity to pulmonary arterial hypertension (PAH) pathophysiology remains poorly understood. Adipose tissue synthesises estrogens via cytochrome P450 (CYP) 19A1 (aromatase), whereas circulating estrogens are metabolised in the lung by CYP1A1.

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

open access: yesColoration 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

Assessment of Different Technologies in the Fabrication of 3D Printed Tooth Models for Dental Education

open access: yesEuropean Journal of Dental Education, EarlyView.
ABSTRACT Background 3D printing has emerged as a practical method for fabricating customisable, accurate and affordable dental training models. Numerous 3D printing technologies exist, though there is no standardised comparison to inform their implementation in dental education.
